Science
Mechanism of Action
As a cationic surfactant, it utilizes a positively charged amine group to ensure superior spreading and adhesion to oral surfaces. It reacts with calcium in the teeth to precipitate a calcium fluoride (CaF2) depot, which acts as a sacrificial layer against acid erosion while inhibiting the bacterial enzyme enolase to disrupt plaque metabolism.
Research
Clinical Evidence
High confidence0.15%
Key findings
- 01 Demonstrated significant fluoride uptake in demineralized dentine and enamel, resulting in reduced caries incidence (UCL Discovery, 2005).
- 02 Proven effective at 0.2% concentration for the immediate and long-term reduction of cervical dentin hypersensitivity over a 6-month period (SciELO, 2010).
Transparency
Dusting Analysis
Due to strict EU regulatory limits (0.15% as Fluorine), this ingredient is typically used at its maximum functional concentration. Formulations containing less than 0.1% may fail to provide the necessary fluoride 'depot' required for remineralization.
The Formula
Formulation
Stability
Optimal stability and fluoride deposition are achieved in slightly acidic environments; the compound is frost-sensitive and must be stored above 0°C.
Synergies
- Non-ionic surfactants
- Slightly acidic buffers
Conflicts
- Anionic surfactants
- Sodium lauryl sulfate (SLS)
- Calcium-containing abrasives
Safety
Safety Profile
Regulated under EU Cosmetics Regulation Annex III/1, 36. Maximum concentration is 0.15% calculated as Fluorine. Requires specific cautionary labeling for children under 6 years to prevent ingestion.

Verdict
An essential active for targeted enamel remineralization and dentin desensitization, provided it is formulated within a specific acidic pH range and away from anionic surfactants.
