Terpineol CAS 98-55-5
Terpineol, mainly alpha-terpineol (CAS 98-55-5), is a turpentine derived monoterpene alcohol, a colorless, slightly viscous liquid. It has a sweet lilac and pine note, is nearly insoluble in water and mixes with alcohol and mineral oils. It is used in floral fragrances, soap and detergent scents, food flavors and pine cleaners, and as a solvent, flotation frother and terpinyl acetate feed. UATChem supplies fragrance and industrial grade in galvanized steel drums and IBCs, with COA, TDS and SDS on request.

What Terpineol Is
Terpineol is a monoterpene alcohol made from turpentine, mostly alpha-terpineol with beta and gamma isomers. It is a colorless, slightly viscous liquid with a sweet lilac and pine note. Nearly insoluble in water, it mixes with alcohol and oils. The floral odor and solvency suit it to fragrance and flavor work and to industrial solvent use. UATChem supplies fragrance and industrial grades, with isomer composition and alcohol content on the COA.
Fragrance, Flavor and Industrial Uses
- Fragrances. A common floral body and modifier for lilac, lily of the valley, neroli and pine notes in perfumes, and in soap, detergent and cosmetic scents where a stable floral odor is wanted.
- Flavors. Alpha-terpineol is FEMA 3045 and is used in citrus, nutmeg, peach and spicy flavor formulations; food grade material can be discussed against the destination flavor regulations.
- Cleaners and solvents. Adds a pine scent and solvency to household and institutional cleaners, and serves as a solvent for inks, pigments and electronic cleaning products.
- Chemical and mineral processing. A feed for terpinyl acetate and other ester fragrance intermediates, and a traditional frother in mineral flotation.

Packaging, Documents and Ordering
- Shipped in galvanized steel drums and IBC totes and loaded for export by container, matching the drum and IBC photos on the page. Keep drums sealed in a cool place away from heat and ignition sources; full handling follows the SDS.
- COA, TDS and SDS are provided for every lot, with isomer composition and alcohol content on the COA. Food grade (FG) material for flavor use under FEMA 3045 can be discussed with the matching documents.
- For a quote, UATChem needs the grade (fragrance or industrial), quantity, packing and destination port.
FAQ
Q: What does terpineol smell like and where is it used?
A: It has a sweet lilac and pine note and is used in floral fragrances, soap scents, food flavors and pine cleaners.
