  • Applications

    (1R,4aS,8aR)-1,2,4a,5,6,7,8,8a-Octahydro-4-methyl-7-methylene-1-(1-methylethyl)naphthalene (CAS 66141-11-5) is a perhydronaphthalene-type hydrocarbon commonly used as a fragrance ingredient and odorant in perfumery, where it can function as a base note and a potential fixative in complex formulations; it is also evaluated for use in cosmetics and personal care products as a fragrance component; in household products such as detergents and air fresheners as a scent additive; in industrial manufacturing as an intermediate for the synthesis of specialty fragrance compounds; and may be employed in coatings and inks as a fragrance additive or scent modifier, subject to formulation limits and local regulations.
