There are several cedarwood oils with different physical and chemical properties. They are often referred to in the literatnre simply as cedarwood oil. The most common ones, cedarwood oil Virginia, cedarwood oil Texas, and cedarwood oil Atlas, are derived from J. virginiana, J. mexicana, and C. atlantica, respectively. Others such as cedarwood oil Himalaya, cedarwood oil East Africa, and cedarwood oil Japanese are obtained from other conifers (arctander). Juniperus ashei Buchh. is also used as a source of cedarwood oil other species (e.g., J. erythrocarpa Cory and J. scopulorum Sarg.) containing high oil content are potential sources. ... 

Cedarwood oil Texas is prepared by steam distillation of the wood (shavings, etc.) of J. mexicana, which is a small tree up to about 6 m high growing in mountains of southwestern United States, Mexico, and Central America. The oil is produced in Texas it has an odor similar to that of Virginia cedarwood oil. 

Cedarwood oil Texas contains similar major constitnents as cedarwood oil Virginia (arctander karrer). ... 

Ced rwood. Many varieties of cedarwood oil are obtained from different parts of the world. They are produced mainly by steam distillation of chipped heartwood, but some are also produced by solvent extraction. The oils, which vary significantly ia chemical composition, are used ia perfumes as such, but the main uses are as distillation fractions and chemical derivatives. For the latter purposes the most used oils, which are similar ia composition, are from Texas ia the United States (Juniperus mexicand) and from China Cupressusfunebris). The principal constituents of these oils are cedrene [11028-42-5] (4), thujopsene [470-40-6] (5), and cedrol [77-53-2] (6). The first two of these are obtained together by distillation and used mostiy ia the form of acetylated derivatives. Cedrol is used as such and, to a greater extent, as its acetate ester. 

Chinese cedarwood oil is similar in composition to Texas cedarwood oil (see below). Chinese cedarwood oil is obtained by steam distillation of Chamaecyparis funebris (Endl.) France (Cupressusfunebris Endl., Cupressaceae), which is a weeping cypress, indigenous to China. Commercial Chinese cedarwood oil is a colorless to slightly yellow oil with an odor more smoke-like than the American oils.

The price of Cedarwood oil from Texas in 1995 was 7.70/kg and the price of the oil from Virginia was 15.18/kg (69). Distillation of the oil gives two main fractions, the cedrene or hydrocarbon fraction, and the alcohol fraction consisting of impure cedrol, which when purified by crystallization can be used direcdy in perfumery. Cedrenol is a product comprising a mixture of cedrol and its isomers widdrol and some ketone components. 

A) American cedarwood oils Virginia C. is a somewhat viscous, yellowish oil with a soft, woody, sweet and balsamy odor of pencils. Texas C. is a viscous, reddish to brownish oil with an odor similar to that of the Virginia oil. Part of the content of cedrol often crystallizes from the oil. 

All three types of cedarwood oils (Virginia, Texas, and Atlas) are primarily used as fragrance components or fixatives in cosmetic and household products, particularly soaps and detergents others include creams, lotions, and perfumes. The maximum use level reported is 0.8% for all three in perfumes. ...
