Utilisation

Uses

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

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.

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.

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.

Annexe I :

Some regulated synthetic ingredients are found in nature and in certain proportions in natural ingredients. This presence in nature has to be taken into account when calculating limits of use recommended by the IFRA. In case you do not know these concentrations, you can use the ones estimated by the IFRA.
