Health notes
Titanium dioxide is authorised as a food additive in Great Britain. EFSA re-evaluated titanium dioxide (E171) in 2021 and concluded that it could no longer be considered safe as a food additive, citing concerns about genotoxicity. Following this, the European Commission amended Regulation (EC) No 1333/2008, and E171 is no longer authorised for use as a food additive in the EU and Great Britain. JECFA has also evaluated titanium dioxide.
