Science
Mechanism of Action
This complex functions as a 'flexible bond' technology, utilizing its dual-nature structure to bridge oil and water phases. It forms a breathable, non-stiff film on the surface that mimics the skin's Natural Moisturizing Factor (NMF) via its PCA moiety, effectively sealing in hydration while protecting the acid mantle.
Research
Clinical Evidence
High confidence0.3%
Key findings
- 01 Clinical testing demonstrated that at a 0.3% concentration, this molecule provides structural support and reduces breakage by 73% compared to traditional polymers, offering superior hold with flexible movement.

Dusting Analysis
Because this ingredient is highly effective at extremely low concentrations (under 0.5%), many brands may include it at negligible levels ('dusting') just for label claims. Moumoujus recognizes its efficacy starts at 0.1% for barrier support.
The Formula
Formulation
Stability
The addition of succinamide and PCA groups significantly improves the solubility of the chitosan backbone, allowing it to remain stable in water-based formulas above pH 4.5.
Synergies
- Hyaluronic Acid
- Squalane
- Ceramides
Conflicts
- High-concentration anionic surfactants
- Strong oxidizing agents
- Formulations with pH > 7.0
Safety
Safety Profile
While the specific complex is new to market, its constituent parts are well-established as safe. PCA should not be used in formulas that facilitate N-nitrosation.
