Abstract: A method of preparing a fine oil-in-water emulsion comprising an oil phase based on silicone and/or hydrocarbon oils, in which the oil phase particles have an average particle size of 150 nm or less. The emulsion is stabilized by a carboxy-modified silicone in combination with a C16 to 22 higher alcohol; a nonionic surfactant having a POE chain and an HLB of 5 to 10; and a dihydric glycol. The emulsions can be prepared without the use of a high-pressure emulsifying apparatus.

Abstract: The present invention provides an α-gel forming composition and an α-gel composition that uses an α-gel formation composition that is highly stable and that does not become colored or deposit crystals, etc. over time. An α-gel composition includes (A) 25-50 mass % of one or more higher aliphatic alcohol and/or higher fatty acid has 16 or more carbons, (B) 40-70 mass % of a specific polyoxyethylene sterol ether, and (C) 5-20 mass % of a specific polyoxyethylene dialkyl ester and/or ether. The α-gel composition is generated by adding water.
