Safety Profile
GENERALLY SAFEWhat Does Vetiveryl acetate Smell Like?
Vetiveryl acetate opens with a sharp, green-woody character reminiscent of freshly cut vetiver roots. The heart reveals a smoky, earthy depth with hints of dry tobacco and aged leather. Dry-down is a persistent, slightly sweet woody base that lingers close to the skin, evoking images of sun-baked earth after rain.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used to enhance the natural vetiver note, adding a polished woody-sweet facet that balances the raw earthiness of natural vetiver oil.
Provides a smooth, diffusive quality to the dark vetiver core, making the fragrance more wearable while maintaining its mysterious character.

Chemistry, Properties & Perfumer Guide
The Chemistry
Vetiveryl acetate is an acetylated derivative of vetiverol, the primary alcohol found in vetiver oil. The acetylation process increases volatility and modifies the odor profile, making it more diffusive and less harsh than raw vetiver oil. It’s typically produced through esterification of vetiverol with acetic anhydride.
