Science
Mechanism of Action
This cationic surfactant carries a potent positive charge that naturally gravitates toward the negatively charged keratin proteins found in skin and hair. Upon contact, it forms a uniform, hydrophobic film that seals the stratum corneum, effectively neutralizing static electricity while preventing trans-epidermal moisture loss.

Key findings
- 01 Laboratory analysis indicates that a 1.0%-3.0% concentration delivers a 6x increase in surface smoothness and reduces frizz by 75%.
- 02 Performance data shows a 2x improvement in shine that remains resilient through at least three consecutive cleansing cycles.
Transparency
Dusting Analysis
While often used in hair care, its role as a skin-feel enhancer in body care requires at least 0.5% to provide perceptible smoothing benefits; inclusions below 0.2% are typically for stabilization rather than performance.
The Formula
Formulation
Stability
Peak performance and structural integrity are observed in slightly acidic environments between pH 4.0 and 5.5. It utilizes charge repulsion to prevent droplet coalescence in complex emulsions.
Synergies
- Non-ionic surfactants
- Silicone alternatives
- Acidic active ingredients
Conflicts
- Anionic surfactants (SLS/SLES)
- Anionic thickeners (Carbomer)
- Strong oxidizing agents
