Potassium aluminium silicate is an artificial food additive used as an anticaking agent (INS 555).[1] Potassium aluminosilicates also occur naturally, as the mineral orthoclase (KAlSi3O8) and as other aluminosilicate minerals.

Potassium aluminium silicate is permitted as an anticaking agent for a limited range of food products[note 1] in the European Union.[2][3][4][5] It is not permitted in Australia and New Zealand[6] or in Canada,[7] and there is no record of its use in the United States.
