  • Applications

    1-Cyclohexyl-11-heneicosanone (CAS 182141-50-0) is primarily used in fragrance-related applications, where it serves as an odorant in perfumery and may function as a fixative to help extend scent longevity. In cosmetics and personal care, it can be formulated into fragrance components for products such as lotions, creams, and deodorants. It can also be used in household products, including air fresheners and scented cleaners, to impart a distinctive fatty, waxy note. Industrial settings, it may be evaluated as an intermediate or building block in fragrance chemistry and related syntheses, and may be added as an odorant ingredient in certain specialty polymers or coatings under appropriate formulation controls. Use is subject to local regulations and formulation limits.
