Problems solved by technology

This "build-up" effect is due to the continuous deposition of the conditioning agent on these fibers without the previously deposited agent being properly removed
Consequently, the deposition of the conditioner becomes thicker and thicker, resulting in a flat and weak fiber

Abstract

The invention discloses a cosmetic composition comprising at least one particular amphoteric polymer and an antidandruff agent. 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 fibres using such a composition, and to a cosmetic use for facilitating the syling and / or for improving the suppleness, smoothness and / or disentangling of the hair.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 201280030226.5 entitled "Cosmetic Composition Containing At least One Specific Amphoteric Polymer and Anti-dandruff Agent" dated June 22, 2012. technical field [0002] The present invention relates to a cosmetic composition for the treatment of keratin fibers, especially human keratin fibers such as hair, comprising one or more specific amphoteric polymers and one or more anti-dandruff agents. [0003] The invention also relates to a cosmetic method for treating keratin fibers using such a composition, and also to the cosmetic use of said composition. Background technique [0004] Numerous hair care compositions containing one or more antidandruff agents have been proposed in the prior art to prevent the formation of dandruff. [0005] Currently, anti-dandruff shampoo users often have hair that is more or less sensitive, i.e. caused by external atmospheric factors such as light and bad wea...
