What is colloidal silicon dioxide?
Colloidal silica is a gaseous silica prepared by hydrolysis of silica compounds. It is a kind of fine silicon that can be uniformly dispersed. It is insoluble in water. Silicon is a natural element in the periodic table. It is nontoxic and is often used in industry. It is also the second most common element in the earth's crust, after oxygen.
What is colloidal silicon dioxide used for?
Food usually contains colloidal silica. This is because it can act as a free-flowing agent. It is found in salt, seasoning salts and sodium bicarbonate (baking soda). It is also found in spices, meat pickling powder and many other foods that require anti-caking agents.
Because colloidal silica is inert and insoluble in water, it is commonly used as a coating for pills and dietary supplements. The trade name of medical grade colloidal silica is "Aerosil".
Colloidal silica can also be used as a thickener in industrial environments, such as paints, dyes, shampoos and some cosmetics. When used as an industrial thickener, its trade name is "Cab-o-Sil".
Is colloidal silicon dioxide toxic?
FDA believes that colloidal silica is usually safe, and most studies have shown that the silica we ingest through foods and supplements is safe.
In fact, it has been found that it does not accumulate in the body. According to the World Health Organization, excess silicon dioxide is excreted through the kidneys. In addition, the researchers found no association or association between silicon dioxide added to food and an increased risk of organ damage, disease or death.
Is silicon dioxide good for your health?
Silicon dioxide naturally exists in the earth and in our bodies. There is no evidence that it is dangerous to use it as a food additive. But inhaling silica can cause health problems.
There are many forms of silica. The type of silicon dioxide added to foods, supplements and medicines is different from crystalline silicon dioxide. Inhaling silica dust is unsafe. Continuous exposure to silica dust in the air can lead to silicosis, a lung disease. In essence, silica has a crystal structure. Inhaling it will introduce these crystals into your lungs in the form of nanoparticles. These nanocrystals create small incisions in your lung tissue. Over time, this forms scar tissue in the lungs, making it more difficult to breathe.
