Sodium aluminium phosphate is a food additive (INS 541).[1] It comes in two forms, acidic (INS 541(i))[2] and basic (INS 541(ii)).[3] Both forms may be used as emulsifier and acidity regulators,[1] while the acid form is also a raising agent.[2]

Sodium aluminium phosphate is "generally recognized as safe" (GRAS) for use in table salt in the United States,[4] and is also permitted for use in Canada.[5] However, it is not permitted for use in Australia and New Zealand.[6] In the European Union, only the acid form may be used, and then only as a raising agent in scones and sponges.[7][8]
