Abstract: The invention discloses skin treatment compositions consisting essentially of a mixture of ceramides, cholesterol, free fatty acids—the mixture being able to mimic skin identical lamellar structures—and nonionic emulsifiers. These compositions are liquid and pumpable at room temperature which means that they can be incorporated easily into cosmetic formulations with no need for heating. Furthermore, the skin treatment compositions allow the stable inclusion of long-chain ceramides into oil-in-water emulsions as well as into water-in-oil emulsions. Inclusion of short chain ceramides that can act as dermatological regulators did not affect the lamellar lipid organization. The skin treatment compositions are claimed as well as their use in cosmetic and dermatological formulations.

Abstract: The object of the present invention is to provide antifoams which have a good antifoam effect in aqueous dispersions of polymeric organic substances, cause no wetting defects when these dispersions are applied to a surface and at the same time retain their antifoam activity even after prolonged storage at temperatures down to the freezing point.
