摘要:
A cosmetic of the present invention contains glass flakes. The glass flakes have a composition including at least 52 mass% of silicon dioxide and 5 mass% or less of alkali metal oxides. The glass flakes have an average thickness of 0.1 to 1.0 µm, an average particle diameter of 1 to 100 µm, and an average aspect ratio of 10 or greater. The average aspect ratio is obtained by dividing the average particle diameter by the average thickness. The particle diameter distribution index of the glass flakes is 5.0 or less. The particle diameter distribution index is obtained by dividing D90 by D10, where in the particle size distribution of the glass flakes, D10 is a particle diameter at which the cumulative mass distribution of particle diameters reaches 10% when counted from the smaller side, and D90 is a particle diameter at which the cumulative mass distribution of particle diameters reaches 90% when counted from the smaller side.
