Abstract

Disclosed are novel polyhydric alcohol partial esters of polycarboxylic acids from Diels-Alder adducts of maleic anhydride and a straight chain unsaturated carboxylic acid having ten to twenty-five carbon atoms. The partial esters can be subsequently sulfated. The polyhydric alcohol can be a mono- or disaccharide such as sucrose or mannose. The partial esters are surfactants which are dermatologially acceptable and useful in personal products and skin-care products.
