Sodium Aluminum Silicate

Sodium aluminum silicate is a synthetic inorganic compound made from sodium, aluminum, silicon, and oxygen. It is produced by reacting solutions of sodium silicate and aluminum sulfate under controlled conditions. The resulting powder is then dried and processed.

Manufacturers use sodium aluminum silicate as an anti-caking agent. It helps prevent powdered foods from clumping together, ensuring a free-flowing texture. It is commonly found in powdered drink mixes, spices, and baking mixes.

In the United States, sodium aluminum silicate is generally recognized as safe (GRAS) by the FDA when used as intended. It is not known to cause adverse health effects at the levels typically consumed. International bodies like JECFA have evaluated its safety, and EFSA has also assessed its use as a food additive. Evidence does not indicate significant health concerns at typical dietary intake levels.
