A novel alcohol-modified silicone ester derivative of the following formula (I): ##STR1## wherein R is a saturated or unsaturated, linear, branched or cyclic aromatic residual or hydrocarbon group; a, b and c are numbers which sum falls in the range from 0 to 130; d is a number lying between 0 and 1; and 1, m and n are numbers which sum falls in the range from 0 to 6. Cosmetic compositions containing the above silicone ester derivative (I) were also disclosed. The silicone ester derivative (I) is useful as a cosmetic ingredient due to the capability of improving feel on use.

Alcohol-modified silicon ester derivative and cosmetic composition

A composition for external application comprising a tricyclic saturated hydrocarbon represented by formula (I) is disclosed. ##STR1## wherein R.sup.1 and R.sup.2 may be the same or different and independently represents a hydrogen atom or a methyl group and R.sup.3 represents an alkyl group having 2-3 carbon atoms. The compositions for external application of the present invention exhibit an excellent moisture-retention effect and impart moistened feel without sliminess and irritation to the skin. They are thus useful as skin cosmetics, hair cosmetics, medical compositions for external application, and the like.
