Description

Tetrahydronootkatone is a saturated derivative of the sesquiterpenoid nootkatone, prized for its enhanced stability and refined organoleptic profile. This compound is a high-value ingredient for creating sophisticated, long-lasting woody, ambery, and citrus-tinged fragrance accords. It is essential for formulators in the flavor and fragrance industry seeking to impart unique character and improved performance in fine perfumery, personal care, and household products.

Application

• Fine Fragrance Formulation: As a key base note in perfumes, colognes, and eau de toilettes to impart elegant woody, ambery, and vetiver-like nuances.
• Personal Care Products: Used in soaps, lotions, shampoos, and deodorants to provide stable and appealing scent profiles.
• Household & Air Care: Incorporated into detergents, fabric softeners, and air fresheners for a clean, sophisticated aroma.
• Flavor Enhancement: Employed in trace amounts to add complexity and subtle citrus/woody notes to certain food and beverage flavorings.
• Aromatherapy & Wellness: Utilized in diffuser blends and scented candles for its grounding and pleasant olfactory characteristics.
• Chemical Intermediate: Serves as a valuable synthetic intermediate for the production of other specialty fragrance chemicals and pharmaceuticals.

Quality Control

Our Tetrahydronootkatone is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. It is suitable for use in applications requiring FEMA-GRAS and IFRA compliance standards. Every lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, keeping the container under an inert atmosphere (e.g., nitrogen) is recommended.
