Composition used for cleaning body/conditioning hair, comprises hydrophobically modified cellulose having hydrophobic group, and liquid fatty alcohol, where modified cellulose comprises main chain constituted by nonionic cellulose ether
Cosmetic composition comprises hydrophobically modified celluloses having hydrophobic groups (greater than 0.6 wt.%), and liquid fatty alcohols, where: the hydrophobically modified celluloses comprise a main chain constituted by a nonionic cellulose ether on which hydrophobic groups are provided； and the hydrophobic groups comprise (1) 3-alkoxy-2-hydroxy group (3-6C alkyl) in which the fragment alkoxy is linear or branched and comprises 5-30C, preferably 3-alkoxy-2-hydroxypropyl group and/or (2) 9-30C (preferably 12-18C) alkyl and 6-30C aryl, arylalkyl and alkylaryl groups. Cosmetic composition comprises hydrophobically modified celluloses having hydrophobic groups (greater than 0.6 wt.%), and liquid fatty alcohols, where: the hydrophobically modified celluloses comprise a main chain constituted by a nonionic cellulose ether on which hydrophobic groups are provided； the hydrophobic groups comprise (1) 3-alkoxy-2-hydroxy group (3-6C alkyl) in which the fragment alkoxy is linear or branched and comprises 5-30C, preferably 3-alkoxy-2-hydroxypropyle group and/or (2) 9-30C (preferably 12-18C) alkyl and 6-30C aryl, arylalkyl and alkylaryl groups； and the hydrophobically modified celluloses do not comprise 3-8C non alkoxylated alkyl group. An independent claim is included for conditioning hair or washing/cleaning body, comprising applying the composition on the keratinous material and then rinsing after an exposure time with or without heat.La présente invention concerne une composition cosmétique de nettoyage du corps ou de conditionnement des cheveux comprenant une ou plusieurs celluloses hydrophobiquement modifiées ayant une teneur en groupe(s) hydrophobe(s) supérieure à 0,6 % en poids, par rapport au poids total de la cellulose hydrophobiquement modifiée, et un ou plusieurs alcools gras liquides, ladite ou lesdites celluloses hydrophobiquement modifiées comportant une chaîne principale constituée par un éther de cellulose non ionique sur laquelle est ou sont fixé(s) un
