Abstract
A cosmetic composition for the hair comprises at least one water-soluble 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- and 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 (a') simple bi-functional compounds selected from bis-halohydrins, bis-azetidinium, bis-haloacyl diamine and alkyl bis-halides, (b') oligomers obtained by the reaction of (1') a compound selected from the group consisting of the compounds in (a') above or an epihalohydrin,a bis-epoxide, or a bis-unsaturated de…
