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 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.
