Polydisperse silica microspheres are porous ceramic spherical beads. Uncoated silica spheres exhibit excellent dispersibility, good oil absorbancy, and good fluidity. They are used in emulsion and make-up products, as anticaking agents and additive and perfume carriers. Optional silicone coating makes the spheres very hydrophobic, transparent, easy to disperse, resistant to acids and alkalis, resistant to UV and moisture.
