  • Applications

    Monoterpene hydrocarbons (unknown) are widely used as fragrance ingredients in perfumery and cosmetics, and as flavor/aroma additives in foods and beverages. They also function as low-toxicity solvents and processing aids in cleaning products, coatings and inks. In industrial chemistry they serve as versatile chemical feedstocks and intermediates for the synthesis of fragrances, flavors and specialty polymers, and some monoterpenes are polymerizable or convertible into resins and biobased solvents. Additionally, they act as odorants or natural fixatives in formulations, subject to local regulations and formulation limits.
