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, and wherein 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.
