Abstract: Provided is a cosmetic composition containing metal oxide particles having improved dispersibility. A cosmetic composition contains metal oxide particles with an average particle diameter of 1 ?m or less and lepidocrocite-type platy titanate particles with an average unrolled diameter of 0.1 ?m to 10.0 ?m and an average thickness of 0.1 ?m to 4.0 ?m and the titanate particles are at least one selected from titanates expressed by chemical formulae K0.5-0.7Li0.27Ti1.73O3.85-3.95, K0.2-0.7Mg0.4Ti1.6O3.7-3.95, and K0.2-0.7Li0.27-(2x/3)MgxTi1.73-(x/3)O3.7-3.95 [where 0.004?x?0.4].

Abstract: Sodium hexatitanate having a mean particle diameter in the range of 2-5 ?m and an indeterminate shape, and is either obtained by firing a milled mixture obtained as a result of mechanochemical milling of a titanium source and a sodium source or prepared from sodium trititanate obtained by firing a milled mixture obtained as a result of mechanochemical milling of a titanium source and a sodium source.

Abstract: The present invention attains a microwave absorber attachment in a readily, rapidly and stable manner. According to the microwave absorber attaching method and structure of the present invention, a plurality of ferrite plates 4 are bonded to a shield plate 2 at an installation place such as the ceiling, a wall, the floor or the like; the base portion of a support rod 6 is connected to the ferrite plates 4, causing the support rod 6 to project therefrom; a microwave absorber 1 is placed with its base portion placed along the ferrite plates 4; the support rod 6 passes through a tip opening 11 of the microwave absorber 1, causing the support rod 6 to project therethrough; a covering tray 8 allows for the support rod 6 to pass therethrough to cover the microwave absorber 1; and a fastening member is fastened to a tip threaded portion 12 of the support rod 6, thus attaching the microwave absorber 1 to the installation place. The gaps between adjacent ferrite plates 4 are filled with a magnetic sealing agent.
