Zusammenfassung: | The present invention provides a cosmetic preparation which contains composite particles that are obtained by coating 1 part by mass of solid-core spherical borosilicate salt particles with 0.01 to 2 parts by mass of zinc oxide. The composite particles may be obtained by coating 1 part by mass of solid-core spherical borosilicate salt particles with 0.05 to 1.5 parts by mass of zinc oxide. The average particle diameter of the solid-core spherical borosilicate salt particles may be 0.1 to 20 [mu]m. |
