Detergent cosmetic composition comprising at least four surfactants, at least one cationic polymer and at least one zinc salt

A process for washing and/or cleansing keratin fibers, comprising

• applying to the keratin fibers a cosmetic composition comprising:
• at least one anionic surfactant (A) comprising, in its structure, at least one group chosen from sulphate, sulphonate, and phosphate groups,
• at least one carboxylic anionic surfactant (B) other than the at least one anionic surfactant (A),
• at least one surfactant (C) chosen from amphoteric and zwitterionic surfactants,
• at least one alkyl(poly)glycoside non-ionic surfactant (D),
• at least one cationic polymer (E),
• at least one zinc salt (F), and
• optionally at least one UV-screening agent (G), and
• further wherein the weight ratio of the total amount of the surfactants (A), (B), (C), and (D) to the amount of zinc element of the at least one zinc salt has a value of less than 30;
• optionally kneading the hair, and rinsing the hair.

A process for protecting the color of keratin fibers from sunlight and/or repeated washing, comprising applying to the keratin fibers a cosmetic composition comprising:

• at least one anionic surfactant (A) comprising, in its structure, at least one group chosen from sulphate, sulphonate, and phosphate groups,
• at least one carboxylic anionic surfactant (B) other than the at least one anionic surfactant (A),
• at least one surfactant (C) chosen from amphoteric and zwitterionic surfactants,
• at least one alkyl(poly)glycoside non-ionic surfactant (D),
• at least one cationic polymer (E),
• at least one zinc salt (F), and
• optionally at least one UV-screening agent (G), and
• further wherein the weight ratio of the total amount of the surfactants (A), (B), (C), and (D) to the amount of zinc element of the at least one zinc salt has a value of less than 30;
• optionally kneading the hair, and rinsing the hair.

A multi-compartment kit for dyeing keratin fibers, comprising:

• at least one compartment comprising at least one dyeing composition chosen from one-part and two-part oxidation dye and direct dye compositions;
• and at least one compartment comprising a cosmetic composition, wherein the cosmetic composition comprises:
• at least one anionic surfactant (A) comprising, in its structure, at least one group chosen from sulphate, sulphonate, and phosphate groups,
• at least one carboxylic anionic surfactant (B) other than the at least one anionic surfactant (A),
• at least one surfactant (C) chosen from amphoteric and zwitterionic surfactants,
• at least one alkyl(poly)glycoside non-ionic surfactant (D),
• at least one cationic polymer (E),
• at least one zinc salt (F), and
• optionally at least one UV-screening agent (G), and
• further wherein the weight ratio of the total amount of the surfactants (A), (B), (C), and (D) to the amount of zinc element of the at least one zinc salt has a value of less than 30.
