Calcium aluminium silicate is an artificial food additive used as an anticaking agent (INS 556).[1][2] Calcium aluminosilicates also occur naturally, as the mineral anorthite (CaAl2Si2O8) and as other aluminosilicate minerals.
Calcium aluminium silicate for food use contains some sodium (0.5–4% by weight, expressed as Na2O) and relatively little aluminium (3–5% by weight, expressed as Al2O3):[2] the approximate formula is NaCa6AlSi8O24·xH2O.
Calcium aluminium silicate is permitted as an anticaking agent for a limited range of food products[note 1] in the European Union.[3][4][5][6] It is also permitted in Australia and New Zealand[7] and in Canada.[8] It is "generally recognized as safe" (GRAS) for use in table salt in the United States,[9] where it may also be used in vanilla powder at levels of less than 2%.[10]
