Diatomaceous earth, a mined product, has been used in food and cosmetics for centuries.
Silicon Dioxide Powder consists of the silica shells of microscopic diatoms; in a less processed form it was sold as "tooth powder".
Manufactured or mined hydrated silica is used as the hard abrasive in toothpaste.
Silicon Dioxide Powder exist as white, fluffy powders that are produced through a wet process, yielding silica or silica gel, or a thermal route, yielding pyrogenic (fumed) silica.
In powdered foods, the silica clings to the particles of the foods and prevents them from clumping.
This allows powdery products to remain free-flowing, and other products easy to separate.
Silicon Dioxide Powder also functions as a defoaming agent, carrier, conditioning agent, chillproofing agent in malt beverages (like beer) and filter aid.
Safety Profile Of Silicon Dioxide Powder:
Silicon Dioxide Powder in normal doses, such as the small amounts that manufacturers put in food products to prevent caking.
The pure unaltered form is considered a nuisance dust.
Some deposits contain small amounts of crystahne quartz and are therefore fibrogenic.
When diatomaceous earth is calcined (with or without fluxing agents) some sdica is converted to cristobalite and is therefore fibrogenic.
Tridymite has never been detected in calcined batomaceous earth.
Silicon Dioxide Powder ingested orally is essentially nontoxic, with an LD50 of 5000 mg/kg (5 g/kg).
When fine silica particles are inhaled in large enough quantities (such as through occupational exposure), it increases the risk of systemic autoimmune diseases such as lupus and rheumatoid arthritis compared to expected rates in the general population.
Diatomaceous earth is used as a filtering agent and as a filler in construction materials, pesticides, paints, and varnishes.
The calcined version (which has been heat treated) is the most dangerous and contains crystallized silica, and should be handled as silica.
Side effects and risks of Silicon Dioxide Powder:
Some researchers have called for further investigation into the types of silica that find their way into food products.
These include nanoparticles, which are silica particles that are much smaller than most of the particles that occur in nature.
The concern is that these tiny particles could reach different areas of the body and even get into the cells themselves.
Many food additives tend to raise concerns from people who want to be aware of what they are eating, and Silicon Dioxide Powder is no different.
Inhaling finely divided crystalline silica can lead to severe inflammation of the lung tissue, silicosis, bronchitis, lung cancer, and systemic autoimmune diseases, such as lupus and rheumatoid arthritis.
Inhalation of amorphous Silicon Dioxide Powder, in high doses, leads to non-permanent short-term inflammation, where all effects heal.
While the name may seem unfamiliar, Silicon Dioxide Powder is a natural compound. Many studies suggest that there is no cause for concern when people are consuming Silicon
