ABSTRACT:
Dispersion concentrates are claimed which consist of:I) 10-80% by weight of a crosslinked copolymer obtained by polymerization of 1 to 50% by weight of a cyclic N-vinylcarboxamide and 49.99 to 98.99 by weight of acryloyldimethyltauric acid,II) 20-90% by weight of a phase selected from the group consisting of an emulsifier, an oil phase, and mixtures thereof, andIII) up to 30% weight water based on the total weight of the stable dispersion concentrate. The stable dispersion concentrate is useful in preparing cosmetic, pharmaceutical, and dermatological compositions.
