4terpineol

4-Terpineol, also known as terpinyl acetate, is a naturally occurring organic compound found in various essential oils. It is a monoterpene and a positional isomer of other terpineols. Its chemical formula is C10H18O. It exists as a colorless crystalline solid with a pleasant, floral, and slightly fruity aroma, often described as reminiscent of bergamot or lavender.

This compound is primarily used in the fragrance and flavor industry. Its scent profile makes it a valuable ingredient in perfumes, soaps, and cosmetics, contributing floral and citrusy notes. In the flavor sector, it is employed to impart fruity and herbaceous characteristics to food products and beverages.

4-Terpineol can be synthesized from alpha-pinene, a common constituent of turpentine. It can also be obtained through the fractional distillation of essential oils like eucalyptus oil and cajeput oil, although these natural sources are less common for commercial production compared to synthetic routes.

While generally considered safe for its intended uses in fragrances and flavors, like any chemical compound, excessive exposure or ingestion should be avoided. Its application is regulated by various bodies that set standards for its use in consumer products.
