发明名称 MAGNETIC POWDER FOR COSMETIC AGENT
摘要 <p>A magnetic powder for cosmetic agents, configured so as to be capable of being adsorbed and removed by magnetic force from a cosmetic agent applied to the face. The magnetic powder for cosmetic agents has a magnetite content of at least 80% by mass, the remaining content being wüstite, hematite, and unavoidable impurities. The volume average particle diameter found using the particle distribution obtained by the laser diffraction scattering method is 50-75 µm. The magnetic powder contains no more than 15% by mass particles having a particle diameter of less than 37 µm and contains no more than 5% by mass particles having a particle diameter of at least 105 µm.</p>
