The preparation of alkyl oligoglycosides by trans- glycosidation of C2 to C6 alkyl glycosides using C8 to C20 fatty alcohols is improved by the fact that the fatty alcohol is preheated to at least 80°C, it is mixed with the alkyl glycoside, then the reaction is performed at a pressure of 1.1 to 10 bar and C2 to C6 alcohol is flashed off under vacuum after the reaction. Products having a good colour are obtained. Encrustation and cracking in the equipment do not occur.
