The present invention relates to a cosmetic composition comprising: (a) one or more antidandruff agents, and (b) one or more amphoteric polymers comprising a repetition of: (i) one or more units derived from a monomer of (meth)acrylamide type, (ii) one or more units derived from a monomer of (meth)acrylamidoalkyltrialkylammonium type, (iii) one or more units derived from an acidic monomer of (meth)acrylic acid type. The invention also relates to a cosmetic process for treating keratin fibers using such a composition, and to a cosmetic use for facilitating the styling and/or for improving the suppleness, smoothness and/or disentangling of the hair.

Cosmetic composition comprising at least one particular amphoteric polymer and an antidandruff agent

Disclosed herein is novel detergent and conditioning composition comprising, in a cosmetically acceptable medium, at least one sulfate or sulfonate anionic surfactant, at least one carboxylic anionic surfactant other than the preceding surfactant, at least one amphoteric surfactant and at least one amino silicone, wherein the sulfate or sulfonate anionic surfactant/carboxylic anionic surfactant weight ratio ranges from 2 to 12, and the surfactants are present in the composition in a total amount ranging from 4% to 35% by weight relative to the total weight of the composition. Also disclosed herein is a method for cleansing and/or caring for keratin materials such as the hair or the skin comprising applying this composition to the keratin materials.

Detergent cosmetic compositions comprising at least one amino silicone, and use thereof

The present disclosure relates to novel detergent and conditioning compositions comprising, in a cosmetically acceptable medium, at least one sulfate or sulfonate anionic surfactant; at least one carboxylic anionic surfactant chosen from polyoxyalkylenated (C-C)alkyl ether carboxylic acids, polyoxyalkylenated (C-C)alkylaryl ether carboxylic acids and salts thereof, polyoxyalkylenated and (C-C)alkylamido ether carboxylic acids and salts thereof; at least one amphoteric and/or zwitterionic surfactant; and at least one water-insoluble carboxylic acid ester chosen from: 1) esters of a C-Ccarboxylic acid and of a C-Calcohol, with at least the acid or the alcohol being branched, and 2) esters of a C-Caromatic acid whose carboxylic functional group is directly attached to the aromatic ring and of a C-Calcohol; wherein the at least one water-insoluble carboxylic acid ester is present in an amount ranging from 0.5% to 10% by weight, relative to the total weight of the composition, and further wherein the sulfate or sulfonate anionic surfactant/carboxylic anionic surfactant weight ratio ranges from 2 to 12. The present disclosure also relates to a process for using the novel composition to cleanse and care for keratin materials, such as the hair, or the skin.
