Cineole

 

(also 1,8-cineole, eucalyptole), a terpene oxide having the structural formula

Cineole is a colorless liquid with an odor similar to camphor and ether. It is soluble in alcohol and ether but only slightly soluble in water. Cineole has a melting point of 1–1.5°C, a boiling point of 176–177°C, and a density of 0.923 g/cm3 at 20°C.

Cineole is obtained from many essential oils, especially eucalyptus oil; it is isolated from these oils by distilling them and then freezing out the portion that has a boiling point between 170°C and 180°C. Cineole is used in medicine and cosmetics as a component of antiseptics, expectorants, toothpastes, and elixirs.
