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

1
-C
18
烃基;以及
R
3

3
构成直链或支链烷基,或 (2) 通式 (II) 的基团
2
其中 X 最好为 H,n 为 0 至 3,虚线代表任选双键。
