Document Type and Number:
WIPO Patent Application WO/2017/126252
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a water-in-oil type emulsion cosmetic material in which a decrease in viscosity is not caused to occur even when a large quantity of perfume is blended therein and which exhibits excellent stability. The present invention relates to a water-in-oil type emulsion cosmetic material which contains (a) 5-15 mass% of perfume, (b) 1.5-3 mass% of dimethyldistearyl ammonium hectorite and (c) a non-ionic surfactant, wherein the non-ionic surfactant (c): contains 2-10 mass% of (c1) a polyether-modified silicone having a hydrocarbon branch chain having 12-22 carbon atoms; and may contain no more than 10 mass% of (c2) a polyether-modified silicone not having an alkyl chain. The ratio of the overall blending quantity of component (c1) and component (c2) relative to component (b) is 2 or higher, the ratio of the overall blending quantity of component (c1) and component (c2) relative to component (a) is 0.8 or higher, the overall blending quantity of component (c1) and component (c2) is 4 mass% or more, the ratio of the blending quantity of component (c1) relative to that of component (c2) is 0.8 or higher, and the rheometer hardness of the cosmetic material is 6 or higher.
