摘要:
The purpose of the present invention is to provide an oil-in-oil emulsified cosmetic having exceptional transfer resistance after application, luster, excellent spread during application, and especially exceptional cosmetic durability. The present invention pertains to an oil-in-oil emulsified cosmetic characterized by containing (a) 5-80 mass % of a nonvolatile hydrocarbon oil and/or nonvolatile ester oil, (b) 1-70 mass % of a nonvolatile silicone oil, and (c) 2-12 mass % of a spherical powder having an average particle size of 1-10 μm, the oil-in-oil emulsified cosmetic moreover being characterized in that the (a) nonvolatile hydrocarbon oil and/or nonvolatile ester oil and the (b) nonvolatile silicone oil separate when mixed at 25° C. The blend ratio (mass ratio) of the (a) nonvolatile hydrocarbon oil and/or nonvolatile ester oil and the (b) nonvolatile silicone oil is preferably (a)/[(a)+(b)]=0.4-0.8.
