The alpha-hydroxy esters are increasingly employed in cosmetic, food, and pharmaceutical formulations as they determine reduced skin-irritant effects in comparison with the respective acids, offering similar hygroscopic, emulsifying, and exfoliating properties. The enzymatic synthesis of lactate esters in nonaqueous systems
