Oil-in-water emulsions with lamellar, liquid crystal phases contain a cosmetic oil or fat component, a hydrophile emulsifier and a lipophile co-emulsifier which is a lipid of the formula R1-O-R2, in which R1 stands for a primary, linear alkyl group, alkenyl group or acyl group with 20 to 30 C-atoms and R2 stands for hydrogen or a hydroxyalkyl group, a hydroxyalkoxyalkyl group or a polyhydroxyalkyl group. Behenyl alcohol is preferably used as a lipophile co- emulsifier. The emulsions enhance the lamellarity and the degree of order of the epidermal lipid structures of the skin.
Des émulsions du type huile dans l'eau à phases de cristaux liquides lamellaires renferment un composant huileux ou gras cosmétique, un émulsifiant hydrophile et un co-émulsifiant lipophile qui est un lipide de la formule R?1¿-O-R?2¿, dans laquelle R?1¿ désigne un groupe alkyle, alcényle ou acyle primaire linéaire de 20 à 30 atomes de carbone, et R?2¿ désigne l'hydrogène ou un groupe hydroxyalkyle, hydroxyalkoxyalkyle ou polyhydroxyalkyle. De préférence, on utilise l'alcool béhénylique comme co-émulsifiant lipophile. Les émulsions augmentent la lamellarité et le degré de succession des structures lipidiques épidermiques de la peau.
