Cosmetic compositions containing organic sunscreens along with a
4-substituted resorcinol derivatives of general formula I exhibit improved
storage stability and oxidative stability:
##STR1##
where each R.sub.1 and R.sub.2, independently, represents a hydrogen atom,
--CO--R (acyl group), --COO--R CONHR; where R represents saturated or
unsaturated, linear, branched or cyclic C.sub.1 -C.sub.18 hydrocarbon
groups; and
R.sub.3 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., R.sub.3 constitutes linear or branched chain alkyls, or
(2) a group of the general formula formula (II)
##STR2##
Where X is preferably H, n is 0 to 3 and the dashed lines represents an
optional double bond.
