For example, N-(cholesteryloxycarbonyl)-2-aminooctadecane-1,3-diol. The compound of formula I is obtained by reacting the amine functional group of a sphingoid base of formula II with s cholesteryl chloroformate of formula III in the presence of a base in a proper organic solvent. The compound of the formula I is preferably added to cosmetics or compositions for skins in amounts of 0.01-10 wt.%, respectively, to prepare the cosmetics or the compositions for the skins.
