发明名称 Sunscreen compositions comprising metal oxide mineral pigments and hydroxyalkylurea compounds
摘要 The invention relates to a composition comprising, in a cosmetically acceptable carrier, a system for screening out UV radiation, characterized in that it contains: (a) at least metal oxide-based mineral pigments, and (b) at least one hydroxyalkylurea of formula (I) below: in which R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3 </SUB>and R<SUB>4 </SUB>each independently represent a hydrogen atom, a C<SUB>1</SUB>-C<SUB>4 </SUB>alkyl group or a C<SUB>2</SUB>-C<SUB>6 </SUB>hydroxy-alkyl group that may contain from 1 to 5 hydroxyl groups, at least one of the radicals R<SUB>1</SUB>-R<SUB>4 </SUB>representing a hydroxyalkyl group, and also a salt, solvate or isomer thereof, said composition containing no kojic dipalmitate. The invention also relates to the use of a hydroxyalkylurea of formula (I) in a composition comprising, in a cosmetically acceptable carrier, at least metal oxide-based mineral pigments, for reducing, or even eliminating, the whitening effect on the keratin material after application.
