Chemistry & Uses
Uses in perfumery :
Nootkatone can be used for fresh, citrusy or woody notes. Essential for a grapefruit note and to acidify rhubarb. Boosts top notes.
Year of discovery :
Data not available.
Natural availability :
Nootkatone can be isolated in its natural state from Grapefruit EO, which contains about 1 to 2%. Nevertheless, the Nootkatone used in perfumery is generally obtained synthetically.
Isomerism :
Nootkatone has three asymmetric carbons, one of which guides its enantiomer. Both enantiomers of the molecule have a similar smell. The racemic mixture is most often used, provided that the racemic mixture of Valencene is also used to synthesize it.
Synthesis precursor :
Nootkatone is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Nootkatone is synthesized by oxidation of a compound with a similar structure: Valencene, which can be isolated from Sweet Orange EO.
Stability :
Stable in perfumes and diverse functional bases
Other comments :
Nootkatone is the compound that gives Grapefruit EO its characteristic smell.
