2,5,5-Trimethyl-2-(2-Methylprop-1-en-1-yl)hexahydro-1-Benzofuran

Ambroxan (INCI: 2,5,5-Trimethyl-2-(2-Methylprop-1-en-1-yl)hexahydro-1-Benzofuran) is a polycyclic ether fragrance molecule that replicates the warm, woody, animalic, and slightly marine scent profile of natural ambergris, historically one of the most prized fixatives in perfumery. It is notable for its exceptionally low odor threshold and its ability to interact with the TRPM8 receptor, producing a subtle skin-warming and sensory-amplifying effect that enhances the wearer's natural scent. Formulators prize Ambroxan not only for its distinctive, long-lasting amber-woody character but also for its outstanding fixative properties, boosting the longevity and diffusion of other fragrance components in fine fragrances, body care, and skin care applications.
