COMPOSITIONS FOR TREATING KERATINOUS MATERIALS CONTAINING A COMBINATION OF A ZWITTERION POLYMER AND A WATER INSOLUBLE NON-VOLATILE SILICON

摘要

The invention concerns a composition for treating keratinous materials in particular hair, containing in a cosmetically and/or dermatologically acceptable aqueous medium at least: a) a zwitterion polymer derived from the copolymerisation of at least one monomer of formula (I) in which: R1 and R2, identical or different, represent a hydrogen atom or a methyl radical; R3, R4 and R5, identical or different, represent a C1-C4 linear or branched alkyl radical; Z represents a NH group or an oxygen atom; n is a whole number between 2 and 5; A<-> is an anion derived from an organic or mineral acid; and at least a monomer of formula (II) in which: R6 and R7, identical or different, represent a hydrogen atom or a methyl radical; said polymer being water soluble at 1 wt.% with pH less than 6 and at 20 DEG C; b) a non-amine, non-volatile, water insoluble silicon with viscosity higher than 3.10<5> m<2>/s (300 centistokes).
