Eucalyptol
Eucalyptol
1,8-Cineole (Eucalyptol) is a natural bicyclic monoterpene ether isolated via steam distillation + vacuum rectification from Eucalyptus globulus/camphor leaves; it is the core component (70%–85%) of eucalyptus oil. With a strong cooling camphor + herbal + mint aroma, it is an essential raw material for pharmaceutical expectorants, cooling personal care, food flavoring, and natural insect repellents. Yunnan/Guangxi, China are the main production regions.

2. Source & Production Process
- Natural Source: Eucalyptus globulus, E. camphor etc(mainly Yunnan/Guangxi China, Australia, Spain, Portugal); leaf steam distillation yields eucalyptus oil (70%–85% cineole, plus pinene/limonene); China is the world’s largest natural cineole producer.
- Process (Natural physical isolation, no chemical modification):Eucalyptus leaves → Steam distillation → Crude eucalyptus oil → Vacuum precision rectification (175–178℃ cut) → Freeze refining → High-purity natural cineole
- Features: 100% botanical origin, pure aroma, strong cooling effect, intact bioactivity, FEMA/GRAS compliant, Kosher/Halal eligible.
