Multiple emulsion having a form of water/oil/water phase and process for preparation thereof, and multiple emulsion type cosmetics

摘要

A multiple emulsion having a dispersing form of water- phase/oil- phase/water-phase and a process for preparation thereof, and a multiple emulsion type cosmetics utilizing said multiple emulsion as a fundamental form, said multiple emulsion consisting of a dispersed phase and a dispersion medium, of which the dispersed phase is a water-in-oil type emulsion formed by dispersing water phase into oil phase which consists of an oil component and a oil-soluble emulsifier having such a hydrophile- lipophile balance that the oil component forms a dispersion medium of the water-in-oil type emulsion, and of which the dispersion medium is an aqueous solution which contains an water-soluble emulsifier having such a hydrophile-lipophile balance that the oil component forms a dispersion medium of an oil-in-water type emulsion and having such concentration that the oil-soluble emulsifier does not dissolved therein.
