Description

COMPOSITIONS FOR FABRIC IMPROVEMENT FIELD OF THE INVENTION The present application relates to fabric care compositions that are added to the rinse comprising one or more entangled and / or grafted polyamines that provide enhanced appearance benefits to the fabrics. The entangled and / or grafted polyamines of the present invention which mitigate the damage to the fabrics and improve the appearance of the fabrics, can be combined with compositions of fabric softening actives that mitigate the damage to the fabrics.

BACKGROUND OF THE INVENTION Domestic fabric treatment is a problem known in the art for the formulator of laundry compositions. Hence, it is well known that alternating cycles of use and washing of fabrics and textiles, such as articles of used clothing and accessories, will inevitably adversely affect the appearance and integrity of the fabric and articles of textile materials used and washed in this way. Fabrics and textiles simply wear out over time and with use. The washing of fabrics and textiles is necessary to eliminate dirt and stains that accumulate in them during normal use. However, the washing operation itself, after many cycles, can accentuate and contribute to the deterioration of the integrity and appearance of said fabrics and textiles. The deterioration of the integrity and appearance of the fabrics can manifest itself in several ways. The short fibers are detached from the structures of the woven / woven fabrics / textiles by the mechanical action of washing. These discharged fibers can form lint, lint or "lint" that are visible on the surface of the fabrics and diminish the appearance of new quality of the fabric. Said fabric abrasion problem is even more acute after multiple washing cycles. There is a great need for compositions that provide protection to fabrics against damage done due to abrasion of fabrics. In addition, there is a great need to provide compositions that provide a remedy for fabric abrasion damage.

Fabric Improvement System The fabric improvement system of the present invention is formed of one or more modified polyamines according to the present invention. The modified polyamines of the present invention comprising the fabric improvement system can be formulated as a mixture in which a proportional amount of two or more compounds is combined to form the fabric improvement system. Alternatively, the formulator can adjust the reaction conditions forming the modified polyamines of the present invention in order to create a mixture of suitable ingredients inter alia a mixture of partially interlaced polyamine fragments and / or modified polyamines. Whether a formulated mixture or a product is used by the procedure, or a mixture or both, the compounds comprising the fabric improvement compositions of the present invention have the formula: i) (PA) w (T) x; I) (PA) W (L) 2; üi) [(PA) w (T)?] and [L] z; wherein PA is a modified or unmodified modified or ungrafted polyamine base structure unit, T is an amide-forming polycarboxylic acid crosslinking unit, and L is an entanglement unit that does not form amide. For compounds of type (i) and (iii), the relative amounts of PA units and T units that are present are such that the molar ratio of PA units to T units is from 0.8: 1 to 1.5: 1. For compounds of type (ii), the relative amounts of PA units and L units that are present are such that (PA) w (L) z comprises about 0.05, preferably about 0.3 to 2 parts by weight of said L. units. Therefore, 1 part of a grafted or ungrafted, modified or unmodified polyamine base structure unit may be combined with from about 0.05, preferably from about 0.3 parts by weight from an L unit to about 2 parts by weight of an L unit to form a suitable modified polyamine compound. Similarly, for compounds of type (ii), interlaced polyamines having the formula (PA) W (T) X can be combined with about 0.05, preferably about 0.3 parts by weight from an L unit to about 2 parts. by weight of an L unit to form a suitable modified polyamine compound having the formula [(PA) w (T) x] and [L] z.

Polyamine base structure (PA units) The modified polyamine compounds of the present invention comprise a polyamine base structure, unit PA, which may be optionally, but preferably, grafted. The following are non-limiting examples of suitable PA units according to the present invention.

Polyalkyleneimine A preferred PA unit according to the present invention consists of polyalkyleneimines and polyalkyleneamines having the general formula: wherein R is linear C 2 -C 2 alkylene, branched C 3 -C 2 alkylene, and mixtures thereof; B represents a continuation of the chain structure by branching. The indices w, x, e and have several values depending on factors such as molecular weight and relative degree of branching. The polyalkyleneimines and polyalkyleneamines comprising PA units of the present invention are divided into three categories based on relative molecular weight. The terms polyalkyleneimine and polyalkyleneamine are used interchangeably throughout the present specification and are taken to mean polyamines having the general formula indicated above regardless of the method of preparation.

Low molecular weight polyalkyleneimines For low molecular weight polyalkyleneimines having the formula: H B [H2N-RuÑ-R]? [N-R] and NH2 R is linear C2-C2 alkylene, branched C3-C2 alkylene, and mixtures thereof; preferably R is ethylene, 1,3-propylene and 1,6-hexylene, more preferably ethylene. The indices w, x, e and are such that the molecular weight of said polyamines does not exceed about 600 daltons. For example, for an entirely linear polyethyleneimine having a molecular weight of about 600 daltons, the index w = 1, x = 13, ey = 0. For a fully branched polyethyleneimine having a molecular weight of about 600 daltons, w = 8 , x = 0 ey = 7. (This combination of indices results in a material having an average molecular weight of about 646 daltons, which, for the purposes of the present invention is a low molecular weight polyalkyleneimine). The index w typically has the value of y + 1. The simplest of the low molecular weight polyamines of this type is ethylene diamine, which may be present up to about 10% by weight of the mixture of PA units. Non-limiting examples of low molecular weight polyalkyleneimine PA units include diethylenetriamine, triethylenetetramine, tetraethylenepentamine, dipropylenetriamine, tripropylenetetramine and dihexamethylenetriamine. The PA units can be used as raw products or mixtures, and if desired by the formulator, these PA units can be used in the presence of small amounts of diamines as described hereinabove, whereby the amount of diamines, inter alia, ethylenediamine , hexamethylenediamine may be present up to about 10% by weight, of the PA unit mixture.

Medium molecular weight scale polyalkyleneimines For medium molecular weight scale polyalkyleneimines having the formula: R is linear C2-C4 alkylene, branched C3-C4 alkylene, and mixtures thereof; preferably R is ethylene, 1,3-propylene, and mixtures thereof, more preferably it is ethylene in which said polyamines are polyethylene imines (PEI's). The indices w, x, e and are such that the molecular weight of said polyamines is from about 600 daltons to about 50,000 daltons. The indices w, x, e y will indicate not only the molecular weight of the polyalkyleneimines but also the degree of branching present in the base structure of the PA unit.

High Molecular Weight Polyalkyleneimines For high molecular weight polyalkyleneimines having the formula: H B [H2N-RyN-R]? [N-R] and NH2 R is linear C2-C3 alkylene, preferably R is ethylene. The indices w, x, e and are such that the molecular weight of said polyamines is from about 50,000 daltons to about 1, 000,000 (1 million) daltons. The indices w, x, e y will indicate not only the molecular weight of the polyalkyleneimines, but also the degree of branching present in the base structure of PA units. Polymeric co-polyamines Another example of a preferred PA unit according to the present invention are polyvinylamine homopolymers or co-polymers having the formula: wherein V is a co-monomer, non-limiting examples of which include vinyl amides, vinyl pyrrolidone, vinyl imidazole, vinyl esters, vinyl alcohols, and mixtures thereof, all of which may be taken together or in combination with polyvinyl amine to form suitable co-polymerization products for use in the fabric improvement systems of the present invention. The m and n indexes are such that the copolymers comprise at least 10%, more preferably at least about 30% units derived from vinyl amine and in which in addition the molecular weight of said copolymers is about 500 daltons, preferably about 5,000 daltons a about 50,000 daltons, preferably at about 20,000 daltons.

Modifications of the polyamine base structure Optionally, but preferably, the PA units of the present invention are modified before or after reaction with an entanglement agent of T units or L units. The two preferred types of modifications are grafting and blocking. Preferably the PA units of the present invention are grafted, ie the PA unit is further reacted with a reagent that elongates said chain of PA units, preferably by reaction of the nitrogens of the PA base structure unit with one or more equivalents of aziridine (ethyleneimine), caprolactam, and mixtures thereof. The grafting units, in contrast to the "blocking" units described hereinafter, may additionally react with themselves to provide chain propagation of PA units. An example of a preferred grafted PA unit of the present invention has the formula: G B [G2N-RyN-R]? [N-R] and NG2 wherein R, B, w, x, e and are the same as defined herein above and G is hydrogen or an extension of the base structure of PA units by grafting. Non-limiting examples of preferred grafting agents are aziridine (ethylenimine), caprolactam, and mixtures thereof. A preferred grafting agent is aziridine in which the base structure is extended by units having the formula: B 'I - [CH2CH2Nr- [CH2CH2N] CH2CH2NH2 wherein B 'is a continuation by branching in which the graft does not exceeds approximately 12 units, preferably -CH2CH2NH2 and the value of the indices p + q has the value of 0, preferably of about 1, more preferably from about 2 to about 7, preferably to about 5. Another preferred grafting unit is caprolactam . The PA units of the present invention can be grafted before or after entanglement with one or more T units that are described here below., preferably the graft is achieved after entanglement with said unit T. This allows the formulator to take advantage of the reactivity differential between the primary and secondary amino units of the base structure of PA units thereby allowing the formulator to link controllably said PA units and that also controls the amount of subsequent branching resulting from the grafting step. Another modification of the optional but preferred PA units is the presence of "blocking" units. For example, a PA unit is reacted with an amount of a monocarboxylic acid, non-limiting examples of which are linear or branched alkyl of CrC22, preferably linear C de or C18 alkyl, inter alia lauric acid, myristic acid. The amount of blocking units that are reacted with the unit PA is an amount that is sufficient to achieve the desired properties of the formula. However, the amount of blocking units used is not sufficient to abate any additional entanglement or grafting that the formulator may choose to carry out.

Interlacing units Amide-forming interlacing units T The interlacing units T are preferably polyamide forming units comprising carbonyl. The T units are taken together with PA units to form interlaced modified polyamine compounds having the formula (PA) w (T) x or [(PA) w (T)?] And [L] z. A preferred embodiment of the present invention includes interlaced PA units in which a unit T provides interlacing between two or more PA units to form an interlaced section of (PA) W (T) X polyamide. A preferred interlacing unit T has the general formula: O O II 1 9 I '- C- (R2) - (R1) k- (R2) -C- wherein R 1 is methylene, phenylene, and mixtures thereof; preferably methylene. The index k has the value of 2 to about 8, preferably to about 4. The preferred values of k are 2, 3, and 4. R2 is -NH-, thereby forming a urethane amide bond, when said R2 is comprises units T reacts with the nitrogens of the base structure of the PA units. The value of the index j is independently 0 or 1. The presence of units R2 may result, for example, from the use of diisocyanates as crosslinking agents. Non-limiting examples of dibasic acids which are used as a source of T units in the above formula include succinic acid, maleic acid, adipic acid, glutaric acid, suberic acid, sebacic acid and terephthalic acid. However, the formulator is not limited to T interlacing units that are derived from dibasic acids; for example, tribasic interlacing T units, inter alia, citrate, can be used to link the PA units of the present invention. Examples of compounds of (PA) w (T) x according to the present invention are obtained by condensation of dicarboxylic acids, interalia, succinic acid, maleic acid, adipic acid, terephthalic acid, with polyalkylene polyamines, inter alia, diethylenetriamine, triethylenetetramine, dipropylenetriamine, tripropylenetetramine in which the ratio of the dicarboxylic acid to polyalkyleneamine is from 1: 0.8 to 1: 1.5 moles, preferably a ratio of 1: 0.9 to 1: 1.2 moles in which the resulting interlaced material has a viscosity in an aqueous solution 50% by weight, more than 100 centipoise at 25 ° C.

The L units of the present invention are any unit that suitably interlaces PA units or units (PA) w (T) x Preferred L-link units comprise units that are derived from the use of epihalohydrins, preferably epichlorohydrin, as an entanglement agent Epihalohydrins can be used directly with the PA units or can be suitably combined with other entanglement-bound ingredients non-limiting examples of the which include alkylene glycols and polyalkylene polyglycols inter alia ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, diprop ilenglycol, polypropylene glycol, butylene glycol, hexanediol-1,6-glycerol, oligoglycerol, pentaerythritols, polyols that are obtained by the reduction of carbohydrates (sorbitol, mannitol), monosaccharides, disaccharides, oligosaccharides, polysaccharides, polyvinyl alcohols, and mixtures thereof. For example, a suitable unit L is a dodecylene unit having the formula: - (CH 2) 2 - in which an equivalent of 1,22-dichlorodiodecan is reacted, for example, with an appropriate amount of a PA unit for produce a polyamine which is entangled by dodocylene units. For the purposes of the present invention, the interlacing L units comprising only carbon and hydrogen are considered to be "hydrocarbyl" L units. Preferred hydrocarbyl units are polyalkylene units having the formula: - (CH2) n-in which n is from 1 to about 50. The hydrocarbyl units L can be derived from hydrocarbons having two units that are capable of reacting with the nitrogen of the PA units. Non-limiting examples of precursors that result in the formation of hydrocarbyl L units include 1,6-dibromohexane, 1,8-ditosiloctane, and 1,14-dichlorotetradecane. Additional examples of preferred non-amidating interlacing units L are units that are derived from entanglement units in which epihalohydrin is used as the connection unit. For example, 1,2-dihydroxydodecane is reacted with epichlorohydrin to form the bis-epoxide precursor of the non-amide unit L having the formula: r >; - CHgO- (CH2) 12- (Hg- < 1 which when reacted with one or more units PA or units (PA) W (T) X results in an L unit of interlacing having the formula: however, it is not necessary to preform and isolate the bis-epoxide, rather the precursor of the entanglement unit can be formed in situ by reaction of 1,12-dihydroxydedecane or another suitable precursor unit with epihaiohydrin in the presence of units (PA) W (T) X or PA units grafted or not grafted.

Other L units of interlacing using one or more Epihaiohydrin connection units include polyalkylenoxy L units having the formula: wherein R1 is ethylene, R2 is 1.2-propylene, x is from 0 to 100 e and is from 0 to 100.

Another preferred unit which may comprise an L unit and which can be suitably combined with epihaiohydrin connection units, includes polyhydroxy units having the formula: wherein the index t is from at least 2 to about 20 and the index u is from 1 to about 6. The formulator may also combine units to form hybrid interlacing units L, for example, units that They have the formula: OH CH- CH-CH2- -0 (CH2) t (CH) uO- -0 (R10)? (R20) v "C H2 CHCH OH iw OH in which the wey indices are each independently from 1 to 50, z They are units that are present in an amount sufficient to properly connect the polyhydroxy units and the polyalkylenoxy units in the base structure without the formation of ether bonds. The following is an example of a linking group L comprising a polyalkylenoxy unit and a polyhydroxy unit: OH CHgOH - CH2CHCH2 - OCHgCHCHCHCHO - CH2CHCH2 - O (CH2CH2?) 4- CH2CHCH2 - OH OH OH OH A further example of preferred interlacing units L are units comprising at least two aziridine groups as connection groups, for example an unit L having the formula: O O r \ II II / i N-CH2CH2- NH-C- (CHg) ^ - C- NH- CH ^ CHj- J which can be used to link two units (PA) w, two units (PA) w (T) t, or mixtures thereof.

The abrasion reduction polymers of fabrics useful in the present invention have the formula: [-P (D) m-] n in which the unit P is a polymer base structure comprising units that are homopolymeric or copolymeric. The units D are defined hereinafter. For the purposes of the present invention the term "homopolymeric" is defined as "a polymer base structure which is composed of units having the same unit composition, ie, formed from polymerization of the same monomer". For the purposes of the present invention the term "copolymeric" is defined as "a polymer base structure which is constituted of units having a different unit composition, ie, formed from the polymerization of two or more monomers.

The base structures of the fabric abrasion reduction polymers of the present invention comprise one or more D units which are units comprising one or more units that provide a dye transfer inhibition benefit. Unit D can be part of the base structure itself as represented in the general formula: [-P (D) m "] Po unit D can be incorporated into the base structure as a pending group to a unit of base structure that has, for example, the formula: - [CR-CFy- - [(CR)? - L] - D D However, the number of D units depends on the formulation. For example, the number of D units will be adjusted to provide polymer water solubility as well as dye transfer inhibition efficiency while providing a polymer that has fabric abrasion reduction properties. The molecular weight of the fabric abrasion reduction polymers of the present invention is about 500, preferably about 1000, more preferably about 100,000, more preferably about 160.00 to about 6,000,000, preferably about 2,000,000, more preferably to about 1, 000,000, still more preferably to about 500,000, more preferably to about 360,000 daltons.

Polymers comprising amide units Non-limiting examples of preferred D units are units D comprising an amide moiety. Examples of polymers in which an amide unit is introduced into the polymer through a pending group include polyvinyl pyrrolidone having the formula: polyvinyloxazolidone having the formula: polyvinylmethyloxazolidone having the formula: N-substituted polyacrylamides and polyacrylamides having the formula: wherein each R 'is independently hydrogen, C 1 -C 2 alkyl, or both R' units can be taken together to form a ring comprising 4-6 carbon atoms; N-substituted polymethacrylamides and polymethacrylamides having the general formula: wherein R 'is independently hydrogen, C-Cß alkyl, or both R' units can be taken together to form a ring comprising 4-6 carbon atoms; poly (N-acrylglycinamide) having the formula: wherein each R 'is independently hydrogen, C 1 -C 2 alkyl, or both R' units can be taken together to form a ring containing from 4 to 6 carbon atoms; poly (N-methacrylylglycinamide) having the formula: wherein each R 'is independently hydrogen, C 1 -C 2 alkyl, or both R' units can be taken together to form a ring having 4 to 6 carbon atoms; polyvinyl urethanes having the formula: - [CH-CH2] n- O I C = 0 N (R ') 2 in which each R' is independently hydrogen, C 1 -C 2 alkyl, or both R 'units can be taken together to form a ring containing 4-6 carbon atoms. An example of a unit D in which the nitrogen of the dye transfer inhibition portion is incorporated into the base structure of the polymer is a poly (2-ethyl-2-oxazoline) having the formula: in which the index n indicates the number of monomer residues present. The fabric abrasion reduction polymers of the present invention may comprise any mixture of dye transfer inhibition units that provide the product with suitable properties. Preferred polymers comprising units D which are amine moieties are those having the nitrogen atoms of the amide unit highly substituted so that the nitrogen atoms are in effect protected to a variable degree by the surrounding non-polar groups. This provides the polymers with an amphiphilic character. Non-limiting examples include polyvinyl pyrrolidones, polyvinyloxazolidones, N, N-disubstituted polyacrylamides, N, N-disubstituted polymethacrylamides. A detailed description of the physicochemical properties of some of these polymers is given in "Water-Soluble Synthetic Polymers: Properties and Behavior," Philip Molyneux, Vol. I, CRC Press, (1983) included herein by reference. The amide-containing polymers can be present in partially hydrolyzed and / or interlaced forms. A preferred polymeric compound for the present invention is polyvinylpyrrolidone (PVP). This polymer has an amphiphilic character with a highly polar amide group that gives it hydrophilic and polar attractant properties, and also has non-polar methylene and methine groups, in the base structure and / or the ring, which give it hydrophobic properties. The rings can also provide flat alignment with the aromatic rings in the dye molecules. PVP is easily soluble in aqueous and organic solvent systems. The PPV is available ex ISP, Wayne, New Jersey, and BASF Corp. Parsippany, New Jersey, as a powder or in aqueous solutions in various viscosity grades, designated as K-12, K-15, K-25 and K- 30 These K values indicate the viscosity average molecular weight, as shown below: PVP K-12, K-15 and K-30 is also available ex Polysciences, Inc. Warrington, Pennsylvania, PVP K-15, K-25 and K-30 and poly (2-ethyl-2-oxazoline) are available ex Aldrich Chemical Co., Inc.

Even the PVP type material suitable for use in the present invention is polyvinylpyrrolidone-co-dimethylaminoethyl methacrylate, commercially available ex ISP in a quaternized form under the tradename Gafquat® or commercially available ex Aldrich Chemical Co. with a molecular weight of about 1.0. MM; polyvinylpyrrolidone-venyl co-acetate, available ex BASF under the trade name Luviskol®, available in ratios of vinylpyrrolidone: vinyl acetate from 3: 7 to 7: 3.

Polymers Containing N-Oxide Units Another D unit that provides improved dye transfer inhibition to the abrasion reduction polymers of fabrics described herein, are N-oxide units having the formula: wherein R1, R2 and R3 can be any hydrocarbyl unit (for the purposes of the present invention the term "hydrocarbyl" does not include the hydrogen atom only). The N-oxide unit can be part of a polymer, such as a polyamine, ie a polyalkyleneamine base structure, or the N-oxide can be part of a pendant group attached to the base structure of the polymer. An example of a polymer comprising an N-oxide unit as part of the base structure of the polymer is polyethyleneimine N-oxide. Non-limiting examples of groups which may comprise an N-oxide moiety include the N-oxides of some heterocycles including pyridine, pyrrole, imidazole, pyrazole, pyrazine, pyrimidine, pyridazine, piperidine, pyrrolidine, pyrrolidone, azolidine, morpholine. A preferred polymer is poly (4-vinylpyridine N-oxide, PVNO). In addition, the N-oxide unit may be pendent to the ring, for example, aniline oxide. The N-oxide containing polymers of the present invention will preferably have a ratio of N-oxidized amine nitrogen to non-oxidized amine nitrogen of from about 1: 0 to about 1: 2, preferably to about 1: 1, more preferably to about 3: 1 The formulator can adjust the amount of N-oxide units. For example, the formulator can copolymerize monomers containing N-oxides with monomers that do not contain N-oxides to reach the desired ratio of N-oxide amino units to non-N-oxidized amino units, or the formulator can control the level of oxidation of the polymer during the preparation. The amine oxide unit of the polyamine N-oxides of the present invention has a Pka less than or equal to 10, preferably less than or equal to 7, more preferably less than or equal to 6. The average molecular weight of the Polymers containing N-oxides that provide a dye transfer inhibiting benefit to reduced fabric abrasion polymers is about 500 daltons, preferably about 100,000 daltons, more preferably from about 160,000 daltons to about 6,000,000 daltons, preferably at about 2,000,000 daltons, more preferably at approximately 360,000 daltons.

Polymers comprising amide units and N-oxide units A further example of polymers that are fabric abrasion reduction polymers having dye transfer inhibition benefits are polymers comprising amide units and N-oxide units as described above in the I presented. Non-limiting examples include copolymers of two monomers in which the first monomer comprises an amide unit and the second monomer comprises an N-oxide unit. In addition, the oligomers or block polymers comprising these units can be taken together to form mixed amide / N-oxide polymers. However, the resulting polymers should retain the water solubility requirements described hereinabove.

Molecular Weight For all fabric abrasion reduction polymers of the invention described above, it is more preferred that they have a molecular weight on the scale as described hereinabove. This scale is typically higher than the scale for polymers that provide only benefits of inhibition of dye transfer alone. Indeed, the higher molecular weight of the abrasion reduction polymers provides reduction of fabric abrasion which typically occurs after the treatment, for example during the use of the garment, especially in a subsequent washing process. Without being limited by theory, it is believed that the high molecular weight allows deposition of the polymer on the surface of the fabric and provides sufficient substantivity so that the polymer can remain on the fabric during subsequent use and subsequent washing of the fabric. Furthermore, it is believed that for a given charge density, increasing the molecular weight will increase the substantivity of the polymer to the surface of the fabric. Ideally, the charge density and molecular weight balance will provide a sufficient rate of deposition on the surface of the fabric and sufficient attraction to the fabric during subsequent wash cycles. It is considered preferable to increase the molecular weight instead of increasing the charge density since this allows a larger selection in the range of materials that can provide the desired benefit and avoids the negative impact that increasing the charge density can have inter alia the attraction of dirt and debris on the treated fabrics. It should be mentioned, however, that a similar benefit can be predicted from the method of increasing the charge density while retaining a lower molecular weight material.

Dye Binding Agents The compositions of the present invention optionally comprise from about 0.001%, preferably from about 0.5% to about 90%, preferably to about 50% by weight, more preferably to about 10%, more preferably to about 5% by weight, of one or more colorant fixing agents. Dye fixative agents, or "fixatives," are well known and commercially available materials that are designed to improve the appearance of dyed fabrics by reducing the loss of dye from fabrics caused by washing. Within this definition, the components that in some modalities can function as fabric softening active are not included. Many dye binding agents are cationic, and are based on quaternized nitrogen compound or nitrogen compounds having a strong cationic charge which is formed in situ under the conditions of use. Cationic fixatives are available under various trade names from various suppliers. Representative examples include: CROSCOLOR PMF (July 1981, Code No. 7894) and CROSCOLOR NOFF (January 1988, Code No. 8544) ex Crosfield; INDOSOL E-50 (February 27, 1984, Ref.

A preferred dye fixing agent for use in Is compositions of the present invention is CARTAFIX CB® ex Clariant. Other cationic dye binding agents are described in "Aftertreatments for improving the fastness of dyes on textile fibers" Cristopher C. Cook, Rev. Prog. Coloration Vol. XII, (1982). Suitable dye binding agents to be used in the present invention are ammonium compounds such as fatty acid diamine condensates, inter alia the hydrochloride, acetate, methosulfate and benzyl hydrochloride salts of diamine esters.

The compositions of the present invention optionally comprise from about 0.01%, preferably from about 0.05%, more preferred from about 0.5% to about 50%, preferably up to about 25%, most preferred to about 10% by weight, even more preferred to about 5% by weight of one or more cellulose reactive dye binding agents. The cellulose reactive dye binding agents can be combined in an appropriate manner with one or more dye fixatives described hereinbefore in order to constitute a "dye binding system". The term "cellulose reactive dye binding agent" is defined herein as "a dye fixing agent that reacts with cellulose fibers after heat application or after heat treatment either in situ or by the formulator. " Cellulose reactive fixing agents suitable for use in the present invention can be defined by the following test procedure.

Cellulose Reactivity Test (CRT) Four pieces of fabric are selected that can exude their dye (for example, 10 x 10 cm of cotton fabric dyed with Direct Red 80). Two fabric trimmings are used as a first control and a second control, respectively. The remaining two cuttings are rinsed for 20 minutes in an aqueous solution containing 1% (w / w) of the cellulose reactive dye binding agent to be tested. The cuts are removed and dried completely. One of the treated cuts that has been completely dried is passed ten times through an ironing iron that adjusts to a temperature for "linen cloth". The first control cut is also passed ten times through an ironing iron that adjusts to the same temperature. All four cut-outs (the two control cut-outs and the two treated cut-outs, each of which has been treated with the ironer for ironing) are washed separately in Launder-O-Meter containers under typical conditions with a commercial detergent used at the recommended dosage for half an hour at 60 ° C, followed by a full rinse of 4 times in 200 ml of cold water and then dried on a drying rack. Then, the firmness of the color is measured by comparing the DE values of a new cut without treating with the cuttings that have been subjected to the test. The DE values, the calculated color differences, are defined in ASTM D2244. In general, the DE values refer to the magnitude and direction of the difference between two psychophysical color stimuli defined by tristimulus values, or by chromaticity coordinates and luminance factor, calculated by means of a specific group of equations for difference of color defined in the CIEL 1976 CIELAB opponent color space, Hunter's opponent color space, Friele-Mac Adam-Chickering color space, or any equivalent color space. For the purposes of the present invention, the lower the DE value for a sample, the closer the sample will be to the untreated sample and the greater the color firmness benefit. Because the test relates to the selection of a cellulose-reactive dye fixing agent, if the DE value for the sample treated in the ironing step has a value that is better than that of the two control samples, then the candidate is a cellulose reactive dye binding agent useful for the purposes of the invention. Typically cellulose reactive dye binding agents are compounds that contain a reactive portion to cellulose, non-limiting examples of these compounds include halogen triazines, vinylsulfones, epichlorohydrin derivatives, hydroxyethylene urea derivatives, formaldehyde condensation products, polycarboxylates, glyoxal and glutaraldehyde derivatives, and mixtures thereof. Additional examples can be found in "Textile Processing and Properties", Tyrone L. Vigo, on pages 120 to 121, Elsevier (1997) describing specific electrophysical groups and their corresponding affinity for cellulose. Preferred hydroxyethyleneurea derivatives include dimethyloldihydroxyethylene, urea and dimethyl urea glyoxal. Preferred formaldehyde condensation products include the condensation products derived from formaldehyde and a group selected from an amino group, an imino group, a phenol group, a urea group, a cyanamide group and an aromatic group. The commercially available compounds of this class are Sandofix WE 56 from Ciariant, Zetex E from Zeneca and Levogen BF from Bayer. Preferred polycarboxylate derivatives include tetracarboxylic butane acid derivatives, citric acid derivatives, polyacrylates, and derivatives thereof. A most preferred reactive cellulose dye fixing agent is one of the class of hydroxyethyleneurea derivatives marketed under the trade name Indosol CR from Ciariant. Even other more preferred cellulose reactive binding agents are marketed under the tradename of Rewin DWR and Rewin WBS of CHT R. Beitlich.

The following "crystal growth inhibition test" is used to determine the suitability of a material to be used as a crystal growth inhibitor.

Crystal growth inhibition test (CGIT) The suitability of a material to serve as a crystal growth inhibitor according to the present invention can be determined by evaluating in vitro the growth rate of certain organic microcrystals.

The procedure of Nancollas et al., Described in "Calcium Phosphate Nucleation and Growth in Solution", Prog. Crystal Growth Charact., Vol. 3, 77-102, (1980), incorporated herein by reference, is an appropriate method for evaluating compounds for their ability to inhibit crystal growth. The graph shown in Figure 1 exemplifies a curve indicating the delay in time (t-lag) in the crystal formation provided by a hypothetical crystal growth inhibitor. The observed t-lag provides a measure of the ctiveness of the compound with respect to retarding the growth of calcium phosphate crystal. The higher the t-lag, the more cient the crystal growth inhibitor will be.

Illustrative procedure Combine in an appropriate container: 2.1M KCl (35 mL), 50 mL of 0.0175M CaCl2, 50 mL of 0.01M KH2PO4, and 350 mL of deionized water. A standard pH electrode equipped with a standard Calomel reference electrode is inserted and the temperature is adjusted to 37 ° C while purging oxygen from the solution. Once the temperature and pH are stabilized, a solution of the crystal growth inhibitor to be evaluated is added. A typical inhibitor test concentration is 1 x 10"6 M. The solution is titrated to pH 7.4 with 0.05 M KOH. The mixture is then treated with 5 ml of a hydroxyapatite suspension.The hydroxyapatite suspension can be prepared by digesting powder Hydroxyapatite Bio-Gel® HTP (100 g) in 1 liter of distilled water whose pH is adjusted to 2.5 by adding enough 6N HCl and heating the solution until all the hydroxyapatite is dissolved (it may be necessary to heat for several days). the temperature of the solution is maintained at approximately 22 ° C while the pH is adjusted to 12 by adding a 50% aqueous solution of KOH Again the solution is heated and the resulting suspension is allowed to stand for 2 days before the solution is removed. Supernatant: 1.5 liters of distilled water are added, the solution is stirred, then it is left to rest again for 2 days and the supernatant is removed. This rinsing procedure is repeated six more times after which the pH of the solution is adjusted to neutral using 2N HCl. The resulting suspension can be stored at 37 ° C for 11 months. Crystal growth inhibitors that are suitable for use in the present invention have a t-lag of at least 10 minutes, preferably at least 20 minutes, more preferably at least 50 minutes at a concentration of 1 x 10"6M. Crystal growth inhibitors differ from chelating agents by the fact that crystal growth inhibitors have a low binding affinity of heavy metal ions, ie copper, for example, crystal growth inhibitors have an affinity for copper ions in a 0.1% ionic strength solution when measured at 25 ° C, less than 15, preferably less than 12. The preferred crystal growth inhibitors of the present invention are selected from the group consisting of of carboxylic compounds, organic diphosphonic acids and mixtures thereof The following are non-limiting examples of preferred crystal growth inhibitors.

The anion can also carry, but less preferably, a double charge, in which case X? represents half of a group. The index m has a value of 1 to 3; the index n has a value of 1 to 4, preferably 2 or 3, more preferred 2. One embodiment of the present invention provides quaternized amines and amines having two or more different values for the n-per-molecule index, for example, an agent active softener prepared from the starting metal methyl (3-aminopropyl) (2-hydroxyethyl) amine. The most preferred softening actives according to the present invention have the formula: in which the unit that has the formula: It is a fatty acyl portion. Fatty acyl portions suitable for use in the softening actives of the present invention are derived from triglyceride sources including tallow, vegetable oils and / or partially hydrogenated vegetable oils including, among others, canola oil, safflower oil, peanut oil, sunflower oil, corn oil, soybean oil, wood oil and rice bran oil. Even more preferred are quaternary ammonium diester compounds (DEQA's) in which the m-index is equal to 2. The formulator, depending on the desired physical and performance properties of the final fabric softening active, can select from any of the sources of fatty acyl portions mentioned above, or alternatively, the formulator can mix the triglyceride sources to form a "custom blend". However, those skilled in the art of fats and oils will recognize that the fatty acyl composition may vary, as in the case of vegetable oil, from harvest to harvest, or from a variety of vegetable oil source to another variety of source. vegetable oil. DEQAs that are prepared using fatty acids derived from natural sources are preferred. A preferred embodiment of the invention provides softening actives comprising R1 units having at least about 3%, preferably about 5%, more preferably about 10%, more preferably about 15% of C alkenyl. C22, including polyalkenyl (polyunsaturated) units among others oleic, linoleic, linolenic. For the purposes of the present invention the term "mixed chain fatty acyl units" is defined as "a mixture of fatty acyl units comprising alkyl and alkenyl chains having from 10 to 22 carbon atoms including the carbonyl carbon atom, and in the case of the alkenyl chains, from one to three double bonds, preferably all double bonds in the cis configuration. "With respect to the R1 units of the present invention, it is preferred that at least a substantial percentage of the groups fatty acyl are unsaturated, for example, of about 25%, preferably from about 50% to about 70%, preferably about 65% The total level of fabric softening active containing polyunsaturated fatty acyl groups can be about 3%, preferably about 5%, more preferably about 10% to about 30%, preferably about 25%, more preferably about 18% As indicated hereinabove, the cis and trans isomers can be used, preferably with a cis / trans ratio of 1: 1, preferably at least 3: 1, and more preferably from about 4: 1 to about 50: 1, m s preferably from about 20: 1, however, the minimum is 1: 1. The level of unsaturation contained within tallow, barley or other fatty acyl unit chain can be measured by the iodine value (IV) of the corresponding fatty acid, which in the present case should preferably be in the range of 5 to 100 distinguishing two categories of compounds, which have an IV below or above 25. In fact, for compounds that have the formula: (R); -m - derivatives of tallow fatty acids, when the iodine value is from 5 to 25, preferably 15 to 20, it has been found that the larger cis / trans isomer weight ratio of about 30/70, preferably more large of approximately 50/50 and more preferably larger of approximately 70/30 provides optimum concentration capacity. For compounds of this type made from tallow fatty acids having an iodine value greater than 25, it has been found that the ratio of the cis to trans isomers is less critical unless high concentrations are required. Another preferred embodiment of the present invention comprises DEQAs, in which the average iodine value for R1 is about 45. The R1 units suitable for use in the isotropic liquids of the present invention can be further characterized by the iodine value ( IV) of the original fatty acid, said IV preferably being about 10, more preferably about 50, more preferably about 70, to a value of about 140, preferably about 130, more preferably about 115. However, the formulators , depending on which embodiment of the present invention they choose to execute, they may wish to add a number of fatty acyl units having iodide values outside the scale listed hereinabove. For example, the "hardened supply material" (IV less than or equal to about 10) can be combined with the source of the fatty acid mixture to adjust the properties of the final softening active. A preferred source of fatty acyl units, especially fatty acyl units having branching, for example, "Guerbet branching", methyl, ethyl units, etc; substituted with the primary alkyl chain, synthetic sources of fatty acyl units are also suitable. For example, the formulator may wish to add one or more fatty acyl units having a methyl branch in a "non-naturally occurring" position, for example, in the third carbon of a C-? 7 chain. What is meant in the present with the term "that does not occur naturally" is that "acyl units that are not found in significant quantities (greater than approximately 0.1%) are common fats and oils that serve as supply materials for the source of triglycerides described herein. " If the desired branched chain fatty acyl unit can not be obtained from readily available natural supply materials, then, the synthetic fatty acid can be suitably mixed with other synthetic materials, or with other sources derived from natural triglyceride of acyl units. The following are examples of preferred softening active agents according to the present invention: N, N-di (tallowyloxyethyl) -N, N-dimethylammonium chloride; N, N-di (canolyl-oxy-ethyl) -N, N-dimethylammonium chloride; N, N-di (tallowyloxyethyl) -N-methyl, N- (2-hydroxyethyl) ammonium chloride; N, N-di (canolyl-oxy-ethyl) -N-methyl, N- (2-hydroxyethyl) ammonium chloride; N, N-di (2-tallowoyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N-di (2-canolyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N-di (2-tallowyloxyethylcarbonyloxyethyl) -N, N-dimethyl-ammonium chloride; N, N-di (2-canolyloxyethylcarbonyloxyethyl) -N, N-dimethyl-ammonium chloride; N- (2-tallowoyloxy-2-ethyl) -N- (2-tallowoyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N- (2-canolyloxy-2-ethyl) -N- (2-canolyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N, N-tri (tallowyl-oxy-ethyl) -N-methylammonium chloride; N, N, N-tri (canolyl-oxy-ethyl) -N-methylammonium chloride; N- (2-tallowoyloxy-2-oxoethyl) -N- (tallowyl) -N, N-dimethyl-ammonium chloride; N- (2-canolyloxy-2-oxoethyl) -N- (canolyl) -N, N-dimethyl-ammonium chloride; Chloride of 1,2-diploboyloxy-3-N, N, N-trimethylammoniopropane; Chloride of 1, 2-dicanolilox¡-3-N, N, N-trimethylammoniopropane, and mixtures of the above assets.

Main Solvent The compositions of the present invention, preferably the isotropic liquid modalities thereof, may also optionally comprise a principal solvent. The level of main solvent present in the compositions of the present invention is typically less than about 95%, preferably less than about 50%, more preferably less than about 25%, more preferably less than about 15% by weight. Some embodiments of the isotropic liquid embodiments of the present invention may not comprise a principal solvent but may be substituted by an appropriate nonionic surfactant. The main solvents of the present invention are used primarily to obtain liquid compositions having sufficient clarity and viscosity. The major solvents must also be selected to minimize the impact of solvent odor in the composition. For example, isopropyl alcohol is not an effective principal solvent because it does not serve to produce a composition having adequate viscosity. Norpropanol does not serve as an adequate principal solvent because it has a relatively strong aroma. The major solvents are also selected for their ability to provide stable compositions at low temperatures, preferably the compositions comprising suitable principal solvents are decreased to approximately 4 ° C and have the ability to completely recover their clarity if stored as low as 7 ° C. ° C. The major solvents according to the present invention are selected based on their octanol / water partition coefficient (P). The octanol / water partition coefficient is a measure of the ratio of the concentrations of a particular principal solvent in octanol and water in equilibrium. The division coefficients are expressed and reported conveniently as their logarithm to base 10; logP. The logP of many species of principal solvent has been reported; for example, the Ponmona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), contains many, along with references to the original literature. However, the logP values are more conveniently calculated using the "CLOGP" program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database. The "calculated logP" (ClogP) is determined by the fragment method of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, vol.4, C. Hasch, PG Sammens, JB Taylor and CA Ransden, Eds ., pp. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment method is based on the chemical structure of each species HR, and takes into account the numbers and types of atoms, the atom's connectivity, and the chemical bond. The ClogP values are the most reliable and widely used estimates for octanol / water division. It should be understood by those skilled in the art that experimental log P values can also be used. The experimental log P values represent a less preferred embodiment of the invention. When experimental log P values are used, log P values of one hour are preferred. Other methods that can be used to compute ClogP include, for example, the Crippen fragmentation method as described in J. Chem. Inf. Comput. Sci., 27a, 21 (1987); the method of Viswanadhan fragmentation as described in J. Chem. Inf. Comput. Sci., 29, 163 (1989); and the Broto method as described in Eur. J. Med. Chem.-Chim.Theor., 19, 71 (1984). The major solvents suitable for use in the present invention are selected from those having a ClogP of from about 0.15 to about 1, preferably from about 0.15 to about 0.64, more preferably from about 0.25 to about 0.62, still more preferably from about 0.4 to about 0.6. Preferably, the main solvent is at least to some degree an asymmetric molecule, preferably having a melting point, or solidification point which allows the main solvent to be liquid at or near room temperature. Low molecular weight major solvents may be desirable for some embodiments. The most preferred molecules are highly asymmetric.

Hydrophobic Dispersant A preferred composition of the present invention comprises from about 0.1%, preferably from about 5%, more preferably from about 10% to about 80%, preferably to about 50%, more preferably to about 25% by weight, of a Hydrophobic polyamine dispersant having the formula: wherein R, R1 and B are suitably described in the U.S.A. do not. 5,565,145 Watson et al., Issued October 15, 1996, incorporated herein by reference, and w, x, e, and have values that provide a base structure before replacement of preferably at least 1200 daltons, more preferably 1800 daltons . The R1 units are preferably alkyleneoxy units having the formula: - (CH2CHRO) m (CH2CH2O) nH in which R 'is methyl or ethyl, m and n are preferably from about 0 to about 50, with the proviso that the average value of alkoxylation provided by m + n is at least about 0.5. A further description of suitable dispersants for use in the present invention is found in the U.S.A. No. 4,891, 160 Vander Meer, issued on January 2, 1990; E.U.A. No. 4,597,898, Vander Meer, issued July 1, 1986; European patent application 111, 965, Oh and Gosselink, published June 27, 1984; European patent application 111, 984, Gosselink, published June 27, 1984; European patent application 112,592, Gosselink, published July 4, 1984; patent of E.U.A. No. 4,548,744, Connor, issued October 22, 1985; and patent of E.U.A. No. 5,565,145 Watson et al., Issued October 15, 1996; all of which are included herein by reference. However, any clay / dirt or anti-redeposition dispersing agent can be used in the laundry compositions of the present invention.

Electrolyte The fabric softener embodiments of the compositions of the present invention, especially the transparent, isotropic liquid fabric softening compositions, may also optionally, but preferably, contain one or more electrolytes for the control of phase stability, viscosity and / or clarity. For example, the presence of certain electrolytes, inter alia calcium chloride, magnesium chloride, may be key to ensuring the clarity and low viscosity of the initial product, or may affect the dilution viscosity of the liquid modalities, especially liquid isotropic modalities. Without wishing to be limited by theory, but only wanting to provide an example of a situation in which the formulator must ensure the proper dilution viscosity, the following example is included. Fabric, liquid, isotropic or non-isotropic fabric softening compositions can be introduced into the rinse phase of the washing operations by a manufacturing article designed to deliver a measured amount of said composition. Typically, the article of manufacture is a dispenser that supplies the softening active only during the rinse cycle. These dispensers are typically designed to allow a quantity of water equal to the volume of the softening composition to enter the dispenser to ensure a complete supply of the softening composition. An electrolyte can be added to the compositions of the present invention to ensure phase stability and prevent the diluted softener composition from "gelling" or suffering from an undesirable or unacceptable viscosity increase. Preventing the gelling or the formation of a "swollen" solution, of high viscosity is ensured by means of the supply of the softening composition. However, those skilled in the art of fabric softening compositions will recognize that the electrolyte level is also influenced by other factors, inter alia the type of the fabric softening active, the amount of the main solvent, and the level and type of nonionic surfactant. For example, triethanolamine derived from ester quaternary amines suitable for use as softening actives in accordance with the present invention are typically made so as to produce a distribution of mono-, di-, and tri-esterified quaternary ammonium compounds and amine precursors. . Therefore, as in this example, the variability in the distribution of mono-, di- and tri-esters and amines may indicate a different level of electrolyte. Therefore, the formulator should consider all the ingredients, namely, active softener, non-ionic surfactant, and in the case of sotropic liquids, the type and level of the main solvent, as well as the level and identity of the adjunct ingredients before selecting the type and / or level of electrolyte. A wide variety of ionizable salts can be used. Examples of suitable salts are the halides of the metals of group IA and HA of the Periodic Table of the elements, for example, calcium chloride, sodium chloride, potassium bromide and lithium chloride. Ionizable salts are particularly useful during the process of mixing the ingredients to make the compositions herein, and subsequently to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted according to the wishes of the formulator. Typical levels of salts used to control the viscosity of the composition are from about 20 to about 10,000 parts per million (ppm), preferably from about 20 to about 5,000 ppm, of the composition. Alkylene polyammonium salts can be incorporated into the compositions to give viscosity control in addition to or in place of the water-soluble, water-soluble salts above. In addition, these agents can act as scavengers, forming ion pairs with anionic detergent transported from the main wash, in the rinse, and on the fabrics, and can improve the yield of softness. These agents can stabilize the viscosity on a broader scale of temperature, especially at low temperatures, compared to inorganic electrolytes. Specific examples of alkylenepolyammonium salts include L-lysine, monohydrochloride and 1,5-diammonium 2-methylpentane dihydrochloride.

Cationic charge enhancers The compositions of the present invention may optionally contain one or more cationic charge enhancers, especially to the fabric softening modalities that are added in the rinse of the cationic charge. present invention. Typically, ethanol is used to prepare many of the ingredients listed below and is therefore a source of solvent in the final product formulation. The formulator is not limited to ethanol, but can instead add other solvents inter alia hexylene glycol to help in the formulation of the final composition. This is especially true in clear isotropic compositions, translucent. Preferred cationic charge increasers of the present invention are described hereinafter. i) Quaternary ammonium compounds An optional composition of the present invention comprises at least about 0.2%, preferably from about 0.2% to about 10%, more preferably from about 0.2% to about 5% by weight, of a charge enhancer cationic that has the formula: R2 R1- N + - R3 X " wherein R1, R2, R3, and R4 are each independently C-C22-alkyl, C3-C22-alkenyl, R5-Q- (CH2) m-, wherein R5 is C-C22 alkyl, and mixtures of the same, m is from 1 to about 6; X is an anion.

Suitable polyvinylamines for use in the present invention are available from BASF. Optionally, one or more hydrogens of the unit -NH2 of the base structure of the polyvinylamines can be replaced by an alkyleneoxy unit having the formula: - (R10) R2 wherein R is C2-C4 alkylene, R2 is hydrogen, C4 alkyl, and mixtures thereof; x is from 1 to 50.

Substitutions like the previous ones are represented by the abbreviated formula PO-EO? -. Nevertheless, more than one propyleneoxy unit can be incorporated in the alkylenoxy substituent. The polyvinylamines are especially preferred for use as a cationic charge intensifier in liquid fabric softening compositions since a greater number of amine portions per unit of weight provides substantial charge density. In addition, the cationic charge is generated in situ and the cationic charge level can be adjusted by the formulator. iii) Poly-quaternary ammonium compounds A preferred composition of the present invention comprises at least about 0.2%, preferably from about 0.2% to about 10%, more preferably from about 0.2% to about 5% by weight, of an enhancer of cationic charge that has the formula: R1 R 1 + l l + R2- N-R- N- R2 2 X "I R 1 R 1 wherein R is unsubstituted or substituted C 2 -C 2 alkylene, unsubstituted or substituted C 2 -C 2 2 -hydroxyalkylene; each R1 is independently C 1 -C 4 alkyl, each R 2 is independently C 1 -C 22 alkyl, C 3 -C 22 alkenyl, R 5 -Q- (CH 2) m-, in which R 5 is C 2 C22 alkyl, C 3 -C 22 alkenyl, and mixtures thereof; m is from 1 to about 6; Q is a carbonyl unit as defined above, and mixtures thereof; X is an anion.

Dispersibility Aids Relatively concentrated compositions can be prepared containing saturated and unsaturated quaternary ammonium diester compounds which are stable without the addition of concentration aids. However, the compositions of the present invention may require organic and / or inorganic concentrating aids to reach even higher concentrations and / or to meet higher stability standards depending on the other ingredients. These concentration aids which typically can be viscosity modifiers may be needed, or preferred, to ensure stability under extreme conditions when particular levels of softening active are used. The surfactant concentration aids are typically selected from the group consisting of (1) individual long chain alkyl cationic surfactants; (2) nonionic surfactants; (3) amine oxides; (4) fatty acids; and (5) mixtures thereof. These auxiliaries are described in the co-pending application of P & G serial number 08/461, 207, filed on June 5, 1995, Wahl et al., Specifically on page 14, line 12 to page 20, line 12, which is incorporated herein by reference. The preferred dispersing aids are GENAMINE® and GENAPOL® from Ciariant. When PVP is present in the compositions of the present invention, a preferred embodiment comprises a cocoylethoxylated amine and a cocoylated alcohol, in which the ethoxylation is about 10, each of which is available as GENAMINE® and GENAPOL®. A preferred example of the use of this mixture is a composition comprising, for example, 0.2% of GENAMINE® and GENAPOL®. When said dispersibility aids are present, the total level is 0.1%, preferably 3%, more preferably 4%, and more preferably 5% to 25%, preferably 17%, more preferably 15%, more preferably to 13% by weight, of the composition. These materials may be added as part of the raw material of active softener, for example, the mono-long chain alkyl cationic surfactant and / or the fatty acid which are reagents used to form the fabric softening active as described above, or added as a separate component. The total level of dispersibility aid includes any amount that may be present as part of the softening active. Dirt release agents In particular with the fabric softener embodiments that are added in the rinse according to the present invention, certain dirt release agents not only provide the dirt release properties described below but are added by its ability to maintain adequate viscosity, especially in non-isotropic, dispersed phase compositions. Any polymeric soil release agent known to the person skilled in the art can optionally be used in the compositions and methods of this invention. Polymeric soil release agents are characterized by having hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit on the hydrophobic fibers and remain adhered to them through the conclusion of the rinse cycle and, therefore, serve as an anchor for the hydrophilic segments. This may allow stains that occur subsequent to treatment with the soil release agent to be more easily cleaned in subsequent washing procedures.
