Abstract

Cosmetic or pharmaceutical preparations, which contain natural or synthetic oils having ester groups or mineral oils, are characterized by containing a selected organopolysiloxanes with long-chain alkyl or alkoxy groups for improving the spreading behavior of the oils, particularly on the human skin. The organopolysiloxanes are added to the oil in amounts of 0.003 to 20% by weight, based on the total weight of oil and organopolysiloxane.
