History

Khusimol is one of the main sesquiterpene alcohols of vetiver oil, often a large share of its alcohol fraction. The name comes from khus, the Indian name for vetiver.

In perfumery

Khusimol is not commonly sold as a separate material; its main role is as a constituent that shapes the odor of vetiver oil and vetiveryl acetate.
