Anhydrous pourable sugar tenside powders are obtained by the treatment of aqueous preparations containing (a1) alkyl and/or alkenyl oligoglycosides and/or (a2) fatty acid-N-alkylpolyhydroxyalkylamides with superheated steam at a temperature of 100-225 DEG C and removal of the dried product. The products thus obtained have excellent smell and taste characteristics and can be used in the production of surface active substances such as toothpastes and synthetic soaps. |
