Description

Ethyl Decahydro-2,5,5,8A-Tetramethylnaphthalene-1-Acetate is a high-purity synthetic ester derivative of a complex hydrogenated naphthalene structure. This compound is valued for its unique organoleptic profile and high volatility, making it a critical intermediate and functional ingredient in advanced fragrance and flavor creation. It is primarily sought by R&D and production teams in the fine fragrance, personal care, and specialty chemical synthesis industries for its ability to impart sophisticated woody, ambery, and musky nuances.

Application

• Fine Fragrance Formulation: Serves as a key middle-to-base note in premium perfumery, contributing to complex woody, amber, and musk accords with excellent diffusivity.
• Personal Care & Cosmetic Products: Used as a fragrance ingredient in lotions, creams, soaps, and deodorants where a long-lasting, sophisticated scent profile is desired.
• Functional Fragrance for Home Care: Incorporated into high-end detergents, fabric softeners, and air fresheners to provide a distinctive and stable fragrance character.
• Flavor Enhancement: Employed in trace amounts to create or modify complex flavor profiles in specialty food and beverage applications, often contributing earthy or woody notes.
• Chemical Synthesis Intermediate: Acts as a specialized building block for the synthesis of more complex fragrance molecules, pharmaceuticals, or agrochemicals.
• Aromatherapy & Wellness Products: Used in essential oil blends and diffuser products for its potent and distinctive aromatic properties.

Quality Control

Our Ethyl Decahydro-2,5,5,8A-Tetramethylnaphthalene-1-Acetate is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity, consistent olfactory profile, and batch-to-batch reliability critical for fragrance applications. Certificates of Analysis (COA) detailing identity, purity, and specific impurity limits are provided with each shipment. Our quality commitment aligns with IFRA, REACH, and GMP guidelines where applicable.

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/59-77°F). Due to its highly volatile nature, ensure containers are securely sealed when not in use to prevent evaporation and maintain composition. Keep away from heat, sparks, and open flame.
