Chemistry & Uses
Uses in perfumery :
Trans-2-Hexenol is used in green notes and unripe fruit accords. Also used in stem notes for floral accords. Makes a honeysuckle more vegetal and fresh. Allows you to nuance floral notes. Gives a fresh appearance to jasmine, freesia or peony.
Year of discovery :
Data not available.
Natural availability :
Trans-2-Hexenol is found naturally in Roman Chamomile EO and Violet Leaf Absolute, and can therefore be naturally extracted, although synthetic trans-2-Hexenol is more often used.
Isomerism :
Trans-2-Hexenol has a more fruity, apple-like smell than cis-3-Hexenol, which is purely green. This is why it is more often used in fruity accords than cis-3-Hexenol, that is used in flowery accords. Cis-2-Hexenol has a very green smell and also more fruity than cis-3-Hexenol.
Synthesis precursor :
Trans-2-Hexenol is a precursor to the synthesis of trans-2-Hexenyl acetate and other esters made from this alcohol.
Synthesis route :
Trans-2-Hexenol is synthesized by the same route as cis-3-Hexenol, or by an isomerization in an acid medium of cis-3-Hexenol.
Stability :
Stable in perfumes and diverse functional bases
Other comments :
Trans-2-Hexenol has a much less powerful smell than trans-2-Hexenal, which has a strong green apple smell. It can then be more easily used in all types of compositions.
