Description

α-Terpineol is a naturally occurring monoterpene alcohol widely valued for its pleasant lilac-like aroma and versatile chemical properties. It serves as a key intermediate and functional ingredient across multiple high-value industries, offering a blend of fragrance, solvent power, and antimicrobial activity. This compound is essential for manufacturers in the fragrance, flavor, pharmaceutical, and agrochemical sectors seeking a reliable, high-purity building block.

Application

• Fragrance & Perfumery: A primary component in soaps, detergents, cosmetics, and fine perfumes for its fresh, floral scent reminiscent of lilac.
• Flavoring Agent: Used in food and beverage formulations to impart citrus and pine notes, often in conjunction with other terpenes.
• Industrial Solvent & Intermediate: Acts as a solvent for resins and waxes, and as a chemical intermediate in the synthesis of other terpene derivatives and fine chemicals.
• Pharmaceutical & Disinfectant Formulations: Utilized for its antimicrobial and antiseptic properties in topical disinfectants, mouthwashes, and certain medicinal preparations.
• Agrochemicals: Employed as a solvent or synergist in pesticide formulations and as a starting material for producing insect repellents.
• Household & Industrial Cleaners: Incorporated for its dual function as a fragrance and a cleaning agent in various cleaning products.

Quality Control

Our α-Terpineol is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. We offer grades suitable for fragrance, flavor (FEMA 3045), and technical applications, with specifications tailored to meet customer requirements. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized, storage under an inert atmosphere (e.g., nitrogen) is recommended for long-term preservation of quality. Recommended storage temperature: 15-25°C.
