Our Silicon Dioxide is a fluffy white coloured powder which has no odour. This product’s certificate of analysis is available on request.

It is an additive commonly used by the food, supplement and pharmaceutical industries to prevent ingredients from sticking together. For example, manufacturers add Silicon Dioxide to salt and many spices to keep those dry substances from clumping.

Its main uses are in tablet-making, including as an anti-caking agent, adsorbent, disintegrant or glidant to allow powder to flow freely when tablets are processed. These compounds appear to be biologically inert, which means it will not interfere with any active ingredients in supplements or drugs.

Silicon Dioxide has an extremely high melting point so it is useful in electronics where high heat is produced. The mineral is essential for manufacturing fibre optic cables, semi-conductors, and insulation for wires. Silicon Dioxide is generally recognized as safe by the FDA.

  1. Quick Receipt Review by Nick

    Product took 2 days from order to delivery.

    A little disappointing that the product arrived in an unprinted, tie-wrapped back when I was expecting a printed doy pouch or similar, as in the photos.

    Clearly 25kg bulk crudely decanted with price not reflective. (Posted on 14/07/2016)

  2. Quality Flowing Agent Review by Mark

    This has helped with a few of our applications now and has worked well when needed. (Posted on 06/07/2016)
