  • Applications

    Lomatiol (CAS 523-34-2) is primarily used as an odorant/fragrance ingredient in perfumery, providing specific aroma notes. It is also evaluated for inclusion in cosmetics and personal care formulations to impart fragrance. In household products such as cleaners and air fresheners, Lomatiol may act as a fragrance additive. In industrial manufacturing, Lomatiol can be used as an intermediate for the synthesis of fragrance compounds or as a fragrance component in process formulations. In some cases, it has been explored for use in coatings or inks as a scent additive, depending on regulatory constraints and formulation limits. Its use, like that of many fragrance chemicals, is subject to local regulations and formulation limits.
