Oligomeric esters and mixtures thereof useful as soil release agents in consumer laundering and fabric care compositions are disclosed. Preferred oligomers have the formulae
wherein E is
or
wherein the R substituents may be the same of different and are members selected from the group consisting of -CH2CH(CH3)-, -CH(CH3CH2-and -CHzCHr, n is an integer from 1 to 30 and x is an integer from 0 to about 20 provided and when E is
x is at least 1. Mixtures of the oligomers having one and two NaO3S(CH2CH2O)n-substituents are particularly effective and formulable soil release in detergent compositions.
