Detergent cosmetic composition comprising anionic and amphoteric surfactants, a highly charged cationic polymer and a water-soluble salt

摘要

The invention relates to a detergent composition containing, in a cosmetically acceptable aqueous medium, at least one anionic surfactant and at least one amphoteric surfactant chosen from (C₈-C₂₄)alkylamido(C₃-C₈)alkylbetaines, sulfobetaines, (C₈-C₂₄)alkyl-amido(C₆-C₈)alkylsulfobetaines, (C₈-C₂₄)alkyl amphomonoacetates, (C₈-C₂₄)alkyl amphodiacetates, (C₈-C₂₄)alkyl amphomonopropionates, (C₈-C₂₄)alkyl amphodipropionates and phosphobetaines, in an anionic surfactant(s)/amphoteric surfactant(s) weight ratio of less than or equal to 1; at least one cationic polymer with a cationic charge density of greater than 5 meq/g, and at least 1% by weight, relative to the total weight of the composition, of at least one mineral or organic water-soluble salt, the anion of this salt comprising from 1 to 7 carbon atoms, the total amount of surfactants in the composition being less than or equal to 18% by weight relative to the total weight of the composition. This composition is especially used for washing and conditioning keratin materials, for example the hair.
