Description

W o 97/44433 PCTnUS97/08373 DETERGENT COMPOSITION

Te~h~-;c~l Field S
The present invention relates to a deler~,ent co-1-posilion compricing a peroxygen bleach, a bleach catalyst a non-AQA s~lrf~r-t~nt and a bis-alkoxylated qua~e ammonium ~bis-AQA) c~tio~i~ surfactant.

R~ .nd ~o the Invention The formulation of laundry det~ ,enls and other cl~nin~ co---pos;lions ~l~e~ a conci-lP-~hle ~'h~llPngP, sinc~ modern c~"-po~,ilions are required to remove a variety of soils and stains from diverse substrates. Thus, laundry det~ , hard surface 15 ~lP~nPrs, ch~mI)oos and other ~nal cl~n~ P colnposi~;onc~ hand dishwashing dele.~,enLs and dete1~,ent compositions suitable for use in ?~ v.~ ;C disl,w~sl,c;.~ all require the proper sPl~tis)~ and co",binalion of ingredients in order to function effectively. In ge~ P-~l, such del~.gelll co...~s;l;onc will contain one or more types of surf~-t~ntc which are ~1~Pci~n~Pd to loosen and remove dirre~nl types of soils and stains.
20 While a review of the lite.~u~ would seem to in~ tP that a wide sPl~tic)n oiFsurf~t~ntc and surfactant co"~binalions are available to the d~ ,ent m~mlf~ rer, ~e reality is that many such ingredients are cpeci~lty ch~.mjr~l.c which are not suitable in low unit cost items such as home-use laundry dete;~enls. The fact remains that most such home-use products such as laundry deLelge.,t~ still mainly comprise one or more of 25 the convention~l ellluAylat~d noninnir and/or s ~lfZ~t~d or sulfonated anionic S~1 r~
~ u111ably due to ec~nomic con~ ;ons and the need to formulate co~ ~s;l;ons which function ~ ly well with a variety of soils and stains and a variety offabrics.

30 The quick and effi~ nt removal of dirl~e-~l types of soils and stains such as body soils, greasy/oily soils and certain food stains, can be probl~m~ic. Such soils comprise a 11liAIUl~ of hydrophobic t~iglycericles, lipids, complex poly~ch~rides, ino,E;anic salts and protein~C~Qus matter and are thus notoriously difficult to remove. Low levels of hyd1ullhobic soils and residual stains often remain on the surface of the fabric after 35 washing. Successive washing and wearing coupled with limited hydrophobic soil removal in the wash cumlin~tes in a build up of residual soil and stain which further entraps wo 97/44n3 PCT/U$97/08373 particluate dirt leading to fabric yellowing. Eventually the fabric takes on a dingy appearance which is perceived as unwearable and discarded by the col~ulller.

The literature suggests that various nitrogen-cont~ining cationic surf~t~ntc would be useful 5 in a variety of cleaning compositions. Such materials, typically in the form of amino-, amido-, or quatemalr ammonium or imif~ olinium compounds, are often deci~n.o~l for specialty use. For example, various amino and quaternary ammonium surfactants have been suggested for use in shampoo compositions and are said to provide cocm~ti~ be~
to hair. Other nitrogen-cont~inin~ surf~t~nt~ are used in some laundry de~ .lLs to 10 provide a fabric SO~ g and anti-static benefit. For the most part, however, the co...~ ~ial use of such materials has been limited by the ~iffir111ty encou~ cd in the large scale m~mlf~ re of such compounds. An additional lirnitation has been the potential precip~tion of anionic active colnL)ollcll~, of the deL~.ge.lL composition occasioned by their ionic interaction with cationic surf~t~ntc. The aforementioned nonionic and anionic 15 ~ulr~ remain the maior ~,ulr~cL~L components in today's laundry compositi-)nc It has now been discovered that certain bis-alkoxylated 4u~t~ aly ammonium (bis-AQA) colll~uullds can be used in various delLI~ellL compositions to boost d~t~g~,.l;y ~r~ lce on a variety of soil and stain types, particularly the hydrophobic soil types, cc ~ lollly 20 encountered. Unexpectedly, it has now been discovered that compositions co-~ g bis-AQA surf~ct~ntc, peroxygen bleach and a metal-cont~ining bleach catalyst deliver superior c1e~ning and w1.;~ P-cs ~u~ ce versus products c~ ;..;n~ the technologies alone.
The bis-AQA ~,ulr~ A~, of the present invention provide ~,~sl;.-.l;~1 benefits to ~e 25 for~m~1~tor, over CAI;~ ' surf~rf~ntc previously known. For example, ~e bis-AQA
surfactants used herein provide n ~rkt~(1 impro~enlc:lll in cl~nin~ of "e~ greasy/oily lly~hvyhobic soils regularly encw~ r~. Moreover, ~e bis-AQA surf~t~ntc are colllyalil)le with anionic ~u~ ntc commonly used in de~ compositions such as aLkyl sulfate and aLIcyl l~l~ze.le sulfonate; incompatability with anionic eol~onellL~ of the 30 dctelg~ composition has commonly been the li...i~ g factor in the use of c~tionir surfactants previously known. Low levels (as low as 3 ppm in the laundering liquor) of bis-AQA surf~ t~ntc gives rise to the benefits described herein. Bis-AQA su~f~rt~ntc can be form~ ted over a broad pH range from 5 to 12. The bis-AQA :iUll~CI;1lllx can be p~ d as 30% (wt.) solutions which are pumpable, and ~ Ol., easy to handle in a 3~ m~m1f~ctl1ring plant. Bis-AQA :~ull;~ with degrees of ethoxylation above 5 are _ WO 97/44433 . PC~US97~08373 sometimes present in a liquid form and can Lll~icfole be provided as 100% neat rnaterials.
In addition to their beneficial h~n~lling plu~ellies, the availability of bis-AQA surfactants as highly concentrated solutions provides a sl-bst~ntiAl economic advantage in transportation costs. The bis-AQA surfart~nt~ are also cnlnpAtible with various ~ fullle ingredients, S unlike some cationic surfA~t~nt~ known in ~e art.

Bleach catalysts (characterized by the presence of at least one transition metal atom) hllelacL with peroxide b~eaellin~ species to form very powerful hydrophilic bleArll~os.
These bleaches deliver strong b ellerlLs on colored hydrophilic stains and hydlul)l~ilic 10 e~e.~ddy soils (i.e., socks). Historical use of bleach catalysts was made ~1im~ult bec~ùse of conrern~ r~ga~ fabric damage. It has now been found that fabric damage caused by using a ~ se catalyst, known to cause fabric tl~m~e, can be much reduced when the d~L~ llL composition conl~lisi~s a bis-AQA cationic ~ulra~;L~IlL. It is proposed that these cationics adsorb onto fabrics, motlifin~ the surface charge of the fabric and 15 ~otelltially ion-pairing with the acli~.tt d catalyst to ..,;..;...i,~ or prevent fabric damage.

It is believed that the greasy/oily soils are effectively solubilized by bis-AQA, Lll~lcl,y allowing access of the hydrophilic catalyst bleach to the colour bodies in the soil (e.g.
c~lLlalJ~ed pi~m~nt.c) resl~lting in improved soil decolouration. The ability of the 20 compositions described herein to clean both hydrophilic and hydophobic soils results in ~u~lior cle~nin~ and wl.i~ c~ mAi..t. ,~A~re und Art U.S. Patent 5,441,541, issued August 15, 1995, to A.

S~ y ofthe Invention ~ The present invention provides a composition comprising or prepared by c~ bi,~ing a peroxygen bleach, a bleach catalyst a non-AQA surfactant and an effel;~ivt; amount of a bis-al~oxylated ~luat~ / ammonium (bis-AQA) cationic surfactant of the formula:

W 097/44433 PCTrUS97/08373 R~ /AP X--R2/ AqR

Whclcll~ Rl iS a linear, branced or substihlt.o~ Cg-Clg aLkyl, aL~cenyl, aryl, aLkaryl, ether or glycityl ether moiety, R2 is a Cl-C3 alkyl moiety, R3 and R4 can vary in-lepen-lPntly and are 5 selected from hydrogen, methyl and ethyl, X is an anion, and A and A' can varyindependently and are each Cl-C4 alkoxy, p and q can vary indepen~1~ntly and are hllc~ crs of from 1 to 30.

D~ D~r_l ,uti~ n of the Invention Pçroxygen Ble~cilin~ Agent The dc~gcllL compositions herein c~ll~lise a peroxygen blea~ agent. Such b~ chir~
agents are typically present at levels of from 1% to 30%, more typically from 5% to 20%, of the dclcUgc~lL composition, especi~lly for fabric laundering.

Plcrel-~d peroxygen bleaches are perhydrate bleaches. The perhydrate bleach is normally il~col~ulaled in the form of the perhydrate salt, especially the sodium salt, at a level of from 1% to 40% by weight, more ~lcr~lably from 2% to 30% by weight and most preferably from 5 % to 25 % by weight of the compositions.

Although the p~.hydlale bleach itself has some bleaclling capability, a su~- liul bleach exists in the peracid formed as a product of the reaction between the hydrogen peroxide released by the ptlllydl~Lc and a bleach acLi~a~o~ cÇol.llcd peracids are also envisaged as a ~lef~llcd pelu~y~ell blraching species.

Examples of suitable perhydrate salts include perborate, ~l.;~l,onate, perphosphate, persulfate and persilicate salts. The ~cr~.led perhydrate salts are normally the aLIcali metal salts. The ~,llydl~tc salt may be inrl~l-le~l as the crystalline solid without additional ~lo~cLion. For certain perhydrate salts however, the ~lcrc~lcd executiûns ûf such granu}ar WO 97/44433 ~c~nus97/08373 compositions utilize a coated form of the material which provides better storage stability for the perhydrate salt in the granular product.

Sodium perborate can be in the form of the monohydrate of nominal formula NaBO2H2O2 or the tetrahydrate NaBO2H2O2.3H2O.

ALkali metal percarbonates, particularly sodium percarbonate are p~ .,d perhydrates for inrl~ iQn in compositions in accordance with the invention. ~so~ lm ~elcall,ol~ate is an addition compound having a formula corresponding to 2Na2CO3.3H2O2, and is available colllmel.;ially as a crystalline solid. Sodium pel-;all~onate, being a hydrogen peroxide addition co,l,l)uu,1d tends on dissolution to release the hydrogen peroxide ~uite rapidly which can increase the tçntl~n-~y for loc~ e~l high bleach concellLldtions to arise. The pcl~albo~ L is most preferably incolpo,aLed into such compositions in a coated form which provides in-product stability.
A suitable coating material providing in product stability colllplises mixed salt of a water soluble aLkali metal sulphate and c~bollale. Such co~ting~ together with coating processes have previously been desclilJcd in GB-1,466,799, granted to Interox on 9th March 1977.
The weight ratio of the mixed salt coating material to ~ ;a bonate lies in the range from 1 : 200 to 1: 4, more ~lc;Ç~ably from 1: 99 to 1: 9, and most p lcÇ~,.dbly from 1: 49 to 1:
19. Preferably, the mixed salt is of sodium sulrh~te and sodium CalLOl~ale which has the general formula Na2SO4.n.Na2CO3 wlle~ n is from 0.1 to 3, preferably n is from 0.3 to 1.0 and most preferably n is from 0.2 to 0.5.

Other co~tin~ which contain silicate (alone or with borate salts or boric acids or other inol2~d~ics), waxes, oils, fatty soaps can also be used advantageously within the present invention.

A preferred ~,e.~;a.l,ondte bleach colll~lises dry particles having an average particle size in the range from 500 llliclullleters to 1,000 micro,l,~Lers, not more than 10% by weight of said particles being smaller than 200 ll~icrollleters and not more than 10% by weight of said ~ particles being larger than 1,250 micl~l,.,t~

Another suitable ble~ching agent which can be used without r~ ;lion enco...~ ses35 percarboxylic acid ble~chin~ agents and salts thereof. Suitable examples of this class of W O 97/44433 PCT~US97/0~373 agents include m~gn~sium monoperoxyphth~l~t~ hexahydrate, the magnesium salt of meta-chloro perbenzoic acid, 4-nonylamino4-oxoperoxybutyric acid and diperoxydo~ler~ne~i- ic acid. Such bie~hin~ agents are disclosed in U.S. Patent 4,483,781, Hartman, issued November 20, 1984, U.S. Patent Application 740,446, Burns et al, hled June 3, 1985, European Patent Application 0,133,354, Banks et al, published re~ualy 20, 1985, and U.S. Patent 4,412,934, Chung et al, issued November 1, 1983. Highly plercll~d blea~hing agents also include 6-nonylamino-6-oxopero~yc~lJ,oic acid as described in U.S.
Patent 4,634,551, issued January 6, 1987 to Burns et al. Potassium pero~y,llono~ lfate is another inorganic perhydrate salt of utility in the compositions herein.
Mixtures of ble~rlling agents are also envisaged.

Bleach Catalvst 15 The dch.~cllL compositions desclil,ed herein co,l,p,ise as an e~ l component a bleach catalyst. The catalysts are cs-lnm( nly present in e~ l"ely low levels in product, preferably from 0.001 % to 5 % by weight, more plere lably from 0.01 % to 2%, most preferably from 0.05% to 1%. Preferably the bleach catalyst is a metal-cont~inin~, more preferably a transition metal-cont~inin~ bleach catalyst. The ~l~,fcllcd transition metal~o..l;~ bleach catalysts are 20 ...~l~g~ sc or cobalt-cont~inin~ bleach catalysts.

A suitable type of bleach catalyst is a catalyst con,l)~isil~g a heavy metal cation of defined bleach catalytic activity, such as copper, iron cations, an auxiliary metal cation having little or no bleach catalytic activity, such as zinc or ~ .. cations, and a seql~estrant having defined 25 stability cs.~ .lc for the catalytic and auxiiiary metal cations, particularly ethyl~ ;..- t~ aac~lic acid, ethyle~ r.~ a (methylenephosphonic acid) and water-soluble salts thereof. Such catalysts are disclosed in U.S. Pat. 4,430,243.

P~,rclled t~rpes of bleach catalysts include the ...~ se-based complexes disclosed in U.S.
Pat. 5,246,621 and U.S. Pat. 5,244,594. I~cr~,~rcd examples of these catalysts include MnIV2(u-0)3(1,4,7-L~Ic~,yl-1,4,7-triazacyclononane)2-(PF6)2, Mnm2(u-O)l(u-OAc)2(1,4,7-Llill,~Lllyl-1,4,7-triazacyclononane)2-(C104)2, MnIV4(u-0)6(1,4,7-Llia acyclononane)4-(C104)2, MnmMnIV4(u-O)l(u-OAc)2 (1,4,7-LlilncLl~yl-1,4,7-triazacyclonol~,e)2-(ClO4)3, and ~ Lures thereof. Others are described in Eulo~call patent application public~tion no. ~49,272. Other ligands suitable for use herein include 1,~,9-WO 97/44433 PCT~US97fO8373 trimethyl-1,5,9-triazacyclododecane, 2-methyl-1,4,7-triazacyclononane, 2-methyl-1,4,7-triazacyclononane, 1,2,4,7-tetramethyl-1,4,7-triazacyclononane, and mixtures thereof.

The bleach catalysts useful in the compositions herein may also be selected as apll.~,iale for the present invention. For examples of suitable bleach catalysts see U.S. Pat. 4,246,612 and U.S. Pat. 5,227,084. See also U.S. Pat. 5,194,416 which teaches mononuclear ~ kse (IV) complexes such as Mn(l~4~7-trimethyl-l~4~7-lli3zacyclononane)(ocH3)3-(pF63.
Still another type of bleach catalyst, as disclosed in U.S. Pat. 5,114,606, is a water-soluble 10 complex of m~ng~n~se (III), and/or (IV) with a ligand which is a non~arboxylate polyhydroxy co.~,puund having at least three co~se~;uli~e C-OH groups. ~,r~ ,d ligands include sorbitol, iditol, dulsitol, ~-.~ ol, xylithol, arabitol, adonitol, meso e.yllllilol, meso-inositol, lactose, and llli~Lules thereof.

15 U.S. Pat. 5,114,611 teaches a bleach catalyst co~ isin~ a complex of transition metals, inr!~ ng Mn, Co, Fe, or Cu, with an non-(macro)-cyclic ligand. Said ligands are of the forrnula:

R1_N=C-B-C=N-R4 W11C1CL1I Rl, R2, R3, and R4 can each be selPcte(l from H, substituted aLkyl and ary} groups such that each R1-N=C-R2 and R3-C=N-R4 form a five or six-membered ring. Said ring can further be sub~ d. B is a bridging group se!ected from O, S. CR5R6, NR7 and C=O,wl~.ein R5, R6, and R7 can each be H, aLkyl, or aryl groups, inr~ iin~ s~ sl or 25 ~ d groups. Preferred ligands include pyridine, pyridazine, pyrimi-linP, ~yla~ille, imi~1~7 )1e, pyrazole, and triazole rings. Optionally, said rings may be ~lb~ rd with subst~ nt~ such as alkyl, aryl, aLkoxy, halide, and nitro. Particularly ~rer~L.~,d is the ligand

2,2'-bispyridylamine. ~f~,Ll~,d bleach catalysts include Co, Cu, Mn, Fe,-bi~y,idyl..-eth~n~
and -bispyridylamine complexes. Highly ~lcrt~lcd catalysts include Co(2,2'-30 bispyridylamine)C12, Di(isothiocyanato)bispyridylamine~obalt (II), trisdipyridylamine-cobaltaI) perchlorate, Co(2,2-bispyridylamine)202C104, Bis-(2,2'-bispyridyl~i"e) copper(II) perchlorate, tris(di-2-pyridylamine) iron(II) perchlorate, and ~ ulcs thereof.

CA 022~4818 1998-11-17 W O 97/44433 PCT~US97/08373 Plcf~ d examples include binuclear Mn complexes with tetra-N-dentate and bi-N-dentate ligands, including N4Mn~ u-O)2MnIVN4)+and [Bipy2MnIII(u-O)2MnIVbipy23-(ClO4)3.

While the structures of the bleach-catalyzing mAngAn~se complexes of the present invention S have not been elucidated, it may be spec~ t~l that they comL,lise chelates or other hydrated coordination complexes which result from the interaction of the carboxyl and nitrogen atoms of the ligand with the m~ng~nPse cation. Likewise, the oxidation state of the m~n~npse cation during the catalytic process is not known with ce,ldillLy, and may be the (~II), (+m), (+IV) or (+V) valence state. Due to the ligands' possible six points of ~tf~rhmPnt to the mAng;~n~se 10 cation, it may be reasolldbly specl~l~ted that multi-nuclear species and/or "cage" structures may exist in the aqueous blP-~ching media. Whatever the form of the active Mn ligand species which actually exists, it functions in an ~d~ y catalytic ~ to provide improved ble~hin~ ~el~o~ es on stubborn stains such as tea, k~lçh~ coffee, wine, juice.

Cobalt b}each catalysts useful herein are known, being described for example along with their base hydrolysis rates, in M. L. Tobe, "Base ~ydrolysis of Transition-Metal Complexes", Adv.
Inorg. Bioinor,e. Mech.. (1983), 2, pages 1-94. For example, Table 1 at page 17, provides the base hydrolysis rates (~esign~tlod therein as koH) for cobalt pent~min~o catalysts complexed with oxalate (koH= 2.5 x 104 M-1 s~~ (25~C)), NCS- (koHC 5.0 x 10~ M-l s-1 (25~C)), f~L~ t~ ~OH= 5.8 x 104 M-1 s-l (25~C)), and acetate (koH= 9.6 x 104 M-l s-1 (25~C)).
The most pl~r~llcd cobalt catalyst useful herein are cobalt pent~min~ acetate salts having the formula [Co(NH3)sOAc] Ty~ wll~relll OAc represents an acetate moiety, and especially cobalt pent~min~ acetate chloride, ~Co(NH3)sOAc]C12; as well as [Co(NH3)~0Ac](OAc)2;
[Co(NH3)sOAc](PF6)2; [Co(NH3)sOAc](SO4); [Co(NH3)sOAc](BF4)2; and [Co(NH3)sOAc](NO3)2 (herein HPAC").

These cobalt catalysts are readily pi~dl~;d by known procedures, such as taught for example in the Tobe article hw~,hll~efore and the refeL~ ces cited therein, in U.S. Patent 4,810,410, to Diakun et al, issued March 7,1989, J.

As a practical matter, and not by way of lilllit~tiOtl, the aulo-lldLiC dishwashing colu~)OSiliOnS and c~ nin~ pl~esses herein can be ~ eted to provide on the order of at least one pàrt per hundred million of the active bleach catalyst species in the a~ueous washing m~rli--m, and will preferably provide from about 0.01 ppm to about 25 ppm, more preferably from about 0.05 ppm to about 10 ppm, and most preferably from about 0.1 ppm to about S ppm, of the bleach catalyst species in the wash liquor. In order to obtain such - levels in the wash liquor of an automatic dishwashing process, typical duLo,l~Lic dishwashing compositions herein will COll~ se from about 0.0005% to about 0.2%, more preferably from about 0.004% to about 0.08%, of bleach catalyst, especially .~ ose or cobalt catalysts, by weight of the cle~ning compositions.

wh~le.ll Rl is a linear, branched or substituted alkyl, alkenyl, aryl, aLkaryl, ether, glycityl ether moiety cont~ining from 8 to 18 carbon atoms, plC re.dbly 8 to 16 carbon atoms, most plert lably from 8 tol4 carbon atoms; R2 is an aLIcyl group cont~ining from 1 to 3 carbon atoms, preferably methyl; R3 and R4 can vary indepen-lently and are selected from tne group co..~;~il;..g of hydrogen (pltf~lled~, methyl and ethyl; X~ is an anion such as chloride, bromide, methyl sulfate, sulfate, sufficient to provide elc~. ;r~l neutrality. A and A' can vary inrlepenrl.qntly and are each selected from Cl-C4 aL~coxy, especially ethoxy, propoxy, butoxy and u~ALul'eS thereof; p is from 1 to 30, preferably l to 15, more preferably 1 to 8, even more preferably 1 to 4 and q is from 1 to 30, preferably 1 to 15, more preferably 1 to 8, even more preferably 1 to 4. Most ~ ;re.ably both p and q are 1.

Bis-AQA cuulp~ullds wh~.eiu the hyd~ocall,yl sub~iLue.lL Rl is Cg-C~2, especially Cg-Clo, e~ re the rate of dissolution of laundry granules, es~eri~lly under cold water conditions, as colu~aled with the higher chain length materials. Accor~lill~;ly, the Cg-~12 bis- AQA ~r,~ A.-Ix may be ~l~f~ d by some form~ tr rs. The levels of the bis-AQA
sur~ct~nt~ used to ~ , fini~hPd l~ulldl~ det~lgellL col.~osilions can range from 0.1 ~ to 5%, typically from 0.45% to 2.5%, by weight. The weight ratio of bis-AQA to p~,rc~l,olldle bleach is in the range of from 1:100 to 5:1, preferably from 1:60 to 2:1, most preferably from 1: 20 to 1:1.

The present invention employs an "erre~;~ive amount" of the bis-AQA surfactants to improve the pelro. m~l.re of clP~ning compositions which contain other optional ingredients. By an "effective amount" of the bis-AQA surf~rt~nt~ herein is meant an amount which is ~~ffirient to improve, either directionally or ~iglliiirzlllly at the 90%
confirl.on~e level, the pc.fullllallce of the cleaning composition against at least some of the W O 97/44433 PCT~US97/08373 target soils and stains. Thus, in a composition whose targets include certain food stains, the form~ tf r will use sufficient bis-AQA to at least directionally improve cleaning performance against such stains. Likewise, in a composition whose targets include clay soil, the formulator will use sufficient bis-AQA to at least directionally improve cle~ning p~Lro~ ce against such soil.

The bis-AQA surf~t~nt~ may be used in combination with other d~tcl~ive ~ulra.;L~ at levels which are effective for achieving at least a directional improvement in clP~ning p~ dnce. In the context of a fabric laundry composition, such "usage levels" can vary depending not only on the type and scv~.ily of the soils and stains, but also on the wash water Iclllp~lalulc, the volume of wash water and the type of washing ~ P.

For example, in a top-loading, vertical axis U.S.-type automatic washing m~ inP using 45 to 83 liters of water in the wash bath, a wash cycle of 10 to 14 .~ s and a wash water telllpelalul, of 10~C to 50~C, it is plcf~.lcd to include from 2 ppm to 50 ppm, preferably from 5 ppm to 25 ppm, of the bis-AQA surfactant in the wash liquor. On the basis of usage rates of from 50 ml to 150 ml per wash load, this tr~n~l~tPs into an in-~,odu~t collcellL.alion (wt.) of the bis-AQA surfactant of from 0.1% to 3.2%, preferably 0.3% to 1.5 %, for a heavy-duty licluid laundry dele~5e.l~. On the basis of usage rates of from 60 g to 95 g per wash load, for dense ("compact") granular l~ ld~ y det~"gellL~ (density above 650 g/l) this tr~n~l~tes into an in-product concellL.aLion (wt.) of the bis-AQA ~ulrd~;Lall~ of from 0.2% to 5.0%, plef~"ably from 0.5% to 2.5%. On the basis of usage rates of from 80 g to 100 g per load for spray-dried granules (i.e., "fluffy"; density below 650 g/l), this tr~n~l~t~s into an in-product cc,.-~e..l . alion (wt.) of the bis-AQA surfactant of from 0.1% to 3.5%, ~n_relably from 0.3% to 1.5%.

3~or example, in a front-lo~i~, ho,i~uuLal-axis Eulc~edll-type alltom~tir wà~hi~lg ~Af'~ ,P
using 8 to 15 liters of water in the wash bath, a wash cycle of 10 to 60 ...i....~c and a wash water l~lll~,alulc of 30~C to 95~C, it is preferred to include from 13 ppm to 900 ppm, ~ fel~bly from 16 ppm to 390 ppm, of the bis-AQA ~ulrdcLdllL in the wash liquor. On the basis of usage rates of from 4~ ml to 270 ml per wash load, this tr~n~l~tPs into an in-product collcelllldlion (wt.) of the bis-AQA sulrdcldll~ of from 0.4% to 2.64%, preferably 0.55% to 1.1%, for a heavy-duty liquid laundry dcl~l~cu~. On the basis of usage rates of from 40 g to 210 g per wash load, for dense ("compact") gr~n~ r laundry dclergc~ (density above 650 g/l) this trancl~tPc into an in-product concentration (wt.) of W O 97/44433 PCTrUS97/08373 the bis-AQA surfactant of from 0.5 % to 3.5 %, preferably from 0.7 % to 1.5 %. On the basis of usage rates of from 140 g to 400 g per load for spray-dried granules (i.e., "fluffy";
density below 650 g/l), this tr~nCI~t~s into an in-product concentration (wt.) of the bis-AQA surfactant of from 0.13% to 1.8%, preferably from 0.18% to 0.76%.
Por example, in â top-loading, vertical-axis J~p~nrse-type; ~ o~ r washing m~rhinP
using 26 to 52 liters of water in the wash bath, a wash cycle of 8 to 15 .,~ s and a wash water tempe.aLul~ of 5~C to 25~C, it is pl. f~red to include from 1.67 ppm to 66.67 ppm, preferably from 3 ppm to 6 ppm, of the bis-AQA surfactant in the wash liquor. On the 10 basis of usage rates of from 20 ml to 30 ml per wash load, this translates into an in-product cQ~ .àlion (wt.) of the bis-AQA ~,ulra~ L of from 0.25% to 10%, preferably 1.5% to 2%, for a heavy-duty liquid ld.~ / del.,rgclll. On the basis of usage rates of from 18 g to 35 g per wash load, for dense ("compact") granular laundry det_~gcnLs (density above 650 g/l) this tr~ncl~tes into an in-product col~e~ tion (wt.) of the bis-AQA surfactant of from 0.25% to 10%, preferably from 0.5% tol.0%. On the basis of usage rates of from 30 g to 40 g per load for spray~ried granules (i.e., "fluffy"; density below 650 gll), this tr~nc~trs into an in-product col.cc;-lL alion (wt.) of the bis-AQA ~,ulr~;l~ll of from 0.25% tolO%, preferably from 0.5% to 1%.

As can be seen from the rOlcgoillg, the amount of bis-AQA surfactant used in a m~rhinr-wash laundering context can var;y, depending on the habits and practices of the user, the type of washing m~rllin~, In thiS context, however, one heretofore ul~l~.,iat~d advantage of the bis-AQA ,l~l r,~ is their ability to provide at least directional improvements in ~L~ rC over a ~ye~ of soils and stains even when used at relatively low levels with respect to the ot-h-er ~ul l~ x (generally anionics or anionic/n->nionir l~ Ul~S) in the fini~hrd compositions. This is to be ~;b~ u;~h.o-l from other compositions of t_e art wh~,.e.ll various cationic surF~ct~nt~ are used with anionic surf~ct~nts at or near stoichiometric levels. ID general, in the practice of t'nis invention, the weight ratio of bis-AQA:anionic surfactant in laundry compositions is in the range from 1:70 to 1:2, plcr~,ldbly from 1:40 to 1:6, preferably from 1:30 to 1:6, most preferably 1:15 to 1:8. In laundry compositions which colll~lise both anionic and nonionic surf~ct~nt~, tne weight ratio of bis-AQ~-mi~d ~nit~nir/nonionic is in the range from 1:80 to 1:2,preferably 1:50 to 1:8.

W ~ 97/~4433 , PCT~US97/08373 Various other cleaning compositions which comprise an anionic surfactant, an optional nonionic surfactant and specialized surfactants such as betaines, sl~lt~in~s, amine oxides can also be form~ t~d using an effective amount of the bis-AQA surfAct~nt~ in the manner of this invention. Such compositions include, but are not limited to, hand dishwashing S products (ecpec-i~lly liquids or gels), hard surface cleaners, shampoos, personal clc ..-ci.-g bars, laundry bars, and the like. Since the habits and practices of the users of such compositions show minim~l variation, it is s~ti~f~rtory to include from about 0.25% to about 5%, ~l~r~.ably from about 0.45% to about 2%, by weight, of the bis-AQA
surf~ t~nt~ in such compositions. Again, as in the case of the granular and liquid laundry 10 compositions, the weight ratio of the bis-AQA surfactant to other surfactants present in such compositions is low, i.e., sub-stoichiometric in the case of anionics. Preferably, such chP~nin~ compositions comprise bis-AQA/surfactant ratios as noted immP~ tPly above for m~hinP-use laundry compositions.

15 In collLld~L with other cationic sulr~ known in the art, the bis-alkoxylated cationics herein have s~rr~ l solubility that they can be used in combination with mixed surfactant ~y~ ,.,-s which are quite low in nonionic surf~ t~nt~ and which contain, for example, alkyl sulfate surfaet~ntc. This can be an important consideration for fonm-l~tors of d~t~ L
compositions of the type which are conventionally designed for use in top loading 20 ~ o.-.~t;c washing m~hinP~, eSpeci~lly of the type used in North America, as well as under J~ sc usage conditions. Typically, such compositions will cc~ lise an anionic surfactant:nonionic ~u~r;~ l weight ratio in the range from about 25:1 to about î:25, preferably about 20:1 to about 3:1. This can be co~ ds~d with Eul~ean-type forrnulas which typically will co~ ,ise anionic:nonionic ratios in the range of about 10:1 to 1:10, 25 preferably about 5:1 to about 1:1.

The ~l~fel~cd ethoxylated c~tionie surf~rt~nt~ herein are available under the trade name ET~OQUAD from Akzo Nobel Chpn~ Company. Allt;ll~ti~rely, such materials can be ~y~lhP~ d using a variety of dirrc,~ reaction schemes (wherein "EO" ~ ,e 30 -CH2CH2O- units), as follows.

A base catalyst, pl~r~,rably sodium hydroxide can be used. The mole ratio of ~ are 2:1 to 1:1 amine to alkyl sulfate. The l~,a~;lion is ~leLI~bly con~ rt~P(l using Cg-C14 alkyl sulfate, sodium salt.

The mole ratio of amine to aL~cyl sulfate is typically from 10:1 to 1:1.5; preferably from 5:1 to 1:1.1; more preferably from 2:1 to 1:1.

Suitable cl~yllles include ~ lcascs, amylases, lipases, cell-~t~es, peroxidases, and l~ urus thereof of any suitable origin, such as vegetable, animal, bacte.iaL fungal and yeast origin. I~f~,~lcd se~ction~ are i~ ed by factors such as pH-activity and/or stability optima, thPrmost~hility, and stability to active deLe ,.lL~, builders. In this respect bacterial or fungal el~ylllcs are pl~,Çcll~,d, such as bactc-ial amylases and p~oL~ascs, and 30 fungal cellnl~çs.

~ "Detc,~ivc enzyme", as used herein, means any enzyme having a c~nin~, stain removing or other~,vise ~neficial effect in a laundry, hard surface cle~ g or ~e.sollal care dcte~ L

Prercll~d detersive enzymes are hydrolases such as plOt ases, amylases and 3~ lipases. ~cr~lcd enzymes for l~ul~ly purposes include, but are not limited to, proteases, W 097/44433 pcTrus97lo8373 cellulases, lipases and peroxidases. Highly preferred for automatic dishwa~lli~ are amy1ases and/or proteases.

Enzymes are normally incorporated into d~ clll or d~le,~ellt additive compositions at 5 levels sufficient to provide a "cL ~nin~-effective amount". The term "cle~nin~ effective ~monnt" refers to any amount capable of producing a cle~ning, stain removal, soil removal, whhenin~, deodorizing, or freshness improving effect on sub~llales such as fabrics, disl,~are. In practical terms for current colln,lf r~ial pl~alions, typical amounts are up to 5 mg by weight, more typically 0.01 mg to 3 mg, of active enzyme per gram of the 10 detc~gen~ cu~ o~ilio.,. Stated otherwise, the compositions herein will typically col"~lise from 0.001 % to 5 %, preferably 0.01 %-1 % by weight of a co~mnf ~-;ial C~ylllC

Enzyme Stabilizin~ System The enzyme-cont~inin~ CWll~)OSiliOrlS herein may optionally also coll~lise from 0.001 % to 10%, preferably from 0.01)5% to 8%, most preferably from 0.01 % to 6%, by weight of an 35 ~ Gylllc stabilizing system. The enzyme stabilizing system can be any stabilizing system WO 97/444~3 PCT~US97/08373 which is compatible with ehe detersive enzyme. Such a system may be inherently provided by other formulation actives, or be added separately, e.g., by the form~ tQr or by a -m~n-lf~t lrer of delcl~scn~-ready enzymes. Such seabilizing ~ Lellls can, for example, r comprise calcium ion, boric acid, propylene glycol, shore chain carboxylic acids, boronic acids, and mixtures ehereof, and are designed to address dirre~nL stabilization problems ~lepe~ inE on the type and physical form of the dclef~ l composition.

One stabilizing aL~loacll is the use of water-soluble sources of c~ m and/or m~ s;n.-~
ions in the ~mi~hP(~ c~ o~ilions which provide such ions to the enzymes. Calcium ions are generally more errc~ e ehan m~ Ps~ ions and are ~lcfelled herein if only one type of cation is being used. Typical dct~ ll compositions, especially liquids, will COmpliSe from about 1 to about 30, preferably from about 2 eo about 20, more preferably from about 8 to about 12 millim~les of c~lci--m ion per liter of fini~hPd dclcl~clll co~ o~i~ioll, though variation is possible d~endill~ on factors including the multiplicity, eype and levels of el~y.~les inco.~ordL~ d. Preferably water-soluble calcium or m~ salts are employed, inrln~lin~ for example c~lrinm chloride, calrillm hydroxide, calcium formate, calcium malate, calcium m~lP~tP, calcium hydroxide and calcium aceeate; more generally, calcium sulfate or m~y--~s;--.n sales coll~ol~ding to the exemplified calcium salts may be used.
Further i..c:l~,ased levels of C~lrinm and/or ~ P~vl~l may of course be useful, for 20 example for ~ the grease-cutting action of certain types of surfactant.

Another stabilizing a~l~ach is by use of borate species. See Severson, U.S. 4,537,706.
Borate stabilizers, when used, may be at levels of up to 10% or more of the cornposition though more typically, levels of up to about 3% by weight of boric acid or other borate 25 cou-~oullds such as borax or orthoborate are suitable for liquid del~.~g.,.lL use. S~ss~ P~
boric acids such as phenylboronic acid, buLal~cbolol~ic acid, p-bromophenylboronic acid or the like can be used in place of boric acid and reduced levels of total boron in de~lg~
compositions may be possible though the use of such sllbstitllt~ boron dc.iva~ s.

30 Stabilizing ~y~ ls of certain cl~ Y col~l~osilions, for example ~Illo~ lir dishwashing ~ compositionc, may further co~ ;se from 0 to 10%, preferably from 0.01% to 6~ by weight, of chlorine bleach sca~ cr~, added to prevent chlorine bleach species present in many water supplies from ~ rL il~ and inactivating the enzymes, especially under ~lk~lin~o - conditions. While chlorine levels in water may be small, typically in the range from 0.5 35 ppm to 1.7~ ppm, the available chlorine in the total volume of water that comes in contact W 097/44433 PCT~US97/08373 with the enzyme, for example during dish- or fabric-washing, can be relatively large;
accordingly, enzyme stability to chlorine in-use is som~tim~s problematic. Sincepercarbonate has the ability- to react with chlorine bleach the use of additional stabilizers against chlorine, may, most generally, not be essel";~l, though improved results may be S obtainable from their use. Suitable chlorine scavenger anions are widely known and readily available, and, if used, can be salts C(J~ t;~ g ammonium cations with sulfite, bisulfite, thiosulfite, ~hioslllf~te, iodide, etc. Antioxidants such as ca~ ate, ascolbal~, etc., organic amines such as ethylenPdi~ lrt~dcetic acid (EDTA) or aL~cali metal salt thereof, monoethanolamine (MEA), and ~ ur~s thereof can likewise be used. Likewise, 10 special enzyme inhibition ~.y~tellls can be i~lcol~tulaled such that dirf~,.e,ll ~"~ynles have m~ximllm compatibility. Other conventional scavengers such as bisulfate, nitrate, ch}oride, suuices of hydrogen peroxide such as sodium perborate tetrahydrate, sodium ~ll,oldle monohydrate and sodium ~~r~;al~.olldle, as well as phosph~te~ co.~ phosphate, acetate, benzoate, citrate, ~Illlale, lactate, malate, tartrate, salicylate, etc., and llPixlu~s 15 thereof can be used if desired. In general, since the chlorine scavenger rull~lion can be ~lÇ~Illled by hlgledi~ separately listed under better recognized functions, (e.g., llydr~,gcn peroxide sources), there is no absolute re-luh~ to add a separate chlorine scavenger unless a co~ vulld ~.~lrul~ g that function to the desired extent is absent from an cl~ylllc cc..~ .ing embodiment of the invention; even then, the scavenger is added only 20 for ~illluul results. Moreover, the forml-l~tor will exercise a rh~ t's normal skill in avoiding the use of any enzyme scavenger or stabilizer which is majorly incompatible, as fonmll~tPd, with other lea -live hlg.e.iic~ .. In relation to the use of ammonium salts, such salts can be simply admixed with the deleLgelll composition but are prone to adsorb water and/or liberate ammonia during storage. Accordingly, such materials, if present, are desirably pl.jt~Ltd in a ~alliclc such as that desc~il~d in US 4,652,392, R~gin~l i et al.

Polvmeric Soil Release A~ent Known polymeric soil release agents, hereinafter ''SRA'I or "SRA's", can optionally be 30 employed in the present detcrgell~ compositions. If lltili7~ , SRA's will generally comprise from 0.01% to 10.0%, typically from 0.1% to 5%, preferably from 0.2% to 3.0% by weight, of the composition.

Pl~f~.led Sl~A's typically have hydrophilic segments to hydrophilize the surface of 3~ hydrophobic fibers such as polyester and nylon, ~nd hydrophobic se~n~nt~ to deposit upon W O 97~44433 PCT~US97~8373 hydrophobic fibers and remain adhered thereto through co~ letion of washing and rinsing cycles thereby serving as an anchor for the hydrophilic se~",cml~,. This can enable stains oc-;ùlring ~,ul>se~ucu~L to Ll~,dll~lclll with SRA to be more easily cleaned in later washing procedures.
s SRA's can include a variety of charged, e.g., anionic or even cationic (see U.S.4,956,447), as well as nr n~k~.~ed mollc.n~l units and structures may be linear, br~nrh~d or even star-shaped. They may include cdl?~h~g moieties which are e~cpeci~lly effective in controlling molecular weight or altering the physical or surface-active l,rop.,.lies.
lQ Structures and charge distributions may be tailored for application to dirr~r~ fiber or textile types and for varied dct~ cll~ or d~ nl additive products.

fe,led SR~'s include oligomeric teleph~ te esters, typically ~l~alcd by ~lucesses involving at least one l~ est~ .ir,calion/oligo~ alion, often with a metal catalyst such as 15 a l;~ ..aV) aL~coxide.

The combination of such selectef1 polymeric mAaterials (e.g., PVNO and/or PVPVI) with such selected optical bri~ ls (e.g., Tinopal UNPA-GX, Tinopal SBM-GX and/or Tinopal 30 AMS-GX) provides .~ignifir~ntly better dye transfer inhibition in aqueous wash solutions than does either of these two delergelll composition components when used alûne. Without W O 97~44433 PCT~US97/08373 being bound by theory, it is believed that such brighlellel~ work this way because they have high affinity for fabrics in the wash solution and thFler(,le deposit relatively ~uick on these fabrics. The extent to which brightPn~rs deposit on fabrics in the wash solution can be defined by a parameter called the "exhaustion coefficient". The exhaustion coefficient is in 5 general as the ratio of a) the bri~l-lellel material deposited on fabric to b) the initial bri~htr~ner concentration in the wash liquor. Bripl~ with relatively high exhAll~tion co~rrlcie~ are the most suitable for inl~ibiLillg dye l-dl~rtl in the context of the present invention.

10 Of course, it will be _~r~eiated that other, conventional optical brightPnPr types of compounds can optionally be used in the present compositions to provide co..~.,l,lional fabric "b~ .Fss" be~erll~, rather than a true dye ~ rt;l inhibiting effect. Such usage is conventional and well-known to d~ ge~ll form~ ti~ns.

15 Che~ Agents The delt;l2s~ compositions herein may also optionally contain one or more iron and/or "-A-~ Pse chPl~tin~ agents. Such çhPl~tin~ agents can be selected from the groupc~ of amino carboxylates, amino phosphonates, polyfunctionally-~.,bs~ cl aro-20 matic ch~ g agents and Illi~lur~s therein, all as hereinafter defined. Without inten-lin~
to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and ...~-g~ se ions from w~shhlg solutions by form~tion of soluble chPl~te~.

25 Amino carbo"yla~s useful as optional rhPl~ting agents include ethylel~e~ ace~ s, N-hyd~(J~.,ll~lethylPn~li~...;...~l.;~ret~tPs, nitrilotri~ret~t~s, ethyle.~ i,....;l.r L~L.d~ ionates, triethyle-~ rh -~ret~tPs~ diethyle~ n~p ~ rc~ les~ andethanoldigly~ s, allcali metal, ammonium, and ~l.sl;l~ l ammonium salts therein and ll~i~lul~s therein.
Amino pho~ph~ s are also suitable for use as chPl~ting agents in the co---i)osilions of the - invention when at least low levels of total phosphorus are pc~l.. iLIed in dcl~,g~ul compositions, and include ethyle~ cis ~methyl~nPpho~yh~lldtes) as DEQUEST.

The C1o-C14 monoeth~n-)l and ~lieth~nol amides i11l~str~t~ a typical class of such suds boosters. Use of such suds boosters with high s~ cin~ optional surf~t~nt~ such as the amine oxides, 25 betaines and slllt~in~s noted above is also advantageous. If desired, water-soluble m~-~sj.. and/or calcium salts such as M~C12, MgSO4, CaC12 CaS04, can be added atlevels of, typically, 0.1~o-2%, to provide additional suds and to el h~re grease removal ~.rO~ lce.

30 Various dt:hr~ive ingredients employed in the present colll~osiliolls optionally can be further stabilized by absoll,hlg said ingredients onto a porous hyd~hobic substrate, then coating said substrate with a hydlophobic coating. Preferably, the dctelsive ingredient is atlmixed with a ~ulrh~;~nl before being absorbed into the porous ~ul~sLl~le. In use, the detel~ive ingredient is released from the ~ul)sLlale into t~e aqueous washing liquor, where it 35 ~ s its int~n~led det~.~ive function.

_ W O 97/44433 PCT~US97~0~373 To illustrate this t~chni~e in more detail, a porous hydrophobic silica (tr~cleIn~rk SIPERNAT D10, DeGussa) is admixed with a proteolytic enzyme solution cont~ining 3%-5% of C13 15 ethoxylated alcohol (EO 7) nonionic surfactant. Typically, tne 5 enzyme/surfactant solution is 2.5 X the weight of silica. The res~llting powder is dispersed with stirring in silicone oil (various silicone oil viscosities in the range of 500-12,500 can be used). The resll1~in~ silicone oil dispersion is em~ ifi~l or otherwise added to the final dele.~ellL matrix. By this means, ingredients such as the aforementioned el.~.yllles, bl~ ~h~os, bleach activators, bleach catalysts, photoacLi~lal~,ls, dyes, fluorescers, fabric 10 conditioners and hydrolyzable surf~l~t~nt~ can be "proLecléd" for use in deL~,ge,lLs, in~ in~ liquid laundry det~rgell~ compositions.

Liquid delGrgGIlL compositions can contain water and other solvents as calliel~. Low molecular weight primary or seCorUl~ry alcohols exemplified by .~ h~-lol~ ethanol, 15 ~r~)allOI, and iSu~ pallOi are suitable. Monohydric alcohols are p,Gfel,2d for solubilizing surfactant, but polyols such as those c~ nt~inin~ from 2 to 6 carbon atoms and from 2 to 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycGlil~, and 1,2-pç~allediol) can also be used. The col~osilions may contain from 5% to 90%, typically 10% to 50%
of such ca"i~
The d~lclgenL culllL,osilions herein will preferably be formlll~ted such that, during use in aqueous cle~ning o~,aliol~, the wash water will have a pH of b~ l 6.5 and 11, ~lert;~ably b~L-.~n 7.5 and 10.5. Liquid dishwashing product formlll~tir~ns p,~rt;,dbly have a pH b.,.~,c., 6.8 and 9Ø Laundry products are typically at pH 9-11. Techni-llles for controlling pH at lcc~,.. rntl~ usage levels include the use of buffers, aLkalis, acids, etc., and are well known to those skilled in the art.

Granules ~....r~

Adding the bis-aL~oxylated cationics of this invention into a crutcher mix, followed by conventional spray drying, helps remove any residual, potentially malodorous, short-chain ~ amine co~ J~ i. In the event the formulator wishes to p,~ale an ~-lmix~hle particle CU--~ g ~he alkoxylated c~tio~i~s for use in, for example, a high density granular dct~.~,t;lll, it is pçer~ d that the particle composition not be highly ~lk~lin~. Processes for ~l~p~ing high density (above 650 g/l) gr~mllPs are described in U.S. Patent S,366,652.

, W O 97/44433 PCTrUS97/08373 Such particles may be fonmll~tP~l to have an effective pH in-use of 9, or below, to avoid the odor of i~ ul;ly amines. This can be achieved by adding a small amount of acidity source such as boric acid, citric acid, or the like, or an a~lopriate p~I buffer, to the particle. In an alternate mode, the prospective problems associated with amine malodors 5 can be masked by use of perfume ingredients, as disclosed herein.

Convention~l wisdom in the d_t~,lg~ y art suggests that b~ er.~ can ~Lilni~e the~clro~ n~e "window" of anionic sulrac~lb. Until now, however, bro~ ning the window to ellco~ ass es~ ly all conditions of water hal~"ess has been i~o~ lc to25 achieve.
