Description

L-Alpha-Pinene (CAS 7785-26-4 ), also known as (-)-α-pinene, is the levorotatory enantiomer of alpha-pinene, derived primarily from turpentine fractions of coniferous trees. It functions as a bio-based solvent and fragrance ingredient across industrial and consumer product manufacturing. In coatings and printing inks, it acts as a renewable solvent carrier that supports resin dissolution and controlled evaporation profiles suited to high-speed production. Adhesive and sealant formulators use it as a reactive diluent and terpene resin precursor. Its specific optical activity matters for consistent polymer performance in specialized industrial applications. In flavor and fragrance work, it contributes a fresh, piney, coniferous character to fine fragrances, household products, and food flavoring systems. The compound is assigned FEMA 2902 and is widely utilized in the food industry. Personal care manufacturers incorporate it into aerosol sprays, shaving preparations, and scented cosmetics where a natural-origin terpene solvent is preferred. This material is often selected over petrochemical alternatives to meet sustainability goals. L-Alpha-Pinene is supplied as a clear, mobile liquid in drum and IBC quantities for large-scale industrial use and distribution. It is available in fragrance-grade and technical-grade specifications, with high-purity optical isomer grades offered for applications where enantiomeric excess is a formulation requirement. Food-grade material conforming to FCC standards is also commercially available. The product meets rigorous quality benchmarks to ensure stability and performance across diverse sectors. Our supply chain ensures that the material maintains its chemical integrity from the point of distillation to final delivery. Contact us for supply of L-Alpha-Pinene Request Quote
