Sodium aluminosilicates, sometimes called sodium silicoaluminates (especially in the United States), are a large class of compounds of general formula Na(2x)Al(2y)SizO(x+3y+2z)·mH2O, also written as xNa2O·yAl2O3·zSiO2·mH2O. They occur widely in nature as feldspars and other aluminosilicate minerals, and are also produced artificially on a large scale as zeolites, especially for use in laundry powders.[1]
Amorphous sodium aluminosilicate is manufactured for use as an anticaking agent in food (INS 554).[2] It is "generally recognized as safe" (GRAS) at levels of less than 2% in the United States,[3] and is also approved for use in Australia and New Zealand,[4] Canada[5] and (in a limited range of products) in the European Union.[6][7][8][9]
