Skin treatment composition containing monoester of citric acid

摘要

A skin treatment composition comprising a physiologically acceptable carrier and 1-35% by weight of a salt of a monoester of citric acid. The skin treatment composition imparts a pleasant smoothness to the skin and may be incorporated in several products to treat skin dryness. The hydrophobic group having an ester linkage to citric acid has 10 to 18 carbon atoms. Monoester of citric acid may be synthesized with low levels of di- and triester by forming citric acid anhydride and reacting this to form the monoester.
