Abstract:
An aqueous composition comprising:(a) from 5 to 60 percent based on the weight of the aqueous composition, of one or more hydrophilic surfactant wherein the surfactant has an HLB (Hydrophilic-Lipophilic Balance) value, or a weighted average HLB (Hydrophilic-Lipophilic Balance) value, greater than 20; and (b) from 0.1 to 10 percent, based on the weight of the aqueous composition of lipophilically-modified copolymer selected from one or more of: (i) uncross-linked lipophilically-modified copolymer comprising a polyoxyethylene chain and 12 to 50 percent, based on the weight of uncross-linked lipophilically-modified copolymer, of one or more lipophilically-modified component; and (ii) cross-linked lipophilically-modified copolymer comprising a polyoxyethylene chain, at least 5 percent of one or more lipophilically-modified component, and 0.01 to 2 percent of cross-linking agent based on the weight of cross-linked lipophilically-modified copolymer; wherein the lipophilically-modified component comprises a copolymerizable vinyl ester or monoethylenically unsaturated urethane and further comprises one or more alkyl groups containing from 10 to 18 carbon atoms.
