Terpineol is a naturally occurring double bond. Terpineol is usually a mixture of these isomers with alpha-terpineol as the major constituent.



Terpineol has a pleasant odor similar to lilac and is a common ingredient in perfumes, cosmetics, and flavors.

Although it is naturally occurring, terpineol is commonly manufactured from the more readily available alpha-pinene.

In one study an alternative route was demonstrated starting from d-limonene [2]:

Limonene is reacted with cis-isomer and trans isomer and 4-terpineol.
