About N,N',N'-Tris(polyoxyethylene)-N-hexadecylpropylenediamine dihydrofluoride
A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Detailed Analysis
This ingredient is a polyethoxylated amine with a hexadecyl (C16) alkyl chain, complexed with dihydrofluoride (F·HF), used primarily in oral care cosmetic formulations as an anticaries agent. The EU restriction (II/21) limits total fluoride concentration to 0.15% when mixed with other permitted fluorine compounds, a threshold set by the SCCS for safety in cosmetic oral care products. The fluoride is present as a buffered HF species rather than free fluoride ion, which affects its bioavailability. Compliance with the fluoride ceiling is mandatory, and products containing this ingredient require accurate fluoride accounting across all sources.
Skin Benefits
- ✓ Fluoride contributes to caries prevention in oral care products
- ✓ Surfactant properties aid in cleaning and delivery
Known Concerns
- ⚠ EU Annex II/21: Total F must not exceed 0.15% when combined with other fluorine compounds
- ⚠ Risk of fluorosis in children at excessive concentrations
- ⚠ Requires careful formulation to ensure controlled fluoride release
Safety Score
Moderate
Based on EU regulatory data, published safety research, and ingredient function analysis.
