Claim 0:
1. A liquid crystal emulsification method comprising:
in a water-in-oil type pre-emulsion production unit a water-in-oil type pre-emulsion is produced, then transferred to a liquid crystal phase formation unit, wherein a liquid crystal phase in a transition state between a water-in-oil type pre-emulsion and an oil-in-water type emulsion is formed, then transferred to the oil-in-water type emulsion production unit, wherein an oil-in-water type emulsion is produced,
characterized in that, adding a moisture content and a silicone composition as an oil content at a predetermined ratio to a nonionic surfactant having an HLB falling within a predetermined range which represents a balance of hydrophilicity and lipophilicity, of 8.0 to 19.0; setting a temperature during formation of a dispersion or an emulsion to a predetermined temperature by cooling to a temperature selected from a temperature range of −40° C. to −5° C. and obtaining a final oil-in-water type emulsion with a particle diameter of 0.20 to 0.22 μm, and a predetermined shear energy is applied according to the selected temperature to adjust a lamellar liquid crystal having a regular molecular arrangement in which the oil content and the moisture content are alternately arranged in a bilayer membrane formed from the surfactant.
