摘要：
A cosmetically acceptable composition comprising from about 0.1 to about 10weight percent, based on polymer solids, of a water-soluble ampholyte polymercomprising: from at least 1 to as much as 95 weight percent of the nonionic monomeracrylamide from at least 5 to as much as 80 weight percent of the cationic monomerdimethyldiallylammonium chloride from at least 1 to as much as 75 weight percentof the anionic monomer acrylic acid, is disclosed. The application of these polymersto a keratinous substance is also disclosed. In addition, a method of treatinga keratinous substance comprising applying a cosmetically acceptable compositioncomprising from about 0.1 to about 10 weight percent, based on polymer solids,of an ampholyte polymer produced by the foil owing process: (1) preparing a monomersolution containing: from at least 1 to as much as 95 weight percent of the nonionicmonomer acrylamide from at least 5 to as much as 80 weight percent of the cationicmonomer dimethyldiallylammonium chloride from at least 1 to as much as 75 weightpercent of the anionic monomer acrylic acid (2) providing a reactor and waterto said reactor (3) optionally charging said reactor with a sequestering agent,a chain transfer agent or a combination thereof (3) purging said reactor to removeoxygen from said reactor (4) heating the contents of said reactor and (5) feedingsaid monomer solution and initiator solution into said reactor, is disclosed.
