Consumer Advice ​

Sodium aluminosilicate is an aluminium- and silicon-containing mineral used as an anticaking agent in table salt, milk powder and powdered seasonings. It is barely absorbed by the body and is permitted by the Codex Alimentarius and most national regulators within strict limits. Because it contains aluminium, consumers—especially children—should avoid excessive consumption of foods with aluminium-based additives over the long term.
