Abstract:
A light-duty liquid or gel dishwashing detergent composition that provides beneficial skin conditioning, skin feel and rinsability aesthetics, which composition comprises:(a) from about 5% to 98% by weight of a detergent surfactant selected from the group consisting of polyhydroxy fatty acid amides; nonionic fatty alkylpolyglycosides; C.sub.8-22 alkyl sulfates; C.sub.9-15 alkyl benzene sulfonates; C.sub.8-22 alkyl ether sulfates; C.sub.8-22 olefin sulfonates; C.sub.8-22 paraffin sulfonates; C.sub.8-22 alkyl glyceryl ether sulfonates; fatty acid ester sulfonates; secondary alcohol sulfates; C.sub.12-16 alkyl ethoxy carboxylates; C.sub.11-16 secondary soaps; ampholytic detergent surfactants; zwitterionic detergent surfactants; and mixtures thereof;(b) from about 3% to 20% by weight of a skin feel and rinsability enhancing system which comprisesi) a nonionic surfactant component comprising C.sub.6 -C.sub.12 alkanols condensed with from about 5 to 15 moles of ethylene oxide; andii) a hydrotrope component comprising C.sub.1 -C.sub.3 alkyl aryl sulfonates, C.sub.6 -C.sub.12 alkanols, C.sub.1 -C.sub.6 carboxylic sulfates or sulfonates, urea, C.sub.1 -C.sub.4 hydrocarboxylates, C.sub.1 -C.sub.4 carboxylates, C.sub.2 -C.sub.4 organic diacids or mixtures of these hydrotrope materials;in a nonionic surfactant to hydrotrope weight ratio of from about 10:1 to 1:10; and(c) from about 0.001 to 5% by weight of an active protease enzyme;(d) from about 0.1 to about 4 % by weight of magnesium ions;said composition having a pH of from about 4 to 11.
