Permanent hair shaping agent useful for carrying out reductive treatment in permanent hair shaping based on hair keratin-reducing compound, comprises cationic cellulose derivative

摘要

A permanent hair shaping agent (A1) based on at least one hair keratin-reducing compound, comprises a cationic cellulose derivative formed from a cellulose ether with 1000 - 10000 repeating anhydroglucose units, and substituted by anhydroglucose unit. A permanent hair shaping agent (A1) based on at least one hair keratin-reducing compound, comprises a cationic cellulose derivative formed from a cellulose ether with 1000 - 10000 repeating anhydroglucose units, and substituted by 0.0001 - 0.1 moles per anhydroglucose unit of formula R 1R 2R 3R 4N +[A(z-)] 1 / z (I) and 0.01 - 0.9 moles per anhydroglucose unit of formula R 5R 6R 7R 8N +[A(z-)] 1 / z (II). R 1, R 2 and R 5 - R 7-CH 3 or -C 2H 5; R 3 and R 8-CH 2-CH(OH)-CH 2- or -CH 2CH 2-; R 4straight or branched 6-24C alkyl; A(z-) : anion selected from chloride, sulfate, nitrate or phosphate; and z : 1 - 3. An independent claim is included for permanently hair shaping involving treating the hair with (A1) before and/or after the hair has been set in a desired form; rinsing the hair with water if necessary after an action period for the permanent shaping; giving an oxidative post-treatment to the hair; rinsing again with water; and set in a hairstyle and finally dried.
