Abstract

Abstract The invention concerns a method of homogenizing dispersions of hydrated lipidic lamellar phases and suspensions obtained thereby which can be applied particularly to the making of products intended for cosmetic, pharmaceutical and medical uses. The method consists in dispersing in a dispersion liquid a lipidic phase or a lipidic lamellar phase containing one or several amphiphilic lipids and then in homogenizing the said dispersion by feeding the same under a pressure comprised between 10,000 and 70,000 kPa into a passageway of small width defined between the walls of an orifice and the edges of an obturating element arranged in the section of the orifice adjustably, against the flow of the dispersion.
