Science
Mechanism of Action
This ingredient functions via a 'triodetic' 3D architecture where positively charged chitosan moieties anchor to the negatively charged proteins on the skin and hair. The cellulose component provides internal structural reinforcement, resulting in a microscopic, non-rigid barrier that smooths the cuticle and protects the skin's surface from moisture loss.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Clinical evaluation at 0.3% demonstrated significant flexible hold and style retention in hair fibers, outperforming traditional synthetic polymers typically used at 10%.
- 02 Research on fungal-derived composites at 2.0% showed an 80% acceleration in wound-healing over 21 days by stimulating collagen synthesis and preventing bacterial growth.
Transparency
Dusting Analysis
Because this ingredient is effective at ultra-low concentrations (under 1.0%), it is less likely to be 'dusted' for marketing purposes; however, any inclusion below 0.1% may not provide the structural 3D network required for tangible barrier benefits.
The Formula
Formulation
Stability
Maintains peak stability in acidic to neutral environments; may precipitate or lose functionality if the formulation pH exceeds 6.5.
Synergies
- Humectants
- Non-ionic surfactants
- Cationic conditioning agents
Conflicts
- Anionic surfactants (SLS/SLES)
- Anionic thickeners (Carbomer, Xanthan Gum)
