Abstract
Abstract A branched fatty acid cholesterol ester represented by the formula (I): <IMAGE> (I) where, R is a saturated aliphatic hydrocarbon group having a total of 11 to 23 carbon atoms and including at least one alkyl substituent group attached on the main chain inbetween the carboxyl-bonding position and the center of the main chain; and cosmetic compositions containing the same are disclosed.
