  • Applications

    Dihydromyrcene (CAS 2436-90-0) is primarily used as a fragrance ingredient and odorant in perfumery, often serving as a component in fragrance formulations and, where applicable, as a fixative due to its terpene character. In cosmetics and personal care, it may be employed as a scent ingredient in products such as perfumes, lotions, and bath items. In household products, it can appear as a fragrance additive in air fresheners and cleaners. In industrial manufacturing, it is sometimes evaluated as an intermediate in fragrance synthesis and related formulations, subject to formulation limits and local regulations.
