Summary:Cosmetic compositions containing a micronized metal oxide along with a 4-substituted resorcinol derivatives of the general formula I exhibit improved storage stability:where each R1 and R2, independently, represents a hydrogen atom, -CO-R (acyl group), -COO-R, CONHR; where R represents saturated or unsaturated, linear, branched or cyclic C1-C18 hydrocarbon groups; andR3 represents (1) an alkyl group, having from 1 to 18 carbon atoms, preferably having from 2 to 12 carbon atoms, with or without substitution of one or more hydrogen atoms of a linear alkyl group with a methyl or ethyl group; e.g., R3 constitutes linear or branched chain alkyls, or (2) a group of the general formula formula (II)Where X is preferably H, n is 0 to 3 and the dashed lines represents an optional double bond.
