[PROBLEMS] To easily and stably produce an α-gel-containing O / W emulsified cosmetic with very little change in viscosity with time and excellent emulsification stability, without using a cooling device that has a large cost and environmental burden. An intermediate composition for producing the same and a method for producing the same are provided. (A) A mixture in which one or two or more higher alcohols having 16 or more carbon atoms and an anionic surfactant are mixed at a molar ratio of 3: 2 to 5: 1, 20 to 80% by mass. ,as well as, (B) A mixture in which one or more water-soluble solvents having an IOB value of 1.5 to 3.5 and water are mixed at a mass ratio of 5: 5 to 8: 2, 20 to 80% by mass , Consists of At 65-85 ° C., it is a liquid consisting of a bicontinuous microemulsion phase or a bicontinuous microemulsion phase in which lamellar liquid crystals are dispersed, Be solid at room temperature, An α-gel intermediate composition characterized by [Selection] Figure 2 |
