Abstract: The present invention provides an intermediate composition enabling to prepare easily and steadily an α-gel-containing O/W emulsion cosmetic that has a very small viscosity change over time and is excellent in emulsion stability, without using a cooling device that has a heavy burden on cost and the environment, and a production method thereof.An α-gel intermediate composition consisting of (A) 20 to 80 mass % of a mixture containing one or more higher alcohols having 16 or more carbon atoms and an anionic surfactant in the mole ratio of 3:2 to 5:1, and (B) 20 to 80 mass % of a mixture containing one or more water-soluble solvents having the IOB value of 1.5 to 3.5 and water in the mass ratio of 5:5 to 8:2, andwherein the composition is a liquid consisting of a bicontinuous microemulsion phase or a lamellar liquid crystal-dispersed bicontinuous microemulsion phase at 65 to 85° C. and a solid at room temperature.

Abstract: Provided is a cosmetic having a unique soft and springy feeling in use, capable of stably formulating therein a UV protector, and providing a light feeling in use such that the cosmetic is separated into pieces when applied to the skin. The present invention relates to a cosmetic characterized by comprising (A) a (meth)acrylic acid/an alkyl (meth)acrylate/a (meth)acrylic acid-POE monoalkyl ether ester copolymer, (B) a UV protector, (C) a nonionic surfactant, and (D) a higher alcohol.

Abstract: An object to be solved by the present invention is to provide a composition for forming α-gel which has a high stability with no color development or crystal deposition over time, and a α-gel composition using the same.
The α-gel composition comprises: (A) 25 to 50% by mass of 1 or more higher aliphatic alcohols having 16 or more carbon atoms and/or higher fatty acids; (B) 40 to 70% by mass of specific polyoxyethylene sterol ether, and (C) 5 to 20% by mass of specific polyoxyethylene dialkyl ester and/or ether, and is generated by adding water.

Abstract: The present invention addresses the problem of providing a ripple-phase-containing composition, an α-gel formation composition, and an α-gel composition that uses the α-gel formation composition, wherein said compositions are highly stable, do not deposit crystals, become more viscous over time, and, when used in a preparations for external use, are refreshing during application and have high skin-moisturizing action after application. A gel composition that includes a polyoxyethylene dialkyl ester and/or a polyoxyethylene dialkyl ether, a polyoxyethylene alkyl ester and/or a polyoxyethylene alkyl ether, and, preferably, a polyoxyethylene sterol ether and water.
