POWDER FOR COSMETICS AND COSMETICS COMPOUNDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain powder for cosmetics by easily taking out a pearl layer of a pearl oyster by utilizing the state of the calcium carbonate of a pearl oyster shell.

SOLUTION: The powder for the cosmetics with the thin-sliced calcium carbonate as a main component is characterized in that the pearl oyster shell is crashed after being immersed in an alkaline solution, and sorted at 200 to 500 meshes. Furthermore, an effect is increased by heat-treating spherical powder whose average particle diameter is 0.05 to 0.5μ on the surface of the powder, and effectiveness such as the light scattering property and transparency is enhanced.
