Claim 2
Dependent Claim
95 words
A detergent or personal product composition comprising: (a) a compound selected from the group consisting of: ##STR8## wherein: R 1 is a linear or branched, saturated or unsaturated alkyl group having 1 to 50 carbons; R 2 and R 3 are hydrogen or a linear or branched, saturated or unsaturated alkyl group having 1 to 50 carbons; and R 4 is --(CHOH) n' --CH 2 OH; wherein n' is 0 to 5; and (b) a detergency effective amount of a detergent additive selected from the group consisting of a surfacant, an enzyme and mixtures thereof.
Claim 3
Dependent Claim
33 words
