This article reviews the work on the technique for preparing a variety of liquid/liquid type multiple-phase dispersions. The major contents are divided into three sections: principle for obtaining multi-lamellar and single compartment lipomes, two-step procedure for emulsification in preparing the water-in-oil-in-water (W/O/W) type multiple-phase emulsions by use of liquid paraffine and ordinary emulsifying agents, and application of the two-step procedure for providing liposome-like lipid vesicle suspensions composed of the mixture of purified soy lecithin and Span 80.
