Aluminium silicate is a food additive used as an anticaking agent (INS 555).[1] It is the standardised name given to food-grade kaolinite, also known as kaolin.[2] The same product is used as a medication for certain gastrointestinal disorders, notably constipation.[3]

Aluminium silicate is permitted as an anticaking agent for a limited range of food products[note 1] in the European Union.[4][5][6][7] It is also permitted in Australia and New Zealand[8] but not in Canada,[9] and there is no record of its use in the United States.
