Abstract

An aqueous detergent slurry composition comprising (A) about 5-60% of inorganic builder salts; (B) about 5-70% of detergent active matter selected from the group consisting of anionic, nonionic, cationic, amphoteric and zwitterionic surfactants; and (C) about 0.01-10% of a hydrophilic copolymer comprising a hydrophilic monomer copolymerized with an oxyethylated monomer.
