Abstract
Polyorganosiloxanes containing urea groups can be obtained in the form of aqueous dispersions by firstly dissolving them in an organic solvent, then dispersing this solution with water with co-use of auxiliaries, subjecting the mixture to homogenization and then at least partially removing the organic solvent. The aqueous dispersions prepared in this way are suitable as additive for detergents, fabric softeners, haircare compositions, shampoos and for textile finishing.
