Science
Mechanism of Action
This ingredient functions as an agonist for the Transient Receptor Potential Melastatin 8 (TRPM8) ion channel. By stimulating these cold-sensitive sensory neurons, it triggers a perceived cooling sensation on the skin's surface without inducing an actual drop in tissue temperature or causing the irritation sometimes associated with high concentrations of menthol.

Key findings
- 01 Evaluation of bioactive TRPM8 modulation for non-thermal skin cooling (US Patent 2017/0087199 A1)
- 02 IFRA-derived olfactory stability and fragrance profile assessment (The Good Scents Company)
Transparency
Dusting Analysis
In many commercial formulas, this ingredient is included at negligible concentrations (under 0.1%) simply to mask base odors. To achieve its functional bioactive cooling effect, a concentration of at least 1.0% is required.
The Formula
Formulation
Stability
Exhibits maximum stability in acidic environments; highly susceptible to hydrolysis in alkaline conditions or high-water-content formulations which can degrade the ester into benzyl alcohol.
Synergies
- Acidic stabilizers
- Oil-based delivery systems
- Other TRPM8 modulators
Conflicts
- Strong bases
- Strong oxidizing agents
- High-alkalinity environments
- Aqueous formulas intended for long-term shelf storage
Safety
Safety Profile
Recognized as GRAS (Generally Recognized as Safe) by FEMA (#2136) and FDA-approved for food flavoring. While concentrated forms are irritants, it is considered safe and non-sensitizing at the levels typically utilized in cosmetic applications.
