Sodium Benzoate And Silicon Dioxide

Silicon dioxide is a form of silica, which is a common compound found in nature as sand and quartz. It is manufactured for food use by processes like flame-syring or precipitation. Sodium benzoate is a salt of benzoic acid, a synthetic preservative.

Silicon dioxide is used as an anti-caking agent to prevent powders from clumping. Sodium benzoate is a preservative that stops the growth of mold, yeast, and bacteria. They are often found in powdered drink mixes, spices, and baked goods.

Silicon dioxide is Generally Recognized As Safe (GRAS) by the FDA for use as an anti-caking agent. Sodium benzoate is also FDA approved as a food additive and preservative. Both have been evaluated by JECFA and EFSA. Some studies have explored potential links between sodium benzoate and hyperactivity in children, but evidence is mixed and FDA has not issued specific guidance on this.
