摘要

Use of a cosmetic preparation containing glycyrrhizin and/or glycyrrhetinic acid, one or more interface-active substance (a) such as glucose derivative (I) and one or more interface-active substance (b), such as ester compound (II) for strengthening the pigmentation of human skin. Use of a cosmetic preparation containing glycyrrhizin and/or glycyrrhetinic acid, one or more interface-active substance (a) such as glucose derivative of formula (I) and one or more interface-active substance (b) such as ester compound (II) of formula R 3-O-(CH 2-CH-(O-R 4)-CH 2-O) n-R 5, for strengthening the pigmentation of human skin. R : 1-24C alkyl; R 1H or 1-24C alkyl; R 2H or 1-24C acyl; R 3-R 5H or optionally saturated 8-24C fatty acid, in which up to three aliphatic H atoms are substituted by OH; and n : 2-8. Where the group O-R 1 is present in alpha and beta position. [Image] ACTIVITY : Antiinflammatory; Dermatological. MECHANISM OF ACTION : None given.
