Chemical Properties

Colorless liquid; odor suggestive of bergamot and lavender. Soluble in five or more volumes of 70% alcohol; slightly soluble in water and glycerol. Combustible.

Chemical Properties

The enantiomers and the racemate occur in many essential oils (e.g., Siberian pine-needle oil and cypress oil), but generally not as the main component. Pure ??-terpinyl acetates are colorless liquids with a fresh bergamot–lavender odor. Commercially available terpinyl acetate consists mainly of ??-terpinyl acetate, but also contains a number of other isomeric compounds such as ??-terpinyl acetate. It can be prepared by acetylating the terpineol mixture obtained from terpin hydrate, using a customary procedure for tertiary alcohols.
Because of its odor properties, stability, and low price, large quantities of terpinyl acetate are used in perfumery for lavender and bergamot types, as well as in essential oil reconstitutions.

Uses

Perfumes, flavoring agent.

Safety Profile

Mildly toxic by ingestion. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
