  • Applications

    Turmerone (CAS 56485‑42‑8), the major sesquiterpene of turmeric essential oil, is used across domains: in pharma/biological R&D as a GC‑MS/LC‑MS reference standard for turmeric oil profiling and as a probe in preclinical studies due to reported anti‑inflammatory, antioxidant, antimicrobial, antifungal, antiparasitic, neuroprotective and neurogenic effects, with emerging roles as an anticancer adjuvant and chemosensitizer; in formulation science it is incorporated into nanoemulsions, liposomes and cyclodextrin complexes to enhance solubility and bioavailability, often in synergy with curcumin; in cosmetics and personal care it provides soothing, antioxidant and barrier‑support benefits and imparts a warm spicy‑woody aroma to fragrances and aromatherapy blends; in foods it contributes natural flavor notes via turmeric oil to spices, beverages and bakery applications; in agriculture it is explored as an insecticidal/repellent, larvicidal, nematicidal and post‑harvest antifungal agent; practical considerations include high volatility, lipophilicity and light/oxygen sensitivity, calling for tight packaging, suitable carriers and compliance with applicable safety regulations.
