Natural Isolate
Natural eucalyptol, fractionally distilled in Australia
1,8-Cineole (eucalyptol) is the fresh, cooling, camphoraceous molecule at the heart of eucalyptus oil. Oleinza Naturals supplies it as a high-purity natural isolate: eucalyptus-origin feedstock, recovered and purified by multi-stage fractional distillation and short-path distillation at our Coburg North, Victoria facility.
No synthesis, no chemical modification, physical separation only. Each batch is analysed by GC-FID and GC-MS before release and ships with a Certificate of Analysis.
