About

Magnesium Fluoride is a cosmetic ingredient. Exercise caution due to limited available safety data.

Magnesium fluoride is used as a fluoride source in some oral hygiene cosmetic formulations. Under EU Cosmetics Regulation Annex III, it is permitted at up to 0.15% total fluoride concentration. At these controlled concentrations, magnesium fluoride presents minimal toxicity concern. The fluoride component at controlled levels is considered beneficial for dental enamel remineralisation.

Known concerns

  • Restricted in EU (Annex III, max 0.15% F)
  • Low toxicity profile at permitted concentrations
  • Safe in oral care applications at approved levels
