Uses
Uses in perfumery :
Farnesene is used to make fruity note greener, by bringing a quince note. It also brings a fruity and green note to floral accords.
Year of discovery :
Data not available.
Natural availability :
Many essential oils contain Farnesene isomers : Juniper Berry EO, Blue Chamomile EO, Lavender EO and Sambac Jasmine Absolute for example.
Isomerism :
Usually, Farnesene is used in perfumery as a mixture of isomers. Nevertheless, some plants contain precise isomers. Thus, Farnesene used in perfumery depends on the pant it is extracted from. For exemple, Ylang-Ylang III contains trans-alpha-Farnesene. Trans-beta-Farnesene is also to be distinguished, and can be found for example in Juniper Berry EO. Being a sesquiterpene, Farnesene is a constitutional isomer of Beta-Caryophyllene, Alpha-Cedrene and Valencene.
Synthesis precursor :
As any terpene, Farnesene can be used for the synthesis of many compounds, but it is not used for the synthesis of a compound used in perfumery.
Synthesis route :
Farnesene is rarely synthesized for its use in perfumery. It is usually extracted from plants as apple, perilla seed or ylang-ylang. A synthesis can nevertheless be considered, carrying out a Diels-Alder reaction, as for most terpenes.
