Process for oxidative dyeing and composition for oxidative dyeing of keratinic fibres comprising a cationic amphiphilic polymer

Abstract

Abstract Keratinic fibers are dyes by applying an oxidation dye composition and developing the color with an oxidizing composition, where at least one of the compositions contains a cationic amphiphilic polymer (I) selected from quaternized cellulose or hydroxyethylcellulose derivatives having at least one alkyl, aralkyl and/or alkylaryl chain containing at least 8 carbon atoms. Process for dyeing keratinic fibers comprises applying an oxidation dye composition containing at least one developer and optionally one or more couplers and developing the color with an oxidizing composition comprising an oxidizing agent in an alkaline, neutral or acidic medium, the compositions being mixed immediately before use or applied sequentially, where at least one of the compositions contains (I). Independent claims are also included for the following: (1) an oxidation dye composition for dyeing keratinic fibers, containing at least one developer, optionally one or more couplers, and (I); (2) an oxidizing composition for oxidation dyeing of keratinic fibers, containing an oxidizing agent and (I); and (3) a multi-compartment kit in which one compartment contains an oxidation dye composition containing at least one developer and optionally one or more couplers and another compartment contains an oxidizing composition containing an oxidizing agent, where at least one of the compositions contains (I).
