gammaterpineol

Gamma-terpineol is an isomer of terpineol, a monoterpene alcohol with the molecular formula C10H18O. It is one of several terpineol isomers, alongside alpha- and beta-terpineol. Gamma-terpineol is typically a colorless to pale-yellow liquid and is noted for a floral–woody aroma with pine-like notes.

Natural occurrence and sources: Gamma-terpineol occurs in various essential oils, including pine oil and some citrus oils. It can contribute to the characteristic scents of these oils and is produced or concentrated during the distillation and processing of plant materials.

Uses and applications: In industry, gamma-terpineol serves as a fragrance ingredient and flavor additive in perfumes, cosmetics, and flavored products. It can also be used as an intermediate in chemical syntheses or as a specialty solvent in certain applications.

Production and purification: Commercial gamma-terpineol is typically obtained from essential oils through distillation and purification steps or via catalytic transformations of terpenoid precursors derived from pine or citrus sources. Purification aims to achieve a stable, pure compound suitable for use in fragrances and flavors.

Safety and regulatory considerations: Gamma-terpineol should be handled with standard safety precautions for volatile terpenoids. It can cause skin and eye irritation in some individuals at higher concentrations, and appropriate ventilation, dosing, and personal protective equipment are recommended. It is subject to regulatory guidelines governing fragrances and flavors in consumer products.
