■ Surface Treatments ■ Surface Treatments on Cosmetic Pigments and Substrates Since 1977, Miyoshi Kasei has offered the high quality and novel surface treatments on wide range of powders. Now the basic powder ingredients that can be treated count over 300, ranging from typical fillers such as talc, mica, sericite, spherical powders, iron oxides, titanium dioxide, and organic colorants to more sophisticated inorganic particulate sunscreens such as microfine titanium dioxide and microfine zinc oxides. Not only do we treat many of the powders available from manufacturers throughout the world but we also produce special grade powders ourselves. If you have a powder that needs to be improved in texture, or hydrophobic properties, we will be more than happy to surface treat them! For complete product listing, please see "Pigments & Substrates."
