Patent ID: 8246941

Claim:
A detergent and conditioning cosmetic composition, comprising, in a cosmetically acceptable aqueous medium, (A) at least one sulfate or sulfonate anionic surfactant in an amount ranging from 8% to 25% by weight relative to the total weight of the composition, (B) at least one carboxylic anionic surfactant other than surfactant (A) in an amount ranging from 0.5% to 15% by weight relative to the total weight of the composition, (C) at least one amphoteric surfactant in an amount ranging from 1% to 10% by weight relative to the total weight of the composition, and (D) at least one amino silicone, wherein the at least one carboxylic anionic surfactant is chosen from those of formula (1): R 1 —(OC 2 H 4 ) n —OCH 2 COOA (1) wherein: R 1 is chosen from linear or branched C 8 -C 22 alkyl radicals, linear or branched C 8 -C 22 alkenyl radicals, and mixtures thereof; (C 8 -C 9 )alkylphenyl radicals; and R 2 CONH—CH 2 —CH 2 — radicals, wherein R 2 is chosen from linear or branched C 9 -C 21 alkyl radicals and linear or branched C 9 -C 21 alkenyl radicals, n is chosen from integers and decimal numbers (average value) ranging from 2 to 24, and A is chosen from hydrogen, ammonium, Na, K, Li, Mg, monoethanolamine residues, and triethanolamine residues; wherein the at least one sulfate or sulfonate anionic surfactant and the at least one carboxylic anionic surfactant are present in a weight ratio ranging from 2 to 10, wherein the weight ratio of the at least one sulfate or sulfonate anionic surfactant to the at least one amphoteric surfactant ranges from 4 to 10, and wherein the at least one carboxylic anionic surfactant and the at least one amphoteric surfactant are present in a weight ratio ranging from 0.3 to 1.5, and the surfactants are present in the composition in a total amount ranging from 8% to 35% by weight relative to the total weight of the composition.
