    Abstract: The invention relates to a process for the production of sugar surfactant granules in which water-containing sugar surfactant pastes are subjected to granulation in the presence of selected silicon compounds. In the production of such granules, caking problems are frequently encountered in the production units. A process for the production of sugar surfactant granules in which such problems are avoided has now been found. In this process, water-containing pastes of a) alkyl and/or alkenyl oligoglycosides and/or b) fatty acid-N-alkyl polyhydroxyalkyl amides are subjected to granulation in the presence of zeolites and/or waterglasses and optionally dried in a following process step, the granules being powdered with dusts during granulation.
