A process for preparing free-flowing washing and cleaning agents granules and / or partial granules

Pourable washing and cleaning granulates and/or partial granulates can be manufactured by simultaneously dehydrating and granulating aqueous alkyl and/or alkenyl oligoglycoside pastes in the presence of anionic and/or non-ionic surface-active agents and/or standard washing and cleaning substances in a turbo-dryer with incorporated rotating elements. The products are brightly coloured, are stable in storage and have a narrow grain size distribution.
