Science
Mechanism of Action
Nepenthes mirabilis pitcher extract contains a potent cocktail of enzymes, including aspartic proteases (nepenthesins), β-1,3-Glucanase, and Class III and IV chitinases. These enzymes are adept at biodegrading complex polymeric molecules, decoupling proteins, degrading glucans, and hydrolyzing glycosidic bonds. Putative peroxidase 27 and Thaumatin-like proteins also contribute, suggesting an antioxidant capacity. The extract's naturally acidic pH, ranging precisely from 2.0 to 2.9, is crucial for its optimal hydrolyzing capabilities, facilitating the breakdown of dead skin cells and supporting enzymatic exfoliation.

Formulation
Stability
The pitcher fluid's enzymatic activity is stable and optimal within its native highly acidic pH range of 2.0-2.9. It maintains stability and activity at ambient temperatures, specifically between 15°C and 30°C.
Conflicts
- Ingredients sensitive to highly acidic pH environments (typically below 3.0)
- Protein-based ingredients, such as peptides or certain botanical extracts, due to the significant protease activity
- Certain polysaccharides, including specific gums or thickeners, which may be degraded by glucanase and chitinase enzymes
Safety
Safety Profile
No specific safety assessments by regulatory bodies such as CIR, SCCS, or FDA have been found for Nepenthes mirabilis pitcher extract in cosmetic applications. Its high acidity and enzymatic nature necessitate cautious evaluation for potential irritation or sensitization on the skin.
