ABSTRACT:
The invention relates to a composition used for the treatment of keratin substances which contains at least one amphoteric polymer containing units A and B randomly distributed in the polymer chain, where A denotes a unit derived from a monomer containing at least one basic nitrogen atom and B denotes a unit derived from an acid monomer containing one or more carboxyl or sulphonyl groups, or alternatively A and B can denote groups derived from zwitterionic carboxybetaine monomer, A and B can also denote a cationic polymer chain containing secondary or tertiary amine groups or quaternary ammonium groups, in which chain at least one of the amine groups carries a carboxyl or sulphonyl group joined via a hydrocarbon radical, or alternatively A and B form part of a chain of a polymer with alpha, beta-dicarboxyethylene units, in which one of the carboxyl groups has been reacted with a polyamine containing one or more primary or secondary amine groups, and at least one cationic polymer of the polyamine or poly-(quaternary ammonium) type, containing amine or ammonium groups in the polymer chain or joined to the latter.
