  • Applications

    Musk xylene (CAS 81-15-2) is a synthetic musk fragrance ingredient used in perfumery as an odor component and fixative to extend and stabilize scent; it is also employed in cosmetics and personal care products as a fragrance ingredient and fixative; in household products such as cleaners and detergents it appears as an odorant or fragrance additive; and it may be used as a fragrance additive in polymer/plastic formulations and textile-related materials to impart or preserve scent in various end-use applications.
