    Abstract: Prepn. of stable dispersions of at least one water-immiscible liq. (I) in an aq. medium (II) is carried out by (a) forming in the aq. medium a dispersion of "spherules" having an av. dia. of 0.025-5 microns and comprising an aq. phase (III) encapsulated between concentric layers of an ionic or nonionic amphiphilic material (IV) capable of forming a lamellar phase in water; (b) mixing the dispersion with (I); and (c) agitating the mixt. to disperse (I) in the aq. medium in the form of droplets with an av. dia. between 1 and a few microns. The process can be used to blood substitutes from perfluorinated cpds. or to prepare dispersions of intestinal lubricants, textile lubricants, foam inhibitors, cleansing agents, coating compsns. etc. The spherules stabilise the dispersion and are themselves stabilised by the droplets of (I).
