CONCENTRATED. WATER DISPERSIBLE. STABLE. FABRIC SOFTENING COMPOSITIONS

TECHNICAL FIELD

The present invention relates to preferably translucent, or, more preferably, clear, aqueous, concentrated, liquid softening compositions useful for softening cloth. It especially relates to textile softening compositions for use in the rinse cycle of a textile laundering operation to provide excellent fabric-softening/static-control benefits, the compositions being characterised especially by excellent water dispersibility, and by e.g., reduced staining of fabric, and excellent rewettability, and/or improved storage and viscosity stability at sub-normal temperatures, i.e., temperatures below normal room temperature, e.g., 25°C.

BACKGROUND OF THE INVENTION

The art discloses problems associated with formulating and preparing clear, concentrated fabric conditioning formulations. For example, European Patent Application No. 404,471, Machin et al., published Dec. 27, 1990, teaches isotropic liquid softening compositions with at least 20% by weight softener and at least 5% by weight of a short chain organic acid.

Fabric softening compositions containing high solvent levels are known in the art. However, softener agglomerates can form when composition is added in the rinse cycle and can deposit on clothes which can result in staining and reduced softening performance. Also, compositions may thicken and/or precipitate at lower temperatures, i.e., at about 40°F (about 4°C) to about 65°F (about 18°C). These compositions can also be costly for the consumer due to the high solvent levels associated with making a concentrated, clear product.

In addition to the problem ofthe above high solvent level, there is a problem that some fabric softeners set to gel, or are thickened or solidified when it is added to rinse water (e.g. when the softener is added to the dispenser of the washing machine). Because of gellation, thickening or solidifying, this type of fabric softener is not be able to dispersed well in rinse water, and softening performance is poor.

For the foregoing reasons, there is a need for a fabric softener which is low in viscosity with low solvent level.

The present invention provides concentrated aqueous liquid textile treatment compositions with relatively low solvent level (i.e., preferably not more than about 50%, by weight ofthe composition), characterised by defined range of molar ratio of organic solvent to fabric softener that have excellent water dispersibility (i.e., low

viscosity and do not gel, thicken, or solidify) and have improved stability (i.e., remain clear or translucent and do not precipitate) at normal, i.e., room temperatures and sub-normal temperatures under prolonged storage conditions. Said compositions also provide reduced staining of fabrics, good cold water dispersibility, together with exceUent softening, anti-static and fabric rewettability characteristics, as well as reduced dispenser residue build-up and exceUent freeze-thaw recovery.

The object of the present invention is to provide aqueous, concentrated, stable, translucent, or, preferably, clear, rinse-added liquid fabric softening compositions which provide excellent water dispersibility in rinse water, acceptable low viscosity and viscosity stability at low temperatures, and/or recovery from freezing.

DETAILED DESCRIPTION OF THE INVENTION I. FABRIC SOFTENING ACTTVΕ

The present invention contains as an essential component, normaUy from about 15% to about 70%, preferably from about 17% to about 65%, more preferably from about 19% to about 60%, by weight ofthe composition, of a fabric softener active selected from the compounds identified hereinafter, and mixtures thereof.

(A) Diester Quaternary Ammonium Fabric Softening Active Compound (DEO >

(1) The first type of DEQA preferably comprises, as the principal active, compounds of the formula

(R)φ _m - . [(CH2)n-Y- R ¹ lι m χ(-)

(1)

wherein: each R substituent is a short chain Cj-Cg, preferably C1-C3 alkyl or hydroxyalkyl group, e.g., methyl (most preferred), ethyl, propyl, hydroxyethyl, and the like, benzyl or mbctures thereof; each m is 2 or 3; each n is from 1 to about 4; each Y is -O-(O)C-, or -C(O O-, but not -OC(O)O-; the sum of carbons in each R ¹ , plus one when Y is -O-(O)C-, is Cg-C22, preferably C14-C20, but no more than one YR ¹ sum being less than about 12 and then the other YR ¹ sum is at least about 16, with each R ¹ being a long chain Cg-C22 (or C7-C2i)hydrocarbyl, or substituted hydrocarbyl substituent, preferably C10-C20 (or C9-C19) alkyl or alkylene, most preferably C12-C18 (or C11-C17) alkyl or alkylene, and where, when said sum of carbons is Cig-Cis and R is a straight chain alkyl or alkylene group, the Iodine Value (hereinafter referred to as IV) of the parent fatty acid of this R ¹ group is preferably from about 40 to about 140, more preferably from about 50 to about 130; and most preferably from about 70 to about 115. (As used herein, the Iodine Value of a "parent" fatty acid, or "corresponding" fatty acid, is used to define a level of unsaturation for an Rl group that is the same as the level of unsaturation that would be present in a fatty acid containing the same R group.)

The counterion, XN) above, can be any softener-compatible anion, preferably the anion of a strong acid, for example, chloride, bromide, methylsulfate, sulfate, nitrate and the like, more preferably chloride. The anion can also, but less preferably, carry a double charge in which case Xv ) represents half a group.

Preferred biodegradable quaternary ammonium fabric softening compounds can contain the group C(O)R* which is derived from unsaturated, and polyunsaturated, fatty acids, e.g., oleic acid, and/or partiaUy hydrogenated fatty acids, derived from vegetable oils and/or partiaUy hydrogenated vegetable oils, such as, canola oil, safflower oU, peanut oil, sunflower oil, corn oil, soybean oil, taU oil, rice bran oil, etc. Νon-limiting examples of DEQAs prepared from preferred fatty acids have the foUowing approximate distributions:

DEQA*- - DEQAlO are prepared from different CommerciaUy available isostearic acids.

The more preferred DEQA's are those that are prepared as a single DEQA from blends of aU the different fatty acids that are represented (total fatty acid blend), rather than from blends of mixtures of separate finished DEQA's that are prepared from different portions ofthe total fatty acid blend.

It is preferred that at least a majority ofthe fatty acyl groups are unsaturated, e.g., from about 50% to 100%, preferably from about 55% to about 95%, more preferably from about 60% to about 90%, and that the total level of active containing polyunsaturated fatty acyl groups (TPU) be from about 3% to about 30%, preferably from about 5% to about 25%, more preferably from about 10% to about 18%. The cis/trans ratio for the unsaturated fatty acyl groups is important, with a cis/trans ratio of from 1:1 to about 50:1, the minimum being 1:1, preferably at least 3:1, and more preferably from about 4:1 to about 20:1. (As used herein, the "percent of softener active" containing a given Rl group is the same as the percentage of that same R group is to the total Rl groups used to form all ofthe softener actives.)

The unsaturated, including the preferred polyunsaturated, fatty acyl groups, discussed hereinbefore and hereinafter, suφrisingly provide effective softening, but also provide better rewetting characteristics, good antistatic characteristics, and especiaUy, superior recovery after freezing and thawing.

The highly unsaturated materials are also easier to formulate into concentrated premixes that maintain their low viscosity and are therefore easier to process, e.g., pump, nύxing, etc. These highly unsaturated materials with only the low amount of solvent that normaUy is associated with such materials, i.e., from about 5% to about 20%, preferably from about 8% to about 25%, more preferably from about 10% to about 20%, weight ofthe total softener/solvent mixture, are also easier to formulate into concentrated, stable compositions of the present invention, even at ambient

temperatures. This ability to process the actives at low temperatures is especiaUy important for the polyunsaturated groups, since it mimimizes degradation. Additional protection against degradation can be provided when the compounds and softener compositions contain effective antioxidants and/or reducing agents, as disclosed hereinafter.

The present invention can contain medium-chain biodegradable quaternary ammonium fabric softening compound, DEQA, as a preferred component, having the above formula (1) and/or formula (2), below, wherein: each Y is -O-(O)C-, or -C(O)-O-, preferably -O-(O)C-; m is 2 or 3, preferably 2; each n is 1 to 4, preferably 2; each R substituent is a Cj-Cg alkyl, preferably a methyl, ethyl, propyl, benzyl groups and mbctures thereof, more preferably a C1-C3 alkyl group; each Rl is a saturated, (the IN is preferably about 10 or less, more preferably less than about 5), (The sum ofthe carbons in R+l is increased by one when Y is -O-(O)C-.) C8-Cj4 preferably a C12-14 hydrocarbyl, or substituted hydrocarbyl substituent and the counterion, X", is the same as above.

Preferably X" does not include phosphate salts.

The saturated C8-C14 fatty acyl groups can be pure derivatives or can be mixed chainlengths.

Suitable fatty acid sources for said fatty acyl groups are coco, lauric, capryUc, and capric acids.

For C12-C14 (or C11-C13) hydrocarbyl groups, the groups are preferably saturated, e.g., the TV is preferably less than about 10, preferably less than about 5.

It wiU be understood that substituents R and R ¹ can optionally be substituted with various groups such as alkoxyl or hydroxyl groups, and can be straight, or branched so long as the R ¹ groups maintain their basically hydrophobic character. The preferred compounds can be considered to be biodegradable diester variations of ditaUow dimethyl ammonium chloride (hereinafter referred to as "DTDMAC"), which is a widely used fabric softener.

A preferred long chain DEQA is the DEQA prepared from sources containing high levels of polyunsaturation, i.e., Ν,Ν-di(acyl-oxyethyl)-Ν,Ν-dimethyl ammonium chloride, where the acyl is derived from fatty acids containing sufficient polyunsaturation, e.g., mbctures of taUow fatty acids and soybean fatty acids. Another preferred long chain DEQA is the dioleyl (nominaUy) DEQA, i.e., DEQA in which N,N-di(oleoyl-oxyethyl)-N,N-dimethyl ammonium chloride is the major ingredient. Preferred sources of fatty acids for such DEQAs are vegetable oils,

and/or partiaUy hydrogenated vegetable oils, such as canola oil, with high contents of unsaturated, e.g., oleoyl groups. Highly preferred medium chain DEQAs are dicocoyl DEQA (derived from coconut fatty acids), i.e., N,N-di(coco-oyl-oxyethyl)- N,N-dimethyl ammonium chloride, exemplified hereinafter as DEQA*-, and N,N- di(lauroyl-oxyethyl)-N,N-dimethyl ammonium chloride.

As used herein, when the diester is specified, it can include the monoester that is present. Preferably, at least about 80% of the DEQA is in the diester form, and from 0% to about 20% can be DEQA monoester, e.g., in formula (1), m is 2 and one YRl group is either H or -C(O)OH. For softening, under no/low detergent carry¬ over laundry conditions the percentage of monoester should be as low as possible, preferably no more than about 5%. However, under high, anionic detergent surfactant or detergent buUder carry-over conditions, some monoester can be preferred. The overaU ratios of diester to monoester are from about 100:1 to about 2:1, preferably from about 50:1 to about 5:1, more preferably from about 13:1 to about 8:1. Under high detergent carry-over conditions, the di/monoester ratio is preferably about 11:1. The level of monoester present can be controUed in manufacturing the DEQA.

The above compounds, used as the biodegradable quatemized ester-amine softening material in the practice of this invention, can be prepared using standard reaction chemistry. In one synthesis of a di-ester variation of DTDMAC, an amine of the formula RN(CH2CH2OH)2 is esterified at both hydroxyl groups with an acid chloride ofthe formula R*C(O)Cl, then quatemized with an alkyl halide, RX, to yield the desired reaction product (wherein R and R ¹ are as defined hereinbefore). However, it wiU be appreciated by those skiUed in the chemical arts that this reaction sequence aUows a broad selection of agents to be prepared.

Yet another DEQA softener active that is suitable for the formulation of the concentrated, clear Uquid fabric softener compositions of the present invention has the above formula (1) wherein one R group is a Cj_4 hydroxy alkyl group, preferably one wherein one R group is a hydroxyethyl group. An example of such a hydroxyethyl ester active is di(acyloxyethyiχ2-hydroxyethyl)methyl ammonium methyl sulfate, wherein the acyl group is the same as that of DEQAl, exemplified hereinafter as DEQA*-".

(2) The second type of DEQA active has the general formula:

wherein each Y, R, R ¹ , and X ") have the same meanings as before. Such compounds include those having the formula:

[CH ₃ ] ₃ N( ⁺ )[CH ₂ CH(CH ₂ O(O)CR ¹ )O(O)CR ¹ ] CI(-)

where each R is a methyl or ethyl group and preferably each R ¹ is in the range of Cj5 to C19. Degrees of branching and substitution can be present in the alkyl(ene) chains. The anion Xv") in the molecule is the same as in DEQA (1) above. As used herein, when the diester is specified, it can include the monoester that is present. The amount of monoester that can be present is the same as in DEQA (1). An example of a preferred DEQA of formula (2) is the "propyl" ester quaternary ammonium fabric softener active having the formula l,2-di(acyloxy)-3-trimethylammoniopropane chloride, wherein the acyl group is the same as that of DEQA ⁵ .

These types of agents and general methods of making them are disclosed in U.S. Pat. No. 4,137,180, Naik et al., issued Jan. 30, 1979, which is incorporated herein by reference..

In preferred softener actives (1) and (2), each Rl is a hydrocarbyl, or substituted hydrocarbyl, group, preferably, alkyl, monounsaturated alkylene, and polyunsaturated alkylene groups, with the softener active containing polyunsaturated alkylene groups being at least about 3%, preferably at least about 5%, more preferably at least about 10%, and even more preferably at least about 15%, by weight ofthe total softener active present; the actives preferably containing mixtures of Rl groups, especiaUy within the individual molecules, and also, optionaUy, but preferably, the saturated Rl groups comprising branched chains, e.g., from isostearic acid, for at least part of the saturated R ¹ groups, the total of active represented by the branched chain groups preferably being from about 1% to about 90%, preferably from about 10% to about 70%, more preferably from about 20% to about 50%.

The DEQAs herein can contain a low level of fatty acid, which can be from unreacted starting material used to form the DEQA and/or as a by-product of any partial degradation (hydrolysis) ofthe softener active in the finished composition. It is preferred that the level of free fatty acid be low, preferably below about 10%, and more preferably below about 5%, by weight ofthe fabric softener active.

π. PRINCIPAL SOLVENT

In order to provide exceUent water dispersibility, the molar ratio of the principal solvent to the fabric softening active should be not less than about 3, preferably from about 3 to about 100, more preferably from about 3.6 to about 50, the most preferably from about 4 to about 25.

Said principal solvent is selected to minimize solvent odor impact in the composition and to provide a low viscosity to the final composition.

The compositions of the present invention comprise less than about 40%, preferably from about 10% to about 35%, more preferably from about 12% to about 25%, and even more preferably from about 14% to about 20%, of the principal solvent, by weight ofthe composition. Said principal solvent is selected to minimize solvent odor impact in the composition and to provide a low viscosity to the final composition. For example, isopropyl alcohol is not very effective and has a strong odor. n-Propyl alcohol is more effective, but also has a distinct odor. Several butyl alcohols also have odors but can be used for effective clarity/stability, especiaUy when used as part of a principal solvent system to minimize their odor. The alcohols are also selected for optimum low temperature stability, that is they are able to form compositions that are liquid with acceptable low viscosities and translucent, preferably clear, down to about 40T (about 4.4°C) and are able to recover after storage down to about 20°F (about 6.7°C).

The suitability of any principal solvent for the formulation of the Uquid, concentrated, preferably clear, fabric softener compositions herein with the requisite stabUity is surprisingly selective. Suitable solvents can be selected based upon their octanol/water partition coefficient (P). Octanol/water partition coefficient of a principal solvent is the ratio between its equilibrium concentration in octanol and in water. The partition coefficients ofthe principal solvent ingredients of this invention are conveniently given in the form of their logarithm to the base 10, logP.

The logP of many ingredients has been reported; for example, the Pomona92 database, available from DayUght Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP" program, also avaUable from DayUght CIS. This program also lists experimental logP values when they are avaUable in the Pomona92 database. The "calculated logP" (ClogP) is determined by the fragment approach of Hansen and Leo (cf, A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansen, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical stmcture of

each ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of the principal solvent ingredients which are useful in the present invention. Other methods that can be used to compute ClogP include, e.g., Crippen's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 27, 21 (1987); Viswanadhan's fragmentation method as disclose 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 herein are selected from those having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, said principal solvent preferably being asymmetric, and preferably having a melting, or solidification, point that aUows it to be Uquid at, or near room temperature. Solvents that have a low molecular weight and are biodegradable are also desirable for some purposes. The more asymmetric solvents appear to be very desirable, whereas the highly symmetrical solvents, having a center of symmetry, such as 1,7-heptanediol, or 1,4- bis(hydroxymethyl)cyclohexane, appear to be unable to provide the essentiaUy clear compositions when used alone, even though their ClogP values faU in the preferred range. One can select the most suitable principal solvent by determining whether a composition containing about 27% di(oleyoyloxyethyl)dimethylammonium chloride, about 16-20% of principal solvent, and about 4-6% ethanol remains clear during storage at about 40°F (about 4.4°C) and recovers from being frozen at about 0°F (about -18°C).

The most preferred principal solvents can be identified by the appearance of the freeze-dried dUute treatment compositions used to treat fabrics. These dUute compositions appear to have dispersions of fabric softener that exhibit a more uni- lameUar appearance than conventional fabric softener compositions. The closer to uni-lameUar the appearance, the better the compositions seem to perform. These compositions provide surprisingly good fabric softening as compared to similar compositions prepared in the conventional way with the same fabric softener active. The compositions also inherently provide improved perfume deposition as compared to conventional fabric softening compositions, especiaUy when the perfiime is added to the compositions at, or near, room temperature.

Operable principal solvents are Usted below under various Ustings, e.g., aliphatic and/or aUcy ic diols with a given number of carbon atoms; monols; derivatives of glycerine; alkoxylates of diols; and mbctures of aU of the above. The

preferred principal solvents are in italics and the most preferred principal solvents are in bold type. The reference numbers are the Chemical Abstracts Service Registry numbers (CAS No.) for those compounds that have such a number. Novel compounds have a method identified, described hereinafter, that can be used to prepare the compounds. Some inoperable principal solvents are also listed below for comparison purposes. The inoperable principal solvents, however, can be used in mixtures with operable principal solvents. Operable principal solvents can be used to make concentrated fabric softener compositions that meet the stability/clarity requirements set forth herein.

Many diol principal solvents that have the same chemical formula can exist as many stereoisomers and/or optical isomers. Each isomer is normally assigned with a different CAS No. For examples, different isomers of 4-methyl-2,3-hexanediol are assigned to at least the following CAS Nos: 146452-51-9; 146452-50-8; 146452-49- 5; 146452-48-4; 123807-34-1; 123807-33-0; 123807-32-9; and 123807-31-8.

In the foUowing listings, for simplicity, each chemical formula is Usted with only one CAS No. This disclosure is only for exemplification and is sufficient to aUow the practice of the invention. The disclosure is not limiting. Therefore, it is understood that other isomers with other CAS Nos, and their mixtures, are also included. By the same token, when a CAS No. represents a molecule which contains some particular isotopes, e.g., deuterium, tritium, carbon-13, etc., it is understood that materials which contain naturally distributed isotopes are also included, and vice versa.

XI. mbctures thereof.

There are no Cι_2 mono-ols that provide the clear concentrated fabric softener compositions of this invention. Only one C3 mono-ol, n-propanol, provides acceptable performance (forms a clear product and either keeps it clear to a temperature of about 4°C, or allows it to recover upon rewarming to room temperature), although its boiling point (BP) is undesirably low. Of the C4 mono- ols, only 2-butanol and 2-methyl-2-propanol provide very good performance, but 2- methyl-2-propanol has a BP that is undesirably low. There are no C5.6 mono-ols that provide clear products except for unsaturated mono-ols as described above and hereinafter.

It is found that some principal solvents which have two hydroxyl groups in their chemical formulas are suitable for use in the formulation of the Uquid concentrated, clear fabric softener compositions of this invention. It is discovered that the suitabiUty of each principal solvent is suφrisingly very selective, dependent on the number of caibon atoms, the isomeric configuration of the molecules having the same number of carbon atoms, the degree of unsaturation, etc. Principal solvents with similar solubUity characteristics to the principal solvents above and possessing at least some asymmetry wiU provide the same benefit. It is discovered that the suitable principal solvents have a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60.

For example, for the 1,2-alkanediol principal solvent series having the general formula HO-CH2-CHOH-(CH2) _n -H, with n being from 1 to 8, only 1,2-hexanediol (n=4), which has a ClogP value of about 0.53, which is within the effective ClogP range offrom about 0.15 to about 0.64, is a good principal solvent, and is within the claim of this invention, while the others, e.g., 1,2-propanediol, 1,2-butanediol, 1,2- pentanediol, 1,2-octanediol, 1,2-decanediol, having ClogP values outside the effective 0.15 - 0.64 range, are not. Furthermore, of the hexanediol isomers, again, the 1,2-hexanediol is a good principal solvent, while many other isomers such as 1,3-

hexanediol, 1,4-hexanediol, 1,5-hexanediol, 1,6-hexanediol, 2,4-hexanediol, and 2,5- hexanediol, having ClogP values outside the effective 0.15 - 0.64 range, are not.

There are no C3-C5 diols that provide a clear concentrated composition in the context of this invention.

Of the nonane isomers, only 2,4-pentadiol, 2,3,3,4-tetramethyl- is highly preferred.

In addition to the aUphatic diol principal solvents, and some of their alkoxylated derivatives, discussed hereinbefore and hereinafter, some specific diol ethers are also found to be suitable principal solvents for the formulation of Uquid concentrated, clear fabric softener compositions of the present invention. Similar to the aliphatic diol principal solvents, it is discovered that the suitabUity of each principal solvent is very selective, depending, e.g., on the number of carbon atoms in the specific diol ether molecules. For example, as given in Table VI, for the glyceiyl ether series having the formula HOCH2-CHOH-CH2-O-R, wherein R is from C2 to C8 alkyl, only monopentyl ethers with the formula HOCH2-CHOH-CH2-O-C5H11 (3-pentyloxy-l,2-propanediol), wherein the C5H11 group comprises different pentyl isomers, have ClogP values within the preferred ClogP values of from about 0.25 to about 0.62 and are suitable for the formulation of Uquid concentrated, clear fabric softeners ofthe present invention. It is also found that the cyclohexyl derivative, but not the cyclopentyl derivative, is suitable. Similarly, selectivity is exhibited in the selection of aryl glyceiyl ethers. Of the many possible aromatic groups, only a few phenol derivatives are suitable.

The same narrow selectivity is also found for the di(hydroxyalkyl) ethers. It is discovered that bis(2-hydroxybutyl) ether, but not bis(2-hydroxypentyl) ether, is suitable. For the di(cycUc hydroxyalkyl) analogs, the bis(2-hydroxycyclopentyl) ether is suitable, but not the bis(2-hydroxycyclohexyl) ether. Non-Umiting examples of synthesis methods for the preparation of some preferred di(hydroxyalkyl) ethers are given hereinafter.

The butyl monoglycerol ether (also named 3-butyloxy-l,2-propanediol) is not weU suited to form Uquid concentrated, clear fabric softeners of the present invention. However, its polyethoxylated derivatives, preferably from about triethoxylated to about nonaethoxylated, more preferably from pentaethoxylated to octaethoxylated, are suitable principal solvents, as given in Table VI.

Even more preferably, said principal alcohol solvent is selected from the groups consisting of 2-ethyl- 1,3 -hexanediol; 1,2-hexanediol; and mixtures thereof.

When several derivatives of the same diol with different aUcyleneoxy groups can be used, e.g., 2-methyl-2,3-butanediol having 3 to 5 ethyleneoxy groups, or 2 propyleneoxy groups, or 1 butyleneoxy group, it is preferred to use the derivative with the lowest number of groups, i.e., in this case, the derivative with one butyleneoxy group. However, when only about one to about four ethyleneoxy groups are needed to provide good formulatabiUty, such derivatives are also preferred.

UNSATURATED DIOLS

It is found surprisingly that there is a clear similarity between the acceptability (formulatabiUty) of a saturated diol and its unsaturated homologs, or analogs, having higher molecular weights. The unsaturated homologs/analogs have the same formulatabiUty as the parent saturated principal solvent with the condition that the unsaturated principal solvents have one additional methylene (viz., CH2) group for each double bond in the chemical formula. In other words, there is an apparent "addition rule" in that for each good saturated principal solvent of this invention, which is suitable for the formulation of clear, concentrated fabric softener compositions, there are suitable unsaturated principal solvents where one, or more, CH2 groups are added while, for each CH2 group added, two hydrogen atoms are removed from adjacent caibon atoms in the molecule to form one carbon-carbon double bond, thus holding the number of hydrogen atoms in the molecule constant with respect to the chemical formula ofthe "parent" saturated principal solvent. This is due to a suφrising fact that adding a -CH2- group to a solvent chemical formula has an effect of increasing its ClogP value by about 0.53, while removing two adjacent hydrogen atoms to form a double bond has an effect of decreasing its ClogP value by about a siπύlar amount, viz., about 0.48, thus about compensating for the - CH2- addition. Therefore one goes from a preferred saturated principal solvent to the preferred higher molecular weight unsaturated analogs/homologs containing at least one more carbon atom by inserting one double bond for each additional CH2

group, and thus the total number of hydrogen atoms is kept the same as in the parent saturated principal solvent, as long as the ClogP value of the new solvent remains within the effective 0.15-0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, range. The following are some Ulustrative examples:

5,6-Dimethyl-6-heptene-l,4-diol (e.g., CAS No. 152344-16-6) is a preferred C9-diol principal solvent and can be considered to be derived by appropriately adding a CH2 group and a double bond to any of the foUowing preferred C8-diol principal solvents: 5-methyl- 1,4-heptanediol; 6-methyl- 1,4-heptanediol; or 4,5-dimethyl-l,3- hexanediol.

Rosiridol (CAS No. 101391-01-9) and isorosiridol (CAS No. 149252-15-3) are two isomers of 3,7-dimethyl-2,6-octadiene-l,4-diol, and are preferred ClO-diol

principal solvents. They can be considered to be derived by appropriately adding two CH2 groups and two double bonds to any of the following preferred C8-diol principal solvents: 2-methyl- 1,3-heptanediol; 6-methyl- 1,3-heptanediol; 3-methyl-l,4- heptanediol; 6-methyl- 1,4-heptanediol; 2,5-dimethyl- 1,3-hexanediol; or 3,5-dimethyl- 1,4-hexanediol.

8-Hydroxylinalool (CAS No. 103619-06-3, 2,6-dimethyl-2,7-octadiene-l,6- diol) is a preferred ClO-diol principal solvent and can be considered to be derived by appropriately adding two CH2 groups and two double bonds to any ofthe foUowing preferred C8-diol principal solvents: 2-methyl- 1,5-heptanediol; 5-methyl-l,5- heptanediol; 2-methyl- 1,6-heptanediol; 6-methyl- 1,6-heptanediol; or 2,4-dimethyl- 1,4-hexanediol.

2,7-Dimethyl-3,7-octadiene-2,5-diol (CAS No. 171436-39-8) is a preferred ClO-diol principal solvent and can be considered to be derived by appropriately adding two CH2 group and two double bond to any of the foUowing preferred C8- diol principal solvents: 2,5-octanediol; 6-methyl- 1,4-heptanediol; 2-methyl-2,4- heptanediol; 6-methyl-2,4-heptanediol; 2-methyl-2,5-heptanediol; 6-methyl-2,5- heptanediol; and 2,5-dimethyl-2,4-hexanediol.

4-Butyl-2-butene-l,4-diol (CAS No. 153943-66-9) is a preferred C8-diol principal solvent and can be considered to be derived by appropriately adding a CH2 group and a double bond to any ofthe foUowing preferred C7-diol principal solvents: 2-propyl-l,4-butanediol or 2-butyl- 1,3-propanediol.

By the same token, there are cases where a higher molecular weight unsaturated homolog which is derived from a poor, inoperable saturated solvent is itself a poor solvent. For example, 3,5-dimethyl-5-hexene-2,4-diol (e.g., CAS No. 160429-40-3) is a poor unsaturated C8 solvent, and can be considered to be derived from the foUowing poor saturated C7 solvents: 3-methyl-2,4-hexanediol; 5-methyl- 2,4-hexanediol; or 2,4-dimethyl-l,3-pentanediol; and 2,6-dimethyl-5-heptene-l,2-diol (e.g., CAS No. 141505-71-7) is a poor unsaturated C9 solvent, and can be considered to be derived from the following poor saturated C8 solvents: 2-methyl- 1,2-heptanediol; 6-methyl- 1,2-heptanediol; or 2,5-dimethyl-l,2-hexanediol.

It is also found, suφrisingly, that there is an exception to the above addition rule, in which saturated principal solvents always have unsaturated analogs/homologs with the same degree of acceptability. The exception relates to saturated diol principal solvents having the two hydroxyl groups situated on two adjacent carbon atoms. In some cases, but not always, inserting one, or more, CH2 groups between the two adjacent hydroxyl groups of a poor solvent results in a higher molecular weight unsaturated homolog which is more suitable for the clear, concentrated fabric

softener formulation. For example, the preferred unsaturated 6,6-dimethyl-l- heptene-3,5-diol (CAS No. 109788-014) having no adjacent hydroxyl groups can be considered to be derived from the inoperable 2,2-dimethyl-3,4-hexanediol which has adjacent hydroxyl groups. In this case, it is more reliable to consider that the 6,6- dimethyl-l-heptene-3,5-diol is derived from either 2-methyl-3,5-heptanediol or 5,5- dimethyl-2,4-hexanediol which are both preferred principal solvents and do not have adjacent hydroxyl groups. Conversely, inserting CH2 groups between the adjacent hydroxyl groups of a preferred principal solvent can result in an inoperable higher molecular weight unsaturated diol solvent. For example, the inoperable unsaturated 2,4-dimethyl-5-hexene-2,4-diol (CAS No. 87604-24-8) having no adjacent hydroxyl groups can be considered to be derived from the preferred 2,3-dimethyl-2,3- pentanediol which has adjacent hydroxyl groups. In this case, it is more reliably to derive the inoperable unsaturated 2,4-dimethyl-5-hexene-2,4-diol from either 2- methyl-2,4-hexanediol or 4-methyl-2,4-hexanediol which are both inoperable solvents and do not have adjacent hydroxyl groups. There are also cases where an inoperable unsaturated solvent having no adjacent hydroxyl groups can be considered to be derived from an inoperable solvent which has adjacent hydroxyl groups, such as the pair 4,5-dimethyl-6-hexene-l,3-diol and 3,4-dimethyl- 1,2-pentanediol. Therefore, in order to deduce the formulatability of an unsaturated solvent having no adjacent hydroxyl groups, one should start from a low molecular weight saturated homolog also not having adjacent hydroxyl groups. I.e., in general, the relationship is more reUable when the distance relationship ofthe two hydroxy groups is maintained. I.e., it is reUable to start from a saturated solvent with adjacent hydroxyl groups to deduce the formulatabiUty ofthe higher molecular weight unsaturated homologs also having adjacent hydroxyl groups.

It has been discovered that the use of these specific principal solvents can produce clear, low viscosity, stable fabric softener compositions at suφrisingly low principal solvent levels, i.e., less than about 40%, by weight of the composition. It has also been discovered that the use ofthe principal alcohol solvents can produce highly concentrated fabric softener compositions, that are stable and can be dUuted, e.g. from about 2:1 to about 10:1, to produce compositions with lower levels of fabric softener that are still stable.

Mbctures ofthe above principal solvents are particularly preferred, since one of the problems associated with large amounts of solvents is safety. Mixtures decrease the amount of any one material that is present. Odor and flammabiUty can also be mimimized by use of mixtures, especially when one ofthe principal solvents is volatUe and/or has an odor, which is more likely for low molecular weight materials.

Suitable solvents that can be used at levels that would not be sufficient to produce a clear product are 2,2,4-trimethyl- 1,3 -pentane diol; the ethoxylate, diethoxylate, or triethoxylate derivatives of 2,2,4-trimethyl-l,3-pentane diol; and/or 2-ethyl-l,3- hexanediol. For the puφoses of this invention, these solvents should only be used at levels that wiU not provide a stable, or clear product. Preferred mixtures are those where the majority of the solvent is one, or more, that have been identified hereinbefore as most preferred. The use of mbctures of solvents is also preferred, especiaUy when one, or more, of the preferred principal solvents are soUd at room temperature. In this case, the mbctures are fluid, or have lower melting points, thus improving processability ofthe softener compositions.

It is also discovered that it is possible to substitute for part of a principal solvent or a mixture of principal solvents of this invention with a secondary solvent, or a mbcture of secondary solvents, which by themselves are not operable as a principal solvent of this invention, as long as an effective amount of the operable principal solvent(s) of this invention is still present in the Uquid concentrated, clear fabric softener composition. An effective amount of the principal solvent(s) of this invention is at least greater than about 5%, preferably more than about 7%, more preferably more than about 10% ofthe composition, when at least about 15% ofthe softener active is also present. The substitute solvent(s) can be used at any level, but preferably about equal to, or less than, the amount of operable principal solvent, as defined hereinbefore, that is present in the fabric softener composition.

For example, even though 1,2-pentanediol, 1,3-octanediol, and hydroxy pivalyl hydroxy pivalate (hereinafter, HPHP) having the foUowing formula:

HO-CH2-C(CH3)2-CH2-O-CO-C(CH3)2-CH2-OH (CAS # 1115-20-4) are inoperable solvents according to this invention, mbctures of these solvents with the principal solvent, e.g., with the preferred 1,2-hexanediol principal solvent, wherein the 1,2-hexanediol principal solvent is present at effective levels, also provide Uquid concentrated, clear fabric softener compositions.

Some ofthe secondary solvents that can be used are those Usted as inoperable hereinbefore and hereinafter, as weU as some parent, non-alkoxylated solvents disclosed in Tables VHIA-VmE.

The principal solvent can be used to either make a composition translucent or clear, or can be used to reduce the temperature at which the composition is translucent or clear. Thus the invention also comprises the method of adding the principal solvent, at the previously indicated levels, to a composition that is not translucent, or clear, or which has a temperature where instabiUty occurs that is too high, to make the composition translucent or clear, or, when the composition is clear,

e.g., at ambient temperature, or down to a specific temperature, to reduce the temperature at which instabUity occurs, preferably by at least about 5°C, more preferably by at least about 10°C. The principal advantage ofthe principal solvent is that it provides the maximum advantage for a given weight of solvent. It is understood that "solvent", as used herein, refers to the effect ofthe principal solvent and not to its physical form at a given temperature, since some of the principal solvents are solids at ambient temperature. Alkyl Lactates

Some alkyl lactate esters, e.g., ethyl lactate and isopropyl lactate have ClogP values within the effective range of from about 0.15 to about 0.64, and can form Uquid concentrated, clear fabric softener compositions with the fabric softener actives of this invention, but need to be used at a sUghtly higher level than the more effective diol solvents Uke 1,2-hexanediol. They can also be used to substitute for part of other principal solvents of this invention to form Uquid concentrated, clear fabric softener compositions.

It has been discovered that the use ofthese specific solvents at specific molar ratios to the fabric softening active, namely the molar ratio ofthe principal solvent to the fabric softening active is not less than about 3, provides a final composition having suφrisingly low viscosity and having excellent water dispersibiUty. It has also been discovered that the use ofthese specific solvents at specific molar ratios to the fabric softening active produce clear and stable fabric softener compositions. The amount ofthe principal solvent is not hmited, as long as the molar ratio ofthe solvent to the fabric softening active is not less than 3. Preferably, the compositions of the present invention have low solvent levels such as not more than about 50% by weight of the composition, in order to produce highly concentrated fabric softener compositions. The use of solvent at low level eliminates the high cost of concentration. Also, the lower level of solvents of this type can help to aUeviate flammability issues that may be associated with concentrated products that contain high levels of conventional non-aqueous solvents, i.e., ethanol, isopropanol, and other short chain alcohols. m. OPTIONAL INGREDΓENTS

(A) Low molecular weight water soluble solvents

Low molecular weight water soluble solvents can also be used at levels of from 0% to about 12%, preferably from about 1% to about 10%, more preferably from about 2% to about 8%. The water soluble solvents cannot provide a clear product at the same low levels of the principal solvents described hereinbefore but can provide clear product when the principal solvent is not sufficient to provide

completely clear product. The presence of these water soluble solvents is therefore highly desirable. Such solvents include: ethanol; isopropanol; 1,2-propanediol; 1,3- propanediol; propylene carbonate; etc. but do not include any of the principal solvents (B). These water soluble solvents have a greater affinity for water in the presence of hydrophobic materials like the softener active than the principal solvents.

These materials can either be added as part of the active softener raw material, (formula (1)), e.g., the mono-long chain alkyl cationic surfactant or added as a separate component. The total level of dispersibility aid mcludes any amount that may be present as part of component (1).

(1) Mono-Alkyl Cationic Quaternary Ammonium Compound

When the mono-alkyl cationic quaternary ammonium compound is present, it is typicaUy present at a level offrom about 2% to about 25%, preferably from about 3% to about 17%, more preferably from about 4% to about 15%, and even more preferably from 5% to about 13% by weight ofthe composition, the total mono-alkyl cationic quaternary ammonium compound being at least at an effective level.

Therefore, preferably the compositions of the present invention are essentiaUy free of non-nitrogenous ethoxylated nonionic dispersibUity aids which wUl decrease the overaU softening performance ofthe compositions.

Also, quaternary compounds having only a single long alkyl chain, can protect the cationic softener from interacting with anionic surfactants and or detergent buUders that are carried over into the rinse from the wash solution.

(2) Amine Oxides

The chemical names and CAS numbers for some ofthe above stabilizers which can be used in the compositions ofthe present invention are listed in Table I below.

(E) SoU Release Agent

In the present invention, an optional soU release agent can be added. The addition of the soil release agent can occur in combination with the premix, in combination with the acid/water seat, before or after electrolyte addition, or after the final composition is made. The softening composition prepared by the process ofthe present invention herein can contain from 0% to about 10%, preferably from 0.2% to about 5%, of a soU release agent. Preferably, such a soU release agent is a polymer. Polymeric soU release agents useful in the present invention include copolymeric blocks of terephthalate and polyethylene oxide or polypropylene oxide, and the like.

A preferred soil release agent is a copolymer having blocks of terephthalate and polyethylene oxide. More specificaUy, these polymers are comprised of repeating units of ethylene terephthalate and polyethylene oxide terephthalate at a molar ratio of ethylene terephthalate units to polyethylene oxide terephthalate units of from 25:75 to about 35:65, said polyethylene oxide terephthalate containing polyethylene oxide blocks having molecular weights of from about 300 to about 2000. The molecular weight of this polymeric soil release agent is in the range of from about 5,000 to about 55,000.

Another preferred polymeric soU release agent is a crystallizable polyester with repeat units of ethylene terephthalate units containing from about 10% to about 15% by weight of ethylene terephthalate units together with from about 10% to about 50% by weight of polyoxyethylene terephthalate units, derived from a polyoxyethylene glycol of average molecular weight of from about 300 to about 6,000, and the molar ratio of ethylene terephthalate units to polyoxyethylene terephthalate units in the crystallizable polymeric compound is between 2:1 and 6:1. Examples of this polymer include the commercially avaUable materials Zelcon 4780® (from Dupont) and MUease T® (from ICI).

Highly preferred soil release agents are polymers ofthe generic formula:

in which each X can be a suitable capping group, with each X typicaUy being selected from the group consisting of H, and alkyl or acyl groups containing from about 1 to about 4 carbon atoms, p is selected for water solubility and generally is from about 6 to about 113, preferably from about 20 to about 50. u is critical to formulation in a Uquid composition having a relatively high ionic strength. There should be very Uttle material in which u is greater than 10. Furthermore, there should be at least 20%, preferably at least 40%, of material in which u ranges from about 3 to about 5.

The R ¹⁴ moieties are essentially 1,4-phenylene moieties. As used herein, the term "the R ¹⁴ moieties are essentially 1,4-phenylene moieties" refers to compounds where the R ¹⁴ moieties consist entirely of 1,4-phenylene moieties, or are partially substituted with other arylene or alkarylene moieties, alkylene moieties, alkenylene moieties, or mixtures thereof. Arylene and alkarylene moieties which can be partially substituted for 1,4-phenylene include 1,3-phenylene, 1,2-phenylene, 1,8-naphthylene, 1,4-naphthylene, 2,2-biphenylene, 4,4-biphenylene, and mbctures thereof. Alkylene and alkenylene moieties which can be partially substituted include 1,2-propylene, 1,4- butylene, 1,5-pentylene, 1,6-hexamethylene, 1,7-heptamethylene, 1,8-octamethylene, 1,4-cyclohexylene, and mbctures thereof.

For the R* ⁴ moieties, the degree of partial substitution with moieties other than 1,4-phenylene should be such that the soU release properties of the compound are not adversely affected to any great extent. Generally the degree of partial substitution which can be tolerated wiU depend upon the backbone length of the compound, i.e., longer backbones can have greater partial substitution for 1,4- phenylene moieties. UsuaUy, compounds where the R* ⁴ comprise from about 50% to about 100% 1,4-phenylene moieties (from 0% to about 50% moieties other than 1,4-phenylene) have adequate soU release activity. For example, polyesters made according to the present invention with a 40:60 mole ratio of isophthalic (1,3- phenylene) to terephthaUc (1,4-phenylene) acid have adequate soU release activity. However, because most polyesters used in fiber making comprise ethylene terephthalate units, it is usually desirable to minimize the degree of partial substitution with moieties other than 1,4-phenylene for best soU release activity. Preferably, the R ¹⁴ moieties consist entirely of (i.e., comprise 100%) 1,4-phenylene moieties, i.e., each R* ⁴ moiety is 1,4-phenylene.

For the R^ moieties, suitable ethylene or substituted ethylene moieties include ethylene, 1,2-propylene, 1,2-butylene, 1,2-hexylene, 3 -methoxy- 1,2- propylene, and mbctures thereof. Preferably, the R ¹ ^ moieties are essentiaUy ethylene moieties, 1,2-propylene moieties, or mixtures thereof. Inclusion of a greater percentage of ethylene moieties tends to improve the soil release activity of

compounds. Suφrisingly, inclusion of a greater percentage of 1,2-propylene moieties tends to improve the water solubUity of compounds.

Therefore, the use of 1,2-propylene moieties or a similar branched equivalent is desirable for incorporation of any substantial part of the soil release component in the liquid fabric softener compositions. Preferably, from about 75% to about 100%, are 1,2-propylene moieties.

The value for each p is at least about 6, and preferably is at least about 10. The value for each n usually ranges from about 12 to about 113. TypicaUy the value for each p is in the range offrom about 12 to about 43.

A more complete disclosure of soU release agents is contained in U.S. Pat. Nos.: 4,661,267, Decker, Konig, Straathof, and Gosselink, issued Apr. 28, 1987; 4,711,730, GosseUnk and Diehl, issued Dec. 8, 1987; 4,749,596, Evans, Huntington, Stewart, Wolf, and Zimmerer, issued June 7, 1988; 4,818,569, Trinh, Gosselink, and Rattinger, issued April 4, 1989; 4,877,896, Maldonado, Trinh, and GosseUnk, issued Oct. 31, 1989; 4,956,447, Gosselink et al., issues Sept. 11, 1990; and 4,976,879, Maldonado, Trinh, and Gosselink, issued Dec. 11, 1990, all of said patents being incoφorated herein by reference.

These soil release agents can also act as scum dispersants.

(F) Scum Dispersant

In the present invention, the premix can be combined with an optional scum dispersant, other than the soU release agent, and heated to a temperature at or above the melting point(s) ofthe components.

The preferred scum dispersants herein are formed by highly ethoxylating hydrophobic materials. The hydrophobic material can be a fatty alcohol, fatty acid, fatty amine, fatty acid amide, amine oxide, quaternary ammonium compound, or the hydrophobic moieties used to form soU release polymers. The preferred scum dispersants are highly ethoxylated, e.g., more than about 17, preferably more than about 25, more preferably more than about 40, moles of ethylene oxide per molecule on the average, with the polyethylene oxide portion being from about 76% to about 97%, preferably from about 81% to about 94%, ofthe total molecular weight.

The level of scum dispersant is sufficient to keep the scum at an acceptable, preferably unnoticeable to the consumer, level under the conditions of use, but not enough to adversely affect softening. For some puφoses it is desirable that the scum is nonexistent. Depending on the amount of anionic or nonionic detergent, etc., used in the wash cycle of a typical laundering process, the efficiency of the rinsing steps prior to the introduction of the compositions herein, and the water hardness, the amount of anionic or nonionic detergent surfactant and detergency buUder (especiaUy

phosphates and zeohtes) entrapped in the fabric (laundry) will vary. Normally, the minimum amount of scum dispersant should be used to avoid adversely affecting softening properties. TypicaUy scum dispersion requires at least about 2%, preferably at least about 4% (at least 6% and preferably at least 10% for maximum scum avoidance) based upon the level of softener active. However, at levels of about 10% (relative to the softener material) or more, one risks loss of softening efficacy of the product especiaUy when the fabrics contain high proportions of nonionic surfactant which has been absorbed during the washing operation.

Preferred scum dispersants are: Brij 700®; Varonic U-250®; Genapol T- 500®, Genapol T-800®; Plurafac A-79®; and Neodol 25-50®.

(G) Bactericides

Examples of bactericides used in the compositions of this invention include glutaraldehyde, formaldehyde, 2-bromo-2-nitro-propane-l,3-diol sold by Inolex Chemicals, located in Philadelphia, Pennsylvania, under the trade name Bronopol®, and a mixture of 5-chloro-2-methyl-4-isothiazoUne-3-one and 2-methyl-4- isothiazoline-3-one sold by Rohm and Haas Company under the trade name Kathon® about 1 to about 1,000 ppm by weight ofthe agent.

(H) Perfiime

The present invention can contain any softener compatible perfume. Suitable perfumes are disclosed in U.S. Pat. 5,500,138, Bacon et al., issued March 19, 1996, said patent being incoφorated herein by reference.

As used herein, perfume includes fragrant substance or mbcture of substances including natural (i.e., obtained by extraction of flowers, herbs, leaves, roots, barks, wood, blossoms or plants), artificial (i.e., a mbcture of different nature oUs or oU constituents) and synthetic (i.e., syntheticaUy produced) odoriferous substances. Such materials are often accompanied by auxiliary materials, such as fixatives, extenders, stabilizers and solvents. These aux iaries are also included within the meaning of "perfume", as used herein. TypicaUy, perfumes are complex mixtures of a pluraUty of organic compounds.

Perfiime can be present at a level offrom 0% to about 10%, preferably from about 0.1% to about 5%, and more preferably from about 0.2% to about 3%, by weight ofthe finished composition. Fabric softener compositions ofthe present invention provide improved fabric perfume deposition.

(I) Chelating Agents

The compositions and processes herein can optionally employ one or more copper and/or nickel chelating agents ("chelators") over and above the chelating agent that is part of the stabUizer. Such water-soluble chelating agents can be

selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures thereof, all as hereinafter defined. The whiteness and/or brightness of fabrics are substantiaUy improved or restored by such chelating agents and the stability ofthe materials in the compositions are improved.

Amino carboxylates useful as chelating agents herein include ethylenediaminetetraacetates (EDTA), N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates (NTA), ethylenediamine tetraproprionates, ethylenediamine-N.N ¹ - diglutamates, 2-hyroxypropylenediamine-N,N ^l -disuccinates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates (DETPA), and ethanoldiglycines, including their water-soluble salts such as the alkali metal, ammonium, and substituted ammomum salts thereof and mbctures thereof.

Amino phosphonates are also suitable for use as chelating agents in the compositions of the invention when at least low levels of total phosphorus are permitted in detergent compositions, and include ethylenediaminetetrakis (methylenephosphonates), diethylenetriamine-N,N,N',N",N"-pentakis(methane phos¬ phonate) (DETMP) and l-hydroxyethane-l,l-diphosρhonate (HEDP). Preferably, these amino phosphonates to not contain alkyl or alkenyl groups with more than about 6 carbon atoms.

The chelating agents are typicaUy used in the present rinse process at levels from about 2 ppm to about 25 ppm, for periods from 1 minute up to several hours' soaking.

The preferred EDDS chelator used herein (also known as ethylenediamine- N,N*-disuccinate) is the material described in U.S. Patent 4,704,233, cited hereinabove, and has the formula (shown in free acid form):

As disclosed in the patent, EDDS can be prepared using maleic anhydride and ethylenediamine. The preferred biodegradable [S,S] isomer of EDDS can be prepared by reacting L-aspartic acid with 1,2-dibromoethane. The EDDS has advantages over other chelators in that it is effective for chelating both copper and nickel cations, is avaUable in a biodegradable form, and does not contain phosphorus. The EDDS employed herein as a chelator is typicaUy in its salt form, i.e., wherein one or more ofthe four acidic hydrogens are replaced by a water-soluble cation M, such as sodium, potassium, ammonium, triethanolammonium, and the like. As noted before, the EDDS chelator is also typicaUy used in the present rinse process at levels

from about 2 ppm to about 25 ppm for periods from 1 minute up to several hours' soaking. At certain pHs the EDDS is preferably used in combination with zinc cations.

As can be seen from the foregoing, a wide variety of chelators can be used herein. Indeed, simple polycarboxylates such as citrate, oxydisuccinate, and the Uke, can also be used, although such chelators are not as effective as the amino carboxylates and phosphonates, on a weight basis. Accordingly, usage levels may be adjusted to take into account differing degrees of chelating effectiveness. The chelators herein wiH preferably have a stabUity constant (ofthe fully ionized chelator) for copper ions of at least about 5, preferably at least about 7. TypicaUy, the chelators wiH comprise from about 0.5% to about 10%, more preferably from about 0.75% to about 5%, by weight of the compositions herein. Preferred chelators include DETMP, DETPA, NT A, EDDS and mixtures thereof.

(J) Other Optional Ingredients

The present invention can include optional components conventionaUy used in textile treatment compositions, for example: colorants; preservatives; surfactants; anti-shrinkage agents; fabric crisping agents; spotting agents; germicides; fungicides; anti-oxidants such as butylated hydroxy toluene, anti-corrosion agents, and the Uke.

Particularly preferred ingredients include water soluble calcium and/or magnesium compounds, which provide additional stabUity. The chloride salts are preferred, but acetate, nitrate, etc. salts can be used. The level of said calcium and/or magnesium salts is from 0% to about 2%, preferably from about 0.05% to about 0.5%, more preferably from about 0.1% to about 0.25%.

The present invention can also include other compatible ingredients, including those as disclosed in copending appUcations Serial Nos.: 08/372,068, filed January 12, 1995, Rusche, et al.; 08/372,490, filed January 12, 1995, Shaw, et al.; and 08/277,558, filed July 19, 1994, Hartman, et al., incoφorated herein by reference.

EXAMPLES The compositions in the Examples below are made by first preparing a softener premix by heating the softener active to melting at, e.g., about 130-150T (about 55-66°C). The melted softener active is mixed using an D A RW 25® mixer for about 2 to about 5 minutes at about 150 φm. Separately, an acid/water seat is prepared by mixing the HCl with deionized (DI) water and heating this mixture to

about 100°F (about 38°C) and maintaining said temperature with a water bath. The principal solvent(s) (melted at suitable temperatures if their melting points are above room temperature) are added to the softener premix and said premix is mixed for about 5 minutes. The acid/water seat is then added to the softener premix and mixed for about 20 to about 30 minutes or until the composition is clear and homogeneous.

The composition is allowed to air cool to ambient temperature.
