Synthetic amorphous sodium aluminosilicate is widely used as a food additive, E 554.

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.

[3] Sodium aluminosilicate is used as molecular sieve in medicinal containers to keep contents dry.

[citation needed] Naturally occurring minerals that are sometimes given the chemical name sodium aluminosilicate include albite (NaAlSi3O8, an end-member of the plagioclase series) and jadeite (NaAlSi2O6).
