METHOD FOR PRODUCING EMULSION

摘要

The disclosed invention is a method for producing an emulsion, comprising the steps of:
(1) causing water and a water-insoluble substance that is to be emulsified to become freely miscible under conditions of temperature and pressure in the vicinity of the vapor-liquid critical point of water; and
(2) cooling the product comprised of the water-insoluble substance and water solved each other in the presence of a surfactant to obtain a liquid comprised of the water-insoluble substance dispersed in water or a liquid comprised of water dispersed in the water-insoluble substance. The present invention provides a new method for producing emulsions with high efficiency without requiring a long period of processing or a great amount of energy.
