  • Applications

    (-)-Curcumol (CAS 4871-97-0) is a sesquiterpenoid constituent found in Curcuma essential oils. In industry, it is commonly evaluated as a fragrance ingredient for perfumery and cosmetics/personal care, and can be used in household products as a fragrance additive. It also serves as a chemical intermediate for the synthesis of sesquiterpenoid derivatives in industrial manufacturing. Additionally, it may function as an odorant in coatings/inks and as an aroma contributor in polymer formulations, subject to regulatory and formulation limits.
