The association Agir Pour l’Environnement announced on Facebook that 7 new brands have recently committed to remove titanium dioxide from their toothpastes. Their website https://dentifrice-infoconso.agirpourlenvironnement.org
has recently been updated to only 224 references that still contain titanium dioxide, down from 271 when it went live in March 2019. Titanium dioxide has thus disappeared from nearly fifty toothpastes in two years.
