ABSTRACT:
This invention relates to an oil-in-water-in-oil (O/W/O) type multiple emulsion which contains an inner oil phase, a water phase, and an outer oil phase. The inner oil phase is first dispersed in water to form an oil-in-water (O/W) emulsion. Then, the O/W emulsion is further dispersed in the outer oil phase to form the O/W/O type multiple emulsion. The outer oil phase contains an organophilic clay mineral, which can effectively prevent the inter-mixing of the inner oil phase with the outer oil phase, thus, producing an O/W/O type multiple emulsion with excellent storage stability. Upon the using of an oil-soluble compound in the inner oil phase, this multiple emulsion system can prevent the oil-soluble compound from being oxidized. In addition, since different kinds of oils can be selected for the making of the inner and outer oil phases, respectively, the O/W/O type multiple emulsion system allows one to present two different kinds of oils, which have different properties independent from each other, in one emulsion system.
