PROBLEM TO BE SOLVED: To provide an intermediate composition for simply and stably producing an α gel-containing O/W emulsion cosmetic which has a viscosity with a very little variation per hour, and excellent emulsification stability, without using a cooling device having a heavy burden on the cost and environment, and to provide a production method thereof.SOLUTION: The invention relates to an α gel intermediate composition consisting of (A) 20-80 mass% of a mixture in which one or more kinds of higher alcohols with a carbon number 16 or more and an anionic surfactant are mixed at a molar ratio of 3:2-5:1; and (B) 20-80 mass% of a mixture in which one or more kinds of aqueous solvents with an IOB value of 1.5-3.5 and water are mixed at a mass ratio of 5:5-8:2. In 65-85°C, the composition is a liquid consisting of a bi-continuous microemulsion phase or a bi-continuous microemulsion phase in which a lamellar liquid crystal is dispersed, and is a solid in a room temperature. |
