Other names :
Acetyver ; Vetyver acetate ; 4,8-dimethyl-2-propan-2-ylidene-3,3a,4,5,6,8a-hexahydro-1H-azulen-6-yl acetate ; Acetivenol ; Vetyverol acetate ; Vetiveryl ethanoate
Volatility :
Base
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.
Natural availability :
Vetiveryl acetate is an hemi-synthetic product, derivated from Vetiver Haiti EO, and particularly from the couple of molecules called Vetiverol.
Year of discovery :
Data not available.
Other comments :
Derivating from Vetiver Haiti EO, Vetiveryl acetate keeps a grapefruit note, compared with Vetiver Java EO, much more smoky.
Price Range :
€€€
Stability :
acetates may form acetic acid through time

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

- Comments :
- According to the IFRA Specification Standard of Allyl esters, Allyl esters should only be used when the level of free Allylalcohol in the ester is less than 0.1%. This recommendation is based on the delayed irritant potential of Allylalcohol. Please also refer to the IFRA Specification Standard Allyl esters.
