Uses
Other comments :
The smell of Farnesol becomes stronger when the molecule is evaporating, surely due to oxydation.
Farnesol is part of the sesquiterpene molecule category. This means that this molecule has fifteen carbon atoms, that is three isoprene units. Terpenes (monoterpenes, diterpenes, sesquiterpenes...) were discovered thanks to the Diels-Alder reaction, involving a diene and a dienophile, abling to modelize terpenes and to obtain a great variety of them.
Stability :
Terpenes may polymerize under strong oxydation.
Uses in perfumery :
Farnesol is used for lily of the valley notes, to bring a fruity nuance. It is also used as a fixative.
Year of discovery :
Discovered in 1913
Isomerism :
Farnesol has four stereoisomers, due to the presence of two double bonds. Thus, these two bonds can have either a cis (Z) or trans (E) configuration. The four stereoisomer couples of Farnesol are : (Z,Z), (E,E), (Z,E) and (E,Z). In perfumery, a mixture of isomers is used most of the time, because no real olfactive difference exist between the isomers.
Synthesis precursor :
Farnesol is not used for the synthesis of another compound of olfactive interest.
Natural availability :
Farnesol can be extracted from Ambrette Seeds Absolute, because it is found there in its (Z,E) conformation. It is also found in Petitgrain Bigarade EO and Orange Blossom Absolute, from which it can be extracted.
Synthesis route :
Synthetic Farnesol can be obtained by isomerization of Nerolidol. This synthesis is mostly replacing the natural extraction of Farnesol, as it was formerly usual.
