Abstract

Powder-form preparations of surface-active alkyl glycosides contain 5 to 65% by weight of a surface-active alkyl glycoside and 35 to 95% by weight of an inert inorganic support. They are produced by mixing the crude product obtained in the industrial production of the alkyl glycosides with water and an inorganic particulate support, for example silica, chalk or sodium chloride, and drying the resulting mixture. Preferred powder-form preparations contain 20 to 50% by weight of the alkyl glycoside and 50 to 80% by weight of an inert inorganic support.
