  • Applications

    Octacosanal (CAS 22725-64-0) is used in fragrance chemistry as an odorant and a fixative in perfumery, where its long-chain structure contributes a fatty, waxy note and helps extend scent life. In cosmetics and personal care, it is commonly evaluated as a fragrance ingredient and may serve as a waxy component or processing aid in formulations such as creams, lotions, and solid sticks. In household products, it can be employed as a fragrance ingredient in cleaners and detergents to impart extended fragrance release. In coatings and inks, it is used as a fragrance additive or component to provide a lasting aroma. In industrial manufacturing, it may be used as an intermediate in the synthesis of fragrance esters and related aroma compounds.
