Chemistry, Properties & Perfumer Guide
The Chemistry
Peppermint oil terpenes are primarily composed of monoterpenes including menthol, menthone, and limonene. These compounds are extracted through steam distillation of Mentha piperita leaves. The characteristic cooling sensation comes from menthol’s ability to activate TRPM8 receptors in the skin. Different cultivars and growing conditions affect the exact terpene profile, with European peppermint typically containing higher menthol content than American varieties.
