Description | Eucalyptol is an organic compound that is a colourless liquid. It is a cyclic ether and a monoterpene. Eucalyptol is a natural constituent of a number of aromatic plants and their essential oil fraction. Eucalyptol was given GRAS (Generally Recognized As Safe) status by the Flavor and Extract Manufacturer's Association FEMA, 1965 and is approved by the Food and Drug Administration for food use. 1,8-Dihydroxy-10-carboxy-p-menthane, 2-hydroxy-cineole, and 3-hydroxy-cineole are the main metabolites of eucalyptol. Toxicological data available on eucalyptol are rather limited. Following accidental exposure, death was reported in two cases after ingestion of 3.5-5 ML of essential eucalyptus oil, but a number of recoveries have also been described for much higher amounts of oil. In a 1994 report released by five top cigarette companies, eucalyptol was listed as one of the 599 additives to cigarettes. It is usually added to improve the flavour (PMID: 12048025 ). |
