About
A fluoride salt permitted in oral care cosmetics up to 0.15% total fluoride, with general fluoride toxicity concerns.
Ammonium fluorosilicate (ammonium hexafluorosilicate) is used in some oral hygiene cosmetic formulations as a fluoride source. Under EU Cosmetics Regulation Annex III, it is permitted at up to 0.15% total fluoride concentration across all fluoride sources. Fluoride compounds at controlled concentrations are widely considered safe and effective for dental caries prevention.
