The present invention is related to an aqueous cleansing composition for keratin fibres, especially human hair, comprising at least one amino acid surfactant, and a cationic polymer. Accordingly, the object of the present invention is an aqueous cleansing composition comprising at least one amino acid surfactant of structure (I) wherein R 1 is a saturated or unsaturated, straight or branched alkyl chain with 7 to 17 C atoms, R 2 is H or a methyl, R 3 is H, COO − M + , CH 2 COO − M or COOH, n is 0 to 2, X is COO − or SO 3 − and M is independent from each other H, sodium or potassium, and a cationic polymer consisting of a copolymer of vinylpyrrolidone and vinylimidazole and a homopolymer of dimethyl dially ammonium chloride. |
