- 2. A composition for treating hair, skin and nails which comprises 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,N′-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.
- 3. The method of claim 1, wherein a) is methacrylamidopropyltrimethyl ammonium chloride, b) is acrylic acid, c) is N,N′-methylenebisacryamide, and d) is methyl acrylate.
- 4. The method of claim 1, wherein said molecular weight ranges from about 50,000 to about 10,000,000.
- 5. The method of claim 1 wherein the branched or crosslinked ampholyte polymer comprises:a) about 25 to about 75 mol % acrylamidopropyltrimethyl ammonium chloride, methacrylamidopropyltrimethyl ammonium chloride, or dimethyldiallylammonium chloride; b) about 25 to about 75 mol % acrylic acid or methacrylic acid; c) about 0.0001 to 0.1 mol % N,N′-methylenebisacrylamide triallyl methyl ammonium chloride or allyl sucrose; and d) about 1 to about 35 mol % of a C1-C3 alkyl acrylate, C1-C3 alkyl methacrylate, acrylamide, N-alkyl acrylamide, methacrylamide, N-alkyl methacrylamide or diacetone acrylamide wherein the molecular weight of said polymer is at least about 10,000.
