Abstract
Glycosiduronic acids, such as alkyl glycosiduronic acids or alkenyl glycosiduronic acids, which may be used in the preparation of surfactant compositions, such as detergents and cleansers, are prepared by reacting an oxidized mono-, oligo-, or polysaccharide with up to 10 monomer units with one or more fatty alcohols having 8-22 carbon atoms in the presence of a catalyst, preferably in bulk, and after acetalization removing the excess alcohol. Preferably the oxidized mono-saccharide used is glucuronic acid and/or glucuronic acid-3,6-lactone.
