Science
Mechanism of Action
This ingredient functions through electrostatic and lipophilic anchoring. Its cationic (positively charged) nature allows it to bond firmly to the negatively charged skin surface, while its C8 fatty acid chain integrates with the skin's lipid layers. This dual-action allows it to form a non-sticky, high-molecular-weight film that prevents transepidermal water loss (TEWL) while maintaining skin breathability.

Clinical Evidence
Medium confidence0.04%
Key findings
- 01 Demonstrated significant anchoring to skin-mimetic structures by increasing the phase transition temperature of phospholipid molecules.
- 02 Successfully reduced TEWL and maintained elevated hydration levels for over 120 minutes post-application.
Transparency
Dusting Analysis
Because it is typically supplied in a 1% or 2% solution, formulations often claim its presence while containing less than 0.01% of the actual active polymer. To achieve the 'veil' effect, concentrations equivalent to at least 1% of the raw material solution (0.01%-0.02% active) are required.
The Formula
Formulation
Stability
Highly stable across an exceptionally wide pH range due to its quaternized backbone. It is typically supplied as a liquid aqueous solution.
Synergies
- Phospholipids
- Ceramides
- Hyaluronic Acid
Conflicts
- Strongly anionic surfactants
- High levels of anionic thickeners like Carbomer or Xanthan Gum
Safety
Safety Profile
