  • Applications

    Alpha-Campholene acetate (CAS 1727-68-0) is used as a fragrance ingredient in perfumery, often acting as a fixative and odorant to help stabilize and extend notes in camphoraceous scent profiles. It is commonly employed in cosmetics and personal care formulations as a fragrance component, and it also appears in household products such as air fresheners and cleaners to contribute aroma. In industrial manufacturing, it can serve as an intermediate for the synthesis of other aroma chemicals used in fragrance portfolios.
