Abstract
A novel series of compositions with aqueous chemicals decontamination activity and their uses is described. The preparation of esters of fatty acids with polyols that contain lactic acid is also described. These novel compositions release hydroxy acid and fatty acids slowly into water providing activity over long periods of time with the compounds exhibiting biodegradable characteristics and aiding in the biodegradation of contaminants.
