Abstract:
A manually-applied detergent composition which is acceptable for dish washing applications, foams copiously in response to agitation, and exhibits time-extended foam characteristics, consisting essentially of:about 10-50% by weight of a surfactant base consisting of surfactants selected from the group consisting of anionic surfactants, nonionic surfactants and mixtures thereof; andabout 1-15% by weight of a foam stabilizer having the general structural formula: ##STR13##whereinR is selected from the group consisting of (a) an alkyl group having between 4 and 22 carbon atoms, (b) a substituted aryloxy group having between 7 and 22 carbon atoms, and (c) an alkyloxy group having between 4 and 22 carbon atoms,R' has the general structural formula: ##STR14##wherein R.sup.IV is selected from the group consisting of(a) hydrogen and (b) a methyl group, and z is an integer from 0-7,R"" is selected from the group consisting of (a) hydrogen and(b) a methyl group,R'"" is selected from the group consisting of (a) hydrogen and(b) a methyl group,n is 0 or 1,x is an integer from 1-20 and y is an integer from 1-20, such that x+y is greater than 3 but less than or equal to 20; andup to about 89% by weight of a diluent.
