Description

FABRIC ENHANCEMENT COMPOSITIONS

FIELD OF THE INVENTION The present application relates to fabric care compositions which comprise one or more lysine and/or ornithine based polymers which provide enhanced fabric appearance benefits. The high molecular weight polyamino acids of the present invention which mitigate fabric damage and improve fabric appearance can be combined with other fabric softener actives to provide more complete mitigation of fabric damage.

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.

The preferred polymers which compnse D units which are amide moieties are those which have the nitrogen atoms of the amide unit highly substituted so the nitrogen atoms are m effect shielded to a varying degree by the surrounding non-polar groups. This provides the polymers with an amphiphihc character. Non-limitmg examples include polyvmyl-pyrrohdones, polyvmyloxazo dones, N,N-dιsubstιtuted polyacrylamides, and N,N-dιsubstιtuted polymethacrylamides.

The amide containing polymers may be present partially hydrolyzed and/or crosslinked forms. A preferred polymenc compound for the present invention is polyvmylpyrrolidone

(PVP) This polymer has an amphiphihc character with a highly polar amide group conferring hydrophilic and polar-attractmg properties, and also has non-polar methylene and methine groups, the backbone and/or the πng, confernng hydrophobic properties. The nngs may also provide planar alignment with the aromatic nngs m the dye molecules. PVP is readily soluble in aqueous and organic solvent systems. PVP is available ex ISP, Wayne, New Jersey, 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.

Polymers Comprising N-oxide Units

Another D unit which provides dye transfer inhibition enhancement to the fabnc abrasion reducing polymers descnbed herein, are N-oxide units having the formula:

wherein R', R², and R³ 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 polyamme, i.e., polyalkyleneamme 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 polyethyleneimme N-oxide. Non-limitmg examples of groups which can comprise an N-oxide moiety include the N-oxides of certain heterocycles inter aha pyπdme, pyrrole, lmidazole, pyrazole, pyrazme, pyπmidine, pyπdazme, pipendme, pyrrohdine, pyrro done, azohdme, morpholme. A preferred polymer is poly(4- vmylpyndmg N-oxide, PVNO). In addition, the N-oxide unit may be pendant to the πng, for example, aniline oxide.

N-oxide comprising polymers of the present invention will preferably have a ration of N- oxidized amme 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. For example, the formulator may co-polymenze N-oxide compnsmg monomers with non N-oxide comprising monomers to arnve at the desired ratio of N-oxide to non N-oxide ammo units, or the formulator may control the oxidation level of the polymer dunng preparation. The amme oxide unit of the polyamme N-oxides of the present invention have a Pk_a 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 compnsmg 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. Polymers Compnsmg Amide Units and N-oxide Units

A further example of polymers which are fabnc abrasion reducing polymers which have dye transfer inhibition benefits are polymers which compnse both amide units and N-oxide units as described herein above. Non-limiting examples include co-polymers of two monomers wherein the first monomer compnses 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 mixed amide/N-oxide polymers. However, the resulting polymers must retain the water solubility requirements described herein above. Molecular weight

For all the above described fabπc abrasion reducing polymers of the invention, it is most preferred that they have a molecular weight the range as descnbed 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 polymer is capable of remaining on the fabnc dunng subsequent use and subsequent laundenng of the fabπc. Further, it is believed that for a given charge density, increasing the molecular weight will increase the substantivity of the polymer to the fabnc surface. Ideally the balance of charge density and molecular weight will provide both a sufficient rate of deposition onto the fabπc surface and a sufficient attraction to the fabnc dunng subsequent wash cycles. Increasing molecular weight is considered preferable to increasing charge density as it allows a greater choice the range of matenals 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 treated 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 matenal. Dye Fixing Agents

The compositions of the present invention optionally compnse from about 0.001%, preferably from about 0.5% to about 90%, preferably to about 50%, more preferably to about 10%), most preferably to about 5% by weight, of one or more dye fixing agents.

Cationic fixatives are available under vaπous trade names from several suppliers. Representative examples include- CROSCOLOR PMF (July 1981, Code No 7894) and CROSCOLOR NOFF (January 1988, Code No. 8544) ex Crosfield; LNDOSOL E-50

The cellulose reactive dye fixatives may be suitably combined with one or more dye fixatives descnbed herein above in order to compnse a "dye fixative system". The term "cellulose reactive dye fixing 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 Reactivity Test (CRT) Four pieces of fabπc 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 "lmen fabnc" 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 which has been treated by the ironing calender) are washed separately m Launder-O-Meter pots under typical conditions with a commercial detergent used at the recommended dosage for Vi hour at 60°C, followed by a thorough nnsmg of 4 times 200 ml of cold water and subsequently line dπed.

Color fastness is then measured by compaπng 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 m ASTM D2244. In general, DE values relate to the magnitude and direction of the difference between two psychophysical color stimuli defined by tπstimulus 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 Fπele-Mac Adam-Chickeπng 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 m 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. 35

Crystal Growth Inhibition Test CCGiD

The suitability of a matenal 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., descnbed m "Calcium Phosphate Nucleation and Growth m Solution", Prog Crystal Growth Charact , Vol 3, 77-102, (1980), incorporated herein by reference, is a method which is suitable for evaluating compounds for their crystal growth inhibition The graph below serves as an example of a plot indicating the time delay (t-lag) m crystal formation afforded by a hypothetical crystal growth inhibitor.

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. Exemplary Procedure Combine m a suitable vessel, 2.1M KC1 (35 mL), 0.0175M CaCl₂ (50mL), 0.01M

KH₂PO₄ (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 10⁶ 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) m 1 L of distilled water the pH of which is adjusted to 2.5 by the addition of sufficient 6N HC1 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 rmsmg procedure is repeated six more time after which the pH of the solution is adjusted to neutrality using 2N HC1 The resulting slurry can be stored at 37°C for eleven months.

Crystal growth inhibitors which are suitable for use m 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 10⁶M Crystal growth inhibitors are differentiated form chelatmg 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 a solution of 0 1 ionic strength when measured at 25° C, of less than 15, preferably less than 12.

As stated herein above cis and trans isomers can be used, preferably with a cisl trans 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: 1 , however, the minimum being 1: 1.

The level of unsaturation contained within the tallow, canola, or other fatty acyl unit chain can be measured by the Iodme Value (IV) of the corresponding fatty acid, which m the present case should preferably be m the range of from 5 to 100 with two categories of compounds being distinguished, having a IV below or above 25.

Indeed, for compounds having the formula:

+

(R)- -N- (CH₂)_n-Q-R' X

4-m

derived from tallow fatty acids, when the Iodme Value is from 5 to 25, preferably 15 to 20, it has been found that a cisl trans isomer weight ratio greater than about 30/70, preferably greater than about 50/50 and more preferably greater than about 70/30 provides optimal concentrabihty.

For compounds of this type made from tallow fatty acids having a Iodine Value of above 25, the ratio of cis to trans isomers has been found to be less cntical unless very high concentrations are needed. A further preferred embodiment of the present invention compnses DEQA's wherein the average Iod e Value for R^ IS approximately 45.

The R! units suitable for use in the lsotropic liquids present invention can be further charactenzed m that the Iodme Value (IV) of the parent fatty acid, said IV is preferably from about 10, more preferably from about 50, 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 Iodme Values outside the range listed herein above. For example, "hardened stock" (IV 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 prefered source of fatty acyl units, especially fatty acyl units having branching, for example, "Guerbet branching", methyl, ethyl, etc. units substituted along the pnmary 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 occunng" position, for example, at the third carbon of a Ci 7 chain. What is meant herein by the term "non-naturally occuπng" 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 tnglycendes descnbed 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 matenals or with other natural tnglyceπde denved sources of acyl units.

The following are examples of preferred softener actives according to the present invention.

Pnncipal solvent

The compositions of the present invention, preferably the isofropic liquid embodiments thereof, may also optionally comprise a principal solvent. The level of pnncipal 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 Some embodiments of isofropic liquid embodiments of the present invention may compnse no pnncipal solvent but may substitute instead a suitable nomonic surfactant.

The pnncipal solvents of the present invention are pnmaπly used to obtain liquid compositions having sufficient clanty and viscosity. Pnncipal solvents must also be selected to mmmize 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 pnncipal solvent because it has a relatively strong odor.

Pnncipal solvents are also selected for their ability to provide stable compositions at low temperatures, preferably compositions compnsmg suitable pnncipal solvents are clear down to about 4° C and have the ability to fully recover their clanty if stored as low as about 7° C.

The pnncipal solvents according to the present invention are selected base upon their octanol/water partition coefficient (P). The octanol/water partition coefficient is a measure of the ratio of the concentrations of a particular pnncipal solvent m octanol and water at equihbπum. The partition coefficients are conveniently expressed and reported as their loganthm to the base 10; logP.

The logP of many pnncipal solvent species has been reported; for example, the Ponmona92 database, available from Daylight Chemical Information Systems, Inc.(Dayhght CIS), contains many, along with citations to the oπgmal literature. However, the logP values are most conveniently calculated by the "CLOGP" program, also available from Daylight CIS. This program also lists expenmental logP values when they are available m the Pomona92 database. The "calculated logP" (ClogP) is determined by the fragment approach of Hansch and Leo ( cfi, A. Leo, m Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B Taylor and C. A. Ransden, Eds., p. 295, Pergamon

Press, 1990, incorporated herein by reference). 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. Expenmental log P values represent a less preferred embodiment of the invention Where expenmental 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., Cnppen's fragmentation method as disclosed m J Chem Inf Comput Set , 27a,21 (1987); Viswanadhan's fragmentation method as disclosed m J Chem Inf Comput. Sci , 29, 163 (1989), and Broto's method as disclosed m Eur J Med Chem - Chim. Theor., 19, 71 (1984).

The pnncipal 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 pnncipal solvent is at least to some degree an asymmetric molecule, preferably having a melting, or solidification point which allows the pnncipal 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 asymmetπcal.

Hvdrophobic Dispersant

A preferred composition of the present invention compnses from about 0.1%, preferably from about 5%, more preferably form about 10% to about 80%, preferably to about 50%, more preferably to about 25% by weight, of a hydrophobic polyamme dispersant having the formula:

A further descnption of polyamme dispersants suitable for use in the present invention is found in U.S. 4,891,160 Vander Meer, issued January 2, 1990; U.S.4,597,898, Vander Meer, issued July 1 , 1986, European Patent Application 111 ,965, Oh and Gossehnk, published June 27, 1984, European Patent Application 111,984, Gossehnk, published June 27, 1984, European Patent Application 112,592, Gossehnk, published July 4, 1984; U.S. 4,548,744, Connor, issued October 22, 1985; and U.S. 5,565,145 Watson et al., issued October 15, 1996; all of which are included herein by reference However, any suitable clay/soil dispersent or anti-redepostion agent can be used in the laundry compositions of the present invention. Electrolyte

The fabnc softening embodiments of the compositions of the present invention, especially clear, isotropic liquid fabπc softening compositions, may also optionally, but preferably compnse, one or more electrolytes for control of phase stability, viscosity, and/or clanty. For example, the presence of certain electrolytes inter a a calcium chlonde, magnesium chlonde may be key to insuπng 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 fabnc softener compositions can be introduced into the rmse 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 active only dunng the nnse 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 "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 m the art of fabnc softener compositions will recognize that the level of electrolyte is also influenced by other factors inter aha the type of fabnc softener active, the amount of pnncipal solvent, and the level and type of nomonic surfactant. For example, tnethanol amine denved ester quaternary ammes suitable for use as softener actives according to the present invention are typically manufactured m such a way as to yield a distribution of mono- , di-, and tπ- estenfied quaternary ammonium compounds and amme precursors. Therefore, as in this example, the vaπabihty in the distnbution of mono-, di-, and tπ- esters and ammes may predicate a different level of electrolyte. Therefore, the formulator must consider all of the ingredients, namely, softener active, nomonic surfactant, and m the case of isotropic liquids, the pnncipal solvent type and level, as well as level and identity of adjunct ingredients before selecting the type and/or level of electrolyte

A wide vanety of lomzable salts can be used. Examples of suitable salts are the hahdes of the Group IA and IIA metals of the Penodic Table of the elements, e.g., calcium chloride, sodium chloride, potassium bromide, and lithium chloπde. The lomzable salts are particularly useful during the process of mixing the ingredients to make the compositions herein, and later to obtain the desired viscosity. The amount of lomzable 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 polyammomum salts can be incorporated into the composition to give viscosity control m addition to or m place of the water-soluble, lomzable salts above, In addition, these agents can act as scavengers, forming ion pairs with anionic detergent carried over from the mam wash, in the πnse, and on the fabncs, 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 polyammomum salts include L-lysme, monohydrochloπde and 1,5-dιammonιum 2-methyl pentane dihydrochloπde. Cationic Charge Boosters

The compositions or the present invention may optionally compnse one or more cationic charge boosters, especially to the nnse-added fabnc softening embodiments of the present invention. Typically, ethanol is used to prepare many of the below listed ingredients and is therefore a source of solvent into the final product formulation. The formulator is not limited to ethanol. but instead can add other solvents inter aha hexyleneglycol to aid in formulation of the final composition. This is especially true m clear, translucent, isotropic compositions

The preferred cationic charge boosters of the present invention are descnbed herein below. l) Quaternary Ammonium Compounds

Polyvmyl amines are especially preferred for use as cationic charge booster m liquid fabnc softening compositions since the greater number of amme moieties per unit weight provides substantial charge density. In addition, the cationic charge is generated in situ and the level of cationic charge can be adjusted by the formulator. 111) Polv-Ouaternarv Ammonium Compounds A preferred composition of the present invention compnses 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 cationic charge booster having the formula:

X is a softener compatible anion, preferably the anion of a strong acid, for example, chloπde, bromide, methylsulfate, ethylsulfate, sulfate, nitrate and mixtures thereof, more preferably chloπde and methyl sulfate. Dispersibilitv Aids 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 ensunng stability under extreme conditions when particular softener active levels are used. The surfactant concentration aids are typically selected from the group consisting of (1) single long chain alkyl cationic surfactants; (2) nomonic surfactants; (3) amme oxides; (4) fatty acids; and (5) mixtures thereof. These aids are descnbed in P&G Copendmg Application Senal No. 08/461,207, filed June 5, 1995, Wahl et al., specifically on page 14, line 12 to page 20, line 12, which is herein mcoφorated by reference.

The total level of dispersibihty aid includes any amount that may be present as part of the softener active. Soil Release Agents

Particular to the embodiments of the nnse-added fabric softeners according to the present invention, certain soil release agents provide not only the below descnbed soil release properties but are added for their suitability m maintaining proper viscosity, especially in the dispersed phase, non-isotropic compositions. Any polymeric soil release agent known to those skilled in the art can optionally be employed m the compositions and processes of this invention. Polymenc soil release agents are charactenzed by having both hydrophilic segments, to hydrophihze 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 nnsmg cycle and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occurnng subsequent to treatment with the soil release agent to be more easily cleaned m later washing procedures.
