S~JLFONATE PERFUMES

LAUNDRY AND CLEANING COMPOSITIONS

FIELD OF THE ~NVENTION
The present invention relates to laundry and cleaning products comprising sulfonates of alcohol perfumes.

BACKGROUND OF THE INVENTION
Consumer acceptance of cleaning and laundry products is determined not only by the perforrnance achieved with these products but the aesthetics associated therewith. The perfume systems are therefore an important aspect of the successful formulation of such commercial products.
What perfume system to use for a given product is a matter of carefill consideration by skilled perfumers. While a wide array of chemicals and ingredients are available to perfurners~ considerations such as availability, cost, and compatibility with other components in the compositions limit the practical options.
Thus, there continues to be a need for low-cost, compatible perfurne m~tf ri~l~ useful for cleaning and laundry compositions.
It has been discovered that sulfonates of certain perfume alcohols are particularly well suited for laundry and cleaning compositions. In particular, it has been discovered that sulfonates of perfume alcohols will hydrolyze to give an alcohol perfume and the co..~;s~ollding salt. In addition, hydrolyzable sulfonates of perf lme alcohols provide release of the perfume over a longer period of time than by the use of the perfume itself in the laundry/cleaning compositions. Such materi~ls therefore provide perfumers with more options for perfume ingredients and more flexibility in forrnulation considerations. These and other advantages of the present invention will be seen from the disclosures hereinafter.

Cationic or Nonionic Fabric Softening Agents:
The ~reftl.~d fabric softening agents to be used in the present invention compositions are q~ ly ammonium compounds or amine precursors herein having the formula (III) or (IV), below:

R3\ R2 + I--(CH2)n--Q--T 1 X
Rl (III) or K3\ R3 + Nl--(CH2)n- ICH~ X ~
R3 Ql Q
Tl T2 (IV) wherein:
each Q is -O-C(O)- or -C(O)-O- or-O-C(O)-O- or -NR4-C(o)- or -C(o)-NR4-;

W O 97/22682 PCT~US96/19095 each R~ is (CH2)n-Q-T2 or T3 or R3 eachR2is(CH2)m-Q-T4 or Ts orR3;
each R3 is Cl-C4 alkyl or C l-C4 hydroxyalkyl or H;
each R4 is H or Cl-C4 aLkyl or Cl-C4 hydroxyalkyl;
Tl, T2, T3, T4, Ts are (the same or different) Cll-C22 alkyl or al~enyl;
n and m are integers from l to 4; and X- is a softener-compatible anion, such as chloride, methyl sulfate, etc.
The alkyl, or alkenyl, chain Tl, T2, T3, T4, Ts must contain at least l l carbon~ atoms, preferably at least l 6 carbon atoms. The chain can be straight or branched.
Q, n, Tl, and T2 can be the same or different when more than one is present in the molecule.
Tallow is a convenient and inexpensive source of long chain alkyl and alkenyl material. The compounds wherein Tl, T2, T3, T4, T5 represents the mixture of long chain mzlt~ri~l.e typical for tallow are particularly plef~.~d.
Specific examples of qll~t~rn~y ammonium compounds suitable for use in the aqueous fabric softening compositions herein include:
l) N,N-di(tallowyl-oxy-ethyl)-N,N-dirnethyl ammonium chloride;
2) N,N-di(tallowyl-oxy-ethyl)-N-methyl, N-(2-hydroxyethyl) ammonium chloride;

3) N,N-di(2-tallowyloxy-2-oxo-ethyl)-N,N-dimethyl ammonium chloride;

4) N,N-di(2-tallowyloxyethylcarbonyloxyethyl)-N,N-dimethyl arnmonium chloride;
S)n-(2-tallowoyloxy-2-ethyl)-N-(2-tallowyloxy-2-oxo-ethyl) -N,N-dimethyl ammonium chloride;
6) N,N,N-tri(tallowyl-oxy-ethyl)-N-methyl arnmonium chloride;
7) N-(2-tallowyloxy-2-oxoethyl)-N-(tallowyl)-N,N-dimethyl ~mm~ nium chloride; and 8) 1 ,2-ditallowyloxy-3-N,N,N-trimethylammonio~op~le chloride.;
and nlixLIllcs of any of the above materials.
Of these, compounds 1-7 are examples of compounds of Formula (III);
compound 8 is a conl~owld of Formula (IV).
Particularly plert;lred is N,N-di(tallowoyl-oxy-ethyl)-N,N-dimethyl ammoniurn chloride, where the tallow chains are at least partially unsaturated.
The level of unsaturation of the tallow chain can be measured by the Iodine Value (I.V.) of the colrei,~onding fatty acid, which in the present case should ;fe,dbly be in the range of from S to lOO with two categories of compounds beingdistinguished, having an I.V. below or above 25.

=

W O 97/22682 PCT~US96/19095 Indeed, for compounds of Formula (III) made from tallow fatty acids having a I.V. of from 5 to 25, preferably 15 to 20, it has been found that a cis/trans isomer weight ratio greater than about 30/70, preferably greater than about 50/50 and more preferably greater than about 70/30 provides optimal concentrability.
For compounds of Forrnula (III~ made from tallow fatty acids having a I.V.
o~ above 25, the ratio of cis to trans isomers has been found to be less critical unless very high concentrations are needed.
Other exarnples of suitable qll~t~ y arnmoniums of ForJnula (III) and (IV~
are obtained by, e.g., - replacing "tallow" in the above compounds with, for example, coco, palm, lauryl, oleyl, ricinoleyl, stearyl, palmityl, or the like, said fatty acyl chains being either fully ~a~ul~led, or preferably at least partly unsaturated;
- replacing "methyl" in the above compounds with ethyl, ethoxy, propyl, propoxy, isopropyl, butyl, isobutyl or t-butyl;
- replacing "chloride" in the above compounds with bromide, methylsulfate, formate, sulfate, nitrate, and the like.
In fact, the aniorl is merely present as a counterion of the positively charged qu~t~ . "~y ammonium compounds. The nature of the counterion is not critical at all to the practice of the present invention. The scope of this invention is not considered limited to any particular anion.
By "amine precursors thereofi' is meant the secondarv or tertiary amines corresponding to the above qll~t~rn~ry ammoniurn compounds, said amines being sllhst~nti~lly protonated in the present compositions due to the claimed pH values.
The qll~t~rn~ly ammonium or amine precul~ol~ compounds herein are present at levels of fiom about 1% to about 80% of compositions herein, depending on the composition execution which can be dilute with a pr~relled level of active from about 5% to about 15%, or conce,~ l, with a preferred level of active from about 15% to about 50%, most preferably from about 15% to about 35%.
For the prececling fabric softening agents, the pH of the compositions herein is an irnportant pa~dn.etcr of the present invention. Indeed, it influences the stability of the qll~,. 11;11 y ammonium or amine ~ sOl~ compounds, especially in prolonged storage collditions.
The pH, as defined in the present context, is measured in the neat compositions at 20 ~C. For optimum hydrolytic stability of these compositions, the neat pH, measured in the above-mentioned conditions, must be in the range of from about 2.0 to about 4.5, preferably from about 2.0 to about 3.5. The pH of these compositions herein can be regulated by the addition of a Bronsted acid.

W O 97/22682 PCT~US96/19095 Examples of suitable acids include the inorganic mineral acids, carboxylic acids, in particular the low molecular weight (C 1 -C5) carboxylic acids, and alkylsulfonic acids. Suitable inorganic acids include HCl, HzSO4, HNO3 and H3PO4. Suitable organic acids include forrnic, acetic, citric, methylsulfonic and ethylsulfonic acid. Preferred acids are citric, hydrochloric, phosphoric, formic, methylsulfonic acid, and benzoic acids.
Softening agents also useful in the compositions of the present invention are nonionic fabric softener materials, preferably in combination with cationic softening agents. Typically, such nonionic fabric softener materials have a HLB of from about 2 to about 9, more typically from about 3 to about 7. Such nonionic fabric softener materials tend to be readily dispersed either by themselves, or when combined with other materials such as single-long-chain alkyl cationic surfactant described in detail hereinafter. Dispersibility can be improved by using more single-long-chain alkyl cationic surfactant, mixture with other materials as set forth hereinafter, use of hotter water, and/or more agitation. In general, the materials selected should be relatively crystalline, higher melting, (e.g. >40 ~C) and relatively water-insoluble.
The level of optional nonionic softener in the compositions herein is typically from about 0.1% to about 10%, preferably from about 1% to about 5%.
Preferred nonionic softeners are fatty acid partial esters of polyhydric alcohols, or anhydrides thereof, wherein the alcohol, or anhydride, conlaills from 2 to 18, preferably from 2 to 8, carbon atoms, and each fatty acid moiety containsfrom 12 to 30, preferably from 16 to 20, carbon atoms. Typically, such softenerscontain from one to 3, preferably 2 fatty acid groups per molecule.
The polyhydric alcohol portion of the ester can be ethylene glycol, glycerol, poly (e.g., di-, tri-, tetra, penta-, and/or hexa-) glycerol, xylitol, sucrose, t;l~llui~
pentaerythritol, sorbitol or sorbitan. Sorbitan esters and poly~,lycerol monostearate are particularly ~lc~ll~d.
The fatty acid portion of the ester is normally derived from fatty acids having from 12 to 30, preferably from 16 to 20, carbon atoms, typical e~amples of said fatty acids being lauric acid, myristic acid, palmitic acid, stearic acid, oleic and behenic acid.
Highly ~le~,.~d optional nonionic softening agents for use in the present invention are the so~ esters, which are esterifiçd dehydration products of sorbitol, and the glycerol esters.
Commercial sorbitan monostearate is a suitable m~ter~l Mixtures of sorbitan stearate and sorbitan palmitate having stearate/p~lmit~te weight ratiosvarying between about 10:1 and about 1:10, and 1,5-sorbitan esters are also useful.

W O 97/226g2 PCT~US96/19095 Glycerol and polyglycerol esters, especially glycerol, diglycerol, triglycerol, and polyglycerol mono- and/or di-esters, preferably mono-, are preferred herein (e.g.
polyglycerol monostearate with a trade name of Radiasurf 7248).
Usefill glycerol and polyglycerol esters include mono-esters with stearic, oleic, palmitic, lauric, isostearic, myristic, and/or behenic acids and the diesters of stearic, oleic, palmitic, lauric, isostearic, behenic, and/or myristic acids. It is understood that the typical mono-ester contains some di- and tri-ester, etc.
The "glycerol esters" also include the polyglycerol, e.g., diglycerol through octaglycerol esters. The polyglycerol polyols are formed by con~l~n~in~ glycerin or epichlorohydrin together to link the glycerol moieties ~/ia ether linkages. The mono-and/or diesters of the polyglycerol polyols are plcr~ d, the fatty acyl groups typically being those described hereinbefore for the sorbitan and glycerol esters.

W O 97~2682 PCT~US96/19095 lg tallow)dimethylammonium chloride to said methyl- 1 -tallowamidoethyl-2-tallowimida~olinium methylsulfate is from about 2:1 to about 6:1.
In the cationic nitrogenous salts described hereinbefore, the anion A-provides charge neutrality. Most often, the anion used to provide charge neutrality in these salts is a halide, such as chloride or bromide. However, other anions can be used, such as methylsulfate, ethyl~-llf~te, hydroxide, acetate, formate, cikate, sulfate, carbonate, and the like. Chloride and methylsulfate are preferred herein as anion A-.
Ihe preferred fabric softening compounds of the present invention are biodegradable quaternary ammonium compounds according to II and III as hereinbefore described, wherein, preferably, the fatty acyl groups have an Iodine Value (I.V.) of from greater than about 5 to less than about 100, and, also preferably, a cis/trans isomer weight ratio of greater than about 30/70 when the I.V.
is less than about 25, the level of unsaturation preferably being less than about 65%
by weight. Preferably, the compounds with an I.V. of greater than about 10 are capable of forming concentrated aqueous compositions with concentrations greaterthan about 13% by weight without viscosity modifiers other than normal polar organic solvents present in the raw m~tPri~l of the compound or added eleckolyte, and wherein any fatty acyl groups from tallow are l~refe~ably modified, especially to reduce their odor.
When the I.V. of the fatty acyl groups is above about 20, the softener provides excellent zmti~tzltic effect. ~nti~t~tic effects are especially in,l)ol~lt where the fabrics are dried in a tumble dryer, and/or where synthetic materials which generate static are used. Maximurn static control occurs with an I.V. of greater than about 20, preferably greater than about 40. When fully saturated softener compounds are used in the compositions, poor static control results. Also, as tliccl]~e~l hereinafter, concelllldl~bility increases as I.V. increases. The benefits of col,c~ 91.ility include: use of less p~c~ ing m~t~ri~l; use of less organic solvents, especially volatile organic solvents, use of less concentration aids which typically add nothing to ~ .f~llllance; etc.
As the I.V. is raised, there is a potential for odor problems. Surprisingly, some highly desirable, readily available sources of fatty acids such as tallow, possess odors that remain with the softener compounds despite the chemical and m~-~h~nical processing steps which convert the raw tallow to fini.ched active. Such sources must be deodorized, e.g., by absorption, ~ till~tion (inchl-lin ~7L.;~pillg such as steam ~L,i~hlg), etc., as is well known in the art. In addition, care must be taken to minimi7f~ contact of the reslllting fatty acyl groups to oxygen and/or bacteria by adding antioxidants, antibacterial agents, etc. The additional expense W O 97/2268~ PCT~US96/19095 and effort associated with the unsaturated fatty acyl groups is justified by thesuperior concentratability and/or performance. For example, diester quaternary ammonium salt (DEQA) Cont~ining unsaturated fatty acyl groups having an I.V.
greater than about 10 can be concentrated above about 13% without the need for additional concentration aids, especially surfactant concentration aids as discussed hereinafter.
The above softener actives derived from highly unsaturated fatty acyl groups, i.e., fatty acyl groups having a total unsaturation above about 65% by weight, do not provide any additional improvement in ~nti~t~tiC effectiveness. They may, however, be able to provide other benefits such as improved water absorbency of the fabrics. In general, an I.V. range of from about 40 to about 65 is preferred for concentratability, ma~cimi7~tion of fatty acyl sources, excellent softness, static control, etc.
Highly concentrated aqueous dispersions of these softener compounds can gel and/or thicken during low (5 ~(:~) temperature storage. Softener compounds made from only unsaturated fatty acids minimi7Ps this problem but additionally is more likely to cause malodor formation. Surprisingly, compositions from these softener compounds made from fatty acids having an I.V. of from about 5 to about25, preferably from about 10 to about 25, more preferably from about 15 to about20, and a cis/trans isomer weight ratio of from greater than about 30/70, preferably greater than about 50/50, more preferably greater than about 70/30, are storage stable at low Lelllp~dlul~ with minim~l odor formation. These cis/trans isomer weight ratios provide optimal concentratability at these I.V. ranges. In the I.V.
range above about 25, the ratio of cis to trans isomers is less important unless higher concentrations are needed. The relationship between I.V. and conce~ dldbility isdescribed he.~ ~er. For any IV, the concentration that will be stable in an aqueous cu-,l~o~ilion will depend on the criteria for stability (e.g., stable down to about 5~C; stable down to 0~C; doesn't gel; gels but recovers on hP~ting, etc.) and the other ingredients present, but the concentration that is stable can be raised by adding the conc~ntr~tion aids, described hereinafter in more detail, to achieve the desired stability.
Generally, hydrogenation of fatty acids to reduce polyunsaturation and to lower I.V. to insure good color and improve odor and odor stability leads to a high - degree of trans configuration in the molecule. The.~fole, diester compounds derived from fatty acyl groups having low I.V. values can be made by mixing fully hydrogenated fatty acid ~,vith touch hydrogenated fatty acid at a ratio which provides an I.V. of from about S to about 25. The polylln~h~r~tion content of the touch W O 97/22682 PCT~US96/19095 hardened fatty acid should be less than about 5%, preferably less than about 1%.During touch hardening the cis/trans isomer weight ratios are controlled by methods known in the art such as by optimal mixing, using specific catalysts, providing high H2 availability, etc. Touch hardened fatty acid with high cis/kans isomer weightratios is available commercially (i.e., Radiacid 406 from FINA~.
It has also been found that for good chemical stability of the diester quaternary compound in molten storage, moisture level in the raw material must be controlled and minimi7e~ preferably less than about 1% and more preferably less than about 0.5% water. Storage temperatures should be kept as low as possible and still ...~i..l;~i.. a fluid material, ideally in the range of from about 49~C to about 66~C. The optimum storage temperature for stability and fluidity depends on the specific I.V. of the fatty acid used to make the softener compound and the level/type of solvent selected. It is important to provide good molten storage stability toprovide a commercially feasible raw m~ten~l that will not degrade noticeably in the normal transportation/storage/h~n-l~ing of the material in m~nllf~cturing operations.
It will be understood that substituents R and Rl can optionally be substituted with various groups such as alkoxyl or hydroxyl groups. The preferred compounds can be considered to be diester variations of ditallow dimethyl ammonium chloride (DTDMAC), which is a widely used fabric softener. At least 80% of the softener compound, i.e., DEQA is preferably in the diester form, and from 0% to about 20%, preferably less than about 10%, more preferably less than about 5%, can be monoester, i.e., DEQA monoester (e.g., co/.l;.;..i.l~ only one -Y- Rl group).
As used herein, when the diester is specified, it will include the monoester that is nnrm~lly present in m~nllf~ctllre. For softening, under no/low d~lgent carry-over laundry conditions the ~ cel-Lage of monoester should be as low as possibre, preferably no more than about 2.5%. However, under high detel~ellt carry-over conditions, some monoester is preferred. The overall ratios of diester to monoester are from about 100:1 to about 2:1, preferably from about 50:1 to about5:1, more preferably from about 13:1 to about 8:1. Under high d~Ll~elll carry-over conditions, the di/monoester ratio is preferably about 11:1. The level of monoester present can be controlled in the m~nl-f~l~tllring of the softener compound.
In addition, since the foregoing compounds (diesters) are somewhat labile to hydrolysis, they should be h~nflled rather carefully when used to form~ te the compositions herein. For t;x~lplc, stable liquid compositions herein are form~ te~l at a pH (neat) in the range of from about 2 to about 5, preferably from about 2 to about 4.5, more preferably from about 2 to about 4. For best product odor stability, when the I.V. is greater that about 25, the neat pH is from about 2.8 to about 3.5 W O 97/22682 PCT~US96/19095 especially for lightly scented products. This appears to be true for all of the above softener compounds and is especially true for the pre~erred DEQA specified herein, i.e., having an I.V. of greater than about 20, preferably greater than about 40. The limitation is more important as I.V. increases. The pH can be adjusted by the addition of a Bronsted acid. pH ranges for making chemically stable softener compositions cont~ining diester quaternary ammonium fabric softening compounds are disclosed in U.S. Pat. No. 4,767,547, Straathof et al., issued on Aug. 30, 1988, which is incorporated herein by reference.
Examples of suitable Bronsted acids include the inorganic mineral acids, carboxylic acids, in particular the low molecular weight (C1-C5) carboxylic acids, and allcylsulfonic acids. Suitable inorganic acids include HCI, H2SO~, HNO3 and H3PO4. Suitable organic acids include formic, acetic, methylsulfonic and ethylsulfonic acid. Prer.,ll~,d acids are hydrochloric, phosphoric, and citric acids.
Liquid compositions of this invention typically contain from about 0.5% to about 80%, preferably from about 1% to about 35%, more preferably from about 4% to about 32%, of bio~legr~ ble diester qn~tem~ry ammonium softener active.
Concentrated compositions are disclosed in allowed U.S. Pat. Applic. Ser. No.
08/169,858, filed December 17, 1993, Swartley, et al., said application being incorporated herein by reference.
Particulate solid, granular.compositions of this invention typically contain from about 50% to about 95%, preferably from about 60% to about 90% of biodegradable diester ~ t~ arnmonium softener active.
The amount of fabric softening agent (fabric softener) in liquid compositions of this invention is typically from about 2% to about 50%, preferably from about 4%
to about 30%, by weight of the composition. The lower limits are amounts needed to con~ribute eLr~clive fabric softening perf~)rrn~n~e when added to laundry rinse baths in the nra~ , which is customary in home laundry practice. The higher limits are suitable for collcent~ ed products which provide the consumer with more economical usage due to a reduction of pa~ ging and distributing costs.
Fully forn~ tecl fabric softening compositions preferably contain, in addition to the hereinbefore described components, one or more of the following - ingre~lient~
Concelllldled compositions of the present invention may require organic ~ and/or inorganic co~ ;on aids to go to even higher conct;lllldlions and/or to meet higher stability standards depending on the other ingredients. Surfactant concentration aids are typically selected from the group con~i~ting of single long chain alkyl cationic surf~,t~nt~; nonionic surf~ct~ntc; arnine oxides; fatty acids; or W O 97/22682 PCT~US96/19095 mixtures thereo~, typically used at a level of from 0 to about 15% of the composition.
Inorganic viscosity/dispersibility control agents which can also act like or gm~nt the effect of the surfactant concentration aids, include water-soluble, ionizable salts which can also optionally be incorporated into the compositions of the present invention. A wide variety of ionizable salts can be used. Exarnples of suitable salts are the halides of the Group IA and IIA metals of the Periodic Table of the Element~, e.g., calcium chloride, m~ um chloride, sodium chloride, potassium bromide, and lithium chloride. The ionizable salts are particularly useful during the process of mixing the ingredients to make the compositions herein, and later to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted according to the desires of the form~ tor. Typical levels of salts used to control the composition viscosity are from about 20 to about 20,000 parts per million (ppm),preferably from about 20 to about 11,000 ppm, by weight of the composition.
Alkylene polyammoniurn salts can be incorporated into the composition to give viscosity control in addition to or in place of the water-soluble, ionizable salts above. In addition, these agents can act as scavengers, forming ion pairs with anionic dchl~,cll~ carried over from the main wash, in the rinse, and on the fabrics, and can improve softness perform~n~e These agents may stabilize the viscosity over a broader range of tem~cldlu.~, especially at low t~lllpc~dlLll~ s, cc,nl~ucd to the inorganic electrolytes.
Specific cx~llples of aL~ylene polyammonium salts include l-lysine monohydrochloride and 1,5-~i~mmoniurn 2-methyl pentane dihydrochloride.
Another optional, but ~.er~ d, ingredient is a liquid carrier. The liquid carrier employed in the instant compositions is preferably at least primarily water due to its low cost, relative availability, safety, and environmçnt~l c~.,.p;.l;hility.
The level of water in the liquid carrier is preferably at least about 50%, most preferably at least about 80%, by weight of the carrier. The level of liquid carrier is greater than about 50%, preferably greater than about 65%, more preferably greater than about 70%. Mixtures of water and low molecular weight, e.g., <about 200, organic solvent, e.g., lower alcohols such as ethanol, propanol, is~lo~ ol or butanol are useful as the carrier liquid. Low molecular weight alcohols include monohydric, dihydric (glycol, etc.) trihydric (glycerol, etc.), and higher polyhydric (polyols) alcohols.
Stabilizers can be present in the compositions of the present invention. The term "stabilizer," as used herein, includes antioxidants and reductive agents both of CA 022408l6 l998-06-l8 W O 97/22682 PCTrUS96/19095 which are well-known in the art. These agents are present at a level of from 0% to about 2%, preferably from about 0.01% to about 0.2%, more preferably from about 0.035% to about 0.1% for antioxidants, and more preferably from about 0.01% to about 0.2% for reductive agents. These assure good odor stability under long term storage conditions for the compositions and compounds stored in molten form. Theuse of antioxidants and reductive agent stabilizers is especially desirable for low scent products (low perfume).
Optionally, the compositions of the present invention can contain from 0%
to about 10%, preferably from about 0.1% to about 5%, more preferably from about0.1% to about 2%, of a soil release agent. Preferably, such a soil release agent is a polymer. Polymeric soil release agents useful in the present invention include copolymeric blocks of terephthS~I-S~te and polyethylene oxide or polypropylene oxide, and the like. These agents give additional stability to the concentrated a~ueous, liquid compositions. Therefore, their presence in such liquid compositions, even at levels which do not provide soil release benefits, is pler~ ed.
Preferred soil release agents include a copolymer having blocks of terephthS~ISIt~ and polyethylene oxide, crystS~ S~ble polyesters and polymers of the generic formula:

X-(OCH2CH2)n (0-C~O)- RI-C(O)-O-R2)U-(O-C(O)- RI-C(O)-O)-(CH2CH20)n-X

in which X can be any suitable capping group, with each X being selected from the group con~i~ting of H, and alkyl or acyl groups co..~ ;i.g from about 1 to about 4 carbon atoms, preferably methyl, n is selected for water solubility and generally is from about 6 to about 113, preferably from about 20 to about 50, and u is critical to formulation in a liquid composition having a relatively high ionic strength. There should be very little mslte~sll in which u is greater than 10. Furthermore, there should be at least 20%, preferably at least 40%, of mZlteri~l in which u ranges from about 3 to about 5.
The Rl moieties are es~erltiSIlly 1,4-phenylene moieties. As used herein, the term "the Rl moieties are ~s,sentiSIlly 1,4-phenylene moieties" refers to compounds ~ where the R~ 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. R2 can be any suitable ethylene or substituted ethylene moieties. A more complete disclosure of these highly preferred soil release agents is con~illcd in Eu~o~ean Patent Application 185,427, Gosselink, published June 25, 1986, the disclosure of which is incorporated herein by reference.

Detersive Surfactant-Detersive surfactants can be included in the compositions of the present invention. Such compositions may comprise at least 1%, preferably from about 1%
to about 99.8%, by weight of surfactant depending upon the particular surfactants used and the effects desired. In a highly preferred embodiment, the detersive surfactant comprises from about 5% to about 80% by weight of the composition.
The detersive surfactant can be nonionic, anionic, ampholytic, zwitterionic, or cationic. Mixtures of these surfactants can also be used. Preferred detergent compositions comprise anionic detersive surf~ct~ntc or mixtures of anionic surfactants with other surfa~t~nt~, especially nonionic surfactants.
Nonlimiting examples of surf~l tAnt~ useful herein include the conventional Cll-CI8 alkyl benzene sulfonates and primary, secondary and random alkyl sulfates, the Cl0-Cl8 alkyl alkoxy slllf~tes, the Cl0-C~8 alkyl polyglycosides and their co,~pollding sulfated polyglycosides, Cl2-CI8 alpha-sulfonated fatty acid esters, Cl2-Cl8 alkyl and aLt~yl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), Cl2-Cl8 betaines and sulfobetaines ("slllt~inPs"), Cl0-C~8 amine oxides, and the like. Other conventional useful surfactants are listed in standard texts.
One class of nonionic surfactant particularly useful in detergent compositions of the present invention is con{lPn~tes of ethylene oxide with a hydrophobic moiety to provide a surfactant having an average hydrophilic-lipophilic balance (HLB) in the range of from S to 17, preferably from 6 to 14, more plere~ably from 7 to 12.
The hydrophobic (lipophilic) moiety may be aliphatic or aromatic in nature. The length of the polyoxyethylene group which is confl~n~e~l with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hy~hobic elements.
Especially ~ier~ d nonionic surfactants of this type are the C9-C15 primary alcohol ethoxylates cu~ g 3-8 moles of ethylene oxide per mole of alcohol, particularly the C14-C l5 primary alcohols cont~inin~ 6-8 moles of ethylene oxide per mole of alcohol, the Cl2-Cls primary alcohols cont~ining 3-5 moles of ethylene oxide per mole of alcohol, and mixtures thereof.
Another suitable class of nonionic surfactants compri.~es the polyhydroxy fatty acid amides of the formula:
-W O 97/22682 PCT~US96/19095 R2C(03n(RI)Z
wherein: Rl is H, C 1 -C8 hydrocarbyl, 2-hydroxyethyl, 2-hydroxypropyl, or a mixture thereof, preferably Cl-C4 alkyl, more preferably Cl or C2 alkyl, most preferably Cl aLlcyl (i.e., methyl); and R2 is a C5-C32 hydrocarbyl moiety, preferably straight chain C7-C19 alkyl or alkenyl, more preferably straight chain C9-C17 alkyl or alkenyl, most preferably straight chain Cll-C19 alkyl or alkenyl, or mixture thereof; and Z is a polyhydroxyhydrocarbyl moiety having a linear hydrocarbyl chain with at least 2 (in the case of glyceraldehyde) or at least 3 hydroxyls (in the case of other reducing sugars) directly connected to the chain, or an alkoxylated derivative (preferably ethoxylated or propoxylated~ thereof. Z preferably will be derived from a reducing sugar in a reductive arnination reaction, more preferably Z
is a glycityl moiety. Suitable reducing sugars include glucose, fructose, maltose, lactose, galactose, rnannose, and xylose, as well as glyceraldehyde. As raw materials, high dextrose corn syrup, high fructose corn syrup, and high maltose corn syrup can be utilized as well as the individual sugars listed above. These corn syrups may yield a mix of sugar components for Z. It should be understood that it is by no means intenr~e-1 to exclude other suitable raw m~teri~l~. Z preferably will be selected from the group consisting of -CH2-(CHOH)n-CH20H, -CH(CH2OH)-(CHOH)n- 1 -CH2OH, -CH2-(CHOH)2(CHOR2)(CHOH)-CH2OH, where n is an integer from 1 to 5, inclusive, and R2 is H or a cyclic mono- or poly- saccharide, and aLkoxylated derivatives thereof. Most ~lc~ d are glycityls wherein n is 4, particularly -CH2-(CHOH)4-CH2OH.

Builders -De~ ;el1t builders can optionally be included in the compositions herein to assist in controlling nnineral hardness. Inorganic as well as organic builders can be used. Builders are typically used in fabric l~l-n-l~ring compositions to assist in the removal of particulate soi}s.
The level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present, the compositions will typically Comrri~ce at least about 1% builder. Liquid forrnulations typically ~ comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular formulations typically comprise from about ~ 10% to about 80%, more typically from about 15% to about 50% by weight, of the d~ g~ builder. Lower or higher levels of builder, however, are not meant to be exçlll~le~l W O 97/22682 PCT~US96/19095 Inorganic or P-cont~;ning detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulph~tec, and aluminos;licates. However, non-phosphate builders are required in some locales. I.llpol Lal1tly, the compositions herein function surprisingly well even in the presence of the so-called "weak" builders (as eo,llpar. d with phosphates) such as citrate, or in the so-called "underbuilt" situation that may occur with zeolite or layered silicate builders.
Examples of silicate builders are the alkali metal silicates, particularly thosehaving a SiO2:Na20 ratio in the range 1.6:1 to 3.2:1 and layered silicates, such as the layered sodium silicates described in U.S. Patent 4,664,839, issued May 12, 1987 to H. P. ~ieck. NaSKS-6 is the tr~<lem~rk for a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as "SKS-6"). Unlike zeolite builders, the Na SKS-6 silicate builder does not contain alllmimlm NaSKS-6 has the delta-Na2SiO5 morphology form of layered silicate. It can be prepared by methods such as thosedescribed in German DE-A-3,417,649 and DE-A-3,742,043. SKS-6 is a highly preferred layered silicate for use herein, but other such layered cili~te~, such as those having the general forrnula NaMSixO2x+1.yH20 wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a nurnber from O to 20, preferably O can be used herein. Various other layered .~ilicat~s from Hoechst include NaSKS-S, NaSKS-7 and NaSKS-11, as the alpha, beta and gamma forms.
As noted above, the delta-Na2SiOS (NaSKS-6 form) is most ~lef~ lled for use herein.
Other silicates may also be useful such as for exarnple magnesium silicate, which can serve as a C~iS~t;llillg agent in granular formulations, as a stabilizing agent for oxygen bleaches, and as a component of suds control systems.
Examples of carbonate builders are the ~Ik~line earth and alkali metal c~l,ol1dles as disclosed in German Patent Application No. 2,321,001 published onNovember 15, 1973.
mint cilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in most ~ llly m~rk~te~l heavy duty granular dt;te.~ell~ compositions, and can also be a significant builder ingredient in liquid d~ ellL formulations. Alllminosilicate builders include those having the empirical form~
Mz(zAlO2)y~ ~XH2O
wherein z and y are integers of at least 6, the molar ratio of z to y is in the range from 1.0 to about 0.5, and x is an integer from about 15 to about 264.

VVO 97/22682 PCT~US96/19095 Useful aluminosilicate ion exchange materials are cornrnercially available.
These aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring aluminosilicates or synthetically derived. A method for producing alurninosilicate ion exchange m~teri~l~ is disclosed in U.S. Patent 3,985,669, Krummel, et al, issued October 12, 1976. Preferred synthetic crystalline aluminosilicate ion exchange m~teri~l~ useful herein are available under the desi~n~tions Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. In an especially ~ f~ d embodiment, the crystalline aluminosilicate ion exchange m~teri~l has the formula:
Nal2r(AI02)~2(SiO2),2] .xH2o wherein x is from about 20 to about 30, especially about 27. This material is known as Zeolite A. Dehydrated zeolites (x = 0 - 10) may also be used herein. Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in ~ t.?r.
Organic d~ elll builders suitable for the purposes of the present invention include, but are not restricted to, a wide variety of polycarboxylate compounds. As used herein, "polyc~1,02~ylate" refers to compounds having a plurality of carboxylate groups, ~l.,r~.ably at least 3 carboxylates. Polycarboxylate builder can generally be added to the composition in acid forrn, but can also be added in the form of a neutralized salt. When utilized in salt form, alkali metals, such as sodium, pU~ iu~ and lithiurn, or alkanolammonium salts are ~ierc,l~d.
Included among the polycarboxylate builders are a variety of categories of useful m~t.?ri~l~ One illl~ol~ category of polycarboxylate builders encomp~eq the ether polycarboxylates, including oxydisuccinale, as disclosed in Berg, U.S.Patent 3,128,287, issued April 7, 1964, and Lamberti et al, U.S. Patent 3,635,830, issued January 18, 1972. See also "TMS/TDS" builders of U.S. Patent 4,663,071, issued to Bush et al, on May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S.
Patents 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903.
Other useful d~tel~ellcy builders include the ether hydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1, 3, 5-trihydroxy benzene-2, 4, 6-trisulphonic acid, and carboxymethyloxysuccinic acid,the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethyl~?n~ mine tetraacetic acid and nitrilotriacetic acid, as well as - polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof.

W O 97/22682 PCT~US96/19095 Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent for nulations due to their availability from renewable resources and their biodegradability. Citrates can also be used in granular compositions, especially in combination with zeolite and/or layered silicate builders. Oxydisuccinates are also especially useful in such compositions and combinations.
Also suitable in the compositions of the present invention are the 3,3-dicar-boxy-4-oxa-1,6-hexanedioates and the related compounds disclosed in U.S. Patent 4,566,984, Bush, issued January 28, 1986. Useful succinic acid builders include the C5-C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-p~nt~(lecenylsuccinate, and the like.
Lauryls~-ccin~te~ are the ~ler...ed builders of this group, and are described inEuropean Patent Application 86200690.5/0,200,263, published November 5, 1986.
Other suitable polycarboxylates are disclosed in U.S. Patent 4,144,226, Crutchfield et al, issued March 137 1979 and in U.S. Patent 3,308,067, Diehl, issued March 7, 1967. See also Diehl U.S. Patent 3,723,322.
Fatty acids, e.g., Cl2-CI8 monocarboxylic acids, can also be inco~porated into the compositions alone, or in combination with the aforesaid builders, especially citrate and/or the succinate builders, to provide additional builder activity. Such use of fatty acids will generally result in a tlimimltion of sll~cin~, which should be taken into account by the formnl~tor.
In si~ tion~ where phosphorus-based builders can be used, and especially in the formulation of bars used for hand-l~lln(l~ring operations, the various alkali metal phosphsltee such as the well-known sodium tripolyphosph~t~s, sodium pyrophosphate and sodium orthophosphate can be used. Phosphonate builders such as ethane-l-hydroxy-l,l-diphosphonate and other known phosphonates (see, for example, U.S. Patents 3,159,581; 3,213,030; 3,422,021; 3,400,148 and 3,422,137 can also be used.

Enzymes -Enzymes can be included in the compositions of the present invention for a - variety of purposes, including removal of protein-based, carbohydrate-based, or triglyceride-based stains from surfaces such as textiles or dishes, for the prevention of refugee dye transfer, for example in laundering, and for fabric restoration Suitable enzymes include proteases, arnylases, lipases, cell~ ee~, peroxi~ e~, and mixtures thereof of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. Preferred selections are influenced by factors such as pH-activity -W O 97/22682 PCT~US96/19095 and/or stability optima, therrnostability, and stability to active detergents, builders and the like. In this respect bacterial or fungal enzymes are preferred, such asbacterial amylases and proteases, and fungal cellulases.
"Detersive enzyme", as used herein, means any enzyme having a cleaning, stain removing or otherwise beneficial effect in a laundry, hard surface cleaning or personal care detergent composition. Preferred detersive enzymes are hydrolases such as proteases, amylases and lipases. Preferred enzymes for laundry purposes inc}ude, but are not limited to, proteases, cellulases, lipases and peroxidases. Highly preferred for automatic dishwashing are amylases and/or proteases, including both current con~ elcially available types and improved types which, though more and more bleach compatible though s~-~cPseive improvements, have a r~.n~ i"g degree of bleach deactivation susceptibility.
Enzymes are normally incorporated into detergent or detergent additive compositions at levels sufficient to provide a "cleaning-effective amount". The terrn "cleaning effective amount" refers to any amount capable of producing a cle~ning, stain removal, soil removal, whitening, deodorizing, or freshness improving effect on substrates such as fabrics, dishware and the lilce. In practical terms for current commercial ~n~cl~a,dLions, typical amounts are up to about 5 mg by weight, more typically û.01 mg to 3 mg, of active enzyme per gram of the detergent composition.
Stated otherwise, the compositions herein will typically comprise from 0.001% to5%, preferably 0.01%-1% by weight of a commercial enzyme I,le~d~ion. Protease enzymes are usually present in such commercial ~lc~ dLions at levels sufficient to provide from 0.005 to 0.1 Anson units (AU) of activity per gram of composition.
For certain d-cl~lgellls, such as in automatic dishwashing, it may be desirable to il~iredse the active enzyme content of the commercial plep~aLion in order to minim~7e the total amount of non-catalytically active materials and thereby improve spotting/filming or other end-results. Higher active levels may also be desirable in highly conce~ aled ~lc;l~rgel-l forrnulations.
Suitable ~mrles of proteases are the subtilisins which are obtained from particular strains of B. subtilis and B. licheniformis. One suitable protease isobtained from a strain of Bacillus, having mz1xi,.,~ . activity throughout the pH

The enzyme stabilizing system can be any stabilizing system which is compatible with the detersive enzyme. Such a system may be inherently provided by other formulation actives, or be added separately, e.g., by the formulator or by a m~nllf~turer of detergent-ready enzymes. Such stabilizing systems can, for example, comprise calcium ion, boric acid, propylene glycol, short chain carboxylic acids, boronic acids, and mixtures thereof, and are ~lesigned to address different stabilizatlon problems depending on the type and physical form of the detergent composlhon.
One stabilizing approach is the use of water-soluble sources of calcium and/or m~nPcium ions in the finish~d compositions which provide such ions to the enzymes. Calciurn ions are generally more effective than m~n~sium ions and are preferred herein if only one type of cation is being used. Typical detergent cornpositions, especially liquids, will comprise from about 1 to about 30, preferably from about 2 to about 20, more ~l~lably from about 8 to about 12 millimoles of calcium ion per liter of fini~hed de~ ,e.lt composition, though variation is possible depending on factors incll-llin~ the multiplicity, type and levels of enzymes incorporated. Preferably water-soluble calcium or m~gneeium salts are employed, including for exarnple calcium chloride, calcium hydroxide, calcium for,nate, calcium malate, calcium maleate, calcium hydroxide and calciurn acetate; more generally, calcium sulfate or m~n~cium salts col,~sponding to the exemplified calcium salts can be used. Further increased levels of Calcium and/or Magnesiurnmay of course be useful, for example for promoting the grease-cutting action of certain types of surfactant.
Another stabilizing approach is by use of borate species. See Severson, U.S
4,537,706. Borate stabilizers, when used, can be at levels of up to 10% or more of the composition though more typically, levels of up to about 3% by weight of boric acid or other borate compounds such as borax or orthoborate are suitable for liquid dt:L~lg~ use. Substituted boric acids such as phenylboronic acid, butaneboronic acid, p-bromo~he,~lboronic acid or the like can be used in place of boric acid and reduced levels of total boron in d~lel~ l compositions may be possible though the use of such sl-hstitllte-l boron derivatives.

WO 97/Z268~ PCT/US96/19095 Stabilizing systems of certain cleaning compositions, for exarnple automatic dish washing compositions, may further comprise from 0 to about 10%, preferably from about 0.01% to about 6% by weight, of chlorine bleach scavengers, added to prevent chlorine bleach species present in many water supplies from ~tt~king andinactivating the enzymes, especially under alkaline conditions. While chlorine levels in water may be small, typically in the range from about 0.5 ppm to about1.75 ppm, the available chlorine in the total volume of water that comes in contact with the enzyme, for example during dish- or fabric-washing, can be relatively large;
accordingly, enzyme stability to chlorine in-use is sometimes problematic. Sinceperborate or percarbonate, which have the ability to react with chlorine bleach, may present in certain of the instant compositions in amounts accounted for separately from the stabilizing system, the use of additional stabilizers against chlorine, may, most generally, not be çSs~?nt~ though improved results may be obtainable from their use. Suitable chlorine scavenger anions are widely known and readily available, and, if used, can be salts cont~;ning ammonium cations with sulfite, bi~lllfi~e, thiosulfite, thiosulfate, iodide, etc. Antioxidants such as carbamate, ascorbate, etc., organic amines such as ethylen~ minetetracetic acid (EDTA) or alkali metal salt thereof, monoethanolamine ~MEA), and mixtures thereof can likewise be used. Likewise, special enzyme inhibition systems can be incol~oldled such that dirr~ l enzymes have maximum compatibility. Other conventional scavengers such as bisulfate, nitrate, chloride, sources of hydrogen peroxide such as sodium perborate tetrahydrate, sodium perborate monohydrate and sodium pelcalbo.lal~, as well as phosphate, con~l~n~e~l phosphate, acetate, ben70~te, citrate, formate, lactate, malate, tartrate, salicylate, etc., and mixtures thereof can be used if desired. In general, since the chlorine scavenger function can be ~ rolllled by ingredlents separately listed under better recognized functions, (e.g., hydrogenperoxide sources), there is no absolute requirement to add a separate chlorine scavenger unless a compound pclrolllling that function to the desired extent is absent from an enzyme-co..~ g embodiment of the invention; even then, the scavenger is added only for optimum results. Moreover, the form~ tor will exercise a ch~ t's normal skill in avoiding the use of any enzyrne scavenger or stabilizer - which is majorly incompatible, as formul~tell~ with other reactive ingredients, if used. In relation to the use of ammoniurn salts, such salts can be simply ~1mixe(1 with the d~ gclll composition but are prone to adsorb water and/or liberate ammonia during storage. Accordingly, such materials, if present, are desirably protectedL in a particle such as that described in US 4,652,392, Baginski et al.

W O 97/22682 PCT~US96/19095 Other Optional Ingredients Other ~ref~lled optional ingredients include polymeric soil release agents, materials effective for inhibiting the transfer of dyes from one fabric to another during the cleaning process (i.e., dye transfer inhibiting agents), polymeric dispersing agents, suds suppressors, optical brighteners or other brightenin~ orwhitening agents, chelating agents, fabric softening clay, anti-static agents, other active ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solvents for liquid formulations, solid fillers for bar compositions" bacteriocides, colorants, perfumes, preservatives, opacifiers, stabilizers such as guar gurn and polyethylene glycol, anti-shrinkage agents, anti-wrinkle agents, fabric crisping agents, spotting agents, germicides, fungicides, anti-corrosion agents, and the like.
Liquid compositions can contain water and other solvents as carriers. L4w molecular weight primary or secondary alcohols exemplified by methanol, ethanol,propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfactant, but polyols such as those Cont~ining from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanediol) can also be used. The compositions may contain from 5% to 90%, typically 10% to 50% of such carriers.

Process Granular compositions can be p~ ed, for exarnple, by spray-drying (final product density about 520 g/l) or agglomerating (final product density above about 600 g/l) the Base Granule. The l~".~ g dry ingredients can then be ~f~mixecl in gr~mll~r or powder form with the Base Granule, for example in a rotary mixing drum, and the liquid ingredients (e.g., nonionic surfactant and perfiune) can besprayed on.
The gr~n~ r fabric softening compositions of the present invention can be formed by ~uing a melt, solidifying it by cooling, and then grinding and sievingto the desired size. In a three-component mixture, e.g. nonionic surfactant, single-long-chain cationic, and DEQA, it is more pl~fe~led, when forming the granules, to pre-mix the nonionic snrf~t~nt and the more soluble single-long-chain alkyl cationic compound before mixing in a melt of the diester ~mmonillm çqt;on;c compound.
It is highly preferred that the primary particles of the granules have a meter of from about 50 to about 1,000, preferably from about 50 to about 400, more preferably from about 50 to about 200, microns. The granules can comprise smaller and larger particles, but preferably from about 85% to about 95%, more ~ ~ = .

preferably from about 95% to about 100%, are within the indicated ranges. Smaller and larger particles do not provide optimum emulsions/dispersions when added to water. Other methods of preparing the primary particles can be used including spray cooling of the melt. The primary particles can be agglomerated to form a dust-free, non-tacky, free-flowing powder. The agglomeration can take place in aconventional agglomeration unit (i.e., Zig-Zag Blender, Lodige) by means of a water-soluble binder. Exarnples of water-soluble binders useful in the above agglomeration process include glycerol, polyethylene glycols, polymers such as PVA, polyacrylates, and natural polymers such as sugars.
The flowability of the granules can be improved by treating the surface of the granules with flow improvers such as clay, silica or zeolite ' particles, water-soluble inorganic salts, starch, etc.

Method of Use In use, water can be added to the particulate, solid, granular compositions to form dilute or concentrated liquid softener compositions for later addition to the rinse cycle of the laundry process with a concentration of said biodegradable cationic softening compound of from about 0.5% to about 50%, preferably from about 1% to about 35%, more preferably from about 4% to about 32%,. The particulate, rinse-added solid composition ~1) can also be used directly in the rinse bath to provide adequate usage concentration (e.g., from about 10 to about 1,000ppm, preferably from about 50 to about 500 ppm, of total softener active ingredient). The liquid compositions can be added to the rinse to provide the same usage concc;~ d~ions.
The water t~ cldl~ for l"~p~dlion should be from about 20~C to about 90~C, preferably from about 25~C to about 80~C. Single-long-chain alkyl cationic~u,rd~ as the viscosity/dispersibility modifier at a level of from 0% to about 15%, preferably from about 3% to about 15%, more preferably from about 5% to about 15%, by weight of the composition, are ~.~fell~d for the solid composition.
Nonionic surf~ct~nt~ at a level of from about 5% to about 20%, preferably from about 8% to about 15%, as well as mixtures of these agents can also serve effectively as the viscosity/dispersibility modifier.
The em~ ified/dispersed particles, formed when the said granules are added to water to form a~ueous con~pntr~t~ typically have an average particle size of less than about 10 microns, preferably less than about 2 microns, and more plef~ldblyfrom about 0.2 to about 2 microns, in order that effective deposition onto fabrics is achieved. The term "average particle size," in the context of this specification, W O 97/22682 PCT~US96/19095 means a number average particle size~ i.e., more than 50% of the particles have a diarneter less than the specified size.
Particle size for the emulsified/dispersed particles is determined using, e.g., a Malvern particle size analyzer.
If the composition of the present invention includes a detergent or surfactant, the compositions herein will preferably be formulated such that, during use in aqueous cleaning operations, the wash water will have a pH of between about 6.5 and about 11, preferably between about 7.5 and 10.5. Laundry products are typically at pH 9-11. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art.
