alpha-terpineol
Description
Alpha-terpineol (CAS 98-55-5), also known commercially as Terpineol, is a naturally derived monocyclic monoterpene alcohol used as a fragrance ingredient, flavor component, and solvent carrier across personal care and pharmaceutical manufacturing.
FEMA 3045 status confirms its recognized use in flavoring applications. Its clean, floral-lilac scent profile drives demand in both functional and aesthetic formulations across various industrial sectors.
In personal care, alpha-terpineol is incorporated into perfumes, soaps, lotions, and hair care products where it contributes a fresh, floral character while also enhancing the penetration of active ingredients through the skin.
Fragrance compounders use it as a building block for lily-of-the-valley and lilac accords in fine fragrance and household product lines. Pharmaceutical formulators rely on it as a solvent and carrier to improve delivery.
This compound helps the dispersibility of active compounds in topical preparations. In flavor applications, it appears in food and beverage systems at low use levels to impart subtle floral-citrus notes to the final product.
Alpha-terpineol is supplied as a colorless to pale yellow liquid. It is available in fragrance-grade and food-grade specifications, with food-grade material conforming to FCC standards for safety and purity.
Bulk supply is standard in drums and IBCs, with smaller packaging available for laboratory and development use. This ensures that both large-scale manufacturers and research facilities can access the material they need.
