Dry, clean vetiver, less earthy and smoky than the oil; woody with a light grapefruit touch.

History

Vetiveryl acetate is made by acetylating vetiver oil or its alcohol fraction. Because the starting material is an essential oil, the product is a mixture of many sesquiterpenyl acetates rather than a single molecule.

In perfumery

Vetiveryl acetate gives a cleaner, brighter vetiver than the oil and is widely used in masculine, chypre and woody fragrances.
