    Material Safety Data Sheet - Amorphous Silica Microspheres and Nanospheres

    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.

    • Appearance: Free flowing dry white powder
    • Particle Sizes: d50=2-4um or d50=4-8um
    • Spherical Particles: >99%
    • Density: ~1.9-2.2g/cc
    • Loss on Drying: 5% maximum
    • Oil Absorption: 140g ± 20g per 100g of sample
    • No Pathogens

    Coating: Optional Silicone Coating (Dimethylpolysiloxane)

    • Coating assures spheres to be floating on the distilled water for more than 1 hour
