Summary: | A cosmetically acceptable composition comprising from about 0.1 to about 10 weight percent, based on polymer solids, of a water-soluble ampholyte polymer comprising: from at least 1 to as much as 95 weight percent of the nonionic monomer acrylamide; from at least 5 to as much as 80 weight percent of the cationic monomer dimethyldiallylammonium chloride; from at least 1 to as much as 75 weight percent of the anionic monomer acrylic acid, is disclosed. The application of these polymers to a keratinous substance is also disclosed. In addition, a method of treating a keratinous substance comprising applying a cosmetically acceptable composition comprising from about 0.1 to about 10 weight percent, based on polymer solids, of an ampholyte polymer produced by the following process: (1) preparing a monomer solution containing: from at least 1 to as much as 95 weight percent of the nonionic monomer acrylamide; from at least 5 to as much as 80 weight percent of the cationic monomer dimethyldiallylammonium chloride; from at least 1 to as much as 75 weight percent of the anionic monomer acrylic acid; (2) providing a reactor and water to said reactor; (3) optionally charging said reactor with a sequestering agent, a chain transfer agent or a combination thereof; (3) purging said reactor to remove oxygen from said reactor; (4) heating the contents of said reactor; and (5) feeding said monomer solution and initiator solution into said reactor, is disclosed. |
