摘要：
Cosmetic preparations which contain (a) an ester of a hydroxycarboxylic acid and an alk(en)yl oligoglycoside, and (b) a UV protection factor; are described. The correspond to the general formula (I): wherein X represents a hydrogen or a —CH2COOR3 substituent, Y represents a hydrogen or a hydroxyl substituent, R1, R2, and R3 each independently represents a substituent selected from the group consisting of hydrogen, alkali metals, alkaline earth metals, ammonium, alkyl ammoniums, hydroxyalkyl ammoniums, glucammonium, and residues of alk(en)yl oligoglycosides; wherein at least one of R1, R2 and R3 represents a residue of an alk(en)yl oligoglycosides, and with the proviso that, where X represents a —CH2COOR3 group, Y is hydrogen.
