Abstract
A detergent composition comprising an alkoxylated quaternary ammonium (AQA) cationic surfactant, a non-AQA surfactant and a photobleach.
Description
DETERGEN~ COMPOSITON
Techni~l Field The present invention relates to a detergent cG.~os;tion comprising photobleach, a non-AQA sulrd~;tdnt and an alkoxylated quat~l,.~y ammonium (AQA) cationic surfactant.
l~l~und to the Invention The forrnulation of laundry dct~.~c.lts and other cle~ning co"l~itions pl~sellts a considerable çhqllPn~e~ since modern cou-~it;ons are required to remove a variety of soils and stains from diverse substrates. Thus, laundry detergents, hard surfacecleaners, ch~ oos and other pe~aonal cl~ncing co..,~;l;o~c, hand dishwashing 15 dete.E,~nts and det,.E,cnt ~I~ oc;l;onc suitable for use in ~to~ t;c dishwashers all re~uire the proper s~ and co"lbindtion of ingredients in order to function effectively. In general, such det~-gent col-.poC;~;onc will contain one or more types of surf~t~r~tc which are decigned to loosen and remove different types of soils and stains.
While a review of the lite.dtuçc would seem to indi~?~ that a wide sel~tion of 20 surf~~t~ntc and ~u~ t&ll combin~;Q- s are available to the ~te~ent m~nufactllrer~ the reality is that many such ingl~Jic.l~ are spe~ ity c~-~...ic~lc which are not suitable in low unit cost items such as home-use laundry d, hl~nts. The fact ~ll~ains that most such home-use l~iu~,~ such as laundry deb_.~,enti still mainly co",~.ise one or more of the conve .L;- n~l e~hu.~ ted nonioniG and/or sl~lf: ~ or sulfo2lat~ anionic surf~ct~ntc, 25 P1eJ~ Y due to ~4n~ con~iderations and the need to forrnulate co",~;l;onc which ~une~ion r~conqbly well with a variety of soils and stains and a variety of fabrics.
The lit~ y.~ ~e~l~ that various nil~o~el)-conl~;ning C~tiQ~i~ surf~t~nts would be 30 useful in a variety of cl~nin~ co~c;l;onc Such materials, typically in the form of amino-, amido-, or .~uat~ q-mmorlium or imi~7~1inium co,,.pounds~ are often ~eci~ned for c~q1ity use. Por example, various amino and qll-t~ .,; . y q.,.~..o~lium surfactqntc have been s.~ggesled for use in shamroo co.nl~s;l;onc and are said to provide cos~..e!;c ben~fitc to hair. Other nitrogen-con~inin~ surfactants are used in 35 some laundry d~ nts to provide a fabric softening and anti-static benefit. For the most part, however, the co".~ ..;ial use of such materials has been limited by the W 0 97/43393 PCTrUS97/08441 -~ifficlllty enco~nt~Pred in the large scale manufacture of such compounds. An ~d~itior limi~tion has been the pot~n-i~l pre~ipit~tion of anionic active coll,l)onen~ of the dete.gent co...roS;tion oc~cioned by their ionic interaction with c~tionic surf~rt~r~tc The afore.-lcntioned nQnio~ic and anionic surf~t~-lts remain the major surfactant S co.,.~ f ntc in t~day's laundry co~ ;tionC
The quick and efficiP.nt removal of different types of soils and stains such as body soils, greasy/oily soils and certain food stains, can be problematic. Such soils COlllpli~ a Illi~lUl~ of triglyc~,ndes, lipids, complex poly~e~h~lidçs inorganic salts and 10 lnutein~u~ matter all of which, are to some extent, col.~ d of hydn)phobic moieties and are thus notoriously ~1ifficult to remove. Low levels of hyd~phobic soils and residual stains often remain on the surface of the fabric after w~hing.
A wide variety of ble~l~rs for exarnple peroxygen bleach, ~hlorill~ bleaches and15 photobleaches are cornn~Qnly used in d- t~.b~nt c~ l~5;~ nC in ~drlition to SUlfi~
as m~n~ienPd above. Photobleachs are conven~;Q~ ly used under cu~u~- r~ 5 where laundered fabrics are ~lbj~hcl to c~n~n~ated light sources, such as direct sllnlight as in a line drying ope~tiQn. Photobleach is a relatively mild bleach particularly effective at d~olQu~tion of coloured ~ tnen~s (e.g. in particulate or beverage stains) 20 and removal of colour from the Ol,~alUC residues ~Ccoci~ with body soils. Theb'e3rhiltg power of the photobleach is derived from e~posure to ultra violet s~nli~ht It is bd~;e.l~d that s ~light converts the photoble~-h into an active bl~~h;~g species which then O.i~ic~c coloured stains present on the fabric. One problem lc~ t~d with the use of any 25 bleach, including the phot~bleach is the inability to completely remove residual soil and stain from the surface of the fabric. Succ~scive washing and ~ ~ing coupled withlimited soil removal in the wash c~ n~tf s in a build up of residual soil and stain which further entraps particulate dirt leading to fabric yellowing. Eventually the fabric talces on a dingy ~ r~ which is perceived as ur ~ lc and discar~ed by the 30 con~-~.-. r.
It has been discovered that certain alko~ylated quaternary ~mmoni~m (AQA) c~...~u---lc can be used in various d~t~ nt co...l~c;tionc to boost det~.~,enc~
~.r~"..an~ on a variety of soil and stain types, particularly the hydr~phobic soil types, 35 co,,-~only e-~c~ur~t~ . Un~ct~11y, it ha now been discovered that co~ oc;t;~nc CA 02254946 1998-ll-17 W O 9~/43393 PCT~US97/08441 -Cont~q-ining AQA surf;~qntc and photobleach deliver superior cle-q-ning and ~~ PnPcc pclrol..-ance versus products contqining either t~nQlQgy alone.
The AQA sur~q-r'q~ts of the present invention provide subst-q-ntiql benefits to the 5 formulator, over cqtionic surf~ q-ntc previously known. For eYq-mrle, the AQA
surf~rtqntc used herein provide marked improvement in cle-q-nin~ of "everyday"
greasy/oily hydrophobic soils regularly encountered Moreover, the AQA surf~t~ ltc are cG~ lible with anionic surf~~tqntc cQrnmo~ly used in d~te.gel l co...~ ;Qns such as alkyl sulfate and alkyl ~ e sulfonate; inco.-.patibility with anionic co-~l~n~Pnl~ of 10 the dete~gent co--lpo,;~ n has commonly been the linlitinE~ factor in the use of cqtionic r.- ~I;.n~c previously known. Low levels (as low as 3 ppm in the l~ ,, ;ne liquor) of AQA surf~t-q-ntc gives rise to the benefitc described herein. AQA s~ ntC can be forrn~1qtPd over a broad pH range from S to 12. The AQA surf~rtqntc can be p.~ das 30% (wt.) solutionc which are pumpq~ le, and lhe;~_rule easy to handle in a 15 ~--qrur~ t~ing plant. AQA surf~rtqntc with degrees of etho~ylation above S are som~tim~c p~esent in a liquid form and can ll..,..,fo~ be provided as 100% neat materials. In ~ iti~ n to their ben r~ qn~ling ~.~pe.lies, the availability of AQA
lr~ nlc as highly concPn~ t~,d solutions provides a ,,~bs~.t;~l economic advantage in llanspollation costs. The AQA S.,lll i are also co-~t;ble with various ~ ru"le 20 ingre~icontc~ unlike some ati~ ric S~lr~ known in the art.
It is beli.,~/~ that the greasy/oily soils are effectively soluhi~ d by AQA, thereby aUowing access of the photobleach to the colour bodies in the soil (e.g. entlapp~d pigmPnts) rec~lting in improved soil decolouration. The present invention thus provides 25 a d~ ,u~t c~ t;on which not only delivers superior cl~ning of both hydlophol)ic greasy/oily soils and h~dr~philic coloured soils by way of a d~te.gent co-.~s:t;~
comp~ g a AQA s.,lrd~ nt and a photobleach.

BACKGROUND ART
U.S. Patent 5,441,541, issued August 15, 1995, to A. Mehreteab and F. J. Loprest, relates to anionic/cationic ,-llr~ nt Ini~lu~s. U.K. 2,040,990, issued 3 Sept., 1980, 5 to A. P. Murphy, R.J.M. Smith and M. P. Brooks, relates to ethoxylated rqtionics in laundry detL.~ents.
Summ-q-~y of the Invention 10 The present invention provides a co...~ci~;Qn comprising or p~d by c~ h..n;np a photobleach, non-AQA surfactant and an effective qmount of an alkoxylated q,J~ yqmmnni--m (AQA) cqti~nic surfactant of the forrnula:

D~tqil~ De~~ tion of the Invention ph~toblea~h 25 The compositions of the present in~c~.lion cornrri~e a ~hotob'~~h as an css.~r~ti~l feature thereof. Photobl~ches suitable for use herein include sulfonated zinc and/or qlll..,.r.;~ phthq~ ~ines. SeeU.S. Patent4,033,718, issuedJuly5, 19~7to osnhe et al. The phthql~cyanine photoble~hPs are available for example under thetradPnqmP TINOLUX or as zinc phthqlocyanine sulfonate.
In general the phthqlQcyanines can be prepared in the ~~ ner described by Linstead and c~ . Jlh~ as r~ .~ in "Journal of the Chemi~ql Society" (p1719, 1936). As is well hlown, unc~ s~ metal phthql~cyanines are soluble in water to an unus--qlly low CA 02254946 l998-ll-l7 W O 97/43393 PCTrUS97/08441 ' s degree and are the~fole used as pigments. However water solubility can be improved by the introduction of hydrophilic groups such as sulfo, carboxy, or other ~J>~;Iue~
groups into the phthql~cyanine structure by the use of hot oleum. Sulfonated phth~locyanines are useful dyes berq~e they have an affinity for cellulose in the form 5 of either cotton or paper pulp.
As noted he.~;nabo~e, phUhqlocyanines can be readily sulfonated by heating with oleum. Thus zinc and qlumini~m phthqk~ ines which are mo~os~llfonated~
disulfonat~d, trisulfonated and tetrasulfonated can be pl~paç~. The trisulfonated and 10 tetrasulfonated species are piefe~r~d for use as photobklr.h~s The zinc tetrasulfonated and zinc trisulfonated ~hthqlocyanines are most ~ fc~

W O 97/43393 PCT~US97/08441 C12AQAsurfartqntc may be preferred by some formulators. The levels of the AQA
surf~ q-ntc used to p-e~e finish~i laundry delergent COn~pOSitiOnS can range from 0.1% to 5 %, typically from 0.45 % to 2.5 %, by weight.
5 The present invention employs an ~effective ~mount" of the AQA surf~~tq-ntc toimprove the pe.ru~ anc~ of cl~qning co.~l~sitionc which contain other adjunct ingredients~ By an "effective amount" of the AQAsurfqrtqnts and adjunct ingl~ients herein is meant an amount which is sufficient to improve, either dire~ionqlly orcigtlifirqntly at the 90% confidence level, the ~lÇul,..ance of the clc~ning c~ ~s;tio~
10 against at least some of the target soils and stains. Thus, in a cG...I~s;l;Qn whose targets include certain food stains, the formulator will use sufficient AQA to at least dire~tionqlly improve rl~qning pe.Ço.".ance ag.,inst such stains. Likewise, in ac~ ~C;~;on whose targets include clay soil, the formulator will use sufficientAQAto at least d~l;onqlly impmve clo~ pc~oi.nanc~ ag inst such soil. Importantly, in alS fully-for~n-~lqt~d laundl.~ d~te~ nt the AQAs~l~C'~ can be used at levels which provide at least a directionql improve.,.ent in cl~nil~g ~.Çol-..ance over a wide variety of soils and stains, as will be seen from the data ~ ~nted hereinafter.
As noted, the AQA slll r~ are used herein in d~te~enl co~ ;nnc in 20 cG,.~bir.ation with other detersive su.r~ at levels which are effective for achic~h~g at least a d..C~;on~l improve~l.ent in cleqning pe~l-.-ance. In the conte~t of a fabric laundry c4-..~s;L;nn~ such ~usage levels~ can vary d~ n~ not only on the type and severity of the soils and stains, but also on the wash water t~ .~pe~OI~ ,, the volume of wash water and the type of washing ~..lcl~ine For e~ample, in a top-loading, vertical axis U.S.-type ~u~ 5~;c washing l"~Ghi~ using 45 to 83 liters of water in the wash bath, a wash cycle of 10 to 14 minutes and a wash water t~ t~ of 10~C to 50~C, it is p~fe..~d to include from 2 ppm to 50 ppm, ~l~f~.dbly from S ppm to 2S ppm, of the AQA su~r~:t~nt in the wash liquor. On the basis of usage rata of from 50 ml to 150 ml per wash load, this l.~fi~ r ~ into an in-~l~luel co~ a~n (wt.) of the AQA surfactant of from 0.1% to 3.2%, p~fe.~ly 0.3% to 1.5%, for a heavy-duty liquid laundry det~.~ent. On the basis of usage rates of from 60 g to 95 g per wash load, for dense ("compact") gran~ r laundry ~oe.~cnts (density above 650 g/l) this tr~CI~t~s into an in-product co~c~nn~llion (wt.) of the AQA
su~ra~;~nt of from 0.2% to 5.0%, preferably from 0.5% to 2.S%. On the basis of usage rates of from 80 g to 100 g per load for spray-dried granules (i.e., ~fluffyn;
W 0 97143393 PCTrUS97/0844 density below 650 g/l), this tnqnC~ ps into an in-product concentration (wt.) of the AQA surfactant of from 0.1~o to 3.5%, preferably from 0.3% to 1.596.

The enzyme stabilizing system can be any stabilizing system which is co..~t;~le with the detersive enzyme. Such a system may be inherently provided by other formulqtion actives, or be added s~ r.Jy, e.g., by the 35 fo~mulq~or or by a manufacturer of de~,~,~,nt-ready enzymes. Such stabilizing systems can, for e~ample, comprise c~lri-lm ion, boric acid, propylene glycol, short chain CA 02254946 l998-ll-l7 W O 97/43393 PCTrUS97/08441 ~
carboxylic acids, boronic acids, and mixtures thereof, and are decign~ to address different stabili7~tion problems ~e~n-ling on the type and physical form of the d~t~ t c~ tiQn.
S One stabilizing approach is the use of water-soluble sources of r~lci~rn and/or . sgn~ ions in the finiched e4~ !5il;Qr~C which provide such ions to the enzymes.
ium ions are genPr~lly more effective than magnçsiunl ions and are p~f~ l~d herein if only one type of cation is being used. Typical dete.~eYll CG ~poC;~ n~esF~~ y liquids, will cQmpri~e from about 1 to about 30, p.~ f~ ~, bly from about 2 to 10 about 20, more p~f~bly from about 8 to about 12 mi11imcl~s of c~ nn ion per liter Of finich~d detefgent CG~ s;tion~ though variation is possible de~ ;n~ on factors in~lu~lin~ the ml~ y, type and levels of enzymes inc~ ated. P~f~, bly water-soluble ~lrjllrn or ...~.~c-:lJm salts are employed, includin~ for example c~
~ hlorir~P, c~lri-~n hydroxide, c~lrium fG..,-ate, calcium malate, r~ ll~ maleate, lS c~lri..m hyd~Aide and c~lcium ~ ; more generally, cqlcillm sulfate or magnesium salts coll~q~ Ain~ to the e~en plified c~lri~l~ salts may be used. Further inc~dlevels of C~4 i~m and/or M~g~c~;~.... may of course be useful, for e~ample for p.u-~.n~ g the g.~ cutting action of certain types of surfactant.
20 Another st~'~ili7~ app~oach is by use of borate spa~iPs. See 5ev~.~on, U.S.
4,537,706. Borate s~ 7prs~ when used, may be at levels of up to 10% or more ofthe con.~ n though more typically, levels of up to about 3% by weight of boric acid or other borate C~ Q~ such as bora~ or or~llûbo~ P are suitable for liquid det~ use. SUbstihltcd boric acids such as phenylboronic acid, but~ o.~ic acid, 25 p-b.~---o~hPnylbo.~,. ic acid or the lilce can be used in place of boric acid and reduced levds of total boron in det~r~,enl co~?os;~;nllc may be possible though the use of such substituted boron derivatives.
st~' ili7ir~g systems of certain cle~ni~g c~ )os;l;ons, for exarnple a'~"'~t;e 30 dish. ~shin g cQI~l~s;~ c may further comprise from 0 to 10%, p~fe.~bly from 0.01% to 6% by weight, of chlorine bleach scavenge~, added to prevent ch1~rin bleach species present in many water s~pplies from ~ cL ;ng and inactivating theerL~..~s, e~ ly unda ~ e c~n~ Qnc~ While chlorine levels in water may be small, typically in the range from 0.5 ppm to 1.75 ppm, the available chl~-nne in the 35 total volume of water that comes in contact with the enzyme, for e~mpl~ during dish-or fabric-~.~hing, can be relatively large; accordingly, enzyme stability to clllorine in-CX 02254946 l998-ll-l7 W O 97/43393 PCTrUS97/08441 use is solnP~tim~ps problematic. Since pe.~onate has the ability to react with chlorine bleach the use of ~Ai~ionq1 stabilizers against chlorine, may, most generally, not be ess~ l, 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 S co~ in;l~ qmm~nill~ cations with sulfite, bic~lfit~P, thiosnlfite~ ~hi~s.llfq~tP, iodide, etc.

Likewise, special enzyme inhibition systems can be inc~l~lat~d such that different enzymes have I~G~

Other conventinnql scaveng~ such as bisulf-q-tP, nitrate, rhl~ e, sources of hydrogen peroxide such as sodium pe~lJOldte tetrahydrate, sodium ~ l~ldle ,.onohydrate and sodium per~bondtl" as well as phos~h~, conden~d p h~,~, ~Pt:~te, benzoate, citrate, f~.,.,at~, lactate, malate, tartrate, salicylate, etc., and ll~lules thereof can be used if desired. In e~nPr~q~l, since the ch1~rin~ s~a-cn~

functi~nc, (e.g., h~d~n peroxide sources), there is no ~solute ~uhe.,.ent to add a ~ te chl~in~ scavenger unless a co,-~l o~ d ~.l~l",ing that function to the desired e~ctent is absent from an e..L~..,e co~ e en~ mPn~ of the invention; even then, the scavenger is added only for op~ ----- results.

Techni~l Field The present invention relates to a detergent cG.~os;tion comprising photobleach, a non-AQA sulrd~;tdnt and an alkoxylated quat~l,.~y ammonium (AQA) cationic surfactant.
l~l~und to the Invention The forrnulation of laundry dct~.~c.lts and other cle~ning co"l~itions pl~sellts a considerable çhqllPn~e~ since modern cou-~it;ons are required to remove a variety of soils and stains from diverse substrates. Thus, laundry detergents, hard surfacecleaners, ch~ oos and other pe~aonal cl~ncing co..,~;l;o~c, hand dishwashing 15 dete.E,~nts and det,.E,cnt ~I~ oc;l;onc suitable for use in ~to~ t;c dishwashers all re~uire the proper s~ and co"lbindtion of ingredients in order to function effectively. In general, such det~-gent col-.poC;~;onc will contain one or more types of surf~t~r~tc which are decigned to loosen and remove different types of soils and stains.
While a review of the lite.dtuçc would seem to indi~?~ that a wide sel~tion of 20 surf~~t~ntc and ~u~ t&ll combin~;Q- s are available to the ~te~ent m~nufactllrer~ the reality is that many such ingl~Jic.l~ are spe~ ity c~-~...ic~lc which are not suitable in low unit cost items such as home-use laundry d, hl~nts. The fact ~ll~ains that most such home-use l~iu~,~ such as laundry deb_.~,enti still mainly co",~.ise one or more of the conve .L;- n~l e~hu.~ ted nonioniG and/or sl~lf: ~ or sulfo2lat~ anionic surf~ct~ntc, 25 P1eJ~ Y due to ~4n~ con~iderations and the need to forrnulate co",~;l;onc which ~une~ion r~conqbly well with a variety of soils and stains and a variety of fabrics.
The lit~ y.~ ~e~l~ that various nil~o~el)-conl~;ning C~tiQ~i~ surf~t~nts would be 30 useful in a variety of cl~nin~ co~c;l;onc Such materials, typically in the form of amino-, amido-, or .~uat~ q-mmorlium or imi~7~1inium co,,.pounds~ are often ~eci~ned for c~q1ity use. Por example, various amino and qll-t~ .,; . y q.,.~..o~lium surfactqntc have been s.~ggesled for use in shamroo co.nl~s;l;onc and are said to provide cos~..e!;c ben~fitc to hair. Other nitrogen-con~inin~ surfactants are used in 35 some laundry d~ nts to provide a fabric softening and anti-static benefit. For the most part, however, the co".~ ..;ial use of such materials has been limited by the W 0 97/43393 PCTrUS97/08441 -~ifficlllty enco~nt~Pred in the large scale manufacture of such compounds. An ~d~itior limi~tion has been the pot~n-i~l pre~ipit~tion of anionic active coll,l)onen~ of the dete.gent co...roS;tion oc~cioned by their ionic interaction with c~tionic surf~rt~r~tc The afore.-lcntioned nQnio~ic and anionic surf~t~-lts remain the major surfactant S co.,.~ f ntc in t~day's laundry co~ ;tionC
The quick and efficiP.nt removal of different types of soils and stains such as body soils, greasy/oily soils and certain food stains, can be problematic. Such soils COlllpli~ a Illi~lUl~ of triglyc~,ndes, lipids, complex poly~e~h~lidçs inorganic salts and 10 lnutein~u~ matter all of which, are to some extent, col.~ d of hydn)phobic moieties and are thus notoriously ~1ifficult to remove. Low levels of hyd~phobic soils and residual stains often remain on the surface of the fabric after w~hing.
A wide variety of ble~l~rs for exarnple peroxygen bleach, ~hlorill~ bleaches and15 photobleaches are cornn~Qnly used in d- t~.b~nt c~ l~5;~ nC in ~drlition to SUlfi~
as m~n~ienPd above. Photobleachs are conven~;Q~ ly used under cu~u~- r~ 5 where laundered fabrics are ~lbj~hcl to c~n~n~ated light sources, such as direct sllnlight as in a line drying ope~tiQn. Photobleach is a relatively mild bleach particularly effective at d~olQu~tion of coloured ~ tnen~s (e.g. in particulate or beverage stains) 20 and removal of colour from the Ol,~alUC residues ~Ccoci~ with body soils. Theb'e3rhiltg power of the photobleach is derived from e~posure to ultra violet s~nli~ht It is bd~;e.l~d that s ~light converts the photoble~-h into an active bl~~h;~g species which then O.i~ic~c coloured stains present on the fabric. One problem lc~ t~d with the use of any 25 bleach, including the phot~bleach is the inability to completely remove residual soil and stain from the surface of the fabric. Succ~scive washing and ~ ~ing coupled withlimited soil removal in the wash c~ n~tf s in a build up of residual soil and stain which further entraps particulate dirt leading to fabric yellowing. Eventually the fabric talces on a dingy ~ r~ which is perceived as ur ~ lc and discar~ed by the 30 con~-~.-. r.
It has been discovered that certain alko~ylated quaternary ~mmoni~m (AQA) c~...~u---lc can be used in various d~t~ nt co...l~c;tionc to boost det~.~,enc~
~.r~"..an~ on a variety of soil and stain types, particularly the hydr~phobic soil types, 35 co,,-~only e-~c~ur~t~ . Un~ct~11y, it ha now been discovered that co~ oc;t;~nc CA 02254946 1998-ll-17 W O 9~/43393 PCT~US97/08441 -Cont~q-ining AQA surf;~qntc and photobleach deliver superior cle-q-ning and ~~ PnPcc pclrol..-ance versus products contqining either t~nQlQgy alone.
The AQA sur~q-r'q~ts of the present invention provide subst-q-ntiql benefits to the 5 formulator, over cqtionic surf~ q-ntc previously known. For eYq-mrle, the AQA
surf~rtqntc used herein provide marked improvement in cle-q-nin~ of "everyday"
greasy/oily hydrophobic soils regularly encountered Moreover, the AQA surf~t~ ltc are cG~ lible with anionic surf~~tqntc cQrnmo~ly used in d~te.gel l co...~ ;Qns such as alkyl sulfate and alkyl ~ e sulfonate; inco.-.patibility with anionic co-~l~n~Pnl~ of 10 the dete~gent co--lpo,;~ n has commonly been the linlitinE~ factor in the use of cqtionic r.- ~I;.n~c previously known. Low levels (as low as 3 ppm in the l~ ,, ;ne liquor) of AQA surf~t-q-ntc gives rise to the benefitc described herein. AQA s~ ntC can be forrn~1qtPd over a broad pH range from S to 12. The AQA surf~rtqntc can be p.~ das 30% (wt.) solutionc which are pumpq~ le, and lhe;~_rule easy to handle in a 15 ~--qrur~ t~ing plant. AQA surf~rtqntc with degrees of etho~ylation above S are som~tim~c p~esent in a liquid form and can ll..,..,fo~ be provided as 100% neat materials. In ~ iti~ n to their ben r~ qn~ling ~.~pe.lies, the availability of AQA
lr~ nlc as highly concPn~ t~,d solutions provides a ,,~bs~.t;~l economic advantage in llanspollation costs. The AQA S.,lll i are also co-~t;ble with various ~ ru"le 20 ingre~icontc~ unlike some ati~ ric S~lr~ known in the art.
It is beli.,~/~ that the greasy/oily soils are effectively soluhi~ d by AQA, thereby aUowing access of the photobleach to the colour bodies in the soil (e.g. entlapp~d pigmPnts) rec~lting in improved soil decolouration. The present invention thus provides 25 a d~ ,u~t c~ t;on which not only delivers superior cl~ning of both hydlophol)ic greasy/oily soils and h~dr~philic coloured soils by way of a d~te.gent co-.~s:t;~
comp~ g a AQA s.,lrd~ nt and a photobleach.

Photobl~ches suitable for use herein include sulfonated zinc and/or qlll..,.r.;~ phthq~ ~ines. SeeU.S. Patent4,033,718, issuedJuly5, 19~7to osnhe et al. The phthql~cyanine photoble~hPs are available for example under thetradPnqmP TINOLUX or as zinc phthqlocyanine sulfonate.
In general the phthqlQcyanines can be prepared in the ~~ ner described by Linstead and c~ . Jlh~ as r~ .~ in "Journal of the Chemi~ql Society" (p1719, 1936). As is well hlown, unc~ s~ metal phthql~cyanines are soluble in water to an unus--qlly low CA 02254946 l998-ll-l7 W O 97/43393 PCTrUS97/08441 ' s degree and are the~fole used as pigments. However water solubility can be improved by the introduction of hydrophilic groups such as sulfo, carboxy, or other ~J>~;Iue~
groups into the phthql~cyanine structure by the use of hot oleum. Sulfonated phth~locyanines are useful dyes berq~e they have an affinity for cellulose in the form 5 of either cotton or paper pulp.
As noted he.~;nabo~e, phUhqlocyanines can be readily sulfonated by heating with oleum. Thus zinc and qlumini~m phthqk~ ines which are mo~os~llfonated~
disulfonat~d, trisulfonated and tetrasulfonated can be pl~paç~. The trisulfonated and 10 tetrasulfonated species are piefe~r~d for use as photobklr.h~s The zinc tetrasulfonated and zinc trisulfonated ~hthqlocyanines are most ~ fc~

In the conte~t of a fabric laundry c4-..~s;L;nn~ such ~usage levels~ can vary d~ n~ not only on the type and severity of the soils and stains, but also on the wash water t~ .~pe~OI~ ,, the volume of wash water and the type of washing ~..lcl~ine For e~ample, in a top-loading, vertical axis U.S.-type ~u~ 5~;c washing l"~Ghi~ using 45 to 83 liters of water in the wash bath, a wash cycle of 10 to 14 minutes and a wash water t~ t~ of 10~C to 50~C, it is p~fe..~d to include from 2 ppm to 50 ppm, ~l~f~.dbly from S ppm to 2S ppm, of the AQA su~r~:t~nt in the wash liquor. On the basis of usage rata of from 50 ml to 150 ml per wash load, this l.~fi~ r ~ into an in-~l~luel co~ a~n (wt.) of the AQA surfactant of from 0.1% to 3.2%, p~fe.~ly 0.3% to 1.5%, for a heavy-duty liquid laundry det~.~ent.

On the basis of usage rates of from 140 g to 400 g per load for spray-15 dried granules (i.e., ~fluffy~; density below 650 gll), this translates into an in-lnudu~;t U~nrw~t~ ;orl (wt.) of the AQA surfactant of from 0.13% to 1.8%, p~fe.ably from 0. 18% to 0.76%.
For e~cample, in a top-loading, vertical-axis Jap'n~5e type au~ ic washing .. ~,hi~F
using 26 to S2 liters of water in the wash bath, a wash cycle of 8 to 15 .--;n~lteS and a wash water ~.u~, ~ of 5~C to 25~C, it is ~f.~ d to include from 1.67 ppm to 66.67 ppm, preferably from 3 ppm to 6 ppm, of the AQA s~ ac~nt in the wash liquor.
On the basis of usage rates of from 20 ml to 30 ml per wash load, this t~ sl~tPs into an in-~l~lu.;t c4~ "-t;on (wt.) of the AQA surfactant of from 0.25% to 10%, preferably l.S% to 2%, for a heavy~uty liquid laundry dete.~ent.

As can be seen from the fole6oillg, the amount of AQA surfactant used in a ...Q~ ;ne wash hund~ling conte~ct can vary, depe~din~ on the habits and pr~rticçs of the user, the 35 type of washing ~ h;ne, and the like. In this conte~t, however, one he~etofoIe llnappl~;dl~l advantage of the AQA surf~c!~n~c is their ability to provide at least CA 02254946 1998-ll-17 W O 97/43393 PCTrUS97/08441 -directionql improvements in performance over a spectrum of oils and stains even when used at relatively low levels with respect to the other surf~P-ntc (generally ~ ~ionics or anionic/nonionic mixtures) in the finis~led compositionc~ This is to be distinguished from other c~l-,~s;tionc of the art wherein various c~tionic surfilct-qntc are used with 5 anionic surf-q-rtqntc at or near s~ichi~!net ic levels. In general, in the practice of this invention, the weight ratio of AQA:qrio~ surfactant in laundry C4~ ~s;~;~ ns is in the range from 1:70 to 1:2, l~f~bly from 1:40 to 1:6, more p~f~ ~ably from 1:30 to 1:6, most prefe,ably from 1:15 to 1:8.

The conde ~c~t;nn p.~luc~s of ethylene oxide with a hydrophobic b. se formed by the 35 conden~q~iQn of propylene oxide with propylene glycol are also suitable for use as the q~litionql nnniQniC surfactant in the present invention. The hydrophobic portion of CA 02254946 1998-ll-17 these compounds will preferably have a molec~ r weight of from 1500 to 1800 and will exhibit water insolubility. The addition of polyoxyethylene moie~ies to this hydrophobic portion tends to increase the water solubility of the Innl~ulp as a whole, and the liquid chal.-cter of the product is retained up to the point where the 5 polyo~yethylene content is 50% of the total weight of the con~len~qtion product, which co.,~ ds to cQI~d~n~t;on with up to 40 moles of ethylene oxide.

The enzyme stabilizing system can be any stabilizing system which is co..~t;~le with the detersive enzyme. Such a system may be inherently provided by other formulqtion actives, or be added s~ r.Jy, e.g., by the 35 fo~mulq~or or by a manufacturer of de~,~,~,nt-ready enzymes.

carboxylic acids, boronic acids, and mixtures thereof, and are decign~ to address different stabili7~tion problems ~e~n-ling on the type and physical form of the d~t~ t c~ tiQn.
S One stabilizing approach is the use of water-soluble sources of r~lci~rn and/or . sgn~ ions in the finiched e4~ !5il;Qr~C which provide such ions to the enzymes.
ium ions are genPr~lly more effective than magnçsiunl ions and are p~f~ l~d herein if only one type of cation is being used. Typical dete.~eYll CG ~poC;~ n~esF~~ y liquids, will cQmpri~e from about 1 to about 30, p.~ f~ ~, bly from about 2 to 10 about 20, more p~f~bly from about 8 to about 12 mi11imcl~s of c~ nn ion per liter Of finich~d detefgent CG~ s;tion~ though variation is possible de~ ;n~ on factors in~lu~lin~ the ml~ y, type and levels of enzymes inc~ ated. P~f~, bly water-soluble ~lrjllrn or ...~.~c-:lJm salts are employed, includin~ for example c~
~ hlorir~P, c~lri-~n hydroxide, c~lrium fG..,-ate, calcium malate, r~ ll~ maleate, lS c~lri..m hyd~Aide and c~lcium ~ ; more generally, cqlcillm sulfate or magnesium salts coll~q~ Ain~ to the e~en plified c~lri~l~ salts may be used. Further inc~dlevels of C~4 i~m and/or M~g~c~;~.... may of course be useful, for e~ample for p.u-~.n~ g the g.~ cutting action of certain types of surfactant.
20 Another st~'~ili7~ app~oach is by use of borate spa~iPs. See 5ev~.~on, U.S.
4,537,706. Borate s~ 7prs~ when used, may be at levels of up to 10% or more ofthe con.~ n though more typically, levels of up to about 3% by weight of boric acid or other borate C~ Q~ such as bora~ or or~llûbo~ P are suitable for liquid det~ use.

when used alone. Without being bound by theory, it is believed that such brighteners S work this way be~q~oe they have high affinity for fabrics in the wash solution and the~fo~ deposit relatively quiclc on these fabrics. The extent to which brigl-ten -~deposit on fabrics in the wash solution can be defined by a pararneter called the "e~hqllction coefficierlt~. The e~hq~stion cQefficient is in gener~ as the ratio of a) the brig~t ne~ material ckposit~1 on fabric to b) the initial bright~n~ co.-c~t.; l;nn in the 10 wash liquor. Brighteners with relatively high eYhq-uction coeffirientc are t~he most suitable for inhibiting dye transfer in the context of the present invention.
Of course, it will be app.~iatod that other, conventirnql optical bl;ght~n~ types of c~ n~ lc can option. lly be used in the present C4...~;t;0nC to provide conv~ iQn~1 lS fabric ~bngh'n~ss~ efitc rather than a truedye hdr,sre. inhibiting effect.

when used alone. Without being bound by theory, it is believed that such brighteners S work this way be~q~oe they have high affinity for fabrics in the wash solution and the~fo~ deposit relatively quiclc on these fabrics. The extent to which brigl-ten -~deposit on fabrics in the wash solution can be defined by a pararneter called the "e~hqllction coefficierlt~. The e~hq~stion cQefficient is in gener~ as the ratio of a) the brig~t ne~ material ckposit~1 on fabric to b) the initial bright~n~ co.-c~t.; l;nn in the 10 wash liquor. Brighteners with relatively high eYhq-uction coeffirientc are t~he most suitable for inhibiting dye transfer in the context of the present invention.
Of course, it will be app.~iatod that other, conventirnql optical bl;ght~n~ types of c~ n~ lc can option. lly be used in the present C4...~;t;0nC to provide conv~ iQn~1 lS fabric ~bngh'n~ss~ efitc rather than a truedye hdr,sre. inhibiting effect.

The Clo-C14 m-noeth ~ ~ol qnd ~iethqnol arnides illustrate a typical clqss of such suds boosters. Use of such suds boo~t ,a with high sudsing optional surf~ ts such as the amine o~ide,s, ~l~ines and Cl~ ines noted above is also advantageous. If desired, water-soluble, .~g,-cc;u-,~ and/or cqk~ium salts such as MgC12, MgSO4, CaC12 CaSO4, 15 can be added at levels of, typically, 0.1%-2%, to provide ''~litionql suds and to en~qnC~ grease removal ~Çol,.,ance.
Various detersive ingf~licnts employed in the present co,npoc;l;nnc optionqlly can be fur~er stabilized by absolL,in~; s. id ingredients onto a porous hydrol,hobic s~lbsh~e, 20 then coating said substrate with a hydlu~.hob;c coating. Preferably, the detersive ing~xlient is ~ ed with a surfactant before being ab~ll,cd into the porous subsh~
In use, the detersive .n~l~iient is l~l~d from the ~lb~ te into the a~lue:uus wastling liquor, whcre it p~fu~ s its in~d~d detersive funrtion.

TypicaUy, the enzyme/su~ ~nt ssl~;Qn is 2.S X the weight of silica. The res~ ing po. dcr is dispersod with stirring in Q;licQne oil (various cilicol-e oil vi~s;l;~5 in the range of 30 50~12,500 can be used). The resulti~lg silicQne oil dis~.aion is ern~lcifi~d or otherwise added to the final dete.~cnt matrix. By this means, in~~Yxlic~t~ such as the afole--~ent;Qn~d e..LJrl,.es, bleaches, bleach activators, bleach catalysts, pho'Q~ ators, ~ dyes, fluOl~.a, fabric conditiQners and hydrolyzable sull;.c~ tc can be ~protected"

Low mole Illq~ weight primary or s~ConAq~y ~lroh~l~ el~mp1ified by m~thq~lol~ ethanol, propanol, and isopr~)panol are suitable. Monohydric alcohols are pl~ufell~d for solubilizing surfactant, but polyols such as those containing from 2 to 6 carbon atoms S and from 2 to 6 hydro~y groups (e.g., 1,3-propqn~iol, ethylene glycol, glycerine, and 1,2~ o~iol) can also be used. The co...~o~;tio~ may contain from 5% to 90%, typically 10% to 50% of such c~ulle~.
