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 oil and (b) non-volatile hydrocarbon oil in a combined amount of 40% by mass or more with respect to the total oil content, wherein the blending ratio of (b) non-volatile hydrocarbon oil to (a) volatile hydrocarbon oil, [(b)/(a)], is within a range of 0 to 2.5, and the powder comprises a powder having a surface hydrophobized by a treatment with a metallic soap consisting of a higher fatty acid and a divalent metal or a composite treatment with a higher fatty acid and a divalent metal hydroxide.
