| Description | α-Vetivone has a powerful, warm,
pleasant, Orris-Vetiver-Ambre-like odor of
outstanding tenacity. It is generally considered
the most desirable odor of the two. Unfortunately, it appears to be the minor component
of the total ketones in Vetiver oil. | | Uses | α-Vetivone, is a component of Vetiver essential oil which is a highly esteemed basic ingredient of modern perfumery, hvaing a woody, earthy scent. | | Definition | ChEBI: Alpha-Vetivone is a sesquiterpenoid. |
