Abstract:
An oil-in-water type emulsified cosmetic and a method of making can be prepared in a system not containing a silicone and is surprisingly produced without a wet-type dispersion apparatus by using a specific combination of the oil component constituting the oily phase and a hydrophobizing agent for a hydrophobized powder. The composition includes an aqueous phase; an oily phase dispersed in the aqueous phase; and a powder dispersed in the oily phase. The oily phase comprises a volatile hydrocarbon in oil in a combined amount of 40% by mass or more with respect to the total oil content. The powder has a surface hydrophobized by treatment with a metallic soap consisting of a higher fatty acid and a divalent metal, or by a composite treatment with a higher fatty acid and a divalent metal hydroxide.
