Abstract

The invention relates to organomodified additives, emulsifiers, dispersants and/or active nourishing ingredients present in the silicon part of branched siloxane block copolymers, to the use thereof, in particular for producing cosmetic, dermatological or pharmaceutical formulations as well as care and cleansing products, and to the preparations as such. Specifically the invention relates to branched polysiloxanes having trifunctional T units as well as polyether groups, alkyl radicals of more than 7 carbon atoms or multi-hydroxy functional radicals.
