Abstract:
A cosmetic or dermatological rinse-out composition, comprising, in a cosmetically or dermatologically acceptable aqueous medium,a) at least one zwitterionic polymer resulting from the copolymerization of at least one monomer of formula (I): â€ƒin which R1 and R2, which are identical or different, are chosen from a hydrogen atom and a methyl radical, and R3, R4 and R5, which are identical or different, are chosen from linear and branched alkyl radicals containing from 1 to 4 carbon atoms, Z is chosen from an NH group and an oxygen atom, n is an integer from 2 to 5, Aâˆ’ is an anion of an organic or inorganic acid, and at least one monomer of formula (II): R6â€”CH&boxH;CR7â€”COOHâ€ƒâ€ƒ(II) â€ƒin which R6 and R7, which are identical or different, are chosen from a hydrogen atom and a methyl radical; wherein said at least one zwitterionic polymer is soluble in water to a concentration of 1% by weight at a pH below 6 and at 20Â° C.; b) at least one non-amino, non-volatile, water-insoluble silicone having a viscosity of greater than 300 centistokes; and c) a washing base present in an amount ranging from 4 to 30% by weight relative to the total weight of the composition, wherein the washing base comprises at least one surfactant.
