Description

Terpinolene (CAS 586-62-9 ), also listed under FEMA 3046 , is a naturally occurring monocyclic monoterpene found in pine, sage, and various citrus oils. It functions as both a flavoring ingredient and a solvent carrier across food, fragrance, and industrial applications. In flavor and fragrance formulations, terpinolene contributes fresh, piney, floral top notes to perfumes, soaps, and scented personal care products. Food manufacturers use it as a FEMA-approved flavoring agent in baked goods, beverages, and confectionery. In printing inks and coatings, it acts as a bio-based solvent carrier that supports resin dissolution and controlled drying profiles. Its terpene-derived solvent character also makes it relevant in cleaning formulations and as a diluent in specialty chemical processes. Terpinolene is supplied as a clear mobile liquid, typically in drum and IBC quantities suited to industrial and commercial buyers. It is available in fragrance-grade and food-grade specifications depending on end-use requirements. Purity levels commonly range from 85% to 95%+, with higher-purity isolates available for flavoring and cosmetic applications. This versatile monoterpene is essential for manufacturers seeking natural alternatives to synthetic solvents and aromatic compounds. The material is handled according to strict quality standards to ensure consistency across batches. Buyers can rely on its stable chemical profile for integration into complex formulations requiring specific volatility and odor characteristics. Contact us for supply of Terpinolene Request Quote
