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.
