  • Applications

    Patchoulene is a sesquiterpene hydrocarbon present in patchouli oil; its applications center on the fragrance and cosmetics industry where it contributes woody–earthy–resinous nuances, enhances depth and longevity, and acts as a base note in perfumes, soaps, candles, and personal-care items; in flavor work it is used at trace levels to reinforce patchouli-like accords in confectionery, beverages, and flavored tobacco; in agriculture and pest management it is explored as an odorant for masking or to support repellent blends given insect-active properties reported for sesquiterpenes; in biomedical and natural-products research it serves as a reference standard and chromatographic fingerprint marker for patchouli oil and is investigated for antimicrobial, antioxidant, and anti-inflammatory activities; it also functions as a renewable scaffold for semi-synthesis of sesquiterpene derivatives, aroma additives, and slow-release odorant systems in household products, though it is typically dosed at low levels because of volatility and susceptibility to oxidation.
