  • Method for producing emulsion
    Patent number: 10967336
    Abstract: The disclosed invention is device for preparation of an emulsion and a method for producing an emulsion. The method comprises 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 device and a new method for producing emulsions with high efficiency without requiring a long period of processing or a great amount of energy.
