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.
The most prevalent is the standard cineole-based "oil of eucalyptus", a colourless mobile liquid (which yellows with age), having a penetrating, camphoraceous, woody-sweet scent. [2] China produces about 75% of the world output, but most of that is derived from the cineole fractions of camphor laurel rather than being true eucalyptus oil. [3]

Lister's work in turn inspired St. Louis-based doctor Joseph Lawrence to develop an alcohol-based formula for a surgical antiseptic which included eucalyptol, menthol, methyl salicylate, and thymol (its exact composition was a trade secret). Lawrence named his antiseptic "Listerine" in honor of Lister. [4]
