Consumer Advice ​

Potassium aluminium silicate is a mineral anticaking agent containing aluminium, potassium and silicon, used mainly to keep powdered foods free-flowing. It is minimally absorbed by the body and considered safe within approved limits. Because it contains aluminium, its permitted uses are tightly controlled in many countries, and consumers may choose to limit their intake of aluminium-containing processed foods.
