Description

Nootkatone is a naturally occurring sesquiterpenoid ketone prized for its distinctive grapefruit-like aroma and potent bioactivity. This compound matters significantly as a high-value flavor and fragrance ingredient and as an emerging active agent in pest management and personal care. It is essential for manufacturers in the flavor & fragrance, food & beverage, cosmetic, and agricultural industries seeking natural, effective, and compliant ingredients for their formulations.

Application

• Flavor & Fragrance Industry: A key component in perfumery for citrus and woody accords, and in food flavorings for beverages, confectionery, and dairy products.
• Food & Beverage: Used as a natural flavoring agent to impart fresh grapefruit notes to soft drinks, alcoholic beverages, and culinary products.
• Cosmetics & Personal Care: Incorporated into skincare, haircare, and toiletries for its refreshing scent and potential skin-conditioning properties.
• Insect Repellents & Pest Control: Serves as an effective, natural active ingredient in EPA-registered repellents for ticks, mosquitoes, and other insects.
• Aromatherapy & Wellness: Utilized in diffuser blends and therapeutic products for its uplifting and energizing aromatic profile.
• Pharmaceutical Intermediates: Acts as a valuable chiral building block in the synthesis of more complex organic molecules.
