Abstract:
A method for treating hair, skin or nails comprising contacting the hair, skin or nails with a composition comprising 0.1% to 10% by weight, in a cosmetically acceptable medium, of a branched or crosslinked ampholyte polymer comprising:a.) about 20 to about 95 mol % acrylamidopropyltrimethyl ammonium halide, methacrylamidopropyltrimethyl ammonium halide, methyloyloxyethyl trimethyl ammonium halide, methyloyloxyethyl trimethyl ammonium methylsulfates, acryloyloxyethyl trimethylammonium halide or dimethyl diallyl ammonium halide; b.) about 5 to about 80 mol % of acrylic acid, methacrylic acid, 2-acrylamido-2-methylpropane sulfonic acid or 2-methacrylamido-2-methylpropane sulfonic acid; c.) about 0.0001 to about 1 mol % N,Nâ€²-metyhylenebisacrylamide triallyl methyl ammonium chloride, allyl methacrylate, N-methylol acrylamide, polyethylene glycol dimethacrylate, ethylene glycol dimethacrylate, ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, 1,6-hexanediol dimethacrylate, and allyl sucrose; and d.) about 1 to about 50 mol % of C1-C3 alkyl methacrylate, C1-C3 alkyl acrylate, acrylamide, N-alkylacrylamide, methacrylamide, N-alkylmethacrylamide, and diacetone acrylamide; wherein the weight average molecular weight of said polymer, as determined by viscometry, is at least about 10,000.
