ABSTRACT:
Oligomeric esters and mixtures thereof useful as soil release agents in consumer laundering and fabric care compositions are disclosed. Preferred oligomers have the formulae ##STR1## wherein E is ##STR2## wherein the R substituents may be the same or different and are members selected from the group consisting of --CH.sub.2 CH(CH.sub.3)--, --CH(CH.sub.3)CH.sub.2 --and --CH.sub.2 CH.sub.2 --, n is an integer from 1 to 30 and x is an integer from 0 to about 20 provided that when E is ##STR3## x is at least 1. Mixtures of the oligomers having one and two NaO.sub.3 S(CH.sub.2 CH.sub.2 O).sub.n --substituents are particularly effective and formulable soil release agents in detergent compositions.
