Patent ID: 8658145

Claim:
A cosmetically acceptable composition comprising from about 0.1 to about 10 weight percent, based on polymer solids, of an ampholyte polymer comprising: (a) from at least 36 to as much as 40 weight percent of the nonionic monomer acrylamide of the following formula: where R is H or CH 3 ; and R 1 and R 2 are independently H, C 1-4 alkyl, CH 2 OCH 3 , CH 2 OCH 2 CH(CH 3 ) 2 , (CH 2 CH 2 O—) x —H, where x=1-50, or phenyl, or together are C 3-6 cycloalkyl; (b) from at least 15 to as much as 29 weight percent of the cationic monomer dimethyldiallylammonium chloride of the following formula: where R 1 and R 2 are independently H or C 1-12 alkyl, and the moiety − Y is a suitable anion; (c) from at least 31 to as much as 40 weight percent of the anionic monomer acrylic acid of the following formula: where R is H or CH 3 ; and R 1 is X + , H, and X + is a suitable cation forming a salt of the carboxylic acid; and wherein the weight average molecular weight of said polymer is from about 5 thousand to about 250,000.
