Abstract
The invention provides non-aqueous compositions comprising film forming polymers comprising repeating units derived from: (a) at least one monomer comprising at least one functionalized or unfunctionalized acryloyl moiety and at least one lactam moiety; (b) at least one monomer selected from the group consisting of functionalized and unfunctionalized C1-C7 alkyl (alk)acrylates, C1-C7 alkyl (alk)acrylamides, and combinations thereof; and (c) at least one monomer selected from the group consisting of functionalized and unfunctionalized C8-C60 alkyl (alk)acrylates, C8-C60 (alk)alkyl acrylamides, and combinations thereof. The invention further provides applications of these compositions in various industrial arts, particularly in personal care. The invention furthermore provides water-resistant non-aqueous personal care compositions. Variables a, b and c are described herein.
