Science
Mechanism of Action
Its predominant role in topical products is to impart sensory characteristics through fragrance. Despite its well-documented activity as a plant phytohormone, influencing botanical defense and development, no specific mechanism of action demonstrating benefits like anti-aging or hydration for human skin has been identified.

The Formula
Formulation
Stability
This ingredient exhibits robust solubility in oils and various organic solvents, including ethanol, DMSO, and dimethyl formamide. Its solubility in water is limited, measured at approximately 0.34 to 1.01 grams per liter at 25°C. Aqueous solutions are not recommended for extended storage, typically beyond one day, due to potential stability concerns.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded this ingredient is safe under current usage conditions. The Research Institute for Fragrance Materials (RIFM) similarly supports its safe incorporation into everyday products. While the PubChem GHS classification indicates no hazard for 81% of reports, a smaller fraction (19%) identifies potential harm if swallowed or serious eye irritation. Notably, its synonym, methyl jasmonate, holds an FDA exemption from food tolerance requirements due to its low toxicity profile.
