Abstract

The invention is in the field of cleaning agents which contain stably formulated and ecologically harmless opacifying agents and their use for cleaning and/or disinfecting surfaces, in particular hard surfaces.

Description

The invention is in the field of cleaning agents which contain stably formulated and ecologically harmless opacifying agents and their use for cleaning and/or disinfecting surfaces, in particular hard surfaces.

In order to achieve an opaque, white appearance of a product, opacifiers and/or pearlescent agents can be added. There are numerous disclosures in the prior art on the use of such means.

Opacifiers are therefore distinguished by the fact that they give agents a non-shimmering, opaque, white appearance. Known opacifiers are styrene polymers, which are mostly used as styrene acrylates, styrene acrylamides or acrylates/PEG-10 maleates/styrenes. These polymers are present as particles and in this way cause the opaque, white appearance. In this context, reference can be made to the disclosures of the following documents: US2007/0128144A1, CN103767991B , OPULYN 301 Opacifier Technical Data Sheet (Form No. 324-00604-0914PS), OPULYN 303B Opacifier Technical Data Sheet (Form No. 324-00605-0914PS) and OPULYN 305 Opacifier Technical Data Sheet (Form No. 324-00607-0914PS). ).

However, the common opacifying agents, including the above-mentioned clouding particles, fall under the term “microplastics”, the use of which is ecologically questionable and which, accordingly, are to be largely avoided. Accordingly, consumer demand for microplastic-free products is steadily increasing.

An alternative possibility consists in the formulation of mineral opacifiers and pearlescent agents, as described, for example, in document WO2010/121876A1, where mica (mica) is used as an opacifier, and in the document WO2017/174756A1 , where the use of kaolin as an opacifying agent is disclosed. A major problem with mineral, particulate opacifiers, however, is that it is often not possible to achieve a stable formulation in the respective products, particularly over long periods of storage.

The object of the present invention was therefore to provide cleaning agents, in particular hand dishwashing detergents, which are characterized by an attractive cloudy/milky appearance, remain stable even over longer storage periods and also do not contain "microplastics", i.e. very small polymer particles.

As was surprisingly found, opacifiers based on wax bodies can be formulated in detergents, especially hand dishwashing detergents, providing opaque/milky-white, storage-stable products that are ecologically harmless compared to conventional cloudy detergents, especially hand dishwashing detergents. In particular, it was surprisingly found in this context that opacifiers formulated according to the present invention are compatible in combination with ingredients customary for hand dishwashing detergents, such as anionic surfactants, i.e. can be formulated to be storage-stable.

The mass-average molar mass M _w can also be determined by GPC, as described for M _n .

The agent according to the invention is an agent for cleaning and/or disinfecting hard surfaces, such as a liquid manual dishwashing detergent or an all-purpose cleaner. The term "hard surfaces" includes surfaces such as metal, glass, porcelain, ceramic, tile, stone, painted surfaces, plastics, wood and leather, but, in the context of the present invention, refers in particular to tableware, cutlery and cooking utensils. It is particularly preferably a hand dishwashing detergent which is used for manual dishwashing. In the context of the present invention, the term “hand dishwashing detergent” refers accordingly to cleaning agents which can be used for the manual cleaning of items to be washed, such as dishes, cutlery and cooking items. According to the invention, the agents described herein are liquid cleaning agents, i.e. in particular liquid hand dishwashing agents. In various embodiments, the liquid agents according to the invention can also be in the form of a unit dose, for example in the form of caps.

"Liquid" as used herein includes liquids and gels as well as pasty compositions. It is preferred that the liquid compositions are flowable and pourable at room temperature, but it is also possible for them to have a yield point.

"Phosphate-free" and "phosphonate-free", as used herein, means that the composition in question is essentially free of phosphates or phosphonates, i.e. in particular phosphates or phosphonates in amounts less than 0.1% by weight, preferably less than 0 .01% by weight, based on the respective composition.

1. a) mindestens ein Alkyl- und/oder Alkenyloligoglykosid,
2. b) mindestens ein Fettsäurepartialglycerid und gegebenenfalls
3. c) mindestens ein amphoteres Tensid.

A cleaning agent according to the invention contains at least one opacifying agent based on wax bodies, which contains an emulsifier mixture comprising:

1. a) at least one alkyl and/or alkenyl oligoglycoside,
2. b) at least one fatty acid partial glyceride and optionally
3. c) at least one amphoteric surfactant.

The weight ratio of a) and optionally c):b) should be between 6:1 and 3:1, preferably between 3.5:1 to 5:1 and in particular 4:1 to 4.7:1. In some embodiments, the weight ratio of the components (a + optionally c): b) is between 5:1 and 1.5:1 and in particular 3:1 to 2:1.

Mixtures based on wax bodies with alkyl oligoglycosides and partial glycerides within the above weight ratios result in opacifiers which have an advantageously small average particle size, as a result of which the desired milky opacity can be achieved particularly advantageously in the cleaning agents described herein. Other advantages of such products are their low viscosity, biodegradability, good flow and pumping properties and adequate storage stability.

Alkyl and/or alkenyl oligoglycosides

Alkyl and/or alkenyl oligoglycosides are known nonionic surfactants that follow formula (I): R ¹ O-[G] _p (I) in which R ¹ is an alkyl and/or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10. They can be obtained by the relevant methods of preparative organic chemistry. Representative of the extensive literature here is the review by Biermann et al. in "Starch/Stärke", 45, 281 (1993), B. Salka in "Cosm. Toil., 108, 89 (1993) and J. Kahre et al. referred to in "SÖFW-Journal", issue 8, 598 (1995).

The alkyl and/or alkenyl oligoglycosides can be derived from aldoses or ketoses having 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and/or alkenyl oligoglycosides are thus alkyl and/or alkenyl oligoglucosides. The index number p in the general formula (I) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and represents a number between 1 and 10. While p in a given compound must always be an integer, and here above all can assume the values p = 1 to 6, the value p for a specific alkyl oligoglycoside is an analytically determined, arithmetic value, which usually represents a fractional number. Alkyl and/or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From a performance point of view, preference is given to alkyl and/or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and is in particular between 1.2 and 1.4. The alkyl or alkenyl radical R ¹ can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and the technical mixtures thereof obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis. Preference is given to alkyl oligoglucosides with a chain length of C ₈ -C ₁₀ (DP=1 to 3), which are obtained as foreruns in the distillative separation of technical C ₈ -C ₁₈ coconut fatty alcohol and have a proportion of less than 6% by weight C ₁₂ - Alcohol can be contaminated as well as alkyl oligoglucosides based on technical C9/11 oxo alcohols (DP = 1 to 3). The alkyl or alkenyl radical R ¹ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and technical mixtures thereof, which can be obtained as described above. Alkyl oligoglucosides based on hardened C ₁₂ / ₁₄ coconut alcohol with a DP of 1 to 3 are preferred.

The preparations according to the invention can contain the alkyl and/or alkenyl oligoglycosides in amounts of 0.1 to 20% by weight, preferably 5 to 18% by weight and in particular 8 to 13% by weight, based in each case on the total weight of the opacifying agent.

Insbesondere werden längerkettige Partialglyceride z.B. basierend auf Ölsäure oder Stearinsäure eingesetzt insbesondere Gemische von Glyceriden auf Basis von gesättigten und ungesättigten Fettsäuren.Fatty acid partial glycerides, i.e. monoglycerides, diglycerides and their technical mixtures can still contain small amounts of diglycerides and triglycerides due to the production process. The partial glycerides preferably follow the formula (II),

in which R ² CO is a linear or branched, saturated and/or unsaturated acyl radical having 6 to 22, preferably 12 to 18 carbon atoms, R ³ and R ⁴ are each independently R ² CO or OH and the sum (m + n + p ) is 0 or numbers from 1 to 100, preferably 5 to 25, with the proviso that at least one of the two radicals R ³ and R ⁴ is OH.

In particular, longer-chain partial glycerides, for example based on oleic acid or stearic acid, are used, in particular mixtures of glycerides based on saturated and unsaturated fatty acids.

The opacifying agent contained according to the invention can contain the fatty acid partial glycerides in amounts of 0.1 to 5, preferably 1 to 3.5 and in particular 1.2 to 2.4% by weight, based in each case on the total weight of the opacifying agent.

Betaines are preferably used. Betaines are known surfactants which are mainly produced by carboxyalkylation, preferably carboxymethylation, of amine compounds. The starting materials are preferably condensed with halocarboxylic acids or their salts, in particular with sodium chloroacetate, one mole of salt being formed per mole of betaine. Furthermore, the addition of unsaturated carboxylic acids, such as acrylic acid, is also possible. For the nomenclature and in particular for the distinction between betaines and "true" amphoteric surfactants, reference is made to the article by U. Ploog in "Seifen-Ole-Fette-Wachse", 108, 373 (1982). Further overviews on this topic can be found, for example, by A. O'Lennick et al. in "HAPPI", Nov. 70 (1986), S. Holzman et al. in "Tens. surf Det., 23 , 309 (1986), R. Bibo et al. in Soap Cosm. Chem. Spec., Apr. 46 (1990) and P. Ellis et al. in "Euro Cosm.", 1, 14 (1994). Examples of preferably suitable betaines are the carboxyalkylation products of secondary and especially tertiary amines, which follow the formula (III):

Auch bei diesen Substanzen handelt es sich um bekannte Stoffe, die beispielsweise durch cyclisierende Kondensation von 1 oder 2 Mol Fettsäure mit mehrwertigen Aminen, wie beispielsweise Aminoethylethanolamin (AEEA) oder Diethylentriamin, erhalten werden können. Die entsprechenden Carboxyalkylierungsprodukte stellen Gemische unterschiedlicher, offenkettiger Betaine dar. Typische Beispiele sind Kondensationsprodukte der oben genannten Fettsäuren mit AEEA, vorzugsweise Imidazoline auf Basis von Laurinsäure oder wiederum C₁₂/₁₄-Kokosfettsäure, die anschließend mit Natriumchloracetat betainisiert werden.Furthermore, suitable starting materials for the betaines to be used according to the invention are also imidazolines which follow the formula (V):

in which R ⁵ is an alkyl group having 5 to 21 carbon atoms, R ⁶ is a hydroxyl group, an OCOR ⁵ or NHCOR ⁵ group and m is 2 or 3. These substances are also known substances which can be obtained, for example, by cyclizing condensation of 1 or 2 moles of fatty acid with polyvalent amines, such as aminoethylethanolamine (AEEA) or diethylenetriamine. The corresponding carboxyalkylation products are mixtures of different, open-chain betaines. Typical examples are condensation products of the abovementioned fatty acids with AEEA, preferably imidazolines based on lauric acid or again C _12/14 coconut fatty acid, which are then _betainized with sodium chloroacetate.

The opacifiers contained in the cleaning agents according to the invention can contain the amphoteric surfactants in amounts of 0 to 10, preferably 1 to 5 and in particular 2 to 4% by weight, based in each case on the total weight of the opacifier.

The selection of the wax body is not critical per se. Typical examples are alkylene glycol fatty acid esters, wax esters, hydrogenated triglycerides, saturated fatty alcohols containing 16 to 18 carbon atoms, ethylene oxide adducts of fatty acids containing 16 to 18 carbon atoms and/or paraffin waxes.

The use of ethylene glycol distearate is particularly preferred.

The opacifiers present according to the invention can contain the wax bodies, preferably alkylene glycol fatty acid esters, in amounts of 10 to 35, preferably 12 to 28 and in particular 15 to 25% by weight, based in each case on the total weight of the opacifier.

In various embodiments, an opacifier as described above has a solids content of 20 to 45% and in particular 30 to 41%, more preferably 35 to 37% by weight, based in each case on the total weight of the opacifier.

The opacifiers suitable according to the invention are water-based opacifiers. The water content is preferably approximately 20 to 80% by weight, preferably approximately 25 to 70% by weight, in particular approximately 30 to 65% by weight, based in each case on the total weight of the opacifying agent.

In various embodiments, one or more organic solvents may be included in addition to water. Preferred organic solvents come from the group of monohydric or polyhydric alcohols, alkanolamines or glycol ethers. The solvents are preferably selected from ethanol, n- or i-propanol, butanol, glycol, propane or butanediol, glycerol, diglycol, propyl or butyl diglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether , propylene glycol methyl, ethyl or propyl ether, dipropylene glycol methyl or ethyl ether, methoxy, ethoxy or butoxytriglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether and Mixtures of these solvents. If present, the proportion by weight of these organic solvents in the total weight of the opacifying agent is approximately 0.1 to 15% by weight, preferably 0.2 to 5.0% by weight and in particular 0.5 to 3.0% by weight. It is preferred, however, that the use of organic solvents is dispensed with.

In various embodiments, at least 85%, preferably 90% and particularly preferably 95% and in particular 99.9% of the opacifier particles have a diameter of <15 μm. The average particle diameter is preferably <15, particularly preferably <10 and in particular <7 μm.

In some embodiments, the content of the at least one opacifying agent, as defined and described above, is approximately 0.1 to approximately 12%, preferably approximately 0.5 to approximately 6% and in particular approximately 1 to approximately 3.5% by weight, in each case based on the total weight of the detergent.

In addition to the at least one opacifying agent, as defined above, a cleaning composition according to the invention, which is preferably a hand dishwashing detergent, also contains at least one surfactant.

Surfactants useful in the context of the present invention are known in the art and include anionic surfactants, cationic surfactants, nonionic surfactants, zwitterionic, amphoteric surfactants, and mixtures thereof.

In various embodiments, a cleaning agent according to the invention contains at least one anionic surfactant. The group of suitable anionic surfactants includes fatty alcohol ether sulfates. Fatty alcohol ether sulfates enable a stable foam volume in the presence of dirt, in particular greasy soiling on the surfaces to be cleaned or in water. Fatty alcohol ether sulfates are products of sulfation reactions on alkoxylated alcohols. The person skilled in the art generally understands alkoxylated alcohols to mean the reaction products of alkylene oxide, preferably ethylene oxide, with alcohols, in the context of the present invention preferably with longer-chain alcohols, i.e. with aliphatic straight-chain or mono- or poly-branched, acyclic or cyclic, saturated or mono- or poly- unsaturated, preferably straight-chain, acyclic, saturated alcohols having 6 to 22, preferably 8 to 18, in particular 10 to 16 and particularly preferably 12 to 14 carbon atoms. Depending on the reaction conditions, a complex mixture of addition products of different degrees of ethoxylation (n=1 to 30, preferably 1 to 20, in particular 1 to 10, particularly preferably 2 to 4) is generally formed from n moles of ethylene oxide and one mole of alcohol.

A further embodiment of the alkoxylation consists in using mixtures of the alkylene oxides, preferably the mixture of ethylene oxide and propylene oxide. Very particularly preferred for the purposes of the present invention are low-ethoxylated fatty alcohols having 1 to 4 ethylene oxide units (EO), in particular 1 to 2 EO, for example 2 EO such as Na-C ₁₂ -C ₁₄ fatty alcohols + 2 EO sulfate.

In some embodiments, the cleaning agent according to the invention, which is in particular a hand dishwashing detergent, contains one or more fatty alcohol ether sulfates, as defined above, preferably in an amount of from 5 to 20% by weight, in particular from 6 to 16% by weight, in each case based on the total weight of the agent.

Alkali metal salts of fatty alcohol sulfate are among the anionic surfactants that are also preferably present, particularly in hand dishwashing detergents. The agent according to the invention can preferably have 0.05 to 5% by weight, in particular 0.1 to 3% by weight, particularly preferably 0.3 to 1% by weight, of the alkali metal salt of a fatty alcohol sulfate, based on the total weight of the agent. This can be used as an additive that affects the foam volume. It has been shown that for water with a water hardness of 16 to 20° dH, i.e. hard water, a proportion of 0.05% by weight and in particular a proportion of 0.1% by weight is sufficient to to achieve only an insignificantly reduced foam volume compared to soft water. The harder the water, the higher the proportion of fatty alcohol sulfate should be. However, a proportion of more than 3% by weight, in particular more than 5% by weight, does not ensure any further stabilization of the foam, even in the case of very hard water with a water hardness of 20 to 32° dH. It has been shown that a proportion by weight of 0.3 to 1% by weight is sufficient to achieve the desired foam volume in both hard and very hard water with a water hardness of 16 to 32° dH, in particular 20 to 32° to get dH. A higher dosage of the alkali salt of the fatty alcohol sulfate would therefore only lead to an increase in costs, but not to a significantly larger foam volume. According to the invention, the fatty alcohol sulfate preferably has 12 to 14 carbon atoms, in particular 13 carbon atoms. The alkali salt is preferably a sodium salt. In particular, the alkali metal salt of the fatty alcohol sulfate is sodium lauryl sulfate. This can be used in technical purity, so that in addition to a fatty alcohol sulfate with 13 carbon atoms, there is a mixture of alkyl chains with a chain length of preferably 12 to 14 carbon atoms. For example, a sodium lauryl sulfate sold under the trade name ^Texapon® LS35 by BASF can be used.

The anionic surfactants which are also preferably present, particularly in hand dishwashing detergents, also include alkyl sulfonates. The alkyl sulfonates (INCI: sulfonic acids) usually have an aliphatic straight-chain or mono- or polybranched, acyclic or cyclic, saturated or mono- or polyunsaturated, preferably branched, acyclic, saturated alkyl radical with 6 to 22, preferably 9 to 20, in particular 11 to 18 and more preferably 14 to 17 carbon atoms.

Suitable alkyl sulfonates are therefore the saturated alkane sulfonates, unsaturated olefin sulfonates and - formally derived from the alkoxylated alcohols on which the alkyl ether sulfates are based - ether sulfonates, in which terminal ether sulfonates (n-ether sulfonates) with a sulfonate function attached to the polyether chain and internal ether sulfonates ( i-Ethersulfonates) with a sulfonate function linked to the alkyl radical. According to the invention, the alkanesulfonates, in particular alkanesulfonates with a branched, preferably secondary, alkyl radical, for example the secondary alkanesulfonate sec. Na-C ₁₃ -C ₁₇ alkanesulfonate (INCI: Sodium C ₁₄ - ₁₇ Alkyl Sec Sulfonate).

APG are nonionic surfactants and are known substances that can be obtained by the relevant methods of preparative organic chemistry. The index number x indicates the degree of oligomerization (DP degree), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While x in a given compound must always be an integer and here in particular the values x = 1 to 6, the value x for a specific alkyl glycoside is an analytically calculated value that is usually a fractional number. Alkyl glycosides with an average degree of oligomerization x of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to alkyl glycosides whose degree of oligomerization is less than 1.7 and in particular is between 1.2 and 1.6. Xylose is preferably used as the glycosidic sugar, but glucose is used in particular. The alkyl or alkenyl radical R' can be derived from primary alcohols having 8 to 18, preferably 8 to 14, carbon atoms. Typical examples are caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and the technical mixtures thereof obtained, for example, in the course of the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from ROELEN's oxosynthesis.

However, the alkyl or alkenyl radical R′ is preferably derived from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol or oleyl alcohol. Mention should also be made of elaidyl alcohol, petrolemyl alcohol, arachidyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and technical mixtures thereof.

Particularly preferred APG are not alkoxylated (a = 0) and satisfy the formula RO[G] _x , in which R as before represents a linear or branched, saturated or unsaturated alkyl radical having 4 to 22 carbon atoms, [G] represents a glycosidically linked sugar radical, preferably glucose residue, and x is a number from 1 to 10, preferably 1.1 to 3, in particular 1.2 to 1.6. Correspondingly preferred alkyl polyglycosides are, for example, C _8-10 - and a C _12-14 -alkyl polyglucoside with a DP degree of 1.4 or 1.5, in particular C _8-10 -alkyl-1,5-glucoside and C _12-14 -alkyl-1,4-glucoside.

For an optimal antimicrobial effect, at least one of the radicals preferably has a chain length of 8 to 18, in particular 12 to 16, carbon atoms. QAC can be produced by reacting tertiary amines with alkylating agents such as methyl chloride, benzyl chloride, dimethyl sulfate, dodecyl bromide, but also ethylene oxide.

Enzymes can advantageously be used in amounts of 0.0001 to 5% by weight, in particular in amounts of 0.001 to 1.5% by weight, preferably in amounts of 0.01 to 1.0% by weight, based on the Total weight of the washing and / or care products are used.

The protein concentration can generally be determined using known methods, for example the BCA method (bicinchoninic acid; 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the Biuret method (A.G. Gornall, C.S. Bardawill and MM David, J. Biol Chem., 177 (1948), pp. 751-766). In this regard, the active protein concentration can be determined by titrating the active centers using a suitable irreversible inhibitor and determining the residual activity (cf. M. Bender et al., J. Am. Chem. Soc. 88, 24 (1966), p. 5890 -5913).

In a preferred embodiment, the agent according to the invention contains at least one perfume and/or at least one fragrance. All perfumes and/or fragrances known to the person skilled in the art can be used, with the proviso that they essentially do not adversely affect the properties of the cleaning agent.

All substances and mixtures known for this purpose can be used as fragrances or fragrances or perfume oils. For the purposes of this invention, the terms “fragrance(s)”, “fragrances” and “perfume oil(s)” are used synonymously. This means in particular all those substances or mixtures thereof which are perceived by humans and animals as an odour, in particular by humans as a pleasant odour.

In order to be perceptible, a fragrance must be volatile, with the nature of the functional groups and the structure of the chemical compound also having an important role to play in terms of molecular weight. Thus, most fragrances have molar masses of up to about 200 daltons, while molar masses of 300 daltons and above tend to be an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions are divided into "top note" (top note), "middle note or middle note" (middle note or body) and "base note" (end note or dry out). Analogous to the description in the international patent publication WO 2016/200761 A2 can top, middle and base notes based on their vapor pressure (using the in the WO 2016/200761 test methods described) can be classified as follows:

It may be desirable to keep the active ingredients that have a positive effect on the feel of the skin or other sensitive active ingredients, such as perfumes, separate from the actual agent until use. An elegant method for incorporating such sensitive, chemically or physically incompatible or volatile ingredients is the use of microcapsules in which these ingredients are enclosed in a stable manner for storage and transport and from which they are mechanically, chemically, thermally or enzymatically released for or during use . In a preferred embodiment, therefore, one or more of the active ingredients and/or perfumes and/or fragrances which have a positive effect on the feel of the skin are incorporated wholly or partially into microcapsules.

Microcapsules are finely dispersed liquid or solid phases coated with film-forming polymers, during the production of which the polymers are deposited on the material (active ingredient) to be coated after emulsification and coacervation or interfacial polymerization. Here, the active ingredient is encased in a shell-like manner by a solid membrane (microcapsule in the narrower sense) or enclosed by a matrix (microsphere or sphere). In the following, the term microcapsule is used in the general sense for both variants. Such capsules are usually microscopically small (< 50 µm) and are sometimes also referred to as nanocapsules or nanospheres, they can be dried like powder. However, larger capsules or beads (>0.5 mm) that are visible to the naked eye and filled with active ingredients can also be produced. When incorporated into the hand dishwashing detergent according to the invention, these offer an additional visual attraction if the capsules are distributed in a stable suspension, which can be achieved by selecting suitable surfactants and thickeners and setting a suitable viscosity.

All surfactant-stable capsules and capsule materials or spheres and sphere materials available on the market can be used as microcapsules, such as the commercially available Primasphere® (chitosan and agar or carboxymethylcellulose) and Primasponge® (alginate, chitosan, agar) from BASF, Hallcrest Microcapsules ® (gelatin, gum arabic) from Hallcrest, Inc. (US), Coletica Thalaspheres® (maritime collagen) from Coletica (FR), Lipotec Millicapseln® (alginic acid, agar-agar) from Lipotec S.A. (ES), Induchem Unispheres® (lactose, microcrystalline cellulose, hydroxypropylmethylcellulose) and Unicerin® C30 (lactose, microcrystalline cellulose, hydroxypropylmethylcellulose) from Induchem AG (CH), Kobo Glycospheres (modified starch, fatty acid esters, phospholipids) and Softspheres® (modified Agar-Agar) from Kobo (US) and Kuhs Probiol Nanospheres (phospholipids) from Kuhs (DE) and others. The microcapsules can have any shape within the production-related scope, but they are preferably egg-shaped or ellipsoidal in shape or, in particular, approximately spherical. Depending on the active ingredient and application, the diameter along its greatest spatial extent can be on average between 100 nm (not visually recognizable as a capsule) and 10 mm. The preferred mean diameter is in the range between 0.1 mm and 7 mm, microcapsules with a mean diameter between 0.4 mm and 5 mm being particularly preferred. Dyes, color pigments or pearlescent components can also be added to improve the appearance.

The active substance can be released from the microcapsules mechanically either by crushing the microcapsules during the cleaning process or by breaking them open using a suitable metering device. Other possibilities are the release of the active substance by changing the temperature (putting it into warm washing up liquid), by shifting the pH value, changing the electrolyte content, etc.

If microcapsules are used, their content is usually from 0.01 to 10% by weight, preferably from 0.1 to 5% by weight, in particular from 0.2 to 3% by weight and extremely preferably from 0.3 to 2% by weight -%, wherein the cleaning agent according to the invention can contain only microcapsules of the same type or mixtures of different types of microcapsules.

In general, the pH of an agent can be adjusted by using standard pH regulators. In various embodiments, the pH of the compositions described herein is in a range from 3.5 to 12, preferably from 3.7 to 10.0, preferably greater than 4.0, in particular from 4.0 to 9.0. Acids and/or alkalis, preferably alkalis, are used as pH adjusters. Suitable acids are, in particular, organic acids such as acetic acid, citric acid, glycolic acid, lactic acid, succinic acid, adipic acid, malic acid, tartaric acid and gluconic acid or amidosulfonic acid. In addition, however, the mineral acids hydrochloric acid, sulfuric acid and nitric acid or mixtures thereof can also be used. Suitable bases come from the group of alkali metal and alkaline earth metal hydroxides and carbonates, in particular the alkali metal hydroxides, of which potassium hydroxide is preferred. The alkali source described above is particularly preferably used to adjust the pH. Even if volatile alkali, for example in the form of ammonia and/or alkanolamines, which can contain up to 9 carbon atoms in the molecule, can be used to adjust the pH, the alkanolamine here being able to be selected from the group consisting of mono -, Di-, triethanol- and -propanolamine and mixtures thereof, such volatile alkali sources, in particular ethanolamines, are preferably avoided. In various embodiments, agents described herein therefore contain less than 1.75% by weight of alkanolamine, in particular monoethanolamine, and they are very particularly preferably free of it.

To adjust and/or stabilize the pH, an agent can also contain one or more buffer substances (INCI Buffering Agents), usually in amounts of 0.001 to 5% by weight. Buffer substances which are at the same time complexing agents or even chelating agents (chelators, INCI chelating agents) are preferred. Particularly preferred buffer substances are citric acid or citrates, in particular sodium and potassium citrates, for example trisodium citrate·2H ₂ O and tripotassium citrate·H ₂ O.

The cleaning agent can also contain hydrotropes. These are solubilizers. Suitable hydrotropes are, for example, urea, butyl glycol, or aliphatic short-chain anionic or amphoteric solubilizers.

The preparation of the agents described herein can take place in different ways. Forms of supply based on water and/or organic solvents can be thickened, in the form of gels.

In various embodiments, the agent or the respective liquid composition has a viscosity above 200 mPas (Brookfield Viscometer DV-II+Pro, spindle 25, 30 rpm, 20° C.), in particular between 400 and 6000 mPas, directly after production.

According to some embodiments, the cleaning agents described herein are prepackaged to form dosage units. These dosing units preferably include the amount of cleaning-active substances required for one cleaning cycle. Preferred dosage units weigh between 12 and 30 g. The volume of the aforementioned dosing units and their three-dimensional shape can be selected, for example, in such a way that the prefabricated units can be dosed via the dosing chamber of a dishwasher. The volume of the dosage unit is preferably between 10 and 35 ml, preferably between 12 and 30 ml.

The cleaning agents, in particular the prefabricated dosing units, particularly preferably have a water-soluble coating.

The water-soluble cover is preferably formed from a water-soluble film material which is selected from the group consisting of polymers or polymer mixtures. The cover can be formed from one or from two or more layers of the water-soluble film material. The water-soluble film material of the first layer and the further layers, if any, can be the same or different. Films are particularly preferred which can be glued and/or sealed to form packaging such as tubes or pillows after they have been filled with an agent. In various embodiments, the films are in the form of multi-chamber pouches, in which case ingredients of the agent that are not compatible with one another can be spatially separated in different chambers of a pouch made of a water-soluble film.

It is preferred that the water-soluble coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer. Water-soluble coatings that contain polyvinyl alcohol or a polyvinyl alcohol copolymer have good stability with sufficiently high water solubility, especially cold water solubility.

Suitable water-soluble films for producing the water-soluble casing are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range from 10,000 to 1,000,000 gmol ^-1 , preferably from 20,000 to 500,000 gmol ^-1 , particularly preferably from 30,000 to 100,000 gmol ^-1 and in particular from 40,000 to 80,000 gmol ^-1 .

Polyvinyl alcohol is usually produced by hydrolysis of polyvinyl acetate, since the direct synthesis route is not possible. The same applies to polyvinyl alcohol copolymers which are correspondingly produced from polyvinyl acetate copolymers. It is preferred if at least one layer of the water-soluble coating comprises a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.

A polymer selected from the group comprising (meth)acrylic acid-containing (co)polymers, polyacrylamides, oxazoline polymers, polystyrene sulfonates, polyurethanes, polyesters, polyethers, polylactic acid or mixtures of the above polymers can also be added to a polyvinyl alcohol-containing film material suitable for producing the water-soluble covering be. A preferred additional polymer are polylactic acids.

In addition to vinyl alcohol, preferred polyvinyl alcohol copolymers include dicarboxylic acids as further monomers. Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and mixtures thereof, with itaconic acid being preferred.

Polyvinyl alcohol copolymers which are also preferred include, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its ester. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters or mixtures thereof.

It can be preferred that the film material contains further additives. The film material can contain, for example, plasticizers such as dipropylene glycol, ethylene glycol, diethylene glycol, propylene glycol, glycerol, sorbitol, mannitol or mixtures thereof. Further additives include, for example, release aids, fillers, crosslinking agents, surfactants, antioxidants, UV absorbers, anti-blocking agents, anti-adhesive agents or mixtures thereof.

Suitable water-soluble films for use in the water-soluble wrappers of the water-soluble packages of the invention are films sold by MonoSol LLC, for example, under the designation M8630, C8400 or M8900. Other suitable films include films with the designation Solublon® PT, Solublon® GA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or films VF-HP from Kuraray.

The cleaning agents described herein, which are preferably hand dishwashing agents, are characterized by a consumer-appealing milky-white, opaque appearance. The use of ecologically questionable polymer-based opacifiers, such as acrylate-based opacifiers, and mineral opacifiers that are still unstable in storage can be dispensed with. The cleaning agents according to the invention are nevertheless storage-stable, although they contain typical ingredients for hand dishwashing agents, such as anionic surfactants.

The corresponding use of the agents according to the invention is also the subject of the invention, ie in particular the use of an agent as described herein for cleaning and/or disinfecting hard surfaces, in particular for the manual cleaning of dishes.

A further subject matter of the invention is a method for cleaning hard surfaces, which is characterized in that an agent according to the invention is used in at least one method step.

The cleaning agent can be applied undiluted or as an aqueous dilution either directly or using a sponge or brush to the surface to be cleaned and then removed again with water. The cleaning agent according to the present invention is used for cleaning and/or disinfecting surfaces, preferably hard surfaces, in particular dishes and cooking utensils.

All facts, objects and embodiments that are described for the means according to the invention are also applicable to all other aforementioned objects of the invention. Therefore, at this point, reference is expressly made to the disclosure at the appropriate point, with the indication that this disclosure also applies to the above uses and methods according to the invention.

The invention is illustrated below using examples, but is not limited to these.
