15BACKGROUND OF THE INVEN~ON
~lo~ ;c di~Lwasllu~, particularly in domPstic apE~ nc~ is an art very .en~ from fabric lmn-lPnng Domestic fabric l~md~Pring is nrrm~lly done in pu~pose-built m~chimPs having a l~ g action. These are very dinelw-L from spray a~irn d~mPstic ~-~lo~ l;r, d;~ ~l~ appl;~nGes The spray action in the 20 latter tends to cause foam. Foam can easily overflow the low sills of domPstic L~llw~ e-s and slow down the spray action, which in turn reduces the ~lo~
action. Thus in the distinct field of dom~stic n~hine di~h~L-ng, the use of c~ n foam-produc~ing laundry de~ n~ s~ nts is norm~lly r-o~stri~ted These aspects are but a brief illustration of the unique fo~ nn col~ll~ll~ in the 25 domPs~ic dishwashing field.
lllnl;l. di~l,washing with bl hing çhPmic~lc is di~e~ from fabric bl~zrl~ P In ~ lor~- I;c dishwashing, use of bl~rhing çh~mic~le involves promotion of soil removal from dishes, though soil ble~ching may also occur. ~ itinn~lly, soil antiredepos;tinn and anti-spotting effects firom 'ol ~ - ~hin~ rhem;~ ~lc would be 30 de~u ~'r Some b~~~hin~ rhPmiç~lc, (such as a hydrogen peroxide source, alone or to~et~r with tetraacetylethylP-n~ minp~ TAED) can, in certain ci~c~ c, be ~ helpful for rl~nin~ di~ ,~e, but this te~hnrlo y gives far from C~ticfi~ctQry results in a dishw~llillg co~ l for ;; ~ ability to remove tough tea stains is limited, e~e-- ~lly in hard water, and re~luil~,s rather large ~mol~ntC of bleach. Other bleach 35 a~ .lo,:i developed for laundry use can even give n~ ~ , effects, such as creating ~mcightly ~Ppocitc when put into an ~ c~nl;r di~Lwa~lfillg product, espec;~lly when they have overly low sol-lbility. Other bleach ~y~le~ls can damage items unique to di~hv~a~ g, such as silvèlw~e, ~l.. i~i.. ~ cookware or certain pl~cti~s Co~ glasses, dishware and llalw~e, especially deco,a~ pieces, as washed in dom~st~ "O~ ;C dishwashing appli~nc~C are often suscep~il,le to 5 d~m~e and can be expensive to replace. Typically, co-.c~ , dislike having to sep~le finer pieces and would prefer the convenience and cimplirity of being able to cc....h;--r all their t~b'~.a,e and coot-i~ utensils into a single, ~-~o""~l;r washing OpelaliOIl. Yet doing this as a matter of routine has not yet been ~
On accu~ 1 of the rOlegOill~ tcr~ Co~ as well as c~ needs 10 and dem~n~1c~ G---~I;C dishwashing deLel~;e~ll (ADD) compositions are undergoing co..l;~ change and i...prove..lent. More~Jvel e ~vil~ nt~l factors such as the r.ostri~ tion of phosrh~t~, the desi.~ilily of providing ever-better c~ results with less product, providing less thermal energy, and less water to assist the washing process, have all driven the need for h~lpl~ved ADD co~-.po~ nc A reco ni7ed need in ADD comrositit~n~ is to have present one or more i.~cdi~..~ which hllp~vè the removal of hot bcv~Lge stains (e.g., tea, coffee, cocoa, etc.) from c~ articles. Strong alkalis like sodium hydroxide, ble--'~s such as hyporhlorite~ builders such as pho~.l,k~s and the like can help in varying degrees but all can also be rl~m~gi~ to, or leave a film upon, glasses, di~l-~a e or 20 sil~.~.~e. Accold-l~gly, milder ADD compocitionc have been dcvcloped. These make use of a source of hydrogen peroxide, optionally with a bleach aclivaLor such as TAED, as noted. Further, w~y--,es such as cr-.----~ ;al amylolytic c.~r--.es (e.g., 1~3RMAM~ av ' ~le from Novo Nordisk S/A) can be added. The alpha-~--jlase cQmr~nPnt provides at least some benefit in the starchy soil removal 25 plup-wLies ofthe ADD. ADD's col~ lylases typically can deliver a somewhat more moderate wash pH in use and can remove starchy soiils while avoiding deli~win~ large weight equivalents of sodium hydroxide on a per-gram-of-product basis. It would the~erw'~ be highly desirable to secure h~lo~c;d bleach a~;~ivaLul~
cally ~ci nP~d to be co~ in ADD finnrtlllsttionc espe~iqlly with enzymes 30 such as ~ll~lâSeS. A need likewise exicts to secure better ~..~lase action in the pi~se lCe of bleach a.livàLo.~.
Certain ~~5tllg,ql~F,se CatalySt-CQt~ P m5tthirt~ di~hwaSllu~i~ compocitinnC are ~t5C~ ~;bed in U.S. Patent 5,246,612, issued Septt~mbt~r 21, 1993, to Van Dijk et al.
The compocitionc are said to be t hlorint bleach-free mst~hint- dishv~a >hillg compositionc CO~ J~ ;Y;~ amylase and a ~ lP ~ catalyst (in the +3 or +4 oYi~l~tion state), as defined by the structure given therein. ~l~r~..cd .~ g~-e~catalyst therein is a dimlcle~ p,~--P~P, macrocyclic ligand-co.~ g mnle~llP
said to be MnIV2(u-o)3(l~4~7-~ 4~7-triazacyclol~nl~ p)2(pF6)2. Such S catalyst m~tPri~lc which contain these more comrlie~ted ligands typically will require several synthesis steps to produce, thereby driving up the cost of the catalysts and making them less likely to be readily available for use. Thus, there cQntimles to be a need for simple, widely available catalysts that are errec~ , in ~ o...~;r, disL~ sl~ g comr5>citinnc and mPthr~s Now, r~d-~ laundry aprlir~tinnc of cobalt catalysts, simple cobalt catalysts have been dPsç~ihed for use in bleach-cc ~ --g laundry compositions towash stained fabrics as taught by U.S. Patent 4,810,410, to Diakun et al, issuedMarch 7,1989. For PY~rnrl~ Table 8 therein provides the stain removal results for a series of stains on fabrics washed with laundry co-~ o~:~;nnc with and wil}loul the 15 cobalt catalyst tCo~NH3)sCl]C12. Tea stain removal from fabrics as l~o,lc~l therein a~p~ ..~lal at best by co~ to the other stains ~--~d. Table 11 at column 16 also provides results for the oxalate c~)mrl ~, tCo(NH3)sc2o4]clo4~
and carbonate complex, tCo(NH3)sCO3]Cl. Again, b-~ Y for stain removal appear r..a,~-al.
The co-~ c infeTiority of such cobalt catalysts for laundry appl;r~ti~nc for; ~ 'e to remove tea stains, is r~-~,ed by the t~ co..~ d in the later filed Eu.op~ Patent Applir~tinn Pllb~ tion No. 408,131, ~!~blicl~ January 16, 1991 by Unilever NV. FY~ e IV therein, said to be a cc~-~p~ of the cobalt-cobalt c~ which are viewed as the invention of that :~rplir~tion versus the25 H[Co(NH3)sCl]Ck of the art" (,- r~.,;g to the earlier pUb~ tinn of the Eulul~ea~
equivalent of the above-noted Diakun et al patent), reports values for removal of tea stain as follows: Co-Co (26.3); tCo(NH3)sCl]C12 (20.6), which is lower than thatob~.~cd for a simple Mn+2 catalyst as lepo~lcd in F -- . 'e II (having a tea stain removal value of 21.4).
Sirnilar results for ~ F ~:e catalysts versus cobalt catalys~s are reported for laundry uses to remove tea stains from cotton fabrics in U.S. 5,244,594, to Favre et al., issued ~eplc~ 14, 1993. Therein, FY~mple I provides data slowing a Co-Co catalyst acco~ling to E~ 408,131 is inferior to the .~ gr~-Fse catalysts. Further, ~ FY~mrle IV also reports lower sta n removal at 20~C for a Co-Co catalyst of EP

408,131 and the [Co(NH3)sCl]C12 catalyst of the Diakun patent versus a . . .~ f ~e catalyst.
However, the callJoAyla~e ligand-co.~ cobalt catalysts useful herein are particularly useful for cons.l-l-er bleach products, given the ability to tailor the 5 physical plup~llies of these catalysts by varying the chain length and/or filn~ign~lity on the c~l,~,Aylate ligand. Thus, dep~ on the product form and inten-led use, itis possible for the present invention compositions to utilize a more Lydrophilic or hydrophobic catalyst.

DETAILED DESCRIPTION OF THE INVENTION
Bleach CG.~.~O~ OnS:

, ~ The bleach compositions of the present invention plere.ably comrriye a source of hydrogen peroxide and a particularly s~lected cobalt catalyst. The source of hydrogen peroxide is any c~ hydrogen-peroxide ~ IPA~ ~g salt, such as sodium pelbu~ale~ sodium percarbonate, and ll~lules thereo~ Also useful are S sources of available oxygen such as p~ le bleach (e.g., OXONE, m~mlf~r,t~lred by DuPont).
In the plèrelled ADD compoYitionY Pd~litirn~l iu~editllls such as water-soluble cilir,Ates (useful to provide Alk~linity and assist in controlling collui~;on)~ low-r~all~ nonionie snrf~ ntY (esperiAlly useful in ~ ;c d;:,h~sllillg to control 10 ~ul~ /filming)~ di~el~ll polymers (wh;ch modify and inhibit crystal growth ofcalcium and/or m~gn~Y;.-.-- salts), rl~Pl~ Y (which control trAnYitir~n metals),builders such as citrate (which help control cAlr;~lm and/or ...~ - and may assist l,..rr~. ;..g action), aLtcalis (to adjust pH), and detersive el~yllles (to assist with tough food rl~ning, especially of starchy and plo~ ceQ~q soils), are present. ~11rlitirn~1 15 bleach-modify-ing m~t~ri~lY such as COuv-~l;OI-~l bleach acli~alu,Y such as TAED
may be added, provided that any such bleach-modif-ying m~tPri~1q are delivered in such a manner as to be c~,---l-~l;l~le with the yul~oses of the present invention. The present delel~-nl colllpo~lions may, lllOleuvel, CQ~ ;~; one or more proc~Y-qingaids, fillers, ~ ~rl-~ Y coll~ l;on~l enyme particle-making mqt~ri~lq in 20 enzyme cores or "l~np~e;ls", as well as ~ l Y~ and the like.
In the ~rèrell~d laundry co~.pos;l;onY ~ tin~l ingredients such as builders (e.g., zeolite), anionic sllrf~et~ntq (e.g., linear allcyl b~ ne sllifon~tpc alkyl s~llfiz~t~q alkyl ethoxy suLfates), low fo~ming nonit~nic sll~f~ct~ntq soil release polymers, ~hrl~ly detersive en~yl,les, br~ h~ dye Ll~ul~er inhihitors, and/or bleach

2~ acLi~,~.lulY are present.
~ general, m~tPri~lq used for the productinn of ADD comroqitir~nq herein are plerel ~'y cl-r-L~d for co---l~ lity with s~oLI.ll~/Iilming on g~ ~a~.

from about 0.1% to about 40%, p cr~,~bly from about 0.1% to about 20% of a water-soluble silicate; and from about 0.1% to about 20%, p-~rc ably from about 0.1% to about 10% of a low-fo~min~ rlnnir- ~ sllrf~ct~nt Such fully-~...~ ed emhodimpnt~ typically further c~ e from about 0.1% to about 15% of a 10polymeric di~ ; ~-1, from about 0.01% to about 10~/ of a ~hPlsnt and from about 0.00001% to about 10% of a dclc~ enyme though further ~ itinn~l or adjunct ingredients may be present. Delc~Yf; ~I co~ o~;l;nn~ herein in granular form typically limit water cQntfnt for f~Y~mple to less than about 7% free water, for best storage stability.
15Further, l,rcrel-~d ADD co~po~;~;nnC ofthis invention are ~ ;Ally free of rhlnrin.o bleach. By '~ b~ ly free" of rhlnrine bleach is meant that the finrmll1~tnr does not delil,f;-aLely add a chlorine-cn~ bleach additive, such as a chloroiso.,~a ~u-~le~ to the prcrc -td ADD composition. However, it is recognized that be~ ~ of factors outside the control of the fc~rm~ tor, such as rhlc~rin~tit~n Of 20 the water supply, some non-zero amount of cl~ ;-.e bleach may be present in the wash liquor. The term ~ b~l; --l;~lly free" can be ~--;la ly constructed with rtrti~nce to ~1trt..c;d limit~tion of other L~di~ , such as pho ,l,h~Ie builder.
By "~r~liv~ ~.-c,u ~l" herein is meant an amount which is sl~ffir~ent, under v~Lâlcv~ cO~palali~, test cQn~1itionc are e ~.pl~_d, to enh~nr~ cle~ of a soiled25 sll~f~r~. Iikewise, the term "catalytically e~t~ refers to an amount of cobalt catalyst which is sllffi~ent under wl-altvel co~ live test cQn~litinn~ are 1, lo~_d, to f l~h~ e rl~nin~ of the soiled surface. In n~O~ I;c di~l-w~l~ , thesoiled surface may be, for f ~ ilc~ a porcclaill cup with tea stain, dishes soiled with simple ~ es or more compleY food soils, or a plastic spatula stained with tomato30 soup. The test con-l;l;ol~C will vary, depen~iin~ on the type of v~l.u~g appliance used and the habits ofthe user. Some m~chinPs have con~ rably longer wash cycles thanothers. Some users elect to use warm water without a great deal of heating inside the applial ce, others use warm or even cold water fill, followed by a warm-up through a built-in f~lectnr~l coil. Of course, the p~ru....~ce of ble~rhlos and CA 02224559 l997-l2-ll el~y~lles will be ~ff~cted by such cQn~;dPrations, and the levels used in fully-fio~~ ted d~lel~clll and t~ nin~ compositions can be a~)plo~lialcly ~dil~cted Cobalt Catalysts:

The enzyme ~l~k.l;,;..g system can be any st~bili7ing system which is co~ nlible with the delel~ve en_yme. Suchst~bili7ing ~y~lems can cc~ ;cG c~lr;~lm ion, boric acid, propylene glycol, short chain c~ubu~yLc acid, boronic acid, and r,,,~Lul~,s thereo~
The st~hili7ing system of the ADDs herein may further co.. ~ e from 0 to about 10%, prcr~ ably from about 0.01% to about 6% by weight, of rhlorimP bleachs~,av~;ngtl~ added to prevent chl~lrine bleach species present in rnany water ~pp?ics from ~tt~ ing and ina;LivaLi-.~ the cl~y...es, especiaUy under ~ inP c~nrliti~nQWhile chlorin~ levels in water may be smalL typicaUy in the range from about 0.525 ppm to about 1.75 ppm, the available rhlorinP in the total volume of water that comes in contact with the enyme during di:,Lwasllil~; is relatively large; acco-di--~ly, enzyme stability in-use can be problem~tic ~~ ~sb?- chl~ rinç SCav~llgei anions are ~-videly known and readily available, and are iUu~ aLed by salts c~ ...g ~ o~ . cations with sulfite, ~ lfite, th;Os llfit~

citrate, fo~ ale~ lactate, malate, tartrate, salicylate, etc., and ~I~Lul. s thereof can be - used if desired. In general, since the chl~rin~ scavenger filn~tion can be p~lformPd by several ofthe ingredients sepalalely listed under better recognized filnrtion~ (e.g., - 5 other CO~ OIlellLS of the invention such as sodium pellJol~le), there is no leyull~ to add a se~alàle ~hlorin~o Scav~ ,el unless a col..i~ou..d p,. ru....~ that fi~nctirm to the desired extent is absent from an e.~ylllc cc...l~;..;~.g embodiment of the invention; even then, the sca~enger is added only for opL.ll-ulll results. Moreove, the form~ tor will c,~ercisc a chemist's normal skill in avoiding the use of any10 scavenger which is majorly ~ o~ le with other ingredients, if used. In relation to the use of ~ o~ salts, such salts can be simply a~lmiy~od with the delel~;clll comrosition but are prone to adsorb water and/or liberate ~ o~ during storage.

Method for Cleaning:
The present invention also f -~CC)~ CPS a method for ~1FP~ 8 soiled tableware 10 cQmrri~i~ cQnt~rti~ said tableware with an a~ leouC ~--P~l;---CQ~ a cobalt catalyst, plerelably at a co~ lion of from about 2 ppm to about 10 ppm, as ~les~ ed herein before. Plerelled ~queo--s me(lillm have an initial pH in a washso1lltion of above about 8, more plerelably from about 9.5 to about 12, most plere~bly from about 9.5 to about 10.5.

Rinse Aid CGIIII)O~ liOnS and Methods:
The present invention also relates to compocitinnc useful in the rinse cycle of an _,~ln", ~I;c dish~l~,g process, such cQr.l~o~:l;onc being c~ y lerell~,d to as ~ri~se aidsn. While the hc,~ :-~l-effire described co...l~oc:l;ot c may also be rc~ led to be used as rinse aid compositinnc~ it is not lc-luucd for purposes of use as a rinse aid to have a source of hydrogen peroxide present in such comFocitionC (~ltho -gh a 25 source of l."LIug~l peroxide is p~crell ed, at least at low levels to at least s~lrple~n~nt the car~y-over).
The optinn~l inr~ ;on of a source of hydrogen peroxide in a rinse aid co. . ~ro ~ ' ;nn is pos. ble in view of the fact that a ci~ .; r~ .l level of residual dclelgell~
co...ros:~;n~ is carried over from the wash cycle to the rinse cycle. Thus, when an 30 ADD cr~nl~oc;linn co--l~ y a hydrogen peroxide source is used, the _ource of hydrogen peroxide for the rinse cycle is carry over from the wash cycle. Catalytic activity provided by the cobalt catalyst is thus eLrecli~,., with this carry-over from the wash cycle.

Thus, the present invention further encomp~cs~s automatic dishwashing rinse aid compositions co~ . (a) a catalytically e~ective ~mount of a cobalt catalyst as dP ~ .. ;bcd herein, and (b) ~l~tom~tic disl-w.lsh,.,g d~lel~2c~l adjunct m~teri~lc ~ rt;llc;d comFosi~innc co~ a low fo~mir~g n~lniQniC ~ r~ l These 5 comro.citinns are also preferably in liquid or solid form.
The present invention also e~rQ~ Acses mPth~ -ls for washing tableware in a domestic ~ O...hl;~ dishwashing appliance, said method cc....p.;~ eaL~ the soiled tableware during a wash cycle of an ~ Q~ ;C ~ Lwasher with an ~queous ling bath c~ ;s:~ a source of hydrogen peroxide, foltowed by treating the 10 tablL~ t, in the ~.lbse~ ont rinse cycle with an ~queous bath c~mpncing a cobatt catatyst as ~Y~ e~ herein.
Synthesis Methods for Cobalt Catalysts:
The cobatt bleach catalysts having carboxylate ligands may further be made by the following ~,ltlles.s metho~lC which are illu,tlated for the ~ elled catatysts [Co(NH3)sOAc] C12; [Co(NH3)sOAc] (OAc)2; and [Co(NH3)sOAc](PF6)2.
