Detergent composition comprising a nonionic surfactant and an anionic polymer; use of said composition for preserving colour

摘要

Cosmetic detergent composition (A) in an aqueous medium comprises non-ionic tensio active agent (5-20 wt.%) (fatty glycerol alcohol, fatty glycerol amide, oxyalkylene vegetable oil, alkyl poly glycosides or N-alkyl glucamine derivative) and cross-linked anionic copolymer of vinylic carboxylic acid (monomer A) and monomer (having at least an unsaturated a,beta -ethylenic) (monomer B) (where the monomer is alkyl compounds ((I), (II) or (III)). Cosmetic detergent composition in an aqueous medium comprises non-ionic tensio active agent (5-20 wt.%) (glycerol fatty alcohol, glycerol fatty amide, oxyalkylene vegetable oil, alkyl poly glycosides or N-alkyl glucamine derivative) and cross-linked anionic copolymer of vinylic carboxylic acid (monomer A) and monomer (having at least an unsaturated a, beta -ethylenic) (monomer B) (where the monomer is alkyl compounds (I), (II) or (III) of formulae CH 2=CXY, CH 2=CH(OCOR 1>) or CH 2=CH 2 or CH 2=CHCH 3 respectively). R : 1-8C alkyl or 2-8C hydroxyalkyl; Ra : H, 1-8C alkyl or 2-8C hydroxyalkyl; and R 1>1-8C alkyl (preferably 1-4C). Provided that when X is H, then Y is -COOR, -C 6H 4Ra, -CN, -CONH 2, -NHCOCH 3, -CONHC(CH 3) 3 or -CON(CH 3) 2); and when X is CH 3, then Y is -COOR, -C 6H 4Ra or -CH=CH 2. An independent claim is also included for a process of cosmetic treatment of the keratinous materials (particularly hair) comprising applying (A) on the materials and eventually rinsing with water.
