Nanoporous spherical silica particles with nanoparticles adhered to their surfaces and mica powder are generally used in cosmetic powders. To analyze the effect of surface-adhered nanoparticles and nanopores on bulk flowability, nanoparticles adhered to silica surfaces were removed by ultrasonic cleaning using water. To investigate the influence of the nanoporous structure of silica, nonporous silica...
In cosmetic powders, there are several kinds of powder materials widely used such as mica and silica on which nanoparticles are adhered on surface of the particle. However, it is not widely known that nanoparticles are adhered on the surface of these particles. In order to analyze the effect of these nanoparticles and silica particle nanopores on silica–mica surface interaction, the nanoparticles...
