Abstract

A process is described for preparing alkyl glycosides by reacting reducing saccharides with dialkyl sulfate whose alkyl groups contain at least 6 carbon atoms, in a molar ratio of saccharides to dialkyl sulfate of 1:1 to 1:5, the reaction mixtures, which contain alkyl monoglycosides and alcohol sulfates as essential constituents, being used as surfactants, preferably in detergents and cleaning agents.
