摘要:
The present invention provides a simple and economical production method, without using a large amount of thickeners, of a high-viscosity O/W cream. The production method comprising: emulsifying, at 70° C. or higher, an oil phase with a water phase to prepare an O/W emulsified part, wherein the oil phase comprises (A) a nonionic surfactant, (B) a linear higher alcohol that has 16 or more carbon atoms and can form an α-gel in water with (A), and (C) an oil component, and the water phase comprises (D) water; cooling the emulsified part while being stirred; and stopping the stirring at the peak temperature or higher in a temperature range wherein the oil phase forms an α-gel in the water phase, but lower than 70° C. The peak temperature is the exothermic peak measured by DSC of the emulsified part. The viscosity of the O/W cream measured with a B-type viscometer at 30° C. is preferably 8,000 mPa·s or higher.
