Abstract

A stable aqueous detergent composition, comprising: (a) about 5.70% of detergent active matter selected from the group consisting of anionic, nonionic, cationic, amphoteric, and zwitterionic surfactants; (b) about 1-60% of one or more electrolytes; and (c) about 0.01-5% of at least one hydrophilic copolymer comprising hydrophilic monomer and oxyethylated monomer. In particular, the hydrophilic copolymer is of a structure represented by ##STR1## wherein the above-stated substituents are defined herein.
