Description

FABRIC CARE COMPOSITIONS
HAVING REDUCED FABRIC ABRASION

The present invention relates to fabric care compositions which provide fabric enhancement benefits while reducing the damage to fabric from abrasion. The Compositions of the present invention comprise one or more fabric abrasion reducing polymers as well as other ingredients which provide a benefit to the consumer inter alia fabric softening, anti-static, dye fixation.
BACKGROUND OF THE INVENTION
The domestic treatment of fabric is a problem known in the art to the formulator of laundry compositions. Hence, It is well known that alternating cycles of using and laundering fabrics and textiles. such as articles of worn clothing and apparel, will inevitably adversely affect the appearance and integrity of the fabric and textile items so used and laundered. Fabrics and textiles simply wear out over time and with use. Laundering of fabrics and textiles is necessary to remove soils and stains which accumulate therein and thereon during ordinary use. However, the laundering operation itself, over many cycles, can accentuate and contribute to the deterioration of the integrity and the appearance of such fabrics and textiles.
Deterioration of fabric integrity and appearance can manifest itself in several ways.
Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundering. These dislodged fibers may form lint, fuzz or "pills" which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Such a problem of fabric abrasion is even more acute after multiwash cycles.
There exists a long felt need for compositions which provide fabric with protection against damage done due to fabric abrasion. In addition, there is a long felt need to provide compositions Which provide a remedy for fabric abrasion damage.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to compositions which when applied to fabric, reduce the fabric wear and enhance the faabric appearance. These benefits are provided by the surprising discovery that certain polymers which comprise an amide or N-oxide functional unit have fabric abrasion reduction benefits. Surprisingly, it has also been discovered that theses units also provide a secondary benefit; dye transfer inhibition. Therefore the compositions of the present invention provide not only fabric damage amelioration but also fabric color fidelity benefits.
The fabric care compositions of the present invention comprise one or more fabric abrasion reducing polymers as described herein.

The compositions of the present invention provide an efficient fabric abrasion reduction. The term "efficient fabric abrasion reduction" is defined herein as "fabric which has been treated by the herein described compositions have an improved appearance relative to fabrics which have been un-treated by the herein disclosed compositions. The following describe the required elements of the present invention.

-[CK-CRZ]- or -[( i R)X L]-D D
However, the number of D units depends upon the formulation. For example, the number of D
units will be adjusted to provide water solubility of the polymer as well as efficacy of any optional dye transfer inhibition while providing a polymer which has fabric abrasion reducing properties. The molecular weight of the fabric abrasion reducing polymers of the present invention are from about 500, ;preferably from about 1,000, more preferably from about 100,000 most preferably from 160,000 to about 6,000,000, preferably to about 2,000,000, more preferably to about 1,000,000, yet more preferably to about 500,000, most preferably to about 360,000 daltons.

- [CH2-CH2-N]n'-' C=O
CHzCH3 wherein the index n indicates the number of monomer residues present.
The fabric abrasion reducing polymers of the present invention can comprise any mixture of dye transfer inhibition units which provides the product with suitable properties.
The preferred polymers which comprise D units which are amide moieties are those which have the nitrogen atoms of the amide unit highly substituted so the nitrogen atoms are in effect shielded to a varying degree by the surrounding non-polar groups. This provides the polymers with an amphiphilic character. Non-limiting examples include polyvinyl-pyaolidones, polyvinyloxazolidones, N,N-disubstituted polyacrylamides, and N,N-disubstituted I S polymethacrylamides. A detailed description of physico-chemical properties of some of these polymers are given in "Water-Soluble Synthetic Polymers: Properties and Behavior", Philip Molyneux, Vol. I, CRC Press, (1983) .
The amide containing polymers may be present partially hydrolyzed and/or crosslinked forms. A preferred polymeric compound for the present invention is polyvinylpyrrolidone (PVP).
This polymer has an amphiphilic character with a highly polar amide group conferring hydrophilic and polar-attracting properties, and also has non-polar methylene and methine groups, in the backbone and/or the ring, conferring hydrophobic properties.
The rings may also provide planar alignment with the aromatic rings in the dye molecules. PVP is readily soluble in aqueous and organic solvent systems. PVP is available ex ISP, Wayne, New 3ersey, and BASF
Corp., Parsippany, New Jersey, as a powder or aqueous solutions in several viscosity grades, designated as, e.g., K-12, K-15, K-25, and K-30. These K-values indicate the viscosity average molecular weight, as shown below:

Warrington, Pennsylvania, PVP K-15, K-25, and K-30 and poly(2-ethyl-2-oxazoline) are available ex Aldrich Chemical Co., Inc., Milwaukee, Wisconsin. PVP K30 (40,000) through to K90 (360,000) are also commercially available ex BASF under the trademark Luviskol or commercially available ex ISP. Still higher molecular PVP like PVP 1.3MM, commercially available ex Aldrich is also suitable for use herein. Yet further PVP-type of material suitable for use in the present invention are polyvinylpyrrolidone-co-dimethylaminoethylmethacrylate, commercially available commercially ex 1SP in a quaternised form under the trademark Gafquat~ or commercially available ex Aidrich Chemical Co. having a molecular weight of approximately I.OMM;
polyvinylpyrrolidone-co-vinyl acetate, available ex BASF under the trademark Luviskol~, available in vinylpyrrolidone:vinylacetate ratios of from 3:7 to 7:3.
Polymers ComprisingN-oxide Units Another D unit which provides dye transfer inhibition enhancement to the fabric abrasion reducing polymers described herein, are N-oxide units having the formula:
O
Ry ~ -R3 wherein R', R2, and R' can be any hydrocarbyl unit (for the purposes of the present invention the term "hydrocarbyl" does not include hydrogen atom alone). The N-oxide unit may be part of a polymer, such as a polyamine, i.e., polyalkyleneamine backbone, or the N-oxide may be part of a pendant group attached to the polymer backbone. An example of a polymer which comprises an the N-oxide unit as a part of the polymer backbone is polyethyleneimine N-oxide. Non-limiting examples of groups which can comprise an N-oxide moiety include the N-oxides of certain heterocycles inter alia pyridine, pyrrole, imidazole, pyrazole, pyrazine, pyrimidine, pyridazine, piperidine, pyrrolidine, pyrrolidone, azolidine, morpholine. A preferred polymer is poly(4-vinylpyriding N-oxide, PVNO). In addition, the N-oxide unit may be pendant to the ring, for example, aniline oxide.
N-oxide comprising polymers of the present invention will preferably have a ration 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 amount of N-oxide units can be adjusted by the formulator. lror example, the formulator may co-polymerize N-oxide comprising monomers with non N-oxide comprising monomers to arrive at the desired ratio of N-oxide to non N-oxide amino units, or thc: formulator may control the oxidation level of the polymer during preparation. 'fhe amine oxide unit of the polyamine N-oxides of the present invention have a Pka 5 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 N-oxide comprising polymers which provide a dye transfer inhibitor benefit to reduced fabric abrasion polymers is from about 500 daltons, preferably from about 100,000 daltons, more preferably from about 160,000 daltons to about 6,000,000 daltons, preferably to about 2,000,000 daltons, more preferably to about 360,000 daltons.
10 Pol ~~r~ers Comprising Amide Units and N-oxide Units A further example of polymers which are fabric abrasion reducing polymers which have dye transfer inhibition benefits are polymers which comprise both amide units and N-oxide units as described herein above. Non-limiting examples include co-polymers of two monomers wherein the first monomer comprises an amide unit and the second monomer comprises an N-oxide unit. In addition; oligomers or block polymers comprising these units can be taken together to form the rruxed amide/N-oxide polymers. However, the resulting polymers must retain the water solubility requirements described herein above.
Molecular weight For all the above described polymers of the invention, it is most preferred that they have a molecular weight in the range as described herein above. This range is typically higher than the range for polymers which render only dye transfer inhibition benefits alone.
Indeed, the higher molecular weight of the abrasion reducing polymers provides for reduction of fabric abrasion which typically occurs subsequent to treatment, for example during garment use, especially in a later washing ;procedure. Not to be bound by theory, it is believed that the high molecular weight enables the deposition of the polymer on the fabric surface and provides sufficient substantivity so that the poRymer is capable of remaining on the fabric during subsequent use and subsequent laundering of the fabric. Further, it is believed that for a given charge density, increasing the molecular weight will increase the substantivity of the polymer to the fabric surface. Ideally the balance of charge density and molecular weight will provide both a sufficient rate of deposition onto the fabric surface and a :sufficient attraction to the fabric during subsequent wash cycles.
Increasing molecular weight is considered preferable to increasing charge density as it allows a greater choice in the range of materials which can provide the desired benefit and avoids the negative impact that increasing charge density may have inter alia the attraction of soil and residue onto b~eated fabrics. It should be noted, however, that a similar benefit may be predicted from the approach of increasing charge density while retaining a lower molecular weight material.

Dye fixing agents, or "$xatives",' are well-lmown, commercially available materials which are designed to improve the appearance of dyed fabrics by minimizing the loss of dye from fabrics due to washing. Not included within this definition are components which can in some embodiments serve as fabric softener actives.
Many dye fixing agents are cationic, and are based on quaternized nitrogen compound or on nitrogen compounds having a strong cationic charge which is formed in situ under the conditions of usage. Cationic fixatives are available under various trade names from several '1'M
suppliers. Representative examples include: CROSCOLOR PMF (3uly 1981, Code No.

ex Ciba-Geigy. A preferred dye fixing agent for use in the compositions of the present invention is CARTAFIX CB~ ex Clariant.
Other cationic dye fixing agents are described in "Aftertreatments for Improving the Fastness of Dyes on Textile Fibres", Christopher C. Cook, Rev. Prog.
Coloration, Vol. XII, (1982). Dye fixing agents suitable for use in the present invention are ammonium compounds such as fatty acid-diamine condensates inter alia the hydrochloride, acetate, metosulphate and benzyl hydrochloride salts of diamine esters.

The cellulose reactive dye fixatives may be suitably combined with one or more dye fixatives described herein above in order to comprise a "dye fixative system".
The term "cellulose reactive dye firing agent" is defined herein as "a dye fixative agent which reacts with the cellulose fibers upon application of heat or upon a heat treatment either in situ or by the formulator". The cellulose reactive dye fixing agents suitable for use in the present invention can be defined by the following test procedure.
Cellulose ReactivitYTest~CRT) Four pieces of fabric which are capable of bleeding their dye (e.g. 10 x 10 cm of knitted cotton dyed with Direct Red 80) are selected. Two swatches are used as a first control and a second control, respectively. The two remaining swatches are soaked for 20 minutes in an aqueous solution containing 1 % (w/w) of the cellulose reactive dye fixing agent to be tested. The swatches are removed and thoroughly dried. One of the treated swatches which has been thoroughly dried, is passed ten times through an ironing calender which is adjusted to a "linen fabric" temperature setting. The first control swatch is also passed ten times through an ironing calender on the same temperature setting.
All four swatches ( the two control swatches and the two treated swatches, one of each I'M
which has been treated by the ironing calender) are washed separately in Launder-O-Meter pots under typical conditions with a commercial detergent used at the recommended dosage for %z hour at 60°C, followed by a thorough rinsing of 4 times 200 ml of cold water and subsequently line dried.
Color fastness is then measured by comparing the DE values of a new untreated swatch with the four swatches which have undergone the testing. DE values, the computed color difference, is defined in ASTM D2244. In general, DE values relate to the magnitude and direction of the difference between two psychophysical color stimuli defined by tristimulus values, or by chromaticity coordinates and luminance factor, as computed by means of a specified set of color-difference equations defined in the CIE 1976 CIELAB opponent-color space, the Hunter opponent-color space, the 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 is to the un-tested sample and the greater the color fastness benefit.

As the test relates to selection or a cellulose reactive dye fixing agent, if the DE value for the swatch treated in the ironing step has a value which is better than the two control swatches, the candidate is a cellulose reactive dye fixing agent for the purposes of the invention.
Typically cellulose reactive dye fixing agents are compounds which contain a cellulose reactive moiety, non limiting examples of these compounds include halogeno-triazines, vinyl sulphones, epichlorhydrine derivatives, hydroxyethylene urea derivatives, formaldehyde condensation products, polycarboxylates, glyoxal and glutaraldehyde derivatives, and mixtures thereof. Further examples can be found in "Textile Processing and Properties", Tyrone L. Vigo, at page 120 to 121, Elsevier (1997), which discloses specific electrophilic groups and their corresponding cellulose affinity.
Preferred hydroxyethylene urea derivatives include dimethyloldihydroxyethylene, wea, 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, an urea group, a cyanamide group and an aromatic group.

Crystal Growth Inhibition Test (CGTT) 10 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 inorganic micro-crystals. The procedure of Nancollas et al., described in "Calcium Phosphate Nucleation and Growth in Solution", Prog. Crystal Growth Claaract., Vol 3, 77-102, (1980), is a method which is suitable for evaluating compounds for their crystal growth 15 inhibition. The graph below serves as an example of a plot indicating the time delay (t-lag) in crystal formation afforded by a hypothetical crystal growth inhibitor.

t-lag The observed t-lag provides a measure of the compound's efficiency with respect to delaying the growth of calcium phosphate crystal. The greater the t-lag, the more efficient the crystal growth inhibitor.
Exemnlary Procedure Combine in a suitable vessel, 2.1M KCI (35 mL), 0.0175M CaClz (50mL), O.O1M
KH2P04 (50mL), and de-ionized water (350mL). A standard pH electrode equipped with a Standard Calomel Reference electrode is inserted and the temperature adjusted to 37° C while purging of the solution of oxygen. Once the temperature and pH are stabilized, a solution of the crystal growth inhibitor to be test is then added. A typical inhibitor test concentration is 1 x 10'6 M. The solution is titrated to pH 7.4 with 0.05M KOH. The mixture is then treated with 5 mL's of a hydroxyapatite slurry. The hydroxyapatite slurry can be prepared by digesting Bio-Gel~
HTP hydroxyapatite powder (100 g) in 1 L of distilled water the pH of which is adjusted to 2.5 by the addition of sufficient 6N HCl and subsequently heating the solution until all of the hydroxyapatite is dissolved (heating for several days may be necessary). The temperature of the solution is then maintained at about 22° C while the pH is adjusted to 12 by the addition of a solution of 50% aqueous KOH. Once again the solution is heated and the resulting slurry is allowed to settle for two days before the supernatant is removed. 1.5 L of distilled water is added, the solution stirred, then after settling again for 2 days the supernatant is removed. This rinsing procedure is repeated six more time after which the pH of the solution is adjusted to neutrality using 2N HCl. The resulting slurry can be stored at 37°C for eleven months.
Crystal growth inhibitors which 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'~M. Crystal growth inhibitors are differentiated form chelating agents by the fact that crystal growth inhibitors have a low binding affinity of heavy metal ions, i.e., copper.
For example, crystal growth inhibitors have an affinity for copper ions in a solution of 0.1 ionic strength when measured at 25° C, of less than 15, preferably less than 12.

The index m has a value of from 1 to 3; the index n has a value of from 1 to 4, preferably 2 or 3, more preferably 2.
One embodiment of the present invention provides for amines and quaternized amines having two or more different values for the index n per molecule, for example, a softener active prepared from the starting amine methyl(3-aminopropyl)(2-hydroxyethyl)amine.
More preferred softener actives according to the present invention have the formula:

O
-O-C-Rr is a fatty acyl moiety. Suitable; fatty acyl moieties for use in the softener actives of the present invention are derived from sources of triglycerides including tallow, vegetable oils and/or partially hydrogenated vegetable oils including inter alia canola oil, safflower oil, peanut oil, sunflower oil, corn oil, soybean oil, tall oil, rice bran oil. Yet more preferred are the Diester Quaternary Ammonium Compounds (DEQA's) wherein the index m is equal to 2.
The formulator, depending upon the desired physical and performance properties of the final fabric softener active, can choose any of the above mentioned sources of fatty acyl moieties, or alternatively, the formulator can mix sources of triglyceride to form a "customized blend".
However, those skilled in the a.rt of fats and oils recognize that the fatty acyl composition may vary, as in the case of vegetable; oil, from crop to crop, or from variety of vegetable oil source to variety of vegetable oil source:. DEQA's which are prepared using fatty acids derived from natural source:. are preferred.
A preferred embodiment of the present invention provides softener actives comprising R1 units which have at least about 3%, preferably at least about 5%, more preferably at least about 10%, most preferably at least about 15% C11-C22 alkenyl, including polyalkenyl (polyunsaturated) units inter ali,a 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 carbons to 22 carbon atoms including the carbonyl carbon atom, and in the case of alkenyl chains, from one to three double bonds, preferably all double bonds in the cis configuration". With regard to the R1 units of the present invention, it is preferred that at least a substantial percentage of the fatty acyl groups are; unsaturated, e.g., from about 25%, preferably from about 50% to about 70%, preferably to about 65%. The total level of fabric softening active containing polyunsaturated fatty ac;yl groups can be from about 3%, preferably from about 5%, more 5 preferably from about 10°/<. to about 30%, preferably to about 25%, more preferably to about 18%. As stated herein above cis and traps isomers can be used, preferably with a cisltrans ratio is of from 1:1, preferably at least 3:1, and more preferably from about 4:1 to about 50:1, more preferably about 20: l, however, the minimum being 1:1.
T'he level of unsaturation contained within the tallow, canola, or other fatty acyl unit 10 chain can be measured by the Iodine Value (N) of the corresponding fatty acid, which in the present case should preferably be in the range of from S to 100 with two categories of compounds being distinguished, having a N below or above 25.
Indeed, for compounds lhaving the formula:
(R)a-m N~CH~n-Q-RJ X
m 1 S derived from ti~llow fatty acids, when the Iodine Value is from 5 to 25, preferably 15 to 20, it has been found that a cisltrans isomer weight ratio greater than about 30/70, preferably greater than about 50/50 and more preferably greater than about 70/30 provides optimal concentrability.
For compounds of this type made from tallow fatty acids having a Iodine Value of above 25, the ratio of cis to traps isomers has been found to be less critical unless very high 20 concentrations are needed. A i:urther preferred embodiment of the present invention comprises DEQA's wherein the average Iodine Value for R1 is approximately 45.
The R1 units suitable for use in the isotropic liquids present invention can be further characterized in that the Iodine Value (N) of the parent fatty acid, said IV
is preferably from about 10, more: preferably from about S0, most preferably from about 70, to a value of about 140, preferably to about 130, more preferably to about 115. However, formulators, depending upon which embodiment of the present invention they choose to execute, may wish to add an amount of fatty acyl units which have Iodine Values outside the range listed herein above. For example, "hardened stock" (N less than or equal to about 10) may be combined with the source of fatty acid admixture: to adjust the properties of the final softener active.
A prei:ered source of fatty acyl units, especially fatty acyl units having branching, for example, "Guerbet branching", methyl, ethyl, etc. units substituted along the primary alkyl chain, synthetic sources of fatty acyl units are also suitable. For example, the formulator may with to add one or more fatty acyl units having a methyl branch at a "non-naturally occuring" position, for example, at the third carbon of a C1~ chain. What is meant herein by the term "non-naturally occuring" is "acyl units whihc are not found in significant (greater than about 0.1%) quantities is common fats and oils which serve as feedstocks for the source of triglycerides described herein."
If the desired branched chain fatty acyl unit is unavailable from readily available natural feedstocks, therefore, synthetic fatty acid can be suitably admixed with other synthetic materials or with other natural triglyceride derived sources of acyl units.
The following are examples of preferred softener actives according to the present invention.
N,N-di(tallowyl-oxy-etlryl)-N,N-dimethyl ammonium chloride;

Principal solvent The compositions of the present invention, preferably the isotropic liquid embodiments thereof, may also optionally comprise a principal solvent. The level of principal 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%, most preferably less than about 15% by weight.
Sorne embodiments of isotropic liquid embodiments of the present invention may comprise no principal solvent but may substitute instead a suitable nonionic surfactant.
The principal solvents of the present invention are primarily used to obtain liquid compositions having sufficient clarity and viscosity. Principal solvents must also be selected to minmize solvent odor impact in the composition. For example, isopropyl alcohol is not an effective principal solvent in that it does not serve to produce a composition having suitable viscosity. Isopropanol also fails as a suitable principal solvent because it has a relatively strong OdOT.
Principal solvents are also selected for their ability to provide stable compositions at low temperatures, preferably compositions comprising suitable principal solvents are clear down to about 4o C and have the ability to fully recover their clarity if stored as low as about 7o C.
The principal solvents according to the present invention are selected base upon their octanol/water partition coefficient (P). The octanollwater partition coefficient is a measure of the ratio of the concentrations of a particular principal solvent in octanol and water at equilibrium.
The partition coefficients are conveniently expressed and reported as their logarithm to the base 10; loge.

The IogP of many principal solvent species has been reported; for example, the Ponmona92 database, available from Daylight Chemical Information Systems, Inc.(Daylight CIS), contains many, along with citations to the original literature.
However, the loge values are most conveniently calculated by the "CLOGP"
program, S also available from Daylight CIS. This program also lists experimental loge values when they are available in the Pomona92 database. The "calculated loge" (ClogP) is determined by the fragment approach of Hansch and Leo ( cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ransden, Eds., p.
295, Pergamon Press, 1990). The fragment approach is based on the chemical structure of each HR species, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. ClogP values are the most reliable and widely used estimates for octanol water partitioning. It will be understood by those skilled in the art that experimental log P values could also be used. Experimental log P values represent a less preferred embodiment of the invention. Where experimental log P values are used, the one hour log P values are preferred. Other methods that can be used to compute ClogP
include, e.g., Crippen's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 27a,21 (1987);
Viswanadhan's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 29, 163 (1989);
and Broto's method as disclosed in Eur. J. Med. Chem. - Chim. Theor., 19, 71 (1984).
The principal 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, most preferably form about 0.4 to about 0.6. Preferably the principal solvent is at least to some degree an asymmetric molecule, preferably having a melting, or solidification point which allows the principal solvent to be liquid at or near room temperature. Low molecular weight principal solvents may be desirable for some embodiments.
More preferred molecules are highly asymmetrical.

Gamble Co.; WO 97/03170 "Concentrated, Water Dispersible, Stable, Fabric Softening Composition", published January 30, 1997 and assigned to the Procter & Gamble Co.; and WO

Hydrophobic Dispersant A preferred composition of the present invention comprises from about 0. I %, preferably from about 5%, more preferably form about 10% to about 80%, preferably to about SO%, more preferably to about 25% by weight, of a hydrophobic polyamine dispersant having the formula:

wherein R' is methyl or ethyl, m and n are preferably from about 0 to about 50, provided the average value of alkoxylation provided by m + n is at least about 0.5.

However, any suitable clay/soil dispersent or anti-redepostion agent can be used in the laundry compositions of the present invention.
Electrolyte The fabric softening embodiments of the compositions of the present invention, especially clear, isotropic liquid fabric softening compositions, may also optionally, but preferably comprise, one or more electrolytes for 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 insuring initial product clarity and low viscosity, or may affect the dilution viscosity of liquid embodiments, especially isotropic liquid embodiments. Not wishing to be limited by theory, but only wishing to provide an example of a circumstance wherein the formulator must insure proper dilution viscosity, includes the following example. Isotropic or non-isotropic liquid fabric softener compositions can be introduced into the rinse phase of laundry operations via an article of manufacture designed to dispense a measured amount of said composition. Typically the article of manufacture is a dispenser which delivers the softener 2s active only during the rinse cycle. These dispensers are typically designed to allow an amount of water equal to the volume of softener composition to enter into the dispenser to insure complete delivery of the softener composition. An electrolyte may be added to the compositions of the present invention to insure phase stability and prevent the diluted softener composition from S "gelling out" or from undergoing an undesirable or unacceptable viscosity increase. Prevention of gelling or formation of a "swelled", high viscosity solution insures thorough delivery of the softener composition.
However, those skilled in the art of fabric softener compositions will recognize that the level of electrolyte is also influenced by other factors inter alia the type of fabric softener active, the amount of principal solvent, and the level and type of nonionic surfactant. For example, triethanol amine derived ester quaternary amines suitable for use as softener actives according to the present invention are typically manufactured in such a way as to yield 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 predicate a different level of electrolyte. Therefore, the formulator must consider all of the ingredients, namely, softener acaive, nonionic surfactant, and in the case of isotropic liquids, the principal solvent type and level, as well as level and identity of adjunct ingredients before selecting the type and/or level a~f electrolyte A wide variety of ioniz.able salts can be used. Examples of suitable salts are the halides of the Group IA and IIA metals of the Periodic Table of the elements, e.g., calcium chloride, sodium chloride, potassium bromide, and lithium chloride. The ionizable salts are particularly useful during t:he process of mixing the ingredients to make the compositions herein, and later 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 desires of the formulator. Typical levels of salts used to control the composition viscosity 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 composition to give viscosity control in addition to or in plane of the water-soluble, ionizable salts above, In addition, these agents can act as scavengers, forming ion pairs with anionic detergent carried over from the main wash, in the rinse, and on the fabrics, and can improve softness performance.
These agents can stabilized the viscosity over a broader range of temperature, especially at low temperatures, compared to the inorganic electrolytes. Specific examples of alkylene polyammonium salts include L-lysine, monohydrochl,oride and l,5-diammonium 2-methyl pentane dihydrochloride.

Enzymes The compositions and processes herein can optionally employ one or more enzymes inter olio lipases, proteases, cellulose, amylases, mannanases, xyloglucanases, and peroxidases. A
preferred enzyme for use herein is cellulose enzyme. Cellulases usable for use in the fabric enhancement compositions of the present invention include both bacterial and fungal types which preferably exhibit an optimal performance at a pH of from 5 to 9.5. U.S.

Suitable cellulases are also disclosed in GB-A-2.075.028;
GB-A-2.095.275 and DE-OS-2.247.832. CAREZYME~ and CELLUZYME~ (Novo) are especially useful. Other suitable cellulases are also disclosed in WO 91/17243 to Novo, WO 96/34092, WO 96/34945 and EP-A-0,739,982.
Compositions may comprise up to 5 mg by weight, more typically 0.01 mg to 3 mg, of active enzyme per gram of the composition. Stated otherwise, the compositions herein will typically comprise from 0.001 %, preferably from 0.01 % to 5%, preferably to 1 % by weight, of a commercial enzyme preparation. In the particular cases where activity of the enzyme preparation can be defined otherwise such as with cellulases, corresponding activity units are preferred (e.g.
CEVU or cellulose Equivalent Viscosity Units).

Dispersibility Aids 2$ Relatively concentrated compositions containing both saturated and unsaturated diester quaternary ammonium compounds can be prepared that are stable without the addition of concentration aids. However, the compositions of the present invention may require organic and/or inorganic concentration aids to go to 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, for ensuring stability under extreme conditions when particular softener active levels are used. The surfactant concentration aids are 5 typically selected from the group consisting of (1) single long chain alkyl cationic surfactants; (2) nonionic surfactants; (3) amine oxides; (4) fatty acids; and (5) mixtures thereof. These aids are described in U.S. Patent No. 5,545,340.
Preferred dispersibility aids are GENAM1NE~ and GENAPOL~ ex Clariant. When PVP
10 is present in the compositions of the present invention, a preferred embodiment comprises both a cocoyl ethoxylated amine and a cocoyl ethoxylated alcohol, wherein the ethoxylation is approximately 10, each of which are .available as GENAMINE~ and GENAPOL~. A

These materials can either be added as part of the active softener raw material, e.g., the mono-long chain alkyl cationic surfactant andlor the fatty acid which are reactants used 20 to form the fabric softener active as discussed hereinbefore, or added as a separate component.
The total level of dispersibility aid includes any amount that may be present as part of the softener active.
Soil Release A.,gents Particular to the embodiments of the rinse-added fabric softeners according to the present 25 invention, certain soil release agents provide not only the below described soil release properties but are added for their suitability in maintaining proper viscosity, especially in the dispersed phase, non-isotropic compositions.
Any polymeric soil release agent Irnown to those skilled in the art can optionally be employed in the compositions and processes of this invention. Polymeric soil release agents are 30 characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit upon hydrophobic fibers and remain adhered thereto through completion of the rinsing cycle and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occurring subsequent to treatment with the soil release agent to be more easily cleaned in later washing procedures.

If utilized, soil release agents will generally comprise from about 0.01% to about 10.0%, by weight, of the detergent compositions herein, typically from about 0.1% to about 5%, preferably from about 0.2% to about 3.0%.
