Science
Mechanism of Action
This ingredient utilizes a cationic (positively charged) quaternary ammonium group to intelligently seek out and bind to negatively charged damaged sites on the skin and hair. By mimicking the structure of 18-Methyleicosanoic acid (18-MEA)—the primary lipid found in the skin's surface F-layer—it forms a seamless, protective film that reinforces barrier function and provides a smooth, conditioned texture.

Key findings
- 01 Manufacturer testing (Seiwa Kasei) validates its efficacy in mimicking the 18-MEA lipid layer to repair damaged surfaces when used between 1-5%.
- 02 Safety and compatibility studies cited by the CIR (2016) demonstrated that a 3% concentration in topical applications significantly supports skin barrier integrity without causing adverse reactions.

Dusting Analysis
Because it is a specialized complex, it is often included at 'claim' levels below 0.5% in mass-market products. At Moumoujus, we look for concentrations of at least 1-3% to ensure the biomimetic film-forming properties are physiologically active.
The Formula
Formulation
Stability
Highly stable in both oil-in-water and water-in-oil emulsions within an acidic to neutral pH range. It is thermo-sensitive; formulation must occur below high temperature thresholds to prevent degradation of the protein structure.
Synergies
- Ceramides
- Glycerin
- Fatty acids
Conflicts
- High concentrations of anionic surfactants
- Strong oxidizing agents
Safety
Safety Profile
While the specific succinoyl complex is relatively new, its parent component, Hydrolyzed Keratin, is established as safe for leave-on use up to 5%.
