ABSTRACT OF THE DISCLOSURE A method for preparing a pulverulent mixture of amphi- philic lipidic constituents and possibly for hydrophobic con- stituents, and a method for producing hydrated lipidic lamellar phases from the said pulverulent mixture. The amphiphilic lipidic constituents and the hydrophobic constituents are dis- solved in a non-aqueous solvent and the solution is then atomized in a flow of gaseous fluid to produce the pulverulent mixture. The mixture is a homogeneous and very fine powder which can be very easily dispersed in a suitable aqueous dispersion medium to produce either slightly hydrated lipidic lamellar phases or highly hydrated lipidic lamellar phases such as liposomes useful in the pharmaceutical and cosmetic fields.
