E554Anti-caking agentModerate concern
Sodium Aluminium Silicate
In plain words
The short version
A common US salt anti-cake — restricted in the EU since 2014 because of aluminium concerns.
Why we flag it amber
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI of 0–1 mg/kg body weight (combined aluminium, EFSA 2008). The crystalline aluminosilicate is largely non-absorbed in the gut; the absorbable aluminium fraction (varying by particle size and pH) is the regulatory concern. EU restricted its use in 2014 — US permission continues.
