PROCESS FOR OBTAINING STABLE DISPERSIONS IN AN AQUEOUS PHASE OF AT LEAST A WATER IMMISCIBLE LIQUID PHASE, AND CORRESPONDING DISPERSIONS |
摘要 |
A process for the preparation of a stable emulsion of at least one water-immiscible liquid phase L in an aqueous phase D is described which comprises mixing the liquid phase or phases L with a dispersion of spheres in an aqueous phase D, the spheres having an average diameter of 0.025 to 5 microns and consisting of substantially concentric lipid laminae encapsulating an aqueous phase E between them, the lipid or lipids constituting the laminae being ionic or nonionic amphiphilic substances capable of forming a lamellar phase in water, and subjecting the whole to mechanical agitation so as to disperse the phase (or phases) L in the phase D in the form of droplets having an average diameter of 0.1 micron to a few microns. |
