Cosmetic composition comprising spiculisporic acid and at least one surfactant

A cosmetic composition comprising, in a physiologically acceptable medium:

• an aqueous phase,
• spiculisporic acid,
• at least one non-sulfate and non-sulfonate surfactant selected from the group consisting of
• an anionic surfactant selected from the group consisting of (C6-C30)acylaminoacids, salts thereof and mixtures thereof,
• an amphoteric surfactant selected from the group consisting of:
• (C8-C20)alkylbetaines, sulfobetaines, (C8-C20)alkylsulfobetaines, (C8-C20)alkylamido(C1-C6)alkylbetaines, (C8-C20)alkylamido(C1-C6)alkylsulfobetaines, amino acids, (C8-C20)alkyl polyaminocarboxylates, (C8-C20)alkylamphoacetates, (C8-C20)alkylamphodiacetates, lecithins, salts thereof, and mixtures thereof, and
• a non-ionic surfactant selected from the group consisting of (C6-C30)alkyl polyglucosides, (C6-C30)alkylpolypentosides, (C6-C30)alkylpolyxylosides, maltose (C6-C30)esters, sucrose (C6-C30)esters, polyglycerol (C6-C30)fatty acids, oxyalkylene sugar esters, esters of (C6-C30)fatty acid and polyethylene glycol, esters of (C6-C30)fatty acid and sorbitan, ethyl-2 hexyl oxy-carbonyl N-methyl glucamine, and mixtures thereof;
• and
• at least one base selected from the group consisting of inorganic bases and basic amino acids, wherein the ratio R1 of the number of moles of base over the number of moles of spiculisporic acid is strictly greater than 1, and wherein the ratio R2 of the mass of spiculisporic acid over the mass of said surfactant is from 1 to 12.5;
• and wherein the composition does not include a surfactant comprising a sulfate and/or a sulfonate group.
