Abstract

A process for manufacturing alkyloligoglycosides. Alkyloligoglycosides nand alkylglycosides having alkyl groups with 8 to 24 carbon atoms, which are of interest in home economics and in the cosmetics industry, can be manufactured by glycosidation and transglycosidation. Light-colored alkyloligoglycosides and alkylglycosides are manufactured from saccharides and alcohols by glycosidation and transglycosidation with the addition of salts of inorganic acids, or polybasic saturated carboxylic acids, and by bleaching of the final products with peroxides.
