  • Applications

    2,6,8-Trimethyl-4-nonanol (CAS 123-17-1) is primarily used in fragrance-related applications where it serves as an odorant and may act as a fixative due to its higher molecular weight and lower volatility. In cosmetics and personal care, it is evaluated as a fragrance ingredient contributing to scent profiles in products such as perfumes, lotions, and soaps. In household products, it is used as a fragrance component in air fresheners, detergents, and cleaning formulations to impart a lasting aroma. In industrial manufacturing, it can function as an intermediate or specialty solvent in fragrance synthesis and related chemical processes. In coatings and inks, it may be employed as a fragrance-bearing additive or processing aid, helping to influence odor characteristics and formulation properties. In polymers and plastics, it can act as a processing aid or additive during formulation, potentially influencing scent and flow properties.
