Washing and conditioning cosmetic composition comprising four surfactants and a non-silicone

A cosmetic treatment process for washing and conditioning keratin materials, comprising

• applying to the keratin materials an effective amount of a composition comprising
• at least one anionic surfactant (A) comprising in its structure at least one group chosen from sulfate, sulfonate and phosphate groups,
• at least one carboxylic alkyl ether anionic surfactant (B) other than the at least one anionic surfactant (A),
• at least one surfactant chosen from amphoteric and zwitterionic surfactants (C),
• at least one alkyl(poly)glycoside nonionic surfactant (D),
• at least one non-silicone fatty substance (E), and
• optionally at least one cationic polymer (F), wherein
• the weight ratio of the amount of the at least one anionic surfactant (A) to the amount of the at least one nonionic surfactant (D) has a value ranging from 0.5 to 1.

• at least one surfactant chosen from amphoteric and zwitterionic surfactants (C),
• at least one alkyl(poly)glycoside nonionic surfactant (D),
• at least one non-silicone fatty substance (E), and
• optionally at least one cationic polymer (F), wherein
• the weight ratio of the amount of the at least one anionic surfactant (A) to the amount of the at least one nonionic surfactant (D) has a value ranging from 0.5 to 1.
