text: This substance is produced with a wide range of compositions and has many different applications. It is encountered as an additive E 554 in food where it acts as an anticaking (free flow) agent. As it is manufactured with a range of compositions it is not strictly a chemical compound with a fixed stoichiometry. One supplier quotes a typical analysis for one of their products as 14SiO·AlO·NaO·3HO,(NaAlSiO·3HO).
  The US FDA has as of April 1, 2012 approved sodium aluminosilicate (sodium silicoaluminate) for direct contact with consumable items under 21 CFR 182.2727. Sodium aluminosilicate is used as molecular sieve in medicinal containers to keep contents dry.
  Sodium aluminosilicate may also be listed as:
  * aluminium sodium salt
  * sodium silicoaluminate
  * aluminosilicic acid, sodium salt
  * sodium aluminium silicate
  * aluminum sodium silicate
  * sodium silico aluminate
  * sasil
