摘要:
The present invention has an object to provide a flaky particulate material giving skin an excellent smoothness, which is free from whitening problem upon use thereof owing to its high transparency. The present invention also has another object to provide a cosmetic composition containing the flaky particulate material. The present invention relates to flaky particulate material, which has an average coefficient of friction is not more than 0.50, and a total light transmittance is not less than 85%. A particle in the flaky particulate material comprises a substrate particle made of one material selected from the group consisting of mica, a synthetic mica, sericite, talc, barium sulfate and aluminum oxide. The present invention provides a flaky particulate material that gives skin excellent smoothness, a natural tone, and a matt appearance. The flaky particulate material of the present invention gives a cosmetic composition which provides great comfort of use, and an excellent appearance.

摘要:
A method for producing a metal composite oxide, the method including steps of: preparing a slurry by mixing different kinds of metal compounds in a powder form, a dispersion medium, and a dispersant, and baking the different kinds of metal compounds after the dispersion medium in the slurry is removed. The slurry further includes a polyalkylene oxide having a viscosity average molecular weight of 150,000 or more. The slurry has a viscosity of 10 mPa·s to 2000 mPa·s, the viscosity being measured using a B-type viscometer under conditions of a temperature of 23° C. to 27° C. and a rotation rate of 60 rpm. According to the production method, a slurry in which different kinds metal compound powders are uniformly dispersed and a precipitate is unlikely to be formed can be obtained. Therefore, a metal composite oxide having a desired composition can be obtained.
