Cosmetic composition comprising a combination of surfactants of carboxylate, acylisethionate and alkyl(poly)glycoside type

A cosmetic composition comprising:

• at least one anionic surfactant of carboxylate type, chosen from the compounds of formula (I):
• R—(OCH2CH2)nW—(CHY1)p-COOX (I)
• wherein:
• Y1 is chosen from a hydrogen atom, a (CH2)qCOOX group, or a hydroxyl group;
• W is chosen from an oxygen atom, a (O-Glu-O)r-(COCH(Y2)-(C(OH)COOX)t)s group, or a CO—NR1 group;
• Y2 is chosen from a hydrogen atom or a hydroxyl group;
• R1 is chosen from a hydrogen atom or a methyl group;
• X is chosen from a hydrogen atom, an ammonium ion, an ion derived from an alkali metal or an alkaline-earth metal, or an ion derived from an organic amine;
• R is chosen from a linear or branched alkyl group comprising from 7 to 29 carbon atoms, from 9 to 21 carbon atoms, or from 11 to 17 carbon atoms, or a linear alkyl group comprising 11 carbon atoms;
• Glu represents a divalent radical derived from glucopyranose wherein two hydroxyl groups are removed;
• p is equal to 0 or 1;
• q is an integer ranging from 1 to 10;
• n is an integer ranging from 0 to 50;
• r is a number ranging from 1 to 10;
• s is equal to 0 or 1;
• t is equal to 0 or 1;
• wherein the anionic surfactant is present in an amount greater than or equal to about 3% by weight, relative to the total weight of the composition,
• at least one anionic surfactant of (C8-C22) acylisethionate type, and
• at least one nonionic surfactant of alkyl(poly)glycoside type.

A process for treating or washing keratin materials, the process comprising:

• at least one nonionic surfactant of alkyl(poly)glycoside type;
• optionally working the composition into a lather;
• and
• after an optional leave-on time, rinsing the keratin materials.
