摘要

Cosmetic or dermatological formulations contain: (a) an effective amount of surfactant(s) selected from alkylglucosides (I) with a linear or branched 4-24 carbon (C) alkyl group; (b) optionally containing 4-24 C alkanol(s) (II); and (c) substance(s) selected from flavones, flavanones and flavonoids. Cosmetic or dermatological formulations contain (a) an effective amount of surfactant(s) selected from alkylglucosides with a linear or branched 4-24 carbon (C) alkyl group, of formula (I), (b) optionally containing 4-24 C alkanol(s) of formula (II), and (c) substance(s) selected from flavones, flavanones and flavonoids: R = linear or branched 4-24 C alkyl; D.P = an average degree of glycolylization of up to 2 An Independent claim is also included for the use of (I) and optionally (II) for stabilizing substance(s) selected from flavones, flavanones and flavonoids against chemical degradation, especially photochemical and/or oxidative degradation.
