What it is
Silicon dioxide is a synthetic, non-toxic, odorless, tasteless, white powder. It is a form of silica, which is a naturally occurring mineral. It is manufactured by combining silicon with oxygen.
Why it's used
Manufacturers add silicon dioxide to powdered foods to prevent clumping and ensure a free-flowing texture. It acts as an anti-caking agent, absorbing moisture and keeping particles separate. It is commonly found in spice blends, powdered drink mixes, and salt.
Health notes
Silicon dioxide is generally recognized as safe (GRAS) by the FDA for use as an anti-caking agent. It is not absorbed by the body and is excreted unchanged. International bodies like JECFA have evaluated it and found it safe for consumption. No significant health concerns have been associated with its use at typical dietary levels.
Allergen info
Silicon dioxide is not derived from any of the nine FDA major allergens. It does not contain gluten.
