Abstract
Active substance combinations of (a) one or more surface-active substances selected from the group comprising glucose derivatives, (b) one or more surface-active substances selected from the group comprising glycerol monocarboxylic or dicarboxylic acid monoesters and (c) one or more water-soluble, cosmetically or pharmaceutically acceptable UV filters.
Claims19
Cosmetic or dermatological compositions comprising
- (a) one or more surface-active glucose derivatives of the formula ##STR24## in which R is a branched or unbranched alkyl radical having 1 to 24 carbon atoms, R.sub.1 is either a hydrogen atom or a branched or unbranched alkyl radical having 1 to 24 carbon atoms and R.sub.2 is either a hydrogen atom or a branched or unbranched acyl radical having 1 to 24 carbon atoms,
- (b) one or more surface-active glycerol monocarboxylic or dicarboxylic acid monoesters of the formula ##STR25## in which R.sub.3 is a branched or unbranched acyl radical having 6-24 carbon atoms, and
- (c) one or more water-soluble, cosmetically or pharmaceutically acceptable UV filters.
A method of protecting skin from the effects of damaging UV light comprising applying to the skin a protective amount of a cosmetic or dermatological formulation comprising
- (a) one or more surface-active glucose derivatives of the formula ##STR26## in which R is a branched or unbranched alkyl radical having 1 to 24 carbon atoms, R.sub.1 is either a hydrogen atom or a branched or unbranched alkyl radical having 1 to 24 carbon atoms and R.sub.2 is either a hydrogen atom or a branched or unbranched acyl radical having 1 to 24 carbon atoms,
- (b) one or more surface-active glycerol monocarboxylic or dicarboxylic acid monoesters of the formula ##STR27## in which R.sub.3 is a branched or unbranched acyl radical having 6-24 carbon atoms, and
- (c) one or more water-soluble, cosmetically or pharmaceutically acceptable UV filters, said formulation being optionally in the form of a foam.
A cosmetic or dermatological formulation for protecting skin from the effects of damaging UV light comprising a skin protective amount of a composition comprising
- (a) one or more surface-active glucose derivatives of the formula ##STR28## in which R is a branched or uubranched alkyl radical having 1 to 24 carbon atoms, R.sub.1 is either a hydrogen atom or a branched or unbranched alkyl radical having 1 to 24 carbon atoms and R.sub.2 is either a hydrogen atom or a branched or unbranched acyl radical having 1 to 24 carbon atoms,
- (b) one or more surface-active glycerol monocarboxylic or dicarboxylic acid monoesters of the formula ##STR29## in which R.sub.3 is a branched or unbranched acyl radical having 6-24 carbon atoms, and
- (c) one or more water-soluble, cosmetically or pharmaceutically acceptable UV filters, said formulation being optionally in the form of a foam.
