| 摘要 |
In the present invention, a cosmetic having excellent transparency, spreadability, smoothness, skin compatibility, and safety is prepared using a synthetic talc that is flake-like particles containing 2:1-type laminar silicate crystals which have a substrate structure of an octahedron sheet sandwiched between two tetrahedron sheets. The volume-average particle diameter of the flake-like particles is 0.5 to 100 µm, the half-width of the peak present at 2Ө = 9.4˚<u>+</u> 1˚ is 0.3˚ or less in indeterminately-oriented-powder X-ray diffraction (XRD) measurement using CuKα rays, and the cosmetic is substantially Mg3Si2O5(OH)4-free. |
