Abstract

Provided are alkyl lactyllactate compositions that can be prepared from (1) lactide or alternatively lactic acid, and (2) a hydroxyl containing compound such as an alcohol, preferably a fatty alcohol or an alkoxylated alcohol, with (3) an acid catalyst. Preferably, the fatty alcohol contains from about 6 to 18 carbon atoms, such as lauryl alcohol. The alkyl lactyllactates can be used as surfactants, emulsifiers, skin feel agents, film formers, thickeners, rheological modifiers, etc., for personal care and other application areas. Compositions containing at least one alkyl lactyllactate are also provided. The compositions can further contain at least one surfactant.
