Eucalyptol (also called cineole) is a monoterpenoid colorless liquid, and a bicyclic ether.[1] It has a fresh camphor-like odor and a spicy, cooling taste.[1] It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up about 70–90% of eucalyptus oil.[2][3] Eucalyptol forms crystalline adducts with hydrohalic acids, o-cresol, resorcinol, and phosphoric acid. Formation of these adducts is useful for purification.[4]
In 1870, F. S. Cloez identified and ascribed the name "eucalyptol" to the dominant portion of Eucalyptus globulus oil.[2]
