(b) from about 20% to about 90% solvent having a solubility
parameter value outside about ±4 of said diacyl peroxide's
solubility parameter; and
(c) from about 0.01% to about 10% chelant, said chelant
selected from the group consisting of sodium, potassium,
lithium, ammonium and substituted ammonium salts of
ethylenediamine tetraacetic acid, ethylenediamine disuccinic
acid, nitrilotriacetic acid, tartarate monosuccinic acid,
tartarate disuccinic acid, oxydisuccinic acid, carboxy-
methyloxysuccinic acid, mellitic acid, sodium benzene
polycarboxylate salts, nitrilotris(methylene phosphonic
acid), diethylenetrinitrilopentakis(methylenephosphonic
acid), 1-hydroxyethane-1,1-diphosphonic acid, ethylene-N,N'-
bis(o-hydroxy-phenylglycine), dipliolinic acid, diethylene
triamine penta(methylene phosphonate), hexamethylene diamine
tetra(methylene phosphonate), ethylenediaminotetracetic
acid, ethylenetriamine pentacetic acid, ethylenediamine-
N,N'-disuccinic acid, iminodiacetic acid derivatives,
ethylene diphosphonic acid, organo phosphonic acid, and
mixtures thereof;
wherein said composition has a neat pH from about 7 to about 13;
and wherein said diacyl peroxide is undissolved in said liquid,
alkaline detergent composition.
The examiner relies upon the following references as
evidence of obviousness:

Appellant's claimed invention is directed to a liquid,
alkaline detergent composition, such as dishwasher detergent,
which consists essentially of a diacyl peroxide of the recited
formula, a solvent having a solubility parameter outside the
diacyl peroxide's solubility parameter and a chelant. The diacyl
peroxide is undissolved in the liquid detergent composition.
