Description

Textile treatment composition for anti-yellowing

Technical field

[0001] The present invention refers generally to the field of textile treatment and more specifically textile detergents and textile care compositions. In particular, it relates to detergent compositions comprising specific mixtures of hydroxyl compounds and having improved antiyellowing performances.

[0002] More specifically, the present invention relates to textile treatment compositions, preferably detergents, that comprise a surfactant, an effective amount of alkanediols as boosting agents in combination with at least one further boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone, and optionally an enzyme, and the use of said textile treatment compositions for the preparation of a textile treatment preparation, preferably a detergent formulation/product. Additionally, the present invention relates to the use of these specific mixtures as defined herein for boosting the cleaning efficacy of a textile treatment composition and/or for reducing or even preventing the yellowing of textiles. Finally, the present invention relates to a method for boosting or improving the cleaning efficiency of a textile treatment composition and/or reducing the yellowing of textiles and/or preventing the yellowing of textiles by adding an effective amount of the specific boosting/anti-yellowing compositions as specified herein comprising at least one first boosting agent (alkanediols) in combination with at least one further (second) boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone, to said textile treatment composition.

Background art

[0003] One of the most persistent and troublesome problems arising during conventional laundering operations is the tendency of some coloured fabrics to release a dye or dyes into the laundering solution.

[0004] Changes in the colour impression of washed, that is to say clean, textiles, can also be based, on the one hand, on the fact that dye components are removed from the textile by the washing process, so-called “fading”, and on the other hand, dyes detached from differently coloured textiles can deposit on the textile, so-called “discolouration” or “dye transfer”. Additionally, textile articles can show a discolouration of the fabric caused by repeated use/wearing, laundering/washing or dirt, staining and aging. Further causes of discolouration are exposure to light, air, soil, and the natural degradation of the fibres over time. White or bright materials are often subject to greying or yellowing. However, it is desired that textiles keep their colour appearance.

[0005] In order to prevent such greying or yellowing the textiles are often treated with whitening agents such as bleaching agents such as for example sodium hypochlorite, optical brighteners (or optical brightening agents (OBAs) or fluorescent whitening agents), greying inhibitors, ultraviolet light protection agents, and the like. However, bleaches and the like further strain the textile fibres thereby shortening their lifetime. Another approach is based on the use of hueing dyes or of bluing dyes such as azo dyes, triaminotriphenyl methane compounds, triphenyl methane compounds and anthraquinone colourants in order to optically neutralize the yellow colour appearance of the textile.

[0006] However, these approaches require either harsh conditions, a plurality of chemicals and might cause a discolouration of the fabrics towards blue or greenish shades. Additionally, the addition of such substances generally leads to dulling of the textile fabrics and might even contribute to fabric yellowness as some optical brightening agents are sensitive materials and might degrade and cause a yellowing of the textiles themselves. Additionally, chlorine products are aggressive towards organic fibres such as wool thereby weakening the fibres and causing their yellowing. However, particularly in view of environmental aspects an overall reduction in the number of ingredients and less harsh conditions are required.

[0007] The detergent industry is permanently searching for ingredients which can resolve these negative aspects.

[0008] Attempts to prevent yellowing of clothes were also made by replacing common builders in detergents such as polyphosphates by zeolites, which however did not show the desired effect.

[0009] Other approached disclose the use of citrates as a main builder. However, the use of citrates does not efficiently prevent textiles from yellowing.

[0010] Thus, there is still an ongoing need for substances with the ability for improving the prevention or reduction of yellowing of textiles. More specifically, there is a need for preventing a discolouration of the textiles from the onset.

[0011] Accordingly, it is therefore an object of the present invention to provide multi-use textile treatment compositions with a superior anti-yellowing effect, and, thus, with an improved cleaning performance.

[0012] Furthermore, it is an object of the present invention to provide textile treatment compositions that provide better cleaning performances along with improved anti-yellowing properties compared to textile treatment compositions comprising a usual formulation and which are simultaneous gentler to the textile fibres, and which do not damage these fibres.

[0013] It is another object of the present invention to provide substances, which are capable of boosting or improving the cleaning efficiency of a textile treatment composition and/or reducing or even preventing the yellowing of textiles.

[0014] Finally, it is an object of the present invention, to provide a method for boosting or improving the cleaning efficiency of a textile treatment composition and/or reducing or even preventing the yellowing of textiles.

[0015] Surprisingly, it has been found that the addition of an effective amount of specific mixtures of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3-heptanediol or at least one other alkanediol as specified herein with at least one further boosting agents such as glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin and/or tropolone, as defined herein, to a textile treatment composition, has a positive influence on the cleaning performance and efficiently allows for a reduction/prevention of yellowing of textiles e.g. upon storage. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the mixtures of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3-heptanediol or of the at least one alkanediol as specified herein with glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin and/or tropolone as boosting compositions as specified herein. The above-mentioned substances efficiently overcome the undesirable yellowing of white and light-coloured fabrics, thus guaranteeing a clean and new-looking appearance. Surprisingly, mixtures of at least one alkanediol with glyceryl caprylate, 4-hydroxyacetophenone, tropolone and/or ethyl hexyl glycerin show excellent anti-yellowing properties without requiring further colour-protecting agents or harsh conditions. Simultaneously, yellowing is efficiently prevented even upon longterm storage of the textiles or their thermal treatment (e.g. ironing). Furthermore, these compositions according to the present invention allow for an improved cleaning effect without damaging the sensitive textile fibres.

[0016] In order to prevent yellowing no harsh conditions are required when using the compositions and preparations according to the present invention or when applying the method according to the present invention. The compositions and preparations according to the present invention are even applicable on an industrial scale (service industry including but not limited to hotels, motels, hospitals, nursing homes, restaurants, health clubs, and the like) or institutional scale. Since no harsh conditions are required in order to achieve a satisfying antiyellowing effect along with improved cleanness the compositions and preparations according to the present invention as well as the method disclosed herein are highly suitable for the treatment of sensitive textile fibres such as silk and can be used in large scale.

[0017] The compositions according to the present invention are particularly suitable for the treatment of white textiles as well as other light-coloured fabrics.

[0018] It was found that these boosting substances as specified herein show better cleaning efficiencies and anti-yellowing properties in a synergistical manner even when used in small amounts. Thus, based on the formulations as disclosed herein, the overall amount of ingredients such as builders or bleaches (and surfactants) can considerably be reduced, while simultaneously achieving excellent cleaning results along with considerably reduced yellowing.

[0019] Surprisingly it was found that the compositions according to the present invention exhibit a remarkable effect of inhibiting yellowing of textiles which is for example caused by iron components contained in the washing water, due to insufficient cleaning or other contaminations, e.g. from cosmetic products.

[0020] Preferably the compositions according to the present invention further comprise at least one builder. However, based on the formulations as disclosed herein, the overall amount of builders can considerably be reduced, while simultaneously achieving excellent cleaning results along with considerably reduced yellowing.

[0021] Additionally, based on the boosting effect in terms of cleaning performance the amount of surfactants and other wash-active substances in these textile treatment compositions can be reduced to achieve a similar cleaning effect.

[0022] The benefits of the compositions according to the present invention are based both on an improved cleaning performance (improved removal of discolouring substances) and the prevention or reduction of the degradation or oxidation of said discolouring substances which would otherwise lead to a yellowing of the textiles.

[0023] Additionally, the compositions according to the present invention further keep the stability of enzymes added to the composition over time. As the degradation or oxidation of the enzymes is supressed, the cleaning performance is maintained or even increased and simultaneously discolorations caused by the degradation or oxidation of the enzymes are efficiently prevented. Surprisingly, the mixtures of at least one first alkanediol boosting agent and at least one further (second) boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, tropolone, ethyl hexyl glycerin and mixtures of these further boosting agents, show a protective effect by increasing the stability of the enzymes in a synergistical manner.

[0037] In a further aspect, the present invention provides for a method of minimizing or preventing the yellowing of white or light-coloured textiles.

[0038] The present invention is specified in the appended claims. The invention itself, and its preferred variants, other objects and advantages, are however also apparent from the following detailed description in conjunction with the accompanying examples and figures.

[0039] All percentages are by weight unless otherwise indicated.

[0040] Numeric ranges recited within the specification and given in the form “x to y” include the values defining the range and include each integer within the defined range. When multiple preferred numeric ranges are specified in this format, all ranges created by combining the various endpoints are also included.

[0041] In the context of the present invention, the term “comprising” means that the named components are essential, but other components may be added and is still embraced by the present invention.

[0042] The term “consisting of’ as used according to the present invention means that the total amount of components (a) to (c) adds up to 100 % by weight, based on the total weight of the textile treatment composition, and signifies that the subject matter is closed-ended and can only include the limitations that are expressly recited.

[0043] Whenever reference is made to “comprising” it is intended to cover both meanings as alternatives, that is the meaning can be either “comprising” or “consisting of”, unless the context dictates otherwise.

[0044] In the context of the present invention, the term “at least one ...” or “one or more ...” means that the textile treatment composition according to the present invention can comprise either one or a mixture of two, three, four, five, six or even more different of the respective components following said term.

[0045] The term “and/or” expresses that a linkage exists, or an alternative is provided.

[0046] The term “optionally” means that the subsequently described component may but need not to be present in the textile treatment composition, and that the description includes variants, where the compound is included or variants, where the compound is absent.

[0047] As used herein, the term “alkyl” refers to saturated hydrocarbons having one or more carbon atoms, including straight-chain alkyl groups (such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, etc.), cyclic alkyl groups (or cycloalkyl or alicyclic or carbocyclic groups) (such as cyclopropyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, etc.), branched-chain alkyl groups (such as isopropyl, tert-butyl, sec-butyl, isobutyl, etc.) and alkyl substituted alkyl groups (such as cycloalkyl-substituted alkyl groups).

[0048] Unless otherwise specified, the term “alkyl” includes both unsubstituted alkyls and substituted alkyls. As used herein, the term “substituted alkyls” refers to alkyl groups having substituents, replacing one or more hydrogens on one or more carbons of the hydrocarbon backbone. Such substituents may include, for example, alkenyl, alkynyl, halogen, hydroxyl, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthiocarbonyl, alkoxyl, phosphate, phosphonate, cyano, amino, imino, sulfhydryl, alkylthio, arylthiol, thiocarboxylate, sulfates, alkylsulfinyl, sulfonates, nitro, etc.

[0049] The term “boosting” in the context of the present invention means “improving”, “enhancing”, “increasing”. Correspondingly, a “boosting agent” or a “boosting composition” is an agent or mixture of substances (composition) capable of “improving”, “enhancing”, “increasing” certain features or properties as defined herein, and in particular the anti-yellowing effect of the textile treatment composition.

[0050] The term “yellowing” (fabric or garment yellowing) in the context of the present invention refers to the change of the textile colour towards yellow nuances. This effect is particularly pronounced for bright or light-coloured textiles such as white textiles or pastel shades. Yellowing of textiles is usually caused by chemical and environmental factors as well as fabric ageing and is usually the result of unanticipated chemical degradation e.g. as a result of certain coloured decomposition products of the fibre itself or other chemicals such as textile care/finishing products, chemical additives thereof such as softeners, optical brighteners, enzymes or metallic salts, and the like. Furthermore, yellowing can be caused by contamination through consumer products such as cosmetics e.g., perfumes, body lotions, make-up, and the like.

[0051] Usually, yellowing is caused by the action of oxides of nitrogen (NO_X) on yellowable phenols and occurs after storage (“storage yellowing” due to improper storage), due to aging (e.g. by long term exposure to heat or light, fibre degradation) or as a result of insufficient cleaning or due to contaminations with (atmospheric) pollutants such as nitrogen oxides, sulfur dioxide, and ozone which might chemically interact with small amounts of chemical, oils or greases remaining on the fibres after washing. This effect is also referred to as “phenolic yellowing” or “elusive yellowing”. Phenolic yellowing is for example caused due to alkaline finishing, the presence of moisture, nitrogen dioxide present in the air, and storage in certain packaging materials such as in polyethylene bags or films containing the phenolic antioxidant butylated hydroxytoluene (BHT) or similar compounds.

[0052] A loss in whiteness or yellowing can also occur due to soil redeposition, body soils such as grease or sebum, or colouring from e.g. iron and copper ions. Also the oxidation of different enzymes present on the textile might cause yellowing.

[0053] Another reason for yellowing are, for example, iron containing stains, such as rust, or blood. Remaining iron can cause permanent yellowing of fabrics upon oxidation. However, any residual chemicals left on textiles due to improper cleaning might contribute to the yellowing during heat treatment.

[0054] Yellowing is normally accelerated by exposure to high heat, especially in the presence of high humidity levels, due to biological attack, high exposure to ultraviolet light, or long-term storage and the like.

[0055] These types of yellowing are based on the oxidation or degradation of the substances mentioned above which are either trapped within the textile fibres or in contact with those. This is different from yellow-coloured stains as such which are yellow in colour from the onset. The main cause for oxidation is heat and light radiation. Upon application of heat, e.g. during the ironing of textiles, these external substances trapped in the fibres are oxidized causing a yellow discolouration.

[0056] These yellowing effects are observed for all types of textile products, including those made from natural fibres such as cotton, wool, silk, and those based on synthetic fibres such as polyester, nylon, or spandex.

[0057] The compositions according to the present invention are particularly suitable for the treatment of white textiles, i.e. textiles being mostly white in colour, as well as light-coloured textiles.

[0058] Surprisingly it was found that the compositions according to the present invention exhibit a remarkable effect of inhibiting or reducing the yellowing of textiles which is for example caused by iron components contained in the washing water, due to insufficient cleaning or other contaminations, e.g. from cosmetic products and their oxidation as well as the oxidation or degradation of the detergent components as such which remain on the treated textiles.

[0059] Additionally, it was surprisingly found that the compositions according to the present invention efficiently reduce or even prevent the yellowing of textiles in a synergistical manner.

[0060] Moreover, it was observed that adding a mixture of boosting agents as specified above enhances the reduction and prevention of potential yellowing in a synergistical manner.

[0061] Surprisingly, it has been found that the addition of an effective amount of 1 ,2- heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3-heptanediol with at least one further boosting agent or a mixture of at least one alkanediol with at least one further boosting component such as glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone, as defined herein, to a textile treatment composition, has a positive influence on the reduction or prevention of yellowing in that they significantly enhance the cleaning performance and thus the removal of potentially discolouring components without causing damage to the textile fibres, i.e. without accelerating the fibre degradation. Moreover, it was surprisingly found that these mixtures of boosting agents efficiently improve the stability of enzymes comprised in the textile treatment composition, which additionally prevents or reduces yellowing by improving the cleaning performance as well as by preventing the degradation / oxidation of the enzyme which might cause yellowing. Moreover, it was surprisingly found that the mixture of at least one alkanediol with at least one further boosting agent efficiently prevents yellowing caused by long-term storage, fibre degradation / textile aging, contamination with (atmospheric) pollutants and the like.

[0062] Furthermore, it was found that the combination of an effective amount of a mixture of at least one alkanediol boosting agent with at least one further boosting agent (glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin and/or tropolone) as defined herein, and at least one surfactant provides for enhanced deep-cleaning performances. Due to the improved in-depth cleaning also invisible stains and residues of textile care/finishing products, chemical additives thereof such as softeners, optical brighteners or metallic salts, etc. as well as atmospheric pollutants, consumer contaminants or other contaminations which are trapped in the textiles and the fibres thereof can efficiently be removed. Based on the improved deep cleaning performance yellowing is efficiently prevented. Additionally, thereby, also potential oxidative processes will be reduced resulting in less yellowing. However, this deep-cleaning does not damage the fibres and does not require harsh conditions thereby additionally efficiently preventing and reducing potential yellowing of the textiles caused by fibre degradation.

[0063] The anti-yellowing effect achieved by the compositions according to the present invention is however not merely the result of an improved cleaning performance but is also based on the efficient reduction or prevention of the discolouration when using the composition as specified herein.

[0064] The reduction or prevention of potential yellowing is obtained by the specific combination of surfactants with the hydroxyl compound as specified herein, namely a mixture of at least one boosting agent selected from the group consisting of linear alkanediols having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol, and a further boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin, or tropolone, or a combination of these further boosting agents.

[0065] By adding a boosting agent mixture or boosting composition as specified herein to a textile treatment composition comprising at least one surfactant yellowing of the textiles can efficiently be prevented or at least reduced. As a result, yellowing, and, thus, discolouration does not occur or is at least minimized. Thus, the textile treatment compositions according to the present invention have a better cleaning performance compared to textile treatment compositions without the addition of the inventive mixtures of boosting agents. Based on the improved removal of atmospheric pollutants, chemical additives, consumer contaminants and the like yellowing is efficiently further reduced even under exposure of the textiles to high heat, especially in the presence of high humidity levels, biological attack, high exposure to ultraviolet light, or long-term storage. Additionally, no harsh chemicals need to be applied in order to achieve a high cleaning performance so that the overall amount of chemicals can be reduced without losing cleaning performance and without damaging sensitive fibres such as wool or silk. Thereby also accelerated aging and degradation of the textile fibres is prevented which otherwise would cause yellowing.

[0066] The composition according to the present invention has a good effect against yellowing and can meet the comprehensive requirements of the textile industry.

[0067] This effect is based on a synergism between the surfactant component and the boosting component as specified herein. Moreover, the (first) boosting agent and the further (second) boosting agent likewise are based on a synergistic interaction.

[0068] In addition, the compositions according to the present invention show an improved cleaning performance, thereby efficiently removing said discolouring substances and factors mentioned above. Moreover, the compositions according to the present invention efficiently prevent yellowing of textile fibres.

[0069] It was surprisingly found that the compositions according to the invention can efficiently be used as anti-yellowing formulations/agents, which can be incorporated into a broad range of product formulations such as detergents. [0070] The compositions, products and methods disclosed herein can be applied for treating a textile under industrial and institutional fabric care conditions in order to reduce or even prevent yellowing.

[0071] As used herein, the term “fabric care” relates to various fabric benefits including smoothness, shape maintenance, resilience, colour preservation, pilling control and others.

[0072] Surprisingly, the inventive textile treatment compositions such as detergents according to the present invention demonstrate an enhanced anti-yellowing effect in a broad washing temperature range from 30 °C to 95 °C.

[0073] The anti-yellowing boosting effect is demonstrated in the following examples by real washing/cleaning tests based on a visual evaluation. As shown in this disclosure, a use solution produced from the textile treatment composition according to the present invention, provides for a considerably reduced yellowing of the treated textiles compared to a corresponding composition without the addition of the inventive boosting agents even upon long-term storage of the textiles. This anti-yellowing boosting effect provides for a more effective textile treatment composition.

[0074] Beneficially, the anti-yellowing improvement further allows to reduce the amount of surfactants and additives and other auxiliaries commonly found in textile treatment compositions and thus the overall amount of ingredients. Because of the enhanced antiyellowing effect by the addition of the boosting agent mixture in the textile treatment compositions of the present disclosure, it is possible for the textile treatment compositions to use less ingredients while achieving a similar cleaning and/or anti-yellowing effect.

[0075] The terms “textile” and “fabric” are used synonymously herein.

[0081] The term “textile treatment composition” as contemplated herein, is understood to mean all products that are suitable and commonly used for washing or cleaning of textiles and fabric materials. Such compositions are usually composed predominantly of surfactants or a mixture of surfactants. Other than surfactant, the compositions normally consist of builders and chelating agents, co-builders and other polymer additives used for specific effects such as antiredeposition, dye transfer inhibition, rheology modification. Textile treatment compositions refer to compositions that find use in the removal of undesired compounds from textile and fabric items to be cleaned, such as laundry, carpets, curtains and the like. These deposits might be caused by soils or stains, germs and other contaminants. Detergents are the most commonly used cleaning compositions for textiles. The textile treatment compositions may be used for household cleaning, institutional cleaning and industrial cleaning. The textile treatment compositions can be used by the detergent composition itself or by a detergent product or by a use solution thereof. Additionally, textile treatment compositions also refer to textile care compositions such as softeners or post-wash treatment products and rinse products.

[0082] The textile treatment compositions according to the present invention are preferably used for boosting or improving the cleaning efficiency of a textile treatment composition and/or for reducing or preventing the yellowing of textiles or as anti-yellowing compositions.

[0083] The textile treatment compositions according to the present invention provide for both improved cleaning performance and reduced yellowing of textiles.

[0084] Within the scope of the present invention the terms “cleaning” and “washing” are used synonymously and refer to the reduction and/or removal of deposits, i.e. the removal of undesired stains and compounds from textile/fabric items to be cleaned.

[0112] The above specified surfactants can be used either singular or in the form of mixtures of two, three, or even more surfactants, either from the same surfactant category (anionic, cationic, non-ionic, amphoteric/zwitterionic) or as mixture of surfactants of different surfactant categories.

Boosting agent mixture / boosting composition / boosting component (b):

[0113] The textile treatment composition according to the present invention further includes at least one boosting component or mixture or composition (b). This component is also referred to as anti-yellowing component (or composition) or anti-yellowing boosting component (or composition).

[0114] Boosting agent mixtures (b) within the meaning of the present invention are mixtures of (b1.1) 1 ,2-heptanediol, (b2.1) 2,3-heptanediol, (b3.1) a mixture of 1 ,2-heptanediol and 2,3- heptanediol, (b¹) at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol with (b") glyceryl caprylate and/or (b^IH) 4-hydroxyacetophenone and/or (b^lv) ethyl hexyl glycerin and/or (b^v) tropolone.

[0115] Accordingly, the boosting component (b) is based on a mixture of at least one first alkanediol boosting component (first boosting agent / component) as specified herein and at least one second boosting component (further or second boosting agent / component) selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin, tropolone or any mixture thereof.

[0116] Surprisingly, mixtures of at least one alkanediol with at least one of glyceryl caprylate, 4-hydroxyacetophenone, tropolone and/or ethyl hexyl glycerin show excellent anti-yellowing and cleaning properties based on a synergistical interaction even when using small amounts of the inventive composition. Based on these boosting effects, the overall amount of ingredients such as other additives can be considerable reduced, thereby advantageously reducing the allergic potential of the final product formulation and its environmental impact. This improvement in the properties is based on a synergistical interaction between the at least one alkanediol (boosting agent) and the at least one further boosting agent as specified herein.

[0117] More specifically, mixtures (b) of the boosting agents as specified above were found to efficiently boost or improve the cleaning efficiency, i.e. they boost the cleaning performance of a textile treatment composition comprising at least one surfactant in a synergistical manner. This allows for a considerable reduction in the amount of the textile treatment product, such as a liquid or powdered laundry detergent to achieve the desired degree of cleanness. Simultaneously, the compositions according to the present invention are highly efficient in reducing, and also preventing, potential yellowing of the textile fibres which occurs over time, and which is primarily caused by oxidation or fibre degradation. Thus, the compositions according to the present invention are efficient anti-yellowing agents.

[0118] Alkanediols (b1.1), (b2.1), (b3.1), (b¹)

[0119] The first component of the boosting component or mixture (b) in the textile treatment composition [alkanediol component] according to the present invention is either 1 ,2- heptanediol (b1.1) or 2,3-heptanediol (b2.1), or a mixture comprising both heptanediols, i.e. 1 ,2-heptanediol plus 2,3-heptanediol (b3.1).

[0120] 1 ,2-Heptanediol belongs to the category of alkanediols and is a straight chain alkanediol with the general formula:

[0121] It has a carbon chain with 7 carbon atoms and the two functional OH-groups of the alkanediol are in alpha, beta-position and chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain.

[0122] 2,3-Heptanediol belongs to the category of alkanediols and is a straight chain alkanediol with the general formula:

[0123] It has a carbon chain with 7 carbon atoms and the two functional OH-groups of the alkanediol are in beta, gamma-position and chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain.

[0124] The first component of the boosting and/or anti-yellowing component (b) in the textile treatment composition according to the present invention is selected from the group consisting of:

(b¹) at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol.

[0125] In combination with at least one further or second boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin, tropolone or any mixture of these further boosting agents in the boosting and/or anti-yellowing component (b), these alkanediols or mixtures of alkanediols were found to exhibit extraordinary cleaning and anti-yellowing properties.

[0126] Alkanediols are glycols, i.e. any of a class of organic compounds belonging to the alcohol family; in the molecule of a glycol, two hydroxyl (-OH) groups are attached to different carbon atoms of a carbon chain.

[0127] Straight chain 1 ,2-alkanediols have been used for more than 15 years as multifunctional actives. Short chain 1 ,2-alkanediols are amphiphilic compounds and thus, like 1 ,2-pentanediol, 1 ,2-hexanediol and 1 ,2-heptanediol, are soluble both in water and oils. In contrast, 1 ,2-octanediol is a solid and tends to precipitate or recrystallize in oily solutions as well as in water at > 0.5 %. On the other hand, 1 ,2-decanediol is a solid and soluble only in oils. Apart from moisturizing, some 1 ,2-alkanediols are used as viscosity modifiers.

[0128] The boosting agent (b¹) of the textile treatment composition according to the present invention is in a first alternative at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms.

[0129] Moreover, in a second alternative of this aspect, the boosting component (b¹) may include a first linear alkanediol in combination with a second linear alkanediol, preferably at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and at least one second linear alkanediol having a carbon chain of 5 to 14 carbon atoms. Therefore, the invention also entails a mixture comprising a first and a second alkanediol as described herein.

[0130] Since the first linear alkanediol of the invention can be selected from the same lists and types of compounds as the linear alkanediol according to the first alternative of this aspect, in the following, reference is made to the linear alkanediol in general, which can also be the first linear alkanediol. In mixtures of first and second linear alkanediols, where these are specifically different, the specific terms “first” and “second” will be used to distinguish the two alkanediol components.

[0131] As used in this document, the phrase “at least one linear alkanediol” or “at least one first linear alkanediol” means that the composition can comprise one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or can comprise one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms or can comprise more than one linear alkanediol having a carbon chain of 5 to 14 carbon atom or more than one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms, i.e. two, three, four or more different linear alkanediols or first linear alkanediols having a carbon chain of 5 to 14 carbon atoms. [0132] The at least one linear alkanediol or the at least one first linear alkanediol according to the present invention consists of a chain of 5 to 14 carbon atoms joined to each other by single covalent bonds with two OH-functional groups attached to two different carbon atoms in the chain.

[0133] The at least one linear alkanediol or the at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the textile treatment composition according to the present invention is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, and tetradecanediol.

[0134] In a preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol has a carbon chain of 5 to 13 carbon atoms and is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol.

[0135] In a more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol has a carbon chain of 5 to 10 carbon atoms and is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, and decanediol.

[0136] In a preferred variant, the at least one linear or the at least one first linear alkanediol has a carbon chain of 5 to 9 carbon atoms in the textile treatment composition according to the present invention and is selected from the group consisting of pentanediol, hexanediol, octanediol, and nonanediol.

[0137] In a more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of alkanediols having a lower number of carbon atoms of 5 to 8, i.e. pentanediol, hexanediol, heptanediol, octanediol, and any mixture thereof, or is selected from the group consisting of alkanediols having a number of carbon atoms of 6 to 8, i.e. hexanediol, heptanediol, octanediol, and any mixture thereof, or is selected from the group consisting of alkanediols having a number of carbon atoms of 7 and 8, i.e. heptanediol, octanediol, and any mixture thereof.

[0138] In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of alkanediols having a higher number of carbon atoms of 9 to 14, i.e. nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, tetradecanediol and any mixture thereof, or is selected from the group consisting of alkanediols having a number of carbon atoms of 9 to 13, i.e. nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, and any mixture thereof, or is selected from the group consisting of alkanediols having a number of carbon atoms of 9 to 12, i.e. nonanediol, decanediol, undecanediol, dodecanediol, and any mixture thereof, or is selected from the group consisting of alkanediols having a number of carbon atoms of 9 to 11 , i.e. nonanediol, decanediol, undecanediol, and any mixture thereof, or is selected from the group consisting of alkanediols having a number of carbon atoms of 9 and 10, i.e. nonanediol, decanediol, and any mixture thereof. [0139] In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is either pentanediol, hexanediol, heptanediol, or octanediol, or any mixture thereof.

[0140] In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is either pentanediol, hexanediol, heptanediol, octanediol, nonanediol, or any mixture thereof.

[0141] In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is either nonanediol, decanediol, undecanediol, or dodecanediol, or any mixture thereof.

[0142] In a most preferred variant, the at least one linear alkanediol or the at least first linear alkanediol is heptanediol.

[0143] In a second alternative, the textile treatment composition according to the present invention comprises as first boosting agent a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediol having a carbon chain of 5 to 14 carbon atoms which is/are different from the first linear alkanediol.

[0144] This means that the (first) boosting agent component is an alkanediol mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more, i.e. two, three, four or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms. In this alternative, the first linear alkanediol can be any of the alkanediols as described herein for the linear alkanediol in general and in particular for the first alternative of this aspect.

[0145] For example, the mixture can include one first linear alkanediol and one, two, three or more second linear alkanediols; or the mixture can include two first linear alkanediols and one, two, three or more second linear alkanediols, etc. with the proviso, that in each mixture, the first linear alkanediols and the second linear alkanediols are different from each other.

[0146] The second linear alkanediol preferably consists of a chain of 5 to 14 carbon atoms joined to each other by single covalent bonds with two OH-functional groups attached to two different carbon atoms in the chain.

[0147] The at least one second linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the textile treatment composition according to the present invention is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0148] In a preferred variant, the at least one second linear alkanediol has a carbon chain of 5 to 13 carbon atoms and is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol. [0149] In a more preferred variant, the at least one second linear alkanediol has a carbon chain of 5 to 10 carbon atoms and is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, and decanediol.

[0150] In a more preferred variant, the at least one second linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol and nonanediol, most preferably heptanediol, octanediol and nonanediol.

[0151] The phrase “different from each other means” that the first linear alkanediols and the second linear alkanediols in the mixture are either different with regard to the length of their carbon chain, i.e. number of the carbon atoms, or with regard to their constitutional isomerism.

[0152] Likewise, the number of the carbon atoms of the first linear alkanediols and the second linear alkanediols in the mixture can also be same. For example, the first linear alkanediol and the second linear alkanediol have a carbon chain of 7 carbon atoms, but the first linear alkanediol and the second linear alkanediol are different with regard to their constitutional isomerism or with regard to their stereoisomerism.

[0153] If both the first and the second alkanediol is for example heptanediol, then the second linear alkanediol heptanediol is a different constitutional isomer or stereoisomer from the first linear alkanediol, according to the second alternative of this aspect.

[0154] In a preferred variant, the textile treatment composition according to the present invention comprises a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediol having a carbon chain of 5 to 14 carbon atoms wherein the number of the carbon atoms of the first and the second alkanediol is either same or different.

[0155] If both, the first and the second alkanediol have the same number of carbon atoms, such an alkanediol combination is herein also referred to as “homo alkanediol mixture” or “homo combination”. For example, the first linear alkanediol and the second linear alkanediol have a carbon chain of 7 carbon atoms, but the first linear alkanediol and the second linear alkanediol are different with regard to their constitutional isomerism or in regard to their stereoisomerism.

[0156] If the first and the second alkanediol have a different number of carbon atoms, such an alkanediol combination is herein also referred to as “hetero alkanediol mixture” or “hetero combination”. For example, the first linear alkanediol has a carbon chain of 7 carbon atoms and the second linear alkanediol has a carbon chain of 8 carbon atoms. However, beyond that, the first linear alkanediol and the second linear alkanediol can be different in regard to their constitutional isomerism or with regard to their stereoisomerism.

[0157] In a preferred variant the present invention relates to a textile treatment composition, wherein the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, and tetradecanediol; and/or the one or more second linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0158] Particular preferred is a boosting agent mixture, wherein the at least one first linear alkanediol is selected from an alkanediol having a lower number of carbon atoms from 5 to 8 and wherein the one or more second alkanediol is selected from an alkanediol having a higher number of carbon atoms from 9 to 14.

[0159] Most preferred is a boosting agent mixture, wherein the at least one first linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, and any mixture thereof, and the one or more second alkanediol is selected from the group consisting of nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, and any mixture thereof.

[0160] The term “alkanediol” within the context of the present invention also includes its constitutional isomers or position isomers. Constitutional isomers are compounds that have the same molecular formula and different connectivity. Position isomers, a particular form of constitutional isomerism, are structural isomers that can be viewed as differing only on the position of a functional group on a parent structure, which in this case, in particular, is the position of the two alcohol functions.

[0161] Depending on the number of the carbon atoms of the carbon chain of the alkanediol, there are various position isomers of the alkanediol: (x,x+ ^-constitutional isomers; (x,x+2)- constitutional isomers; (x,x+3)-constitutional isomers; etc. and alpha, omega-constitutional isomers when the alcohol functions are at the terminal ends of the carbon chain, wherein x stands for the number of the carbon atom in the alkanediol chain, to which the OH-groups of the alkanediol are chemically bonded. For example: if x is 1 , the two OH-groups of the alkanediol are chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain; if x is 2, the two OH-groups of the alkanediol are chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain, etc.

[0162] In the (x,x+ ^-constitutional isomers, the two OH functional groups are vicinal attached to two different adjacent carbon atoms in the chain. In the (x,x+2)-constitutional isomers, the two OH functional groups are attached to two different carbon atoms in the chain where the two carbon atoms are separated by one carbon atom. In the (x,x+3)-constitutional isomers, the two OH functional groups are attached to two different carbon atoms in the chain where the two carbon atoms are separated by two carbon atoms. In the alpha, omegaconstitutional isomers, the two functional groups are attached to the first carbon atom and to the terminal carbon atom.

[0163] In a preferred variant of the textile treatment composition according to the present invention, the linear alkanediol having a carbon chain of 5 to 14 carbon atoms, is preferably a vicinal (x,x+1)-diol, selected from the group consisting of a 1 ,2-diol, 2,3-diol, 3,4-diol, 4,5-diol, further (x,x+1)-diols, and mixtures thereof, preferably an alpha, beta-1 , 2-constitutional isomer.

[0164] In a preferred variant of the textile treatment composition according to the present invention, the at least one first linear alkanediol and/or the one or more second linear alkanediol having a carbon chain of 5 to 14 carbon atoms is a vicinal (x,x+ 1 )-diol , selected from the group consisting of a 1 ,2-diol, 2,3-diol, 3,4-diol, 4,5-diol, further (x,x+1)-diols, and mixtures thereof, preferably an alpha, beta- 1 ,2-constitutional isomer, and preferably the first linear alkanediol and/or the second linear alkanediol having a carbon chain of 5 to 14 carbon atoms is selected from 1 ,2-diols and/or 2, 3-diols.

1.2-nonanediol, and any mixture thereof.

[0188] It was found that said alkanediols show particular pronounced anti-yellowing boosting properties. Said alkanediols remarkably result in a better cleaning performance in a washing or cleaning process and provide for efficient ant-yellowing properties.

[0189] In a more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of 1 ,2-alkanediols having a lower number of carbon atoms of 5 to 8, i.e. 1 ,2-pentanediol, 1 ,2-hexanediol, 1 ,2-heptanediol, 1 ,2- octanediol, and any mixture thereof, or is selected from the group consisting of 1 ,2-alkanediols having a number of carbon atoms of 6 to 8, i.e. 1 ,2-hexanediol, 1 ,2-heptanediol, 1 ,2-octanediol, and any mixture thereof, or is selected from the group consisting of 1 ,2-alkanediols having a number of carbon atoms of 7 and 8, i.e. 1 ,2-heptanediol, 1 ,2-octanediol, and any mixture thereof.

[0192] It was found that these substances show particularly pronounced anti-yellowing properties.

Both, the improved anti-yellowing performance and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above-mentioned substances efficiently overcome the undesirable yellowing of white and light-coloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

Both, the improved anti-yellowing performance and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above- mentioned substances efficiently overcome the undesirable yellowing of white and lightcoloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0198] It was found that said alkanediols show particular pronounced anti-yellowing boosting properties. Said alkanediols remarkably result in a better cleaning performance in a washing or cleaning process and provide for efficient ant-yellowing properties.

[0201] In a most preferred variant, the at least one linear alkanediol or the at least first linear alkanediol is 2,3-heptanediol.

[0202] It was found that these substances show particularly pronounced anti-yellowing properties. In addition, it was found that these substances remarkably improve the removal of potentially discolouring substances/residues and show an overall improved cleaning performance. 2,3-Alkanediols having a lower number of carbon atoms are thus efficient for use as boosting agents in view of their anti-yellowing properties in textile treatment compositions. Both, the improved anti-yellowing performance and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein.

It was found that these substances show particularly pronounced antiyellowing properties. In addition, it was found that these substances remarkably improve the removal of potentially discolouring substances/residues and show an overall improved cleaning performance. Both, the improved anti-yellowing performance and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. T extiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above-mentioned substances efficiently overcome the undesirable yellowing of white and lightcoloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0224] It was found that said alkanediols show particular pronounced anti-yellowing boosting properties. Said alkanediols remarkably result in a better cleaning performance in a washing or cleaning process and provide for efficient ant-yellowing properties.

[0225] In a more preferred variant, the second linear alkanediol is selected from the group consisting of 1 ,2-alkanediols having a lower number of carbon atoms of 5 to 8, i.e. 1 ,2- pentanediol, 1 ,2-hexanediol, 1 ,2-heptanediol, 1 ,2-octanediol, and any mixture thereof, or is selected from the group consisting of 1 ,2-alkanediols having a number of carbon atoms of 6 to 8, i.e. 1 ,2-hexanediol, 1 ,2-heptanediol, 1 ,2-octanediol, and any mixture thereof, or is selected from the group consisting of 1 ,2-alkanediols having a number of carbon atoms of 7 and 8, i.e. 1 ,2-heptanediol, 1 ,2-octanediol, and any mixture thereof.

[0228] It was found that these substances show particularly pronounced cleaning efficiencies and anti-yellowing properties. Said substances are thus efficient for use as boosting agents in view of their anti-yellowing properties in textile treatment compositions within the meaning of the present invention. It was found that these substances (1 ,2-alkanediols having a lower number of carbon atoms) show particularly pronounced anti-yellowing properties. In addition, it was found that these substances remarkably improve the removal of potentially discolouring substances/residues and show an overall improved cleaning performance. Both, the improved anti-yellowing performance, and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above-mentioned substances efficiently overcome the undesirable yellowing of white and light-coloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0232] It was found that these substances show better cleaning efficiencies and antiyellowing properties. 1 ,2-Alkanediols having a higher number of carbon atoms, and more preferably more than 10 carbon atoms are thus efficient for use as boosting agents in textile treatment compositions within the meaning of the present invention. It was found that these substances show particularly pronounced anti-yellowing properties. In addition, it was found that these substances remarkably improve the removal of potentially discolouring substances/residues and show an overall improved cleaning performance. Both, the improved anti-yellowing performance and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above-mentioned substances efficiently overcome the undesirable yellowing of white and light-coloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0233] In an alternative preferred variant, the second linear alkanediol is selected from the group consisting of 2,3-alkanediols having carbon atoms of 5 to 9, i.e. 2,3-pentanediol, 2,3- hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, and any mixture thereof.

[0234] It was found that said alkanediols show particular pronounced anti-yellowing boosting properties. Said alkanediols remarkably result in a better cleaning performance in a washing or cleaning process and provide for efficient ant-yellowing properties.

[0235] In a still more preferred variant, the second linear alkanediol is selected from the group consisting of 2,3-alkanediols having a lower number of carbon atoms of 5 to 8, i.e. 2,3- pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, and any mixture thereof, or is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 6 to 8, i.e. 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, and any mixture thereof, or is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 7 and 8, i.e.

[0236] In a still more preferred variant, the second linear alkanediol is either 2,3-pentanediol or 2,3-hexanediol or 2,3-heptanediol or 2,3-octanediol or any mixture thereof. In a still more preferred variant, the second linear alkanediol is either 2,3-heptanediol or 2,3-octanediol or any mixture thereof.

[0237] In a most preferred variant, the second linear alkanediol is 2,3-heptanediol.

[0238] It was found that these substances show particularly pronounced anti-yellowing properties. In addition, it was found that these substances remarkably improve the removal of potentially discolouring substances/residues and show an overall improved cleaning performance. 2,3-Alkanediols having a lower number of carbon atoms are thus efficient for use as boosting agents in view of their anti-yellowing properties in textile treatment compositions. Both, the improved anti-yellowing performance, and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above-mentioned substances efficiently overcome the undesirable yellowing of white and light-coloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0239] In a still more preferred variant, the second linear alkanediol is selected from the group consisting of 2,3-alkanediols having a higher number of carbon atoms of 9 to 14, i.e. 2,3- nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3- tetradecanediol, and any mixture thereof, or is selected from the group consisting of 2,3- alkanediols having a number of carbon atoms of 9 to 13, i.e. 2.3-nonanediol, 2,3-decanediol,

2.3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, and any mixture thereof, or is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 9 to 12, i.e.

2.3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, and any mixture thereof, or is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 9 to 11, i.e. 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, and any mixture thereof, or is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 9 and 10, i.e. 2,3-nonanediol, 2,3-decanediol, and any mixture thereof.

[0240] In a still more preferred variant, the second linear alkanediol is either 2,3-nonanediol or 2,3-decanediol or 2,3-undecanediol or 2,3-dodecanediol or any mixture thereof.

[0241] According to a preferred variant, the second linear alkanediol is selected from the group consisting of 2,3-alkanediols having a higher number of carbon atoms, and more specifically more than 10 carbon atoms, i.e. 11, 12, 13 or 14 carbon atoms, i.e. 2,3- undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, or 2,3-tetradecanediol.

[0242] It was found that these substances show better cleaning efficiencies and antiyellowing properties. 2,3-Alkanediols having a higher number of carbon atoms, and more preferably more than 10 carbon atoms are thus efficient for use as boosting agents in view of their anti-yellowing properties in textile treatment compositions within the meaning of the present invention. Both, the improved anti-yellowing performance and improved stain and/or soil removal result in a better performance of the textile treatment composition in a washing or cleaning process. Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the boosting agent as specified herein. The above- mentioned substances efficiently overcome the undesirable yellowing of white and lightcoloured fabrics, thus guaranteeing a clean appearance without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0243] In a particular preferred variant, in the textile treatment composition according to the present invention, the linear alkanediol is selected from the group consisting of 1,2- pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1 ,2-octanediol, 1,2-nonanediol, 1 ,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1 ,2-tridecanediol, 1 ,2-tetradecanediol, and any mixture thereof.

[0244] In a particularly preferred variant, the textile treatment composition according to the present invention which comprises a mixture or a combination comprising at least one first linear alkanediol and one or more second linear alkanediol includes any one of the following mixtures/combinations:

■ a mixture comprising 1,2-pentanediol and 2,3-pentanediol; or

■ a mixture comprising 1,2-hexanediol and 2,3-hexanediol; or

■ a mixture comprising 1,2-heptanediol and 2,3-heptanediol; or

■ a mixture comprising 1,2-octanediol and 2,3-octanediol; or

■ a mixture comprising 1,2-nonanediol and 2,3-nonanediol; or

■ a mixture comprising 1,2-decanediol and 2,3-decanediol; or

■ a mixture comprising 1,2-undecanediol and 2,3-undecanediol; or

■ a mixture comprising 1,2-dodecanediol and 2,3-dodecanediol; or

■ a mixture comprising 1,2-tridecanediol and 2,3-tridecanediol; or

■ a mixture comprising 1,2-tetradecanediol and 2,3-tetradecanediol. [0245] In said homo alkanediol mixtures the first linear alkanediol and the second linear alkanediol have the same number of carbon atoms.

[0246] Particularly favourable is a mixture including 1 ,2-pentanediol in combination with 2,3- pentanediol, or a mixture including 1 ,2-heptanediol in combination with 2,3-heptanediol, or a mixture including 1 ,2-octanediol in combination with 2,3-octanediol and/or 3, 4-octanediol.

[0247] Due to their outstanding boosting effect in view of the anti-yellowing effect and improved cleaning efficiency a homo alkanediol mixture comprising 1 ,2-nonanediol and 2,3- nonanediol or a homo alkanediol mixture comprising 1 ,2-decanediol and 2,3-decanediol or a homo alkanediol mixture comprising 1 ,2-undecanediol and 2,3-undecanediol are most preferred.

[0248] The above specified homo alkanediol mixtures according to the present invention, comprising a 1 ,2-alkanediol and a 2,3-alkanediol are characterized by a synergistically intensified action, i.e. the alkanediol mixtures show increased cleaning performances along with remarkable anti-yellowing properties in a synergistic way compared to their respective single 1 ,2-alkanediol or 2,3-alkanediol substances. Simultaneously, these mixtures are highly efficient in reducing, and also preventing, potential yellowing of the textile fibres which occurs over time.

[0249] Said synergistic effect or action in improving the cleaning efficiency and simultaneously reducing and/or preventing the yellowing of textiles is found for the homo mixture including 1 ,2-pentanediol and 2,3-pentanediol.

[0250] Said synergistic effect in improving the cleaning efficiency and simultaneously reducing and/or preventing the yellowing of textiles is also observed for the homo mixture including 1 ,2-hexanediol and 2,3-hexanediol.

[0251] The homo mixture including 1 ,2-heptanediol and 2,3-heptanediol is particularly beneficial since it has a particularly pronounced synergistic effect on the cleaning and/or antiyellowing performance in a textile treatment composition. These mixtures are highly efficient in reducing, and also preventing, potential yellowing of the textile fibres which occurs over time.

[0252] The alkanediol mixture comprising 1 ,2-octanediol and 2,3-octanediol or the alkanediol mixture comprising 1 ,2-nonanediol and 2,3-nonanediol are particularly advantageous, since the mixtures are effective in synergistically cleaning and preventing yellowing when used in a textile treatment composition.

[0253] Also, the alkanediol mixture comprising 1 ,2-decanediol and 2,3-decanediol or the alkanediol mixture comprising 1 ,2-undecanediol and 2,3-undecanediol synergistically efficiently prevent yellowing.

[0254] An anti-yellowing effect is also observed for an alkanediol mixture including 1 ,2- dodecanediol and 2,3-dodecanediol or an alkanediol mixture including 1 ,2-tridecanediol and 2,3-tridecanediol. [0255] The afore-mentioned synergistically anti-yellowing effect combined with an improvement in the cleaning performance is particularly pronounced for the homo mixture including 1,2-heptanediol and 2,3-heptanediol or the homo mixture including 1 ,2-octanediol and 2,3-octanediol or the homo mixture including 1,2-nonanediol and 2,3-nonanediol.

[0256] The afore specified homo alkanediol mixtures including a 1 ,2-alkanediol and the corresponding 2,3-alkanediol display a remarkably synergistic activity and are clearly superior to the individually corresponding 1 ,2-alkanediols or 2,3-alkanediols and having the same concentration.

[0259] In said hetero alkanediol mixtures the first linear alkanediol and the second linear alkanediol have a different number of carbon atoms.

[0260] The afore specified alkanediol mixtures according to the present invention, comprising a first linear alkanediol and a second linear alkanediol, are characterized by synergistically intensified action, i.e. the alkanediol mixtures enhance the cleaning performance and show improved anti-yellowing properties in a synergistic way compared to the corresponding individual 1 ,2-alkanediol and/or 2, 3-alkanediol substances.

[0261] In a particular preferred variant, the textile treatment composition according to the present invention which comprises a mixture or a combination comprising at least one first linear alkanediol and one or more second linear alkanediol thus may include the following mixture/combination:

■ a mixture comprising 1 ,2-hexanediol and 1 ,2-octanediol.

[0262] Surprisingly, such hetero alkanediol mixtures have a particularly pronounced cleaning performance and remarkably reduce the occurrence of yellowing of textiles. These mixtures are highly efficient in reducing, and also preventing, potential yellowing of the textile fibres which occurs over time.

[0263] Beside the afore-described cleaning boosting effect, the afore specified hetero mixtures or combinations comprising at least one first linear alkanediol and one or more second linear alkanediol simultaneously have also a synergistic anti-yellowing efficacy, compared to the corresponding individual 1 ,2-alkanediol and/or 2, 3-alkanediol substances.

[0264] The above specified hetero alkanediol mixtures according to the present invention, comprising a first linear alkanediol and a second linear alkanediol, are characterized by synergistically intensified action, i.e. the alkanediol mixtures boost the cleaning power of a textile treatment composition in a synergistic way compared to the corresponding individual 1 ,2-alkanediol or 2,3-alkanediol substances.

[0265] Still more preferred is a boosting agent mixture, wherein the at least first linear alkanediol is selected from a 1 ,2-alkanediol having a lower number of carbon atoms from 5 to 8 and the one or more second alkanediol is selected from a 1 ,2-alkanediol having a higher number of carbon atoms from 9 to 14.

[0266] Most preferred is a boosting agent mixture, wherein the at least first linear alkanediol is selected from the group consisting of 1 ,2-pentanediol, 1 ,2-hexanediol, 1 ,2-heptanediol, 1 ,2- octanediol, and any mixture thereof, and the one or more second alkanediol is selected from the group consisting of 1 ,2-nonanediol, 1 ,2-decanediol, 1 ,2-undecanediol, 1 ,2-dodecanediol, 1 ,2-tridecanediol, 1 ,2-tetradecanediol, and any mixture thereof.

[0267] Most preferred is a boosting agent blend, wherein the at least one first linear alkanediol is selected from the group consisting of 1 ,2-alkanediols having a lower number of carbon atoms of 5 to 8, i.e. 1 ,2-pentanediol, 1 ,2-hexanediol, 1 ,2-heptanediol, 1 ,2-octanediol, and any mixture thereof, and the one or more second alkanediol is selected from the group consisting of 1 ,2-alkanediols having a higher number of carbon atoms of 9 to 13, i.e. 1 ,2- nonanediol, 1 ,2-decanediol, 1 ,2-undecanediol, 1 ,2-dodecanediol, 1 ,2-tridecanediol, and any mixture thereof.

[0268] Surprisingly, such alkanediol mixtures of short chain alkanediols and long chain alkanediols have a particularly pronounced cleaning and anti-yellowing effect.

[0269] More preferred are such alkanediol mixtures, wherein the difference between the number of carbon atoms of the at least first linear alkanediol and the number of carbon atoms of the one or more second alkanediol is at least 2 carbon atoms. In those alkanediol mixtures, short-chained and long-chained alkanediols are combined with each other resulting in improved anti-yellowing performances.

[0270] Still more preferred is a boosting agent mixture, wherein the difference between the number of carbon atoms of the at least first linear alkanediol and the number of carbon atoms of the one or more second alkanediol is at least 3 carbon atoms. With such alkanediol mixtures, the anti-yellowing performance is particularly pronounced.

[0271] Such combinations may include any of the following mixtures/combinations:

■ 1 ,2-pentanediol in combination with one of 1 ,2-octanediol, 1 ,2-nonanediol, 1 ,2- decanediol, 1 ,2-undecanediol, 1 ,2-dodecanediol, 1 ,2-tridecanediol, or 1 ,2- tetradecanediol; or

■ 1 ,2-hexanediol in combination with one of 1 ,2-nonanediol, 1 ,2-decanediol, 1 ,2- undecanediol, 1 ,2-dodecanediol, 1 ,2-tridecanediol, or 1 ,2-tetradecanediol; or

■ 1 ,2-heptanediol in combination with one of 1 ,2-decanediol, 1 ,2-undecanediol, 1 ,2- dodecanediol, or 1 ,2-tridecanediol, or 1 ,2-tetradecanediol; and

■ 1 ,2-octanediol in combination with one of 1 ,2-undecanediol, 1 ,2-dodecanediol, 1 ,2- tridecanediol, or 1 ,2-tetradecanediol. [0272] In a further preferred variant according to the present invention in the textile treatment composition the linear alkanediol is selected from the group consisting of 2,3-pentanediol, 2,3- hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3- undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and mixtures thereof.

[0273] In a more preferred variant of the textile treatment composition according to the present invention, the linear alkanediol is selected from the group consisting of 2,3- pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, and mixtures thereof.

[0274] Surprisingly, the addition of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol as well as other 2,3-alkanediols such as 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3- undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, and 2,3-tetradecanediol to a textile treatment composition result in a remarkable improvement of the cleaning power and an improved anti-yellowing effect, compared to the composition without the addition of an 2,3- alkanediol.

[0275] According to a particularly preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a carbon chain of 5 to 8 atoms, or a mixture comprising at least one first linear 1 ,2-alkanediol having a carbon chain of 5 to 8 carbon atoms and one or more second linear 1 ,2-alkanediols having a carbon chain of 5 to 8 carbon atoms, which is different from the first linear 1 ,2-alkanediol.

[0276] In a still more preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a carbon chain of 6 to 7 atoms, or a mixture comprising at least one first linear 1 ,2-alkanediol having a carbon chain of 6 to 7 carbon atoms and one or more second linear 1 ,2-alkanediols having a carbon chain of 6 to 7 carbon atoms, which is different from the first linear 1 ,2-alkanediol.

[0277] Surprisingly, it was found that these short-chained 1 ,2-alkanediols are particularly suitable boosting agents in terms of cleaning efficiency and anti-yellowing effect and which can also efficiently be incorporated into textile treatment compositions. It was found that these substances show better cleaning and anti-yellowing properties even after long term storage of the treated textiles even under exposure of the textiles to high heat, especially in the presence of high humidity levels, biological attack, high exposure to ultraviolet light. Such textile treatment compositions show improved cleaning and anti-yellowing properties compared to textile treatment composition without the addition of such substances. Additionally, no harsh chemicals need to be applied in order to achieve a high cleaning performance so that the overall amount of chemicals can be reduced without losing cleaning performance and without damaging sensitive fibres such as wool or silk. Thereby also accelerated aging and degradation of the textile fibres is prevented.

[0278] According to an alternative particularly preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a carbon chain of 5 to 9 atoms, or a mixture comprising at least one first linear 1 ,2-alkanediol having a carbon chain of 5 to 9 carbon atoms and one or more second linear 1 ,2-alkanediol having a carbon chain of 5 to 9 carbon atoms, which is different from the first linear 1 ,2-alkanediol.

[0279] It was found that said alkanediols show particular pronounced anti-yellowing boosting properties. Said alkanediols remarkably result in a better cleaning performance in a washing or cleaning process and provide for efficient ant-yellowing properties.

[0280] According to a particularly preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a carbon chain of 9 to 14 atoms, or a mixture comprising at least one first linear 1 ,2-alkanediol having a carbon chain of 9 to 14 carbon atoms and one or more second linear 1 ,2-alkanediols having a carbon chain of 9 to 14 carbon atoms, which is different from the first linear 1 ,2-alkanediol.

[0281] In a more preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a carbon chain of 10 to 13 atoms, or a mixture comprising at least one first linear 1 ,2-alkanediol having a carbon chain of 10 to 13 carbon atoms and one or more second linear 1 ,2-alkanediols having a carbon chain of 10 to 13 carbon atoms, which is different from the first linear 1 ,2-alkanediol.

[0282] In a still more preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a carbon chain of 11 to 12 atoms, or a mixture comprising at least one first linear 1 ,2-alkanediol having a carbon chain of 11 to 12 carbon atoms and one or more second linear 1 ,2-alkanediols having a carbon chain of 11 to 12 carbon atoms, which is different from the first linear 1 ,2-alkanediol.

[0283] Surprisingly, it was found that these long-chained alkanediols are particularly suitable boosting agents and which can also efficiently be incorporated into a broad range of textile treatment compositions. It was found that these substances show better cleaning efficiencies and significantly reduce the yellowing of textiles during storage by reducing the oxidation of potentially discolouring substances. Such textile treatment compositions show improved cleaning properties and allow for long-term stable colour appearances. Thus, such textile treatment compositions show improved anti-yellowing properties compared to corresponding textile treatment composition without the addition of such substances.

[0284] In a further preferred variant, the textile treatment compositions according to the present invention comprise at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a log Pow value of < 1 , or a mixture comprising at least one first linear 1 ,2-alkanediol having a log Pow value of < 1 and one or more second linear 1 ,2-alkanediol having a log Pow value of < 1 , which is different from the first linear 1 ,2- alkanediol. [0285] The 1 ,2-alkanediols having a log Pow value of < 1 are selected from the group consisting of 1 ,2-pentanediol (log Pow = 0.06), 1 ,2-hexanediol (log Pow = 0.58), 1 ,2- heptanediol (log Pow = 0.9), and any mixture thereof. Said 1 ,2-alkanediols are more soluble in water.

[0286] The Pow value is the partition coefficient of a chemical compound for the two-phase system consisting of the two immiscible solvents n-octanol and water at equilibrium. This value is therefore a comparison of the solubility of the solute in these two liquids. Hence the partition coefficient measures how hydrophilic or hydrophobic a chemical substance is.

[0287] The log Pow value is a constant defined in the following manner:

Log Pow = log 10 (Partition Coefficient)

Partition Coefficient, P = [n-octanol]/[water] where [ ] indicates the concentration of solute in the organic and/or aqueous partition.

The log Pow value is determined at a standard temperature of 25 °C.

[0288] The log Pow value < 1 means the compound has a higher affinity for the aqueous phase (it is more hydrophilic) and, thus, more soluble in water; a log Pow value > 1 denotes a higher concentration in the lipid phase (i.e. , the compound is more lipophilic) and, thus, more soluble in fat-like solvents.

[0289] Surprisingly, it was found that 1 ,2-alkanediols having a Pow value of < 1 are particularly suitable boosting agents within the meaning of the present invention, which can also efficiently be incorporated into a broad range of textile treatment compositions. In addition, it was found that the aforesaid 1 ,2-alkanediols exhibit outstanding improved cleaning properties in a textile treatment composition and provide for improved anti-yellowing efficiencies. Thus, textile treatment compositions comprising 1 ,2-alkanediols having a Pow value of < 1 show improved anti-yellowing properties compared to textile treatment composition without the addition of such 1 ,2-alkanediols.

[0290] In a still further preferred variant, the textile treatment composition according to the present invention comprises at least one boosting agent selected from the group consisting of at least one linear 1 ,2-alkanediol having a log Pow value of > 1 , or a mixture comprising at least one first linear 1 ,2-alkanediol having a log Pow value of > 1 and one or more second linear 1 ,2-alkanediol having a log Pow value of > 1 , which is different from the first linear 1 ,2- alkanediol.

[0291] The 1 ,2-alkanediols having a log Pow value of > 1 are selected from the group consisting of 1 ,2-octanediol (log Pow = 2.1), 1 ,2-nonanediol, 1 ,2-decanediol, 1 ,2- undecanediol, 1 ,2-dodecanediol, 1 ,2-tridecanediol, 1 ,2-tetradecanediol, and any mixture thereof. Said 1 ,2-alkanediols are more soluble in soluble in fat-like solvents, for example n- octanol.

[0292] Surprisingly, it was found that 1 ,2-alkanediols having a Pow value of > 1 are suitable boosting agents, which can also efficiently be incorporated into a broad range of textile treatment compositions. In addition, it was found that the aforesaid 1 ,2-alkanediols exhibit outstanding improved cleaning properties in a textile treatment composition and provide for improved anti-yellowing efficiencies. Thus, textile treatment compositions comprising 1 ,2- alkanediols having a Pow value of > 1 show improved anti-yellowing properties compared to textile treatment composition without the addition of such 1 ,2-alkanediols.

[0317] By these mixing ratios the afore mentioned alkanediol mixtures show a synergistically intensified anti-yellowing effect in comparison with the corresponding individual substances.

[0318] A preferred variant according to the present invention also encompasses a mixture including as first linear alkanediol 1 ,2-hexanediol and as second linear alkanediol 1 ,2- octanediol either in a ratio in a range of 50 : 50 to 99.9 : 0.1 , preferably in a ratio in a range of 75 : 25 to 99 : 1 , more preferred in a ratio in a range of 80 : 20 to 98 : 2 or still more preferred in a ratio in a range of 90 : 10 to 95 : 5.

[0319] Thus, according to another preferred variant, the present invention relates to a textile treatment composition as specified herein,

(i) wherein the mixture comprising 1 ,2-heptanediol and 2,3-heptanediol comprises the 1 ,2- heptanediol and the 2,3-heptanediol in a ratio in a range of 50 : 50 to 99.9 : 0.1 , preferably in a ratio in a range of 75 : 25 to 99 : 1 , more preferred in a ratio in a range of 80 : 20 to 98 : 2, still more preferred in a ratio of 90 : 10 to 95 : 5; or

[0320] According to an even more preferred variant, the present invention relates to a textile treatment composition as specified herein, wherein the mixture comprising at least one first linear alkanediol and one or more second linear alkanediol, as defined herein, comprises the first linear alkanediol and the second alkanediol in a ratio in a range of 50 : 50 to 99.9 : 0.1 , preferably in a ratio in a range of 75 : 25 to 99 : 1 , more preferred in a ratio in a range of 80 : 20 to 98 : 2, still more preferred in a ratio of 90 : 10 to 95 : 5.

[0321] By these mixing ratios the afore mentioned mixtures show a synergistical antiyellowing performance along with improved cleaning efficiencies of the textile treatment composition in direct comparison with the corresponding individual alkanediol substances.

[0322] The alkanediols are obtained either by synthesis from petrochemical or other fossil fuel sources by known methods such as olefin bishydroxylation, hydrolysis from epoxide or various chemical transformations or from bioderived feedstock by fermentation or from bio- based natural and renewable feedstock such as biomass by catalytic synthesis as it is described in US 2019/0241491 A1 and US 2020/0189995 A1. The alkanediols used according to the present invention comprise either petrochemically derived and biobased natural and renewable feedstock derived alkanediols. Preferably, the alkanediols are from bio-based sources and are thus bio-alkanediols.

[0323] Beyond the above specified alkanediols, the boosting composition (b) comprises at least one further boosting agent which is either (b") glyceryl caprylate, or (b^IH) 4- hydroxyacetophenone, or (b^lv) ethyl hexyl glycerin, or (b^v) tropolone, or any mixture of the aforementioned agents. This boosting component is also referred to as the second boosting agent or component.

[0324] Glyceryl caprylate, (b"):

is a natural emollient derived from glycerin and plant fatty acids, usually appearing as a white waxy solid. This ingredient is used in many skincare products for its emollient and moisturizing properties, to help maintain the balance of moisture in the skin. In additional, glyceryl caprylate (b¹¹) is used as antimicrobial active component in cosmetic preparations.

[0325] It was surprisingly found that the oily, surface-active co-emulsifier glyceryl caprylate is a further suitable boosting agent within the meaning of the present invention.

[0326] 4-Hydroxyacetophenone (4-HAP), (b¹¹¹):

possesses oxidation-inhibiting, fungicidal and bacterial growth-inhibiting properties and is therefore used to stabilize cosmetic preparations.

[0327] It was surprisingly found that the 4-HAP is a further suitable a boosting agent within the meaning of the present invention.

[0328] Ethyl hexyl glycerin (EHG), (b^lv):

is a relatively new cosmetic ingredient that is used for its surfactant, dispersant, emollient, skinconditioning and antimicrobial properties. Ethyl hexyl glycerin (EHG or octoxyglycerin) is a glyceryl ether and a vicinal diol.

[0329] It was surprisingly found that EHG is suitable to provide an anti-yellowing effect in textile treatment compositions within the meaning of the present invention.

[0330] Tropolone, (b^v):

is known for its antibacterial, antifungal, anti-inflammatory, antioxidant, and chelating properties and is therefore used in cosmetic formulations.

[0331] It was surprisingly found that tropolone act as anti-yellowing booster in textile treatment compositions within the meaning of the present invention.

[0332] The above specified further or second boosting agents (b") (b^IH), (b^lv) and (b^v) can be used either individually or in the form of mixtures of two, or even more of said boosting agents. Accordingly, in the boosting mixture / composition (b) at least one of the further (or second) boosting agents (b"), (b^IH), (b^lv) and (b^v) is comprised as a second component in addition to the at least one alkanediol component.

[0333] Similarly, the above specified single boosting agents (b") (b^IH), (b^lv) and (b^v) or mixtures or two or three boosting agents (b") (b^IH), (b^lv) and (b^v) can also be used in admixture with one or two alkanediol boosting agents (b¹) as defined herein. Preferably, such mixtures contain two, or even more boosting agents as defined herein.

[0334] Accordingly, the boosting component (b) is based on a mixture of at least one first alkanediol boosting component (first boosting agent / component) as specified above in combination with at least one second boosting component (further or second boosting agent / component) selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin, tropolone or any mixture thereof.

[0335] Preferably, the boosting component (b) is based on a mixture of at least one (first) alkanediol boosting component (first boosting agent / component) as specified above in combination with at least one further or second boosting component (further or second boosting agent / component) selected from the group consisting of glyceryl caprylate, 4- hydroxyacetophenone, tropolone or any mixture of these further boosting agents. According to an alternative variant, the boosting component (b) is based on a mixture of at least one (first) alkanediol boosting component (first boosting agent / component) as specified above in combination with at least one second boosting component (further or second boosting agent / component) selected from the group consisting of glyceryl caprylate, tropolone or any mixture thereof. [0336] In a particular preferred variant, the textile treatment composition according to the present invention the at least one boosting agent (b) includes any of the following mixtures/combinations:

[0338] Surprisingly, it was found that the above specified combinations are particularly efficient anti-yellowing compositions, which can also efficiently be incorporated into a broad range of textile treatment compositions. In addition, it was found that these mixtures/combinations show outstanding cleaning properties in a textile treatment composition. Thus, such textile treatment compositions show improved cleaning properties compared to textile treatment composition without the addition of such boosting combinations.

[0339] Surprisingly, for said boosting agent mixtures even a synergistic anti-yellowing boosting effect can be observed.

[0340] Most preferred, the textile treatment composition according to the present invention includes a mixture of boosting agents comprising an 1 ,2-alkanediol combined with 4- hydroxyacetophenone selected from the group consisting of:

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-pentanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-hexanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-heptanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-octanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-nonanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-decanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-dodecanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-tridecanediol;

■ a mixture comprising (b^IH) 4-hydroxyacetophenone and 1,2-tetradecanediol;

[0341] It was found that these boosting mixtures show an outstanding synergistic boosting effect in terms of cleaning and anti-yellowing properties in a textile treatment composition.

[0342] A particular pronounced synergistic anti-yellowing boosting effect can be observed for the following boosting agents:

■ 1,2-pentanediol;

■ 1,2-hexanediol;

■ 1,2-heptanediol;

■ 1,2-octanediol;

■ 1,2-nonanediol;

■ 1,2-decanediol;

■ 1,2-undecanediol;

■ 1,2-dodecanediol;

■ 1,2-tridecanediol;

■ 1,2-tetradecanediol; in combination with at least one of the following further boosting agents:

■ glyceryl caprylate;

■ 4-hydroxyacetophenone;

■ ethyl hexyl glycerin;

■ tropolone.

[0343] For the textile treatment composition according to the present invention, the list of boosting agents specified herein can be arbitrary combined with the list of surfactants specified herein.

[0344] It is surprisingly observed that adding a mixture of boosting agents as specified above can provide for an efficient anti-yellowing effect when combined with surfactants in a synergistical manner. Simultaneously, these combinations are highly efficient in reducing, and also preventing, potential yellowing of the textile fibres which occurs over time.

[0345] Without being bound by theory, it is assumed that the addition of a mixture of boosting agents as specified herein improves the cleaning power of the textile treatment composition, thereby allowing a more efficient removal of substances, which might cause yellowing of the textile fibres upon oxidation. In addition, the compositions according to the present invention efficiently allow for a reduction/prevention of yellowing of textiles in a synergistical manner e.g. upon storage. Textiles treated with the textile treatment compositions according to the present invention keep their original colour without obtaining a yellowish appearance even when stored for a long time.

[0346] The textile treatment compositions of the current disclosure are found, surprisingly, to have a superior cleaning performance. In order to prevent yellowing no harsh conditions are required when using the compositions and preparations according to the present invention or when applying the method according to the present invention. The method and compositions as disclosed herein are even applicable on an industrial scale and are even suitable for the treatment of sensitive textile fibres such as silk.

[0347] It was found that these substances show better cleaning efficiencies and antiyellowing properties even when used in small amounts. Thus, based on the formulations as disclosed herein, the overall amount of ingredients such as builders and other wash-active components as well as bleaching agents, blue pigments and optical brighteners can considerably be reduced, while simultaneously achieving excellent cleaning results along with considerably reduced yellowing without damaging the sensitive textile fibres.

[0348] Without being bound by theory, it is assumed that the combination of surfactants and boosting agents as specified herein allows for the prevention or suppression of the oxidation (due to light, heat etc.) of said discolouring substances. This effect is based on a synergism between the surfactant component and the boosting component as specified herein.

[0349] It was surprisingly found that the compositions according to the invention can efficiently be used as anti-yellowing formulations/agents.

[0350] Thus, in a preferred variant, the textile treatment composition according to the present invention comprises less of other components or is even free of further colour-related components such as bleaching agents, blue pigments and optical brighteners which are different to the boosting agent as specified above, such as a reduced amount of borate including ingredients.

[0351] A particular pronounced synergistic anti-yellowing effect can be observed for the following boosting agents:

■ 1 ,2-pentanediol;

■ 1 ,2-hexanediol;

■ 1 ,2-heptanediol;

■ 1 ,2-octanediol; in combination with at least one of the following further boosting agents:

■ glyceryl caprylate;

■ 4-hydroxyacetophenone;

■ ethyl hexyl glycerin;

■ tropolone.

[0352] For the textile treatment composition according to the present invention, the list of a boosting agents specified herein can be arbitrary combined with the list of surfactants specified herein.

Optional components

[0353] Enzymes / component (c), (c1), (c2), (c3):

[0354] The textile treatment composition according to the present invention can additionally comprise at least one enzyme or an enzyme formulation, comprising at least one enzyme as further component (c), (c1), (c2), (c3) that provide additional cleaning benefits.

[0355] Enzymes are known as effective chemicals for use with detergents and other cleaning agents to break down soils. Enzymes break down soils, make them more soluble, and enable surfactants to remove them from a surface to provide enhanced cleaning of a substrate. Specifically, enzymes can provide desirable activity for removal of, for example, protein-based, carbohydrate-based, or triglyceride-based stains from substrates such as textiles. In addition, enzymes also help to improve wash results at lower temperatures. As a result, enzymes have been used for various cleaning applications in order to digest or degrade soils such as grease, oils (e.g. vegetable oils or animal fat), protein, carbohydrate, or the like. For example, enzymes may be added as a component of a composition for laundry, textiles, ware washing, cleaning- in-place, cleaning drains, floors, carpets, medical or dental instruments, meat cutting tools, hard surfaces, personal care, or the like.

[0356] Enzymes suitable for the textile treatment compositions can act by degrading or altering one or more types of soil residues encountered on a fabric or textile thus removing the soil or making the soil more removable by a surfactant or other component of the cleaning composition. Both degradation and alteration of soil residues can improve detergency by reducing the physicochemical forces that bind the soil to the fabric or textile being cleaned, e.g., the soil becomes more water soluble. For example, one or more proteases can cleave complex, macro molecular protein structures present in soil residues into simpler short chain molecules which are, of themselves, more readily desorbed from surfaces, solubilized or otherwise more easily removed by detersive solutions containing said proteases.

[0357] Detersive enzymes according to the present invention have a cleaning, destaining or otherwise beneficial effect as a component of a solid textile treatment for laundry, textiles, carpets, or the like.

[0358] Enzymes that can be used according to the present invention include enzymes that provide desirable activity for removal of protein-based, carbohydrate-based, or triglyceride- based stains for laundry and textile cleaning and destaining; for carpet cleaning and destaining; and the like.

[0359] Suitable enzymes used according to the present invention are selected from the group consisting of proteases, amylases, lipases, cellulases, cutinases, gluconases, peroxidases, pectinases, mannanases, esterases, hemicellulases, xylanases, phospholipases, pectate lyases, keratinases, reductases, nucleases (including Dnase and/or Rnase), phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases, B-glucanases, arabinosidases, hyaluronidases, chondroitinase, oxidoreductases, and any mixture thereof.

[0360] The enzymes used according to the present invention are of any suitable origin, such as vegetable, animal, bacterial, fungal or yeast origin.

[0361] For the textile treatment composition according to the present invention, the list of boosting agents specified herein can be arbitrary combined with the list of enzymes specified herein. Moreover, for the textile treatment composition according to the present invention, the list of surfactants specified herein can be arbitrary combined with the list of enzymes specified herein.

[0362] Additionally, the compositions according to the present invention further keep the stability of enzymes added to the composition over time. As the degradation or oxidation of the enzymes is supressed, the cleaning performance is maintained or even increased and simultaneously discolorations caused by the degradation or oxidation of the enzymes are efficiently prevented. Surprisingly, the mixtures of at least one first alkanediol boosting agent and at least one further (second) boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, tropolone, ethyl hexyl glycerin and mixtures thereof, show a protective effect by increasing the stability of the enzymes in a synergistical manner.

[0363] Proteases: Any protease or mixture of proteases, from any source, can be used in the textile treatment compositions, provided that the selected enzyme is stable in the desired pH range (between about 6 and about 9). For example, the protease enzymes can be derived from a plant, an animal, or a microorganism such as a yeast, a mold, or a bacterium. Preferred protease enzymes include, but are not limited to, the enzymes derived from Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus. Protease enzymes derived from B. subtilis are most preferred. The protease can be purified or a component of a microbial extract, and either wild type or variant (either chemical or recombinant). Exemplary proteases are commercially available under the following trade names Alcalase®, Blaze®, Savinase®, Esperase®, and Progress UNO™, Liquanase® and Pristine®, each available from Novozymes; and Preferenz® P and Excellenz® P, each available from DUPONT/IFF.

[0364] Amylases: Any amylase or mixture of amylases, from any source, can be used in the textile treatment compositions, provided that the selected enzyme is stable in the desired pH range (between about 6 and about 9). For example, the amylase enzymes can be derived from a plant, an animal, or a microorganism such as a yeast, a mould, or a bacterium. Preferred amylase enzymes include, but are not limited to, those derived from a Bacillus, such as B. licheniformis, B. amyloliquefaciens, B. subtilis, or B. stearothermophilus. Amylase enzymes derived from B. subtilis are most preferred. The amylase can be purified or a component of a microbial extract, and either wild type or variant (either chemical or recombinant). Preferred amylases are commercially available under the trade names Stainzyme® and Amplify®, each available from Novozymes; and Preferenz® S, available from DUPONT/IFF.

[0365] Lipases: Any lipase or mixture of lipases, from any source, can be used in the textile treatment compositions, provided that the selected enzyme is stable in the desired pH range (between about 6 and about 9). For example, the lipase enzymes can be derived from a plant, an animal, or a microorganism such as a fungus or a bacterium. Preferred protease enzymes include, but are not limited to, the enzymes derived from a Pseudomonas, such as Pseudomonas stutzeri ATCC 19.154, or from a Humicola, such as Humicola lanuginosa (typically produced recombinantly in Aspergillus oryzae). The lipase can be purified or a component of a microbial extract, and either wild type or variant (either chemical or recombinant). Preferred lipases are commercially available under the trade names Lipex®, available from Novozymes, and Preferenz® L, available from DUPONT/IFF.

[0366] Cellulases: Any cellulase or mixture of cellulases, from any source, can be used in the textile treatment compositions, provided that the selected enzyme is stable in the desired pH range (between about 6 and about 9). For example, the cellulase enzymes can be derived from a plant, an animal, or a microorganism such as a fungus or a bacterium. Preferred cellulase enzymes include, but are not limited to, those derived from Humicola insolens, Humicola strain DSM1800, or a cellulase 212-producing fungus belonging to the genus Aeromonas and those extracted from the hepatopancreas of a marine mollusc, Dolabella Auricula Solander. The cellulase can be purified or a component of a microbial extract, and either wild type or variant (either chemical or recombinant). Preferred cellulases are commercially available under the trade names Celluclean® and Carezyme®, each available from Novozymes; and Revitalenz®, available from DUPONT/IFF.

[0367] Preferred enzyme selections depend upon the conditions of final utility, including the physical product form, use pH, use temperature, and soil types to be degraded or altered and are influenced by factors such as pH-activity and/or stability optima, thermostability, and stability to active detergents, builders and the like. The enzyme can be chosen to provide optimum activity and stability for any given set of utility conditions. In this respect, bacterial or fungal enzymes are preferred.

[0368] Protease enzymes, amylase enzymes and lipase enzymes are the most used enzymes in textile treatment compositions. The protease enzymes are particularly advantageous for cleaning soils containing protein, e.g. egg, milk, meat residue, or the like. The amylase enzymes are particularly advantageous for removing starch-based soils, such as pasta and rice. The lipase enzymes are particularly advantageous for cleaning soils including fat/grease.

[0369] As one skilled in the art shall ascertain, enzymes are designed to work with specific types of soils. For example, laundry applications may use a protease enzyme as it is effective at the high temperatures of the washing machines and is effective in reducing protein-based soils. Protease enzymes are particularly advantageous for cleaning soils containing protein, such as blood, cutaneous scales, mucus, grass, food (e.g. egg, milk, spinach, meat residue, tomato sauce), or the like.

[0370] According to the invention, the enzyme composition may be varied based on the particular cleaning application and the types of soils in need of cleaning. For example, the temperature of a particular cleaning application will impact the enzymes selected for an enzyme composition according to the invention. Laundry applications, for example, clean laundry at temperatures in excess of approximately 40 °C, or in excess of approximately 50 °C, or between approximately 65 °C to 95 °C, and enzymes such as proteases are desirable due to their ability to retain enzymatic activity at such elevated temperatures.

[0371] In a variant according to the present invention, the enzyme in the textile treatment composition is a single enzyme. In some other variants, the enzyme in the textile treatment composition is preferably an enzyme cocktail of two, three, four or even more different enzymes. Preferably, laundry detergents contain from two (preferably protease and amylase) to five or even to six enzymes.

[0372] Preferably, the at least one enzyme is selected from the group consisting of a protease, an amylase, a lipase, a gluconase, a cellulase, a peroxidase, or a mixture thereof.

[0373] In some variants, the enzyme in the composition is a protease, an amylase, a lipase, a cellulase, a gluconase, a peroxidase, a mannanase, or any mixture thereof.

[0374] Preferably the enzyme is a mixture of protease, an amylase, a lipase, a cellulase and/or pectate lyase.

[0375] Preferred detersive enzymes include a hydrolase such as a protease, an amylase, a lipase, or a combination thereof.

[0376] Preferably, the enzyme is a protease, amylase, lipase, cellulose, peroxidase, gluconase, or any mixture thereof.

[0377] In a still preferred variant, the enzyme in the textile treatment compositions disclosed here is a protease, amylase, lipase, or any mixture thereof.

[0378] Still more preferred, the enzyme is a protease, an amylase, or a mixture thereof.

[0379] Still more preferred, the enzyme is a protease, a lipase, or a mixture thereof. [0380] Still more preferred, the enzyme is selected from an amylase, a lipase, or a mixture thereof.

[0381] In some other embodiments, the enzyme is a protease.

[0382] In yet some other variant, the enzyme is an amylase.

[0383] In yet some other variant, the enzyme is a lipase.

[0384] In yet some other variant, the enzyme is a cellulase.

[0385] Preferred enzymes in solid textile treatment compositions according to the present invention include a protease, an amylase, a lipase, a cellulase, or a combination thereof.

[0386] Preferred enzymes in solid textile treatment compositions according to the present invention for laundry or textiles include a protease, a cellulase, a lipase, a peroxidase, or a combination thereof. Preferred enzymes in solid textile treatment compositions for carpets include a protease, an amylase, or a combination thereof.

[0387] For a stain remover, the enzymes are preferably selected from the group consisting of protease, amylase, lipase, mannanase, pectate lyase, and any mixture thereof.

[0388] For a fabric softener, the enzyme is preferably cellulase.

[0389] In order to increase the bleaching effect, oxidoreductases are added to the textile treatment composition according to the present invention.

[0390] The oxidoreductases are selected from the group consisting of oxidases, oxygenases, catalases, peroxidases, such as halo-, chloro-, bromo-, lignin-, glucose- or manganeseperoxidases, dioxygenases or laccases, such as phenoloxidases and polyphenoloxidases, and any mixture thereof.

[0391] Commercial enzymes are obtainable in liquid or dried form (i.e. puck, powder, etc.), are sold as raw aqueous solutions or in assorted purified, processed and compounded forms established in the prior art, and include about 0.1 % to about 80 % by weight active enzyme generally in combination with stabilizers, buffers, cofactors, impurities and inert vehicles. The actual active enzyme content depends upon the method of manufacture and is not critical; assuming the solid textile treatment composition has the desired enzymatic activity.

[0392] Preferably, the enzyme(s) are added to the textile treatment compositions either as single enzyme formulation, as enzyme cocktail formulation comprising a mixture of different enzymes or still more preferred as formulation in admixture with stabilizers, preferably with one or more enzyme stabilizers, buffers, and the like.

[0393] This includes for example the solid enzyme preparations obtained by granulation, extrusion or lyophilization or, particularly in the case of liquid or gel-like agents, solutions of the enzymes, advantageously as concentrated as possible, low in water and/or with added stabilizers. Alternatively, the enzymes can be encapsulated both for the solid and for the liquid administration form, for example by spray drying or extrusion of the enzyme solution together with a preferably natural polymer, or in the form of capsules, for example those in which the enzymes are enclosed, such as in a solidified gel, or in those of the core-shell type, in which an enzyme-containing core is coated with a protective layer that is impermeable to water, air, and/or chemicals. Further active substances, for example stabilizers, emulsifiers, pigments, bleaches or dyes, can additionally be applied in superimposed layers. Such capsules are applied using methods known per se, for example by vibratory or roll granulation or in fluidized bed processes. Advantageously, such granulates are low in dust, for example as a result of the application of polymeric film formers and are storage-stable on account of the coating. Furthermore, it is possible to package two or more enzymes together so that a single granulate exhibits multiple enzyme activities.

[0394] In a preferred variant according to the present invention, the enzyme is added to the textile treatment composition as a single enzyme.

[0395] In some other variants, the enzyme added to the textile treatment composition is preferably an enzyme cocktail of two, three, four or even more different enzymes. Typically, for laundry detergents an enzyme cocktail contains from two (preferably protease and amylase) to six enzymes.

[0396] Enzyme stabilizer:

[0397] The textile treatment composition according to the present invention optionally comprises at least one enzyme stabilizer, to further stabilize the enzyme in the textile treatment composition from loss of activity (i.e. retain proteolytic activity or enzymatic retention). The enzymes are stabilized by the further enzyme stabilizer through a physical protection by means of a protective layer.

[0398] In a more preferred variant, the at least one enzyme (c) is added to the textile treatment composition according to the present invention as enzyme formulation comprising an enzyme or a cocktail of different enzymes in mixture with one or more stabilizer(s), preferably with one or more enzyme stabilizers, and optionally buffers, additives, and the like.

[0399] The formulation of the textile treatment compositions may vary based upon the particular enzymes employed.

[0400] One group of stabilizers are reversible protease inhibitors. Benzamidine hydrochloride, borax, boric acids, boronic acids or their salts or esters are frequently used for this purpose, including in particular derivatives having aromatic groups. Typically, such enzyme stabilizers are used at levels in the compositions from 0.05 % to 5 %, more preferably from 0.075 % to 3 %, by weight of boric acid or other borate compound capable of forming boric acid in the composition (calculated on the basis of boric acid). Boric acid is preferred, although other compounds such as boric oxide, borax and other alkali metal borates (e.g., sodium ortho-, meta- and pyroborate, and sodium pentaborate) are suitable. Substituted boric acids (e.g., phenylboronic acid, butane boronic acid, and p-bromo phenylboronic acid) can also be used in place of boric acid. [0401] Also peptide aldehydes, i.e. oligopeptides having a reduced C-terminus, in particular those from 2 to 50 monomers, or hydrogen sulfite adducts thereof are used for this purpose. The peptidic reversible protease inhibitors include, but are not limited to, ovomucoid and leupeptin. Specific, reversible peptide inhibitors for the protease subtilisin and fusion proteins from proteases and specific peptide inhibitors are also suitable for this purpose.

[0402] Further enzyme stabilizers are amino alcohols such as mono-, di-, triethanol- and propanolamine and mixtures thereof, aliphatic carboxylic acids up to C12, such as succinic acid, other dicarboxylic acids or salts of the acids mentioned.

[0403] End-capped fatty acid amide alkoxylates are also suitable for this purpose.

[0404] Preferably, the enzyme stabilizer in the enzyme formulation is selected from the group consisting of polyols such as glycol, such as monopropylene glycol, glycerine, mannitol, isomaltol, lactic, sorbitol, xylitol, threitol, erythritol, arabitol; amino alcohols such as mono-, di- , triethanolamine and -propanolamine; aliphatic carboxylic acids up to C12, such as succinic acid and salts thereof; dicarboxylic acids and salts thereof; end-capped fatty acid amide alkoxylates; salts, preferably calcium and magnesium salts, such as calcium chloride, calcium formate, magnesium chloride, magnesium formate; reversible enzyme inhibitors such as borate-containing compositions, such as 4-FBPA, boron-free inhibitors, such as disubstituted alaninamide, sodium formate; and any mixture thereof.

[0405] The enzyme stabilizer or the enzyme formulation including the enzyme stabilizer is added to the textile treatment compositions in such amounts, that the enzyme stabilizer is present in the textile treatment compositions in an amount of 0.0001 % to 5 % by weight, based on the total weight of the textile treatment compositions. Preferably, the enzyme stabilizer is present in an amount of 0.001 % to 4 % by weight, based on the total weight of the textile treatment compositions. Most preferred, the textile treatment compositions include the enzyme stabilizer in an amount of 0.01 % to 3 % by weight, based on the total weight of the composition.

Optional further components

[0406] Within the context of the present invention, it is also possible, and in some cases advantageous, to combine the textile treatment compositions according to the present invention with other active substances and/or additives, depending on the purpose of the composition, in order to obtain a ready-for-use composition or formulation. The active ingredients provide desired properties and functionalities to the textile treatment compositions according to the present invention. The term “functional ingredient” or “functional additive” includes an ingredient that provides a beneficial property in a particular use. Some particular examples of functional ingredients are discussed in more detail below. However, a broad variety of other functional ingredients may be used.

[0407] The textile treatment compositions according to the present invention may comprise any of the ingredients customarily found in such compositions, such as, for example organic solvents, builders, and additional auxiliaries such as soil repellents, thickeners, colourants and fragrances or the like. [0408] Preferably, the textile treatment composition according to the present invention can advantageously be combined or varied with at least one active substance and/or at least one (functional) additive, such as for example anti-static agents, anti-wrinkling agents, antimicrobial agents, dye transfer inhibition agents (also called dye transfer inhibiting agents or dye transfer inhibitors) / colour protection agents, dye scavengers, dyes / colouring agents, greying inhibitors, odour removal / odour capturing agents, soil shielding / soil releasing agents, antiredeposition agents, ultraviolet light protection agents, fragrances, sanitizing agents, disinfecting agents, water repellency agents, insect repellency agents, anti-pilling agents, souring agents, mildew removing agents, allergicide agents, solubility modifiers, rheology modifiers / viscosity modifiers or thickeners, dispersing agents, water softeners, buffers, solvents, defoamers / foam inhibitors / suds suppressors, foam stabilizers, fabric softeners, starch agents, bleaching agents, bleach activators, bleach catalysts and bleach stabilizers, bleach scavengers, optical brighteners and ultraviolet light adsorbers, chelating agents / sequestrant agents, builders, co-builders, pH adjusters, stabilizers, hydrotropes, preservatives, fire proofing agents, shrinkage controllers, salts, and any mixtures thereof.

[0409] The textile treatment composition according to the present invention can for example comprise at least one anti-yellowing agent known in the state of the art.

[0410] Further commercially used anti-yellowing ingredients that can be added to the detergent itself are for example:

- Optical brighteners and UV absorbers: Optical brighteners are chemical compounds that absorb UV light and re-emit it as visible blue light. This can make fabrics appear whiter and brighter, masking any yellowing. Any optical brighteners or other brightening or whitening agents known in the art can be incorporated at levels typically from about 0.05 % to about 1.2 %, by weight, into the textile treatment compositions herein. Commercial optical brighteners which can be useful in the present invention can be classified into subgroups, which include, but are not necessarily limited to, derivatives of stilbene, pyrazoline, coumarin, carboxylic acid, methinecyanines, dibenzothiphene-5,5-dioxide, azoles, 5- and 6-membered-ring heterocycles, and other miscellaneous agents.

- Enzymes: Enzymes in laundry detergents, like protease and amylase, help break down protein-based stains (e.g., sweat, food) and starches, which can contribute to yellowing and are thus likewise considered anti-yellowing agents.

- Bleaching agents: Additionally bleaching materials can be incorporated into the compositions and/or products of the invention. Typically used bleaching agents are chlorine bleach or oxygen bleach (hydrogen peroxide or sodium percarbonate) can help remove yellow stains and whiten fabrics.

- Chelating agents: The textile treatment compositions disclosed herein can optionally contain one or more chelating agents, capable of complexing iron, manganese and/or calcium ions. This additionally allows for a softening of water. Chelating agents can help by binding to minerals and metal ions that can contribute to yellowing in hard water.

[0427] If required, the enzyme(s) is/are normally incorporated into the textile treatment composition according to the disclosure in an amount sufficient to yield effective cleaning during a washing procedure. An amount effective for cleaning refers to an amount that produces a clean textile Such a cleaning effect can be achieved with amounts of enzyme as low as about 0.02 % by weight of the textile treatment composition.

[0428] In the textile treatment compositions of the present disclosure, suitable cleaning can typically be achieved when an enzyme is present at about 0.0001 % to about 35 % by weight; preferably about 2 % to about 15 % by weight; preferably about 3 % to about 10 % by weight; preferably about 4 % to about 8 % by weight; preferably about 4 %, about 5 %, about 6 %, about 7 %, or about 8 % by weight. The higher enzyme levels are typically desirable in highly concentrated cleaning formulations.

[0429] In the textile treatment compositions of the present disclosure, suitable cleaning can typically be achieved when an enzyme is present in an amount of 0.0001 % to 5 % by weight, based on the total weight of the composition. Preferably, the enzyme is present in an amount of 0.0001 % to 4 % weight, based on the total weight of the composition.

Further preferred the enzyme is present in the textile treatment composition in an amount of 0.05 % to 2 % by weight, based on the total weight of the composition.

[0430] Typically, the enzyme (c), (c1), (c2), (c3) is present in the textile treatment composition according to the present invention in an amount of 0.05 % to 2.0 % by weight.

Textile treatment composition and products thereof

[0433] The anti-yellowing effect achieved by the compositions according to the present invention is however not merely the result of an improved cleaning performance but is also based on the efficient reduction or prevention of the discolouration when using the composition as specified herein.

[0434] The reduction or even prevention of potential yellowing is obtained by the specific combination of surfactants with the mixtures of hydroxyl compound as specified herein. The composition according to the present invention has a good effect against yellowing and can meet the comprehensive requirements of the textile industry.

[0435] Surprisingly it was found that textiles treated with the textile treatment compositions according to the present invention show improved yellowing resistances e.g. after washing.

[0436] Furthermore, it was found that the combination of an effective amount of a mixture of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3- heptanediol or at least one alkanediol as specified herein as a first boosting component with glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone, or any mixture of said further boosting agents as a further (or second) boosting component as defined herein, and at least one surfactant provides for enhanced deep-cleaning performances. Due to the improved in-depth cleaning also invisible stains and residues of textile care/finishing products, chemical additives thereof such as softeners, optical brighteners or metallic salts, etc. as well as atmospheric pollutants, consumer contaminants or other contaminations which are trapped in the textiles and the fibres thereof can efficiently be removed. Based on the improved deep cleaning performance yellowing is efficiently reduced and/or prevented in a synergistical manner.

[0437] Without wishing to being bound by theory, it is believed that the specific combination of 1 ,2-heptanediol, or 2,3-heptanediol, or a mixture comprising 1 ,2-heptanediol and 2,3- heptanediol, or of at least one alkanediol with substances such as, glyceryl caprylate, 4- hydroxyacetophenone, ethyl hexyl glycerin or tropolone, as defined herein, and at least one surfactant acts in a synergistical manner thereby creating an efficient barrier for efficiently preventing yellowing.

[0438] According to a further aspect of the present invention, the textile treatment composition according to the present invention is used as such or for the preparation of a textile treatment product or a textile treatment formulation.

[0439] The textile treatment compositions of the current disclosure are found, surprisingly, to have a superior cleaning performance and show efficient anti-yellowing properties, compared to compositions without the addition of an inventive boosting agent mixture as well as compared to the single boosting substances not used in combination.

[0440] Additionally, it was surprisingly found that the textile treatment composition according to the invention as such can advantageously be used for textile cleaning and/or textile care and/or as anti-yellowing agent/com position in the treatment of textiles.

[0441] The combination of a (first) boosting agent being at least one alkanediol and a further or second boosting agent being at least one of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin and/or tropolone in a textile treatment composition provides for an improved prevention/reduction of textile yellowing. Thus, the textile treatment compositions according to the present invention are particularly suitable detergents for laundry. Especially, the textile treatment compositions according to the present invention are particularly beneficial in preventing or minimizing the yellowing of white or light-coloured textiles.

[0442] The textile treatment compositions or products as specified herein can be employed in a variety of washing or cleaning methods. As used herein, the term “cleaning” refers to perform, facilitate, or aid in soil removal, bleaching, microbial population reduction, disinfection, etc. Preferably, the textile treatment compositions or products are useful for fabric care, textile cleaning, laundry, or other fabrics, namely for household, institutional and industrial application.

[0443] As used herein, the term “fabric cleaning” includes textile treatment compositions designed for cleaning soiled material. Such formulations include such compositions but are not limited to, laundry detergent compositions, fabric softening compositions, fabric enhancing compositions, fabric freshening compositions, laundry prewash, laundry pre-treat, laundry additives, spray products, dry cleaning agents or compositions, laundry rinse additive, wash additive, post-rinse fabric treatment, ironing aids, unit dose formulations, delayed delivery formulations, detergent contained on or in a porous substrate or nonwoven sheet, substrate having fibres preferably said fibres including active agents, and other suitable forms that may be apparent to one skilled in the art.

[0444] Thus, and based on the beneficial properties of the compositions disclosed herein the present invention further relates to textile treatment products comprising the textile treatment compositions according to the present invention.

[0445] Preferably, said textile treatment product is selected from the group consisting of fabric softeners, laundry cleaning compositions and detergents, fabric enhancing compositions, fabric freshening compositions, laundry pre-wash, laundry pre-treat, laundry additives, spray products, dry cleaning agents or compositions, laundry rinse additives, wash additives, post-rinse fabric treatments, ironing aids, and mixtures thereof.

[0446] Suitable examples of detergent products encompass heavy-duty detergents, colourcare detergents, light-duty detergents, all-purpose washing agents, fabric softeners, fabric laundry scents, scent lotions, laundry wipes, stain removers, bleach, laundry additives, and the like.

[0447] The afore-mentioned products preferably refer to a textile treatment composition in the form of a liquid, a solid, gelled, bar, paste, spray, tablet, encapsulated, diluted or concentrated form and optionally in two-compartment or multi-compartment form.

[0448] As used herein, liquid includes free-flowing liquids, as well as pastes, gels, foams and mousses. Non-limiting examples of liquids include textile treatment compositions in general, fabric enhancers, detergent gels commonly used for laundry, bleach and laundry additives. Gases, e.g. suspended bubbles, or solids, e.g. particles, may be included within the liquids.

[0449] A solid as used herein, includes powders, flakes, granules, pellets, tablets, microcapsules, beads, noodles, pearlized balls, lozenges, pucks, briquettes, bricks, blocks, or another solid form known to those of skill in the art.

[0450] A solid textile treatment composition or product can be provided as a pressed solid block, a cast solid block, an extruded pellet or block, or a tablet. Furthermore, a solid detergent composition or product may be provided in the form of a unit dose. A unit dose refers to a solid textile treatment composition unit sized so that the entire unit is used during a single washing cycle.

[0451] A solid textile treatment composition or product may also be provided in the form of a multiple use (e.g., multi-use) solid, such as, a block or a plurality of pellets, and can be repeatedly used to generate aqueous use solutions of the textile treatment such as a detergent composition for multiple cycles or a predetermined number of dispensing cycles. A multiple use solid detergent composition can be repeatedly used to generate an aqueous detergent composition, e.g., use solution, for multiple washing cycles. Pressed solid detergent blocks are made suitable to provide stability such that reactive components in the compositions do not react with each other until a point of dilution and/or use. In some aspects, the order of introducing the components to form the solid are non-limiting as there is minimal and/or no water introduced into the solid compositions. However, in some aspects, pressed solid detergent blocks are made by using a binding system to minimize any damage to the coated granules which may be employed. Beneficially, a pressing process to make the pressed solid detergent blocks generates a pressed solid detergent block and prevents the reaction or mix of the components. In an aspect of the disclosure, the solid detergent composition remains unreacted or unmixed until a point of use, e.g. dilution.

[0452] In a pressed solid process, a flowable solid, such as granular solids or other particle solids including binding agents are combined under pressure. In a pressed solid process, flowable solids of the compositions are placed into a form (e.g., a mould or container). The method can include gently pressing the flowable solid in the form to produce the solid cleaning composition.

[0453] The textile treatment compositions or products can be provided in concentrated form and diluted to a use solution or provided in a use solution. Preferably, the use compositions are diluted to a concentration between about 500 ppm and about 5000 ppm, more preferably between about 750 ppm and about 4500 ppm, most preferably between about 1000 ppm and about 4000 ppm.

[0454] The textile treatment compositions or products according to the present invention are used for household cleaning, medical cleaning, institutional cleaning, such as cleaning in schools, airport, hospitals, or industrial cleaning.

[0455] The textile treatment compositions or products according to the present invention can be prepared by combining and mixing the various ingredients according to usual and known methods. Mixing can be performed by any suitable automatic or manual method. For example, automatic or manual stirring can be performed. The textile treatment such as detergent compositions can be prepared in batch or continuous process.

[0456] Based on the advantageously effects, the present invention relates in a further aspect to the use of a mixture (b) of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2- heptanediol and 2,3-heptanediol or of:

(b¹) at least one boosting agent selected from the group consisting of at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol, as defined herein; and at least one further boosting agent selected from the group consisting of:

(b") glyceryl caprylate;

(b^IH) 4-hydroxyacetophenone;

(b^lv) ethyl hexyl glycerin;

(b^v) tropolone; and any mixture thereof; for boosting or improving the cleaning efficiency of a textile treatment composition and/or for reducing or preventing the yellowing of textiles and/or for preventing the yellowing of textiles.

[0457] Preferably, the present invention relates in a further aspect to the use of a mixture (b) comprising or consisting of:

(b") glyceryl caprylate;

(b^IH) 4-hydroxyacetophenone;

(b^lv) ethyl hexyl glycerin;

(b^v) tropolone; and any mixture of these further boosting agents; for boosting or improving the cleaning efficiency of a textile treatment composition and/or for reducing or preventing the yellowing of textiles and/or for preventing the yellowing of textiles.

[0458] Because of the boosting effect, the amount of other additives in a textile treatment composition can be reduced and the use of further wash-actives or optical brightener, bleaches, blue pigments and the like can be almost eliminated or at least reduced while providing for an efficient textile treatment composition.

[0459] It was surprisingly found that the addition of an effective amount of a mixture (b) of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3- heptanediol or at least one alkanediol boosting agent as specified herein with at least one further boosting agent selected from the group consisting of glyceryl caprylate, 4- hydroxyacetophenone, ethyl hexyl glycerin and/or tropolone, as defined herein, to a textile treatment composition, has a positive influence on the cleaning performance and efficiently allows for a reduction/prevention of yellowing of textiles e.g. upon storage. Textiles treated with the textile treatment compositions according to the present invention keep their original colour without obtaining a yellowish appearance even when stored for a long time. The above- mentioned substances efficiently overcome the undesirable yellowing of white and lightcoloured fabrics, thus guaranteeing a clean appearance.

[0460] Furthermore, surprisingly a mixture (b) of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3-heptanediol or at least one alkanediol boosting agent (b¹) in combination at least one further boosting agent as specified herein in combination with the surfactants as specified herein can be used as anti-yellowing agents. The use of the above mixtures of boosting substances in combination with at least one surfactant in a textile treatment composition prevents discolouration of textiles.

[0461] Thus, according to a preferred variant the present invention additionally relates to the use of compositions according to the present invention as anti-yellowing agents/compositions in the treatment of textiles.

[0462] Surprisingly, it has been found that the addition of an effective amount of a mixture (b) of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3- heptanediol or at least one alkanediol boosting agent (b¹) with at least one further boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone, as defined herein, to a textile treatment composition, has a positive influence on the suppression of discolouration of textile fibres. Additionally, they significantly enhance cleaning performance by efficiently removing potentially discolouring residues. Thus, yellowing or discolouration is efficiently prevented or at least minimized.

[0463] Finally, based on the advantageously effects, the present invention also relates to a method of boosting the cleaning efficiency of a textile treatment composition and/or reducing the yellowing of textiles and/or preventing the yellowing of textiles, comprising the steps of:

(ii) adding thereto an effective amount of a mixture (b) of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3-heptanediol or of:

(b") glyceryl caprylate;

(b^IH) 4-hydroxyacetophenone;

(b^lv) ethyl hexyl glycerin;

(b^v) tropolone; and any mixture thereof.

[0464] Preferably, the present invention also relates to a method of boosting the cleaning efficiency of a textile treatment composition and/or reducing the yellowing of textiles and/or preventing the yellowing of textiles, comprising the steps of:

(b") glyceryl caprylate; (b¹¹¹) 4-hydroxyacetophenone;

(b^lv) ethyl hexyl glycerin;

(b^v) tropolone; and any mixture of these further boosting agents.

[0465] During storage of textile treatment compositions, remaining residues of dirt, sweat and the like tend to oxidize e.g. upon ironing.

[0466] Surprisingly, it has been found that the addition of an effective amount of these mixtures of boosting agents as defined herein, to a textile treatment composition comprising at least one surfactant, has a positive influence on the reduction and prevention of yellowing while simultaneously enhancing the in-depth cleaning performance and thus the removal of potentially discolouring components without causing damage to the textile fibres, i.e. without accelerating the fibre degradation.

[0467] Surprisingly it was found that the compositions according to the present invention exhibit a remarkable effect of inhibiting yellowing of textiles which is for example caused by iron components contained in the washing water, due to insufficient cleaning or other contaminations, e.g. from cosmetic products and their oxidation.

[0468] Hence, the use or addition of mixtures of the afore-mentioned boosting substances to a textile treatment composition comprising at least one surfactant allows for the for an efficient cleaning and reduction of yellowing.

[0469] As shown in this disclosure, a use solution produced from the textile treatment composition according to the present invention, does not result in discolouration compared to a textile treatment composition without the addition of an inventive dye boosting agent(s). This boosting effect in terms of improved cleaning and reduced yellowing results in a more effective textile treatment composition.

[0470] Thus, the present invention is based on two effects: (i) improvement of the cleaning performance and efficient removal of potential discolouring residues, and (ii) prevention or reduction of the yellowing. Both effects result in an overall reduction of potential yellowing of white and light-coloured textiles. The effect is based on a synergism between the surfactant component and the boosting component as specified herein as well as a synergism between the (first) boosting agent and the further (second) boosting agent.

[0471] The present invention shall now be described in detail with reference to the following examples, which are merely illustrative of the present invention, such that the content of the present invention is not limited by or to the following examples. Examples

[0472] Example 1 :

[0473] The following tests are performed to show the boosting effect of the boosting agent mixtures as specified herein in terms of cleaning performance and the reduction and/or prevention of textile yellowing caused based on the oxidation of external residues trapped within the textile fibres.

[0474] The international standard ISO 105-X18 can be used to test the phenolic yellowing resistance index of the textile treated with the textile treatment compositions as disclosed herein. These are subsequently compared to common textile treatment compositions and compositions not comprising the mixture of boosting agents as specified herein.

[0475] The anti-yellowing boosting effect is demonstrated in the following examples by real washing/cleaning tests based on a visual or spectroscopic evaluation. As shown in this disclosure, a use solution produced from the textile treatment composition according to the present invention, shows considerably reduced yellowing of the treated textiles compared to a corresponding composition without the addition of the inventive boosting agent mixture. This anti-yellowing boosting effect results in a more effective textile treatment composition as well as in an improved enzyme activity.

[0476] Comparative tests were performed under the same conditions and were carried out for a comparable textile treatment composition but without the boosting agent mixture.

[0477] The evaluation of the degree of the prevention from yellowing can either be assessed

(A) Visually by a panel, or

(B) Using a spectrophotometer, or digital image analysis system to determine the whiteness degree W.

[0478] The anti-yellowing effect achieved by the compositions according to the present invention is however not merely the result of an improved cleaning performance but is also based on the efficient reduction or prevention of the discolouration when using the composition as specified herein.

[0479] The reduction of potential yellowing is obtained by the specific combination of surfactants with the mixtures of hydroxyl compounds as specified herein. The composition according to the present invention has a good effect against yellowing and can meet the comprehensive requirements of the textile industry.

[0480] Surprisingly it was found that textiles treated with the textile treatment compositions according to the present invention show improved yellowing resistances e.g. after washing.

[0481] The results demonstrate that a composition comprising a surfactant and an effective amount of a boosting mixture of the alkanediols as specified herein with glyceryl caprylate, 4- hydroxyacetophenone, tropolone and/or ethyl hexyl glycerin is especially useful as antiyellowing composition based on a synergistic anti-yellowing effect. [0482] Finally, it was found that the combination of at least one first boosting component based on alkanediols with at least one further second boosting component selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, tropolone and/or ethyl hexyl glycerin shows excellent cleaning properties. Simultaneously, these combinations of boosting agents allow for an efficient reduction or even prevention of yellowing of textiles. Surprisingly, these advantageous properties are more pronounced for the combination of the first boosting agent and the further second boosting agent compared to the single substances (i.e. alkanediols, glyceryl caprylate, 4-hydroxyacetophenone, tropolone and/or ethyl hexyl glycerin alone). This indicates a synergistic interaction between the alkanediol component and the further boosting component as specified herein.

[0483] Additionally, similar experiments were performed in order to show the anti-yellowing and cleaning properties of the present invention.
