Vetiveryl acetate

Other comments :

Derivating from Vetiver Haiti EO, Vetiveryl acetate keeps a grapefruit note, compared with Vetiver Java EO, much more smoky.

Stability :

acetates may form acetic acid through time

Uses in perfumery :

Vetiveryl acetate is used in woody, ambery and chypre perfumes for its long-lasting tenacity. Goes well with floral and spicy notes. More delicate and smoky than vetiver but less faceted and woody. Both are often associated in perfumes.

Year of discovery :

Data not available.

Isomerism :

Vetiverol is not a pure compound. It is a mixture of alcohols in which the major compound is Khusimol. Therefore, Vetiveryl acetate is a mixture of esters whose major compound is Khusimyl acetate. Vetyvenal® is a constitutional isomer of Vetiveryl acetate. However, all can be used to reconstitute Vetiver EO.

Synthesis precursor :

Vetiveryl acetate is not a precursor to the synthesis of another compound of olfactory interest.

Natural availability :

Vetiveryl acetate is an hemi-synthetic product, derivated from Vetiver Haiti EO, and particularly from the couple of molecules called Vetiverol.

Synthesis route :

Vetiveryl acetate is prepared from the mixture of sesquiterpene alcohols obtained from Vetiver Haiti EO, Vetiverol, by an esterification reaction using acetic acid or acetic anhydride, in the presence of a catalyst like sulfuric acid. Thus, its synthesis requires a first step to isolate Vetiverol from the vetiver root, which makes it an expensive raw material.
