Patent number: 11771640Abstract: The purpose of the present invention is to provide a water-in-oil type emulsion cosmetic that has a replenishing and smooth feel-of-use, that, once applied, forms a uniform coating, and that can minimize the appearance of skin roughness such as pores while covering discoloration such as spots and freckles, but that does not give an impression of a thick coating. The present invention provides a water-in-oil type emulsion cosmetic characterized by containing (A) 0.1-20 mass % of metallic soap-treated powder, and (B) a water-absorptive polymer having 0.01-2 mass % of a carboxyl group. The (B) water-absorptive polymer having a carboxyl group of this cosmetic preferably can absorb 10-1,000 times its own weight.Type: GrantFiled: March 29, 2019Date of Patent: October 3, 2023Assignee: Shiseido Company, Ltd.Inventors: Shun Kubota, Shoko Ogawa, Ryushi Fukuhara

Patent number: 11712406Abstract: 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.Type: GrantFiled: December 6, 2021Date of Patent: August 1, 2023Assignee: SHISEIDO COMPANY, LTD.Inventors: Shun Kubota, Hideo Hata, Malyn Concina, Michelle Lou, Hideki Takahashi, Julie Shown, Yosuke Ikebe
