What it is

Silicon dioxide is a naturally occurring compound made of silicon and oxygen. It is found in sand and quartz. It is manufactured for food use by reacting silicon tetrachloride with oxygen.

Why it's used

Silicon dioxide is used as an anti-caking agent, meaning it helps prevent powdered foods from clumping together. It can also act as a flow agent, allowing powders to be dispensed evenly. It is found in dry mixes, spices, and powdered supplements.

Health notes

Silicon dioxide is generally recognized as safe (GRAS) by the FDA for use in food. International bodies like JECFA have evaluated it and established an acceptable daily intake. It is not known to cause adverse health effects at typical dietary levels.
