  • Applications

    Citronellyl ethyl ether, (+/-) (CAS 69929-16-4) is primarily used as a fragrance ingredient in perfumery and cosmetics, providing citrus-floral notes as an odorant and often contributing mild fixative properties to extend scent longevity in formulations. It is also employed as an intermediate in fragrance synthesis and is commonly used in household fragranced products such as air fresheners and cleaners to impart a light citrus aroma; in some industrial settings it may function as a processing aid or carrier in fragrance formulations for various applications.
