Abstract:
The purpose of the present invention is to provide a water-in-oil type cosmetic which ensures emulsion stability in the case where a volatile hydrocarbon oil component is added, has excellent texture such as not leaving a greasy feeling, and is highly compatible with the skin. The present invention relates to a water-in-oil type emulsified cosmetic comprising: (A) 20 to 30 mass % of an oil component; (B) a fatty acid ester having an HLB of 5 to 10; (C) a nonionic surfactant having an HLB of 1 to 4; (D) an organic modified clay mineral; and (E) water, wherein volatile hydrocarbon oil accounts for 10 mass % or more of the oil component (A) and silicone oil is not contained.
