Dusting Analysis
As this ingredient is mainly utilized in oral care and not commonly formulated into leave-on skincare, the concern of 'dusting' is generally not applicable.
The Formula
Formulation
Stability
This compound is prone to hydrolysis in acidic conditions or prolonged water exposure, breaking down into fluoride and phosphate. It shows improved stability in glycerol-water mixtures.
Conflicts
- Calcium salts (may precipitate as calcium fluoride)
- Strong acids
- Metal ions (can form complexes affecting appearance)
Safety
Safety Profile
The maximum concentration of 0.15% is calculated as total Fluorine (F) and is regulated for oral care. This ingredient is not typically used in leave-on skincare products.
