Cineol is a natural organic compound that is a colorless liquid. It is a cyclic ether and a monoterpenoid.
Cineol is also known by a variety of synonyms: 1,8-cineol, 1,8-cineole, cajeputol, 1,8-epoxy-p-menthane, 1,8-oxido-p-menthane, eucalyptol, eucalyptole, 1,3,3-trimethyl-2-oxabicyclo[2.2.2]octane, cineol, cineole.
Cineol comprises up to 90 percent of the essential oil of some species of the generic product Eucalyptus oil, hence the common name of the compound. It is also found in camphor laurel, bay leaves, tea tree, sweet basil, wormwood, rosemary, common sage, sativa and other aromatic plant foliage. Eucalyptol with a purity from 99.6 to 99.8 percent can be obtained in large quantities by fractional distillation of eucalyptus oil.
Because of its pleasant spicy aroma and taste, eucalyptol is used in flavorings, fragrances, and cosmetics. Cineole-based eucalyptus oil is used as a flavouring at low levels (0.002%) in various products, including baked goods, confectionery, meat products and beverages. In a 1994 report released by five top companies, eucalyptol was listed as one of the 599 additives to. It is claimed that it is added to improve the flavor.
Eucalyptol is an ingredient in many brands of mouthwash and cough suppressant, as well as an inactive ingredient in body powder.
Eucalyptol is used as an insecticide and insect repellent.
In higher-than-normal doses, eucalyptol is hazardous via ingestion, skin contact, or inhalation. It can have acute health effects on behavior, respiratory tract, and nervous system. The acute oral LD50 is 2480 mg/kg (rat). It is classified as a reproductive toxin for females and a suspected reproductive toxin for males.
