Alpha-Cedrene is used primarily to create leather notes or as a substitute for Virginia cedarwood essential oil (Cedarwood Virginia EO) because of its essentially equivalent scent. It is one of the main components of various cedarwood essential oils, including Cedarwood Virginia EO, Cedarwood Texas EO, and Cedarwood Chinese EO, and it is found in small amounts in verbena essential oil (Verbena EO).
Alpha-Cedrene was first isolated in 1841 by the scientist Walter from the plant Juniperus virginiana. Its chemical synthesis was first achieved in 1953 by Stork and Breslow, who synthesized dl-cedrol and dl-Alpha-Cedrene, and two years later they accomplished the full synthesis of cedrol and Alpha-Cedrene.
From a chemical standpoint, Alpha-Cedrene belongs to the category of sesquiterpenes, meaning it has 15 carbon atoms bonded to 24 hydrogen atoms. Its molecular structure is characterized as a tricyclic structure, which affects its aromatic properties.
Historical discovery: Alpha-Cedrene has a long history in the world of fragrances, having been isolated for the first time more than 180 years ago (1841) by the scientist Walter, at a time when organic chemistry was still in its early stages.
Scientific achievement: It took more than 100 years after its isolation for scientists to synthesize it in the laboratory. Stork and Breslow achieved the synthesis of Alpha-Cedrene between 1953 and 1955, paving new paths in the production of aromatic ingredients.
The tricyclic structure of Alpha-Cedrene is crucial for its characteristic scent. This complex molecular architecture gives it the specific aromatic properties that resemble cedarwood, making it a valuable ingredient in creating fragrances with woody and leather notes.
The IFRA Standards form an industry self-regulatory system. They may prohibit or restrict the use of particular fragrance ingredients, or set specifications, according to end use. The status below reflects the IFRA data recorded for this ingredient. It is not a product certification and does not replace applicable law or assessment of the finished product.
IFRA categories group end uses by the type and level of exposure. A restriction or maximum concentration applies only to the stated category and does not automatically apply to another use. Check the related IFRA document for the applicable Standard version and its full conditions.
