Less Than 2% Silicon Dioxide Added As An Anticaking Agent

Silicon dioxide is a form of silica, which is a common compound found in nature, like in sand. It is manufactured for use in food by reacting silicon tetrachloride with oxygen and water. It appears as a fine white powder.

Manufacturers add silicon dioxide to powdered or granulated foods to prevent clumping and ensure a free-flowing product. It acts as an anticaking agent, absorbing moisture and keeping particles separate. It is commonly found in spices, salt, powdered drink mixes, and baking powders.

Silicon dioxide is Generally Recognized As Safe (GRAS) by the FDA for use as an anticaking agent. It is indigestible and passes through the body unchanged. JECFA and EFSA have evaluated silicon dioxide and established acceptable daily intakes. It is not known to cause adverse health effects at the low levels typically consumed.
