    Product Description:
    (+)-Aromadendrene is a naturally occurring sesquiterpene hydrocarbon belonging to the bisabolane class. It is a key constituent of the essential oils from various plants, most notably *Eucalyptus globulus* (blue gum eucalyptus), *Melaleuca alternifolia* (tea tree), and *Curcuma longa* (turmeric). Its characteristic woody, spicy, and slightly camphoraceous aroma profile makes it a valuable component in fragrance and flavor formulations. The primary industrial application of (+)-aromadendrene is as a fragrance ingredient in perfumery, cosmetics, and personal care products, where it contributes to woody, earthy, and balsamic accords. It is also used as a flavoring agent in the food and beverage industry to impart spicy and herbal notes. Beyond its sensory properties, it is studied in research for its potential biological activities, including antimicrobial and anti-inflammatory effects, which are often attributed to essential oils rich in this compound. As a volatile organic compound, it should be handled with appropriate ventilation. It is generally considered safe for use in fragrances and flavors within regulated concentrations, as per guidelines from organizations like the International Fragrance Association (IFRA). Its sourcing is primarily from the distillation of plant essential oils.
