Eucalyptol (1,8-Cineole)
B2B ingredient for professional formulation evaluation.
Eucalyptol (1,8-cineole) is a natural bicyclic monoterpene ether that is the principal constituent of eucalyptus oil (60-85% in Eucalyptus globulus). As a purified isolate, eucalyptol is a colorless liquid with a characteristic fresh, camphoraceous, eucalyptus-like odor. Fresure supplies high-purity eucalyptol (99% min) obtained through fractional distillation of eucalyptus oil under vacuum, with each batch verified by GC analysis. The isolate offers consistent, reproducible performance compared to whole eucalyptus oil, making it the preferred choice for pharmaceutical formulations, standardized flavor preparations, and applications requiring precisely defined active ingredient content.
