Abstract
A cosmetic composition for the hair comprises at least one water-soluble crosslinked polymer selected from the group consisting of (1) crosslinked polymer obtained by crosslinking a polyamino-polyamide with a crosslinking agent, said polyamino-polyamide being prepared by the polycondensation of (a) an acidic compound selected from the group consisting of (i) organic dicarboxylic acid, (ii) ethylenically unsaturated aliphatic mono- or di- carboxylic acid, (iii) ester of said acids of (i) and (ii), and (iv) mixtures of (i), (ii) and (iii) on (b) a polyamine selected from the group consisting of bis primary and mono- or bis-secondary polyalkylene polyamines, said polyamine (b) being replaceable by a member selected from the group consisting of (1) 0-20 mole percent hexamethylene diamine, (2) 0-40 mole percent bis-primary amine and (3) 0-40 mole percent bis-secondary amine, said crosslinking agent being selected from the group consisting of epihalohydrins, diepoxides, dianhydrides and bis unsaturated derivatives, and being employed in amounts of 0.025-0.35 mole per amine group in said polyamino-polyamide and (2) the crosslinked polymer of (1) alkylated with an alkylating agent selected…
