Description

COMPOSITION YOUR FABRIC VIZRDOR CONTAINING CLQRQ BARREDORS TECHNICAL FIELD The present invention relates to liquid and solid fabric softening compositions containing a low level of chlorine scavenger. The compositions minimize the gradual loss of fabric colors sensitive to low levels of the chlorine present in the rinse water.

BACKGROUND PE INVENTION Chlorine is used in many parts of the world to purify water. To ensure that the water is safe, a small amount of waste, typically about 1 to 2 parts per million (ppm), of chlorine is left in the water. At least approximately 102 of the geography of the States You have about 2 ppm or more of chlorine in your drinking water at some time. It has been discovered that this small amount of chlorine in drinking water can cause the gradual loss of some fabric dyes. The use of laundry detergent compositions containing chlorine scavengers is known in the art to reduce the gradual loss of colors. However, it has now been found that a scavenger with less chlorine, incorporated in fabric softener compositions with rinsing, provides a benefit comparable to detergent compositions containing larger amounts of chlorine scavengers. It is believed that in a typical wash, there is usually enough dirt on the fabrics to sweep the chlorine residue and to minimize damage to the chlorine-sensitive dyes. However, in the rinse cycle, dirt levels are greatly reduced and some colorants may discolor after multiple wash cycles. In this way, the gradual loss of colors in fabrics caused by drinking water over time is more a result of the presence of residual chlorine in the rinse water than in the wash water. This is a problem that the presence of laundry detergent chlorine scavengers, which is omitted after the wash cycle, is unable to be resolved unless a large amount of chlorine scavenger that is retained on the fabrics is used to provide enough residual active for the rinse cycle. A secondary benefit of the rinse softener compositions of the present invention is their ability to eliminate or reduce the chlorine odor in washed fabrics when a chlorine bleach is used in the wash for stain removal or for hygienic purposes. Another secondary benefit is the ability to use water-soluble chlorine scavengers that are not retained in the finished fabric. The retention can cause the fabric to accumulate and discolor and therefore it is not desirable.

(fl) ACTIVE CATIONIC FABRIC SOFTENER BIODESRAPQM F The preferred fabric softener active is a biodegradable cationic ester quaternary ammonium softener active, containing ester linkages in the long hydrophobic groups (EOA) having the formula: E ^ -CY-Ra] m pX-in which is 1 or 2; m is 2 or 3; each E is a quaternary ammonium nitrogen group with charge p +; each Y is -G- (0) C-, or -C (0) -0-; Ra is the same or different hydrocarbyl of CÍÍ-C22 O substituted hydrocarbyl substitute, preferably alkyl and / or alkenyl; and X- is any softening compatible anion such as chloride, bromide, ethylsulfate, ethylsulfate, formate, nitrate and the like; preferably E is selected from the group consisting of: (1) (R) * - m * C (CHa) r,] rn with m being 2 or 3; (2) (R) to N * lCH2) nCH -CHa; and (3) mixtures thereof; where n is 1 ¡i 4; each R is an alkyl group of C-C ". or substituted alkyl (for example, hydroxyalkyl, hydroxyethyl, hydroxypropyl), preferably an alkyl group of C -Ca, for example, methyl, (more preferred), ethyl, propyl, and the like, a benzyl group, hydrogen and mixtures thereof , - and where Ra is derived from fatty acyl groups of C -CZ2. Uri EQA preferred, with E of the formula (1) above, has the formula: (R _m N- C (CHß) "- Y - Ra] m X - where: Y = -0- (0) C-, or -C (0) -0, n = 2 or 3, each n = 1 to 4, each substitute R is a short chain alkyl group of Cx-Cß, preferably of Cx-C3, for example, methyl (more preferred ethyl, propyl, and the like, a hydroxyalkyl group of C-Ca, benzyl, or mixtures thereof, each R 2 is a long chain, preferably at least partially unsaturated, for example, iodine value (IV) of more than about 5 to less than about 100, a Cx hydrocarbyl -Casav or substituted hydrocarbyl group, and the counterion, X ", can be any softening compatible anion, eg, chloride, bromide, methylsulfate, format, sulfate, nitrate and the like. Non-limiting examples of the biodegradable softening actives with E (1) are N, N-di (eeboyloxyethyl) -N, N-dirnethylammonium chloride and N, N-di (tallowoxyethyl) -N- (2- hydroxyethyl) -N-methylammonium. A non-limiting example of a biodegradable softening active with (E) (2) is l, 2-difkyloxy-3-trimethylammoniumpropane chloride. The EQA compounds prepared with fully saturated alkyl groups (R2) are readily biodegradable and excellent softeners. However, the compounds prepared with at least unsaturated alkyl groups, in part have many advantages (i.e., concentrability and good storage viscosity) and are highly acceptable for consumer products. EQA with the unsaturated alkyl groups also provides improved fabric water absorbency compared to EQA with saturated alkyl groups. Variations that must be adjusted to obtain the greatest benefits of using unsaturated fatty acyl groups include the iodine (IV) value of the fatty acids; the weight ratios of cis / trans isomers in the fatty acyl groups; and the smell of fatty acid and / or the EQA. Any reference to the IV values below refers to IV of fatty alkyl / fatty alkyl groups and not to the resulting EQA compound. When the IV of the fatty acyl groups is above about 20, the EQA provides excellent antistatic effect. The antistatic effects are especially important where the fabrics are dried in a drum dryer and / or where the synthetic materials that generate this static are used. The maximum static control occurs with an IV of more than about 20, preferably more than about 40. When the fully saturated EQñ compositions are used, little static control is obtained. Also, formulas with higher smoothing concentrations will typically require higher iodine values. The benefits of concentrability include: use of less packaging material; use of fewer organic solvents, especially volatile organic solvents; use of less concentration aids that can add nothing to performance; etc. As the IV is increased, there is a potential for odor problems. Some already available, highly desirable sources of fatty acids such as tallow have odors that remain with the EQA compound despite the chemical and mechanical process steps that convert raw tallow into finished EQA. Said sources can be deodorized, for example, by means of absorption, distillation (including entrainment such as steam entrainment) etc; as is well known in the art. In addition, care must be taken to minimize the contact of the resulting fatty acyl groups with oxygen and / or bacteria by adding antioxidants, antibacterial agents, etc. The additional expense and effort associated with unsaturated fatty acyl groups is justified by superior know-how and / or performance. For example, the EQA containing unsaturated fatty acyl groups can be concentrated about 13% without the need for additional concentration aids, especially auxiliary surfactant concentration. The EQA derived from highly unsaturated fatty acyl groups, ie fatty acyl groups having a total unsaturation of about 65% by weight, does not provide any further improvement in the effectiveness of antietatic. However, they may be able to provide other benefits such as improved water absorbency of the fabrics. In general, an IV scale of around 40 to about 65 is preferred for concentrability, maximal increase of fatty acyl sources, excellent smoothness, static control, etc. The highly concentrated aqueous dispersions of the diester compounds can gel and / or thicken during storage at low temperature (4.4 ° C). Diester compounds made from only unsaturated fatty acids minimize this problem, but are additionally the most likely to cause malodour formation. The compositions containing diester compounds made from fatty acids having an IV of from about 5 to about 25, preferably from about 10 to about 25, more preferably from about 15 to about 20, and a weight ratio of cis / trans isomer of more than about 30/70, preferably more than about 50/50, more preferably more than about 70/30, are stable for storage at low temperature with minimal odor formation. These weight ratios of cis / trans isomers provide optimal concentration at these IV scales. On the IV scale of about 25, the ratio of cis to trans isomers is less important unless higher concentrations are needed. For any IV, the concentration that will be stable in an aqueous composition will depend on the criterion for stability (eg, stable up to about 5 ° C.; stable up to 0 ° C; it does not gel; it gels but recovers when heated; etc.) and the other ingredients present, but the concentration that is stable can be elevated by adding concentration aids to achieve the desired stability. Generally, the hydrogenation of fatty acids to reduce the polyunsaturation and lower the IV to ensure good color and improved odor and odor stability leads to a high degree of trans configuration in the molecule. However, diester compounds derived from fatty acyl groups having low IV values can be made by mixing the fully hydrogenated fatty acid with slightly hydrogenated fatty acid at a ratio that provides an IV of about 5 to about 25. The polyunsaturation content of the hardened fatty acid should be less than about 5%, preferably less than about 1%. During light hardening, the weight ratios of cis / trans isomers are controlled by means of known methods e > n the technique such as by optimal mixing, using specific catalysts, by providing high H2 availability, etc. The mildly hardened fatty acid with high cis / trans isomer weight ratios is commercially available (ie Radiacid 406 by FINA). It will be understood that R 2 may be optionally substituted with various groups such as alkoxy or hydroxyl groups. Some of the preferred compounds can be considered as variations of dimethyl di-methyl ammonium chloride (DTDMAC), which is a widely used fabric softener. Preferably, at least about 80% of the EQA is the diester. Preferably, less than about 20%, more preferably less than about 10%, must be EQA monoester (e.g., only one -Y-R2 group). As used herein, when the schedule is specified, it will include the monoeter that is normally present. The monoester level can be controlled during the manufacture of EQA. Preferably, part of the monoester is present. The total diester to onoster ratios are from about 100: 1 to about 2: 1, preferably from 50: 1 to about 5: 1, more preferably from about 13: 1 to about 8: 1. Under the high detergent conditions, the monoester ratio is preferably about 11: 1. The liquid compositions of this invention typically contain from about 0.5% to about 50%, preferably from about 1% to about 35%, more preferably from about 4% to about 32%, of an active diester quaternary ammonium softener biodegradable. The granular, solid particle compositions of this invention, as discussed above, typically contain from about 50% to about 95%, preferably from about 60% to about 90%, of acitvo diester quaternary ammonium softener, biodegradab? and.

CB) CHLORINE DRYERS Chlorine scavengers are active agents that react with chlorine, or with materials that generate chlorine, such as hypochlorite. to eliminate or reduce the bleaching activity of chlorine materials. For fabric softener compositions with rinsing, it is suitable to incorporate sufficient chlorine scavenger to neutralize about 10 ppm of chlorine in rinse water, preferably to neutralize about 4 ppm of chlorine, more preferably to neutralize about 2 ppm of chlorine, and still more preferably to neutralize about 1 ppm in rinse water. For the removal or reduction of chlorine odor in fabrics from the use of a chlorine bleach in the wash, the rinse fabric softener composition should contain sufficient chlorine scavenger to neutralize approximately 10 ppm in rinse water. Typically, the softening composition of the present invention provides sufficient chlorine scavenger to react with from about 0.1 ppm to about 40 ppm, preferably from about 0.2 ppm to about 20 ppm, and more preferably from about 0.3 ppm to about 10 ppm of chlorine present in an average rinse bath. Suitable levels of chlorine scavengers in the liquid softening composition of the present invention range from about 0.01% to about 10%, preferably from about 0.02% to about 5%, more preferably from about 0.03% to about 4% . If both the cation and the scavenger anion react with chlorine, which is desirable, the level is adjusted to react with an equivalent amount of available chlorine. Non-limiting examples of chlorine scavengers include amines, preferably primary and secondary amines, including primary and secondary fatty amines, and alkanolamines; ammonium salts, for example, chloride, bromide, citrate, sulfate; functional amine polymers; amino acid homopolymers with amino groups and their salts, such as polyarginines, polyglycine, polyhistidine; amino acid copolymers with amino groups and their salts, but not l, 5-di-ammonium-2-ethyl-panthenium dichloride or Usin monohydrochloride; amino acids and their salts, preferably those having more than one amino group per molecule, such as arginine, histidine, not including plant, reducing anions such as sulfite, bisulfite, thiosulfate, nitrite; antioxidants such as ascorbate, carbamate, phenols; and reread the same. Preferred chlorine scavengers are water soluble, especially low molecular weight, low molecular weight primary, and secondary amines, for example, monoethanolamine, diethanolamine, tris (hydroxymethyl) aminomethane, hexamethylenetetramine. These amines are highly desirable although they require the addition of more acid to counteract their inherent alkalinity. Suitable chlorine scavenger polymers include: water soluble amine functional polymers, for example, polyethylene imines, polyamines, polyamineamides, polyacrylamides, and mixtures thereof. Preferred polymers are polyethylenimines, polyamines, but not cyclic (higher alkyl) amines or their condensation products, and polyamineamides. Preferred polymers for use in the fabric softening compositions in the present invention are polyethyleneimides. Preferred polyethylene imides have a molecular weight of less than about 2000, more preferably from about 200 to about 1500. Preferred chlorine scavengers for use in the fabric softener compositions with rinse of this invention may be liquid or water soluble solid materials. . Chlorine scavengers for use in the rinse fabric moistening compositions of this invention are preferably solid, for example, water soluble amines, amine salts, and / or polymers. It is preferred that amine functional materials that sweep chlorine be neutralized by an acid, before being added to the compositions. This neutralization actually converts the amines into ammonium salts. For liquid compositions and solid compositions with liquid ressitutability, chlorine scavengers containing inorganic polyvalent anions, eg, sulfate, phosphate, can significantly increase the ionic strength of the liquid compositions, thus potentially causing viscosity of adverse composition, for example , gelation. In general, for liquid compositions and solid compositions with liquid ressitutability the preferred polymeric chlorine scavengers have an average molecular weight of less than about 5000, more preferably from about 200 to about 2000, still more preferably from about 200 to about 1000. Low molecular weight polymers are easier to remove from fabrics, resulting in less accumulation of chlorine scavenger and therefore less discoloration of fabrics. Hydrogen peroxide materials that generate hydrogen peroxide such as perborates, percarbonates, percarboxylic acids can function as chlorine scavengers. However, they are outside the scope of the present invention, since they can potentially cause discoloration of the telae color. The fabric conditioning compositions comprising the chlorine scavenger and the active fabric softener can be provided having various ratios and proportions of these materials. Of course, the amount of chlorine scavenger can be varied, depending on the level of residual chlorine expected in the rinse cycle.

(C) OPTIONAL VISCOSITY MODIFIER / DISPERSABIL TDAD The viscosity / dispersibility modifiers may be added for the purpose of concentrating the fabric softening compositions of the present invention. (1) The Cationic Surfactant of Chain Alkyl I a oa In particular The cationic (water-soluble) surfactants of long-chain onoalkyl: (a) in the granular particle compositions are at a level of from 0% to about 30%, preferably from about 3% to about 15%, more about 5% to about 15%, and (b) in the liquid compositions are at a level of 0% to about 30%, preferably from about 0.5% to about 10%, the total individual long chain cationic surfactant present being at least at an effective level. Said long chain rnonoalkyl cationic surfactants, useful in the present invention, are preferably quaternary ammonium salts of the general formula: [R3N (+) R3] X (-) wherein each R group is an alkyl or hydroxyalkyl group from C -Ca, for example, methyl, ethyl, hydroxyethyl, and the like, hydrogen, and mixture thereof; the group R3 is a hydrocarbon group of C3.0-Cs._z, preferably alkyl group of C s »- C ß or the interrupted group of corresponding ester ligation with a short alkylene group (C -C) between the ester ligation and N, and having a similar hydrocarbon group, for example, a fatty acid ester of choline, preferably choline ester (coconut) of C a.-C * and / or tallow choline ester of CX? -C? . Each R and X (-) has the same meaning as above. The above scales represent the amount of the individual long chain alkyl cationic surfactant agent that is added to the composition of the present invention. The scales do not include the amount of monoester that is already present in component (A), the diester quaternary ammonium compound, the total present being at least at an effective level. The long chain Ra group of the individual cationic long chain alkyl cationic surfactant typically contains an alkyl group having from about 10 to about 22 carbon atoms, preferably from about 12 to about 16 carbon atoms for the compositions solid, and preferably from about 12 to about 18 carbon atoms for liquid compositions. This group Ra can be attached to the cationic nitrogen atom through a group consisting of one, or more, ether, amide, ether, amine, etc., ester-bonding groups, preferably ester, which may be desirable for increased hydrolipity , biodegradability, etc. Said ligation groups are preferably within about 3 carbon atoms of the nitrogen atom. Suitable, long chain, individual, long chain alkyl cationic surfactants containing an ester linkage in the long chain are described in US Pat. No. 4,840,738, Hardy and Ualley, issued June 20, 1989, said patent being incorporated herein by reference. If the corresponding non-quaternary amines are used, any acid (preferably a mineral or polycarboxylic acid) which is added to keep the ester groups stable, will also keep the protonated amine in the compositions and preferably during rinsing, so that the amine has a cationic group. The composition is adjusted to a pH of from about 2 to about 5, preferably from about 2 to about 4, to maintain an effective, effective charge density in the concentrated, liquid, aqueous product and at the time of further dilution, for example , to form a less concentrated product and / or at the time of addition for the rinse cycle of a washing process. It will be understood that the main function of the water-soluble cationic surfactant is to decrease the viscosity of the composition and / or increase the dispersibility of the diester softening compound and, therefore, it is not essential that the cationic surfactant has substantial softening properties, although this may be the case. Also, surfactant agents having only one individual long alkyl chain, presumably because they have higher solubility in water, can protect the diester softener from interacting with the anionic surfactants and / or builders that are brought into the rinse. Other cationic materials with ring structures such as alkylaryloline, imidazolinium, pyridine, and pyridinium salts having an individual C ?a-Cas alkyl chain can also be used. Low pH is required to stabilize, for example, imidazoline ring structures. Some alkyloxyzinonium salts useful in the present invention have the general formula: wherein Y =: is -C (0) -0-, -0- (0) -C, -C (0) - (R?), or -N (R7) -C (0) wherein R is hydrogen or a C -C alkyl group; Rs is an alkyl group of Cx-C__; R * and Rβ each independently selected from R and Ra as defined above for the individual long chain surfactant, with only uro being Ra, and X (-) having the same meaning as above. Some alkyl pyridinium salts useful in the present invention have the general formula: where Ra and X (-) are as defined above. A typical material of this type is cetyl pyridinium chloride. Amine oxides can also be used. Suitable amine oxides include those with an alkyl or hydroxyalkyl portion of from about 8 to about 22 carbon atoms, preferably from about 10 to about 18 carbon atoms, more preferably from about 8 to about 14 carbon atoms, and two alkyl portions selected from the group consisting of alkyl group and hydroxyalkyl group with from about 1 to about 3 carbon atoms. Examples include dimethyloctylamine oxide, diethyldecylamine oxide, bis (2-hydroxyethodecylamine oxide, dimethyldodecylamine oxide, dipropyltetradecylamine oxide, methylethylhexadecylamine oxide, dimethyl-2-hydroxyoctadecylamine oxide, and coconut fatty alkyl dimethylamine oxide. (2) Non-ionic Surfactant (Alkoxylated Materials) Suitable nonionic surfactants to serve as the viscosity / dispersibility modifier include ethylene oxide addition products and, optionally, propylene oxide, with fatty alcohols, fatty acids, amines of fat, etc. They are referred to as ethoxylated fatty alcohols, ethoxylated fatty acids, and ethoxylated fatty amines Any of the alkoxylated compounds of the particular type described below can be used as the nonionic surfactant. the present when used alone, in the solid compositions it is at a level of about 5% to about 20%, preferably from about 8% to about 15%, and in the liquid compositions it is at a level of about 0% to about 5%, preferably from about 0.1% to about 5%, more preferably from about 0.2% to about The suitable compounds are substantially water-soluble surfactants of the general formula: R2 - Ya - (Cs, HA0) r, -C3tHA0H wherein R2 for the solid and liquid compositions is selected from the group consisting of branched chain primary and secondary alkyl and / or acyl hydrocarbyl groups; primary, secondary and branched chain alkenyl hydrocarbyl groups; and substituted phenolic hydrocarbyl groups of primary alkyl and alkenyl, branched chain secondary; said hydrocarbyl groups having a hydrocarbyl chain length of from about 8 to about 20, preferably from about 10 to about 18 carbon atoms. More preferably the hydrocarbyl chain length for the liquid compositions is from about 16 to about 18 carbon atoms and for the solid compositions from about 10 to about 14 carbon atoms. In the general formula for the ethoxylated nonionic surfactants herein, Y3 is typically -0-, -C (0) -0-, ~ C (0) N (R) -, or -C (0) N ( R) R-, wherein R2, and R3, when present, have the meanings given above and / or R can be hydrogen, and n is at least about 8, preferably at least about 10-11. The performance and, generally, the stability of the softening composition will decrease when fewer ethoxylated groups are present. The nonionic surfactants herein are characterized by a HLB (hydrophilic-lipophilic balance) of from about 7 to about 20., preferably from about 8 to about 15. Of course, in defining R2 and the number of ethoxylated groups, the HLB of the surfactant is determined, in general. However, it should be noted that the nonionic ethoxylated surfactants useful herein, for the concentrated liquid compositions, contain relatively long chain R 2 groups and are relatively highly ethoxylated. While the shorter alkyl chain surfactant agents having short ethoxylated groups may possess the required HLB, they are not as efficient at present. Nonionic surfactants such as viscosity / dispersibility modifiers are preferred over other modifiers described herein for compositions with higher levels of perfume. Below are examples of nonionic surfactants. The nonionic surfactants of this invention are not limited to these examples. In the examples, the integer defines the number of ethoxy groups (EO) in the molecule. (3) primary alcohol alkoxylates, in straight chain The deca-, undeca-, dodeca-, tetradeca-, and pentadeca-ethoxylate of n-hexadecanol, and n-octadecanol having an HLB within the range cited in the preamble , are useful viecoeity / dispersibility modifiers in the context of this invention. Examples of ethoxylated primary alcohols useful herein or the viscosity / dispersibility modifiers of the compositions are n-EO of C ß (10); and n-EO of C or (ll). Ethoxylates of natural or synthetic alcohols blended in the "bait" chain length scale are also useful herein. Specific examples of such materials include EO of bait alcohol (11), EO of bait alcohol (18), and EO of bait alcohol (25). (4) secondary alcohol akoxylates, in straight chain The deca-, undeca-, dodeca-, tetradeca-, pentadeca-, octadeca-, and nonadeca-ethoxylates of 3-hexadecanol, 2-octadecanol, 4-eicosanol, and 5- eicosanol having a HLB within the scale cited herein, are useful viscosity / dispersibility modifiers in the context of this invention. Examples of ethoxylated secondary alcohols useful herein as the viscosity / dispersibility modifiers of the compositions are: 2-EO of C? (eleven); 2 - E0 of C_ > 0 (11); and 2-EO of CX? (14). (5) allylphenol acoxylates As in the case of alcohol alkoxylates, hexethoxy ethoxylates through octadeca of alkylated phenols, particularly alkylphenols or hydrochlorides, having a HLB within the scale cited herein, are useful as viscosity modifiers / dispersibility of the inetative compositions. The hexa- ethoxylates through octadeca- of p-tridecyl phenol, -pentadecyl phenol, and the like, are useful herein. Examples of ethoxylated alkyl phenols useful as the viscosity / dispersibility modifiers of the mixtures herein are: EO of p-tridecyl phenol (11) and EO of p-pentadecylphenol (18). Cerno is used herein and as is generally recognized in the art, a phenylene group in the non-ionic formula is the equivalent of an alkylene group containing from 2 to 4 carbon atoms. For the present purposes, the nonionic containing a phenylene group is considered to contain an equivalent number of carbon atoms calculated as the sum of the carbon atoms in the alkyl group plus about 3.3 carbon atoms for each phenylene group.

The alkenyl alcohols, both primary and secondary, and the alkenylphenols corresponding to those described immediately above, can be ethoxylated to a HLB within the scale cited herein and used as the viscosity / dispersibility modifiers of the instant compositions. (7) To branched chain cox i-toa Branched chain primary and secondary alcohols which are available from the well-known "0X0" process, can be ethoxylated and used as the viscosity / dispersibility modifiers of the compositions in the present. The above ethoxylated nonionic surfactants are useful in the present compositions alone or in combination, and the term "nonionic surfactant" comprises mixed nonionic surface active agents. (8) Mixtures The term "mixtures" includes the nonionic surfactant and the individual long chain alkyl cationic surfactant added to the composition in addition to any monoester present in the DEQA. Mixtures of the above viscosity / dispersibility modifiers are highly desirable. The individual long chain cationic surfactant provides improved dispersibility and protection for the primary DEQA against anionic surfactants and / or detergency builders that are carried over the wash solution. Mixtures of viscoeity / dielectability modifiers are present for solid compositions at a level of around 3% to about 30%, preferably about 5% to about 20%, and for liquid compositions at a level of about 0.1% to about 30%, preferably from about 0.2% to about 20%, by weight of the composition. < D) OPTIONAL PH MODIFIER Because the diene, cationic, biodegradable quaternary ammonium fabric softening agents are somehow labile to hydrolysis, it is preferable to include optional pH modifiers in the solid particle composition, to which water should be added, to form compositions diluted, stable or softening, liquid, concentrated. Said stable, reconstituted liquid compositions should have a (pure) pH of from about 2 to about 5, preferably from 2 to about 4.5, more preferably from about 2 to about 4. The pH can be adjusted by incorporating an acid Bronsted soluble in water, solid. Examples of suitable Bronsted acids include inorganic mineral acids, such as boric acid, sodium bisulfate, potassium bisulfate, sodium monobasic phosphate, potassium monobasic phosphate, and mixtures thereof; organic acids, such as citric acid, gluconic acid, glutamic acid, tartaric acid, fumaric acid, rnalene acid, alic acid, tannic acid, glycolic acid, chloroacetic acid, phenoxyacetic acid, 1, 2,3,4-butanedicarboxylic acid, acid phonic benzene, ortho-toluene sulphonic acid, paratoluensulonic acid, phenolsulfonic acid, naphthalenesulfonic acid, benzene phosphonic acid, oxalic acid, 1,2,4,5-pyromellitic acid, 1,2,4-trimellitic acid, additic acid, benzoic acid, phenylacetic acid , salicylic acid, succinic acid, and mixtures thereof; and mixtures of mineral inorganic acids and organic acids. Preferred pH modifiers are citric acid, gluconic acid, tartaric acid, malic acid, 1,2,3,4-butacarboxylic acid, and mixtures of the mimes. Optionally, materials that can form solid clathrates such as cyclodextrins and zeolites can be used as adjuvants in the solid particle composition as host vehicles for concentrated liquid acids, such as acetic acid, HCl, sulfuric acid, phosphoric acid, nitric acid, etc. Examples of the inclusion complex of phosphoric acid, sulfuric acid, and nitric acid, and process for their preparation are described in the U.S. patent.

A more complete description of the release agents with dirt is found in U.S. Pat. numbers: 4,661,267, Decker et al., issued on April 28, 1987; 4,711,739, Gosselink et al., Issued December 8, 1987; 4,749,596, Evans et al., Issued June 7, 1988; 4,818,569, Trinh et al., Issued April 4, 1989; 4,877,896, Maldonado et al., Issued October 31, 1989; 4,956,447, Goeeelink et al, issued September 11, 1990; and 4,976,879, Maldonado et al., issued December 11, 1990, said patents incorporated herein by reference. 6. DISPERSANT OF IMPURITY LAYER In the present invention, an optional layering of impurities, different from the soil release agent, can be used. The dispersants of impurity layers preferred herein are formed by highly hydrophobic, highly ethoxylated materialee. The hydrophobic material may be a fatty alcohol, fatty acid, fatty amine, fatty acid amine, amine oxide, quaternary ammonium compound, or the hydrophobic portions used to form the soil release polymers. The dispersants of preferred impurity layers are highly ethoxylated, for example, more than about 17, preferably more than about 25, more preferably more than about 4, moles of ethylene oxide per molecule on average, with the polyethelene oxide portion being from about 76% to about 97%, preferably from about 81% to about 94%, molecular weight + otal. The level of the impurity layer dispersant is sufficient to maintain the impurity layer at an acceptable level, preferably not noticeable to the consumer, under conditions of use, but not sufficient to adversely affect the softening. For some purposes, it is desirable that the impurity layer be non-existent. Depending on the amount of ammonium or non-ionic detergent, etc., used in the wash cycle of a typical washing procedure, the efficiency of the rinse steps will vary before the introduction of the compositions therein, and the hardness of the water, the amount of detergent ammonia or nonionic detergent surfactant and improved detergency (especially phosphates) found in the + elas (laundry). Normally, the minimum amount of impurity layer dispersant should be used to prevent the softening properties from being adversely affected. The impurity layer dispersion typically requires at least about 2%, preferably at least about 4% (at least 6% and preferably at least 10% to avoid the impurity layer as much as possible) based on the level of active softener. However, at levels of about 10% (relative to the softening material) or more, one risks the loss of softening efficiency of the product especially when the fabrics contain high proportions of non-ionic acidic surfactant absorbed during the washing operation. The preferred layer impurities are: BriJR 700, Varonic® U-250; Genapol "T-500, Genapol" T-800; PlurafacR A-79; and Neodol® 25-50. 7. - BACTERIQCIDES Examples of bacteriocides 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 trademark Bronopol®, and a a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one sold by Rohm and Haas Company under the brand Kathon® CG / ICP.
