Science
Mechanism of Action
This polycationic polymer utilizes electrostatic attraction to anchor itself to the naturally negative charge of the skin's stratum corneum. Once attached, it forms a semi-permeable polymeric matrix that significantly reduces transepidermal water loss (TEWL) and exerts antimicrobial effects by disrupting bacterial cell membranes through its positive ammonium groups.

Clinical Evidence
High confidence0.5%
Key findings
- 01 Demonstrated superior antioxidant capacity, specifically in scavenging hydroxyl and DPPH free radicals compared to standard chitosan.
- 02 Showed significant acceleration in wound closure and collagen synthesis via cytokine modulation.
- 03 Enhanced deep-layer skin penetration and follicular targeting of active ingredients by up to 9.6 times.
Transparency
Dusting Analysis
Because it is effective at very low concentrations (as low as 0.03% for biological signaling), many brands include it at 'label-claim' levels (below 0.01%) that fail to provide the structural film-forming or penetration-enhancing benefits seen in clinical data.
The Formula
Formulation
Stability
Highly resilient across a vast pH spectrum (1–13) and thermally stable up to 330°C. Unlike raw chitosan, this quaternized version remains soluble in non-acidic aqueous environments.
Synergies

Conflicts
- Anionic surfactants (SLS/SLES)
- Anionic thickeners (Carbomer, Xanthan Gum)
- Divalent cations (Magnesium Stearate, Calcium Carbonate)
Safety
Safety Profile
While not GRAS for systemic ingestion, it is widely utilized and considered safe for topical medical wound dressings and cosmetic applications.
