  • Applications

    Hexacosanal (CAS 26627-85-0) is primarily used as a fragrance ingredient in perfumery and cosmetics, where it provides a long-chain odor profile and can function as an aroma component or a fixative; it is also found in household products as a fragrance additive to impart a lasting scent in detergents and cleaners; in industrial manufacturing it serves as a chemical intermediate for the synthesis of long-chain esters and surfactants used in specialty formulations; and in coatings and inks it may be employed as a fragrance-related additive to enhance or stabilize scent characteristics. Use is formulation-dependent and subject to local regulations.
