摘要

The invention relates to aqueous cosmetic products on the basis of a mild tenside for treating hair or the skin which contain: as the tenside at least one ester of a hydroxy-substituted bi- or tricarboxylic acid (A) of the general formula (I), wherein X is H or a -CH2COOR group, Y is H or -OH with the proviso that Y is H if X is -CH2COOR, R, R?1 and R2¿ are independently a hydrogen atom, an alkali metal atom or alkaline earth atom, an ammonium group, the cation of an ammonium-organic base or a group Z which stems from a polyhydroxylated organic compound that is selected from the group consisting of etherified (C¿6?-C18)-alkyl polysaccharides with 1 to 6 monomeric saccharide moieties and etherified aliphatic (C6-C16)-hydroxyalkyl polyols with 2 to 16 hydroxyl groups, with the proviso that at least one of the groups R, R?1 or R2¿ is a group Z, and at least one active substance (B) that has preservative properties and that is selected from the group of benzoic acid, saturated or unsaturated carboxylic acids and ketocarboxylic acids, their derivatives and their physiologically acceptable salts, with the proviso that the pH of the product ranges from 4 to 5.5. The inventive cosmetic products are characterized in that they are exceptionally mild and are excellently preserved.
