  • Applications

    2-(2,5,5,8a-Tetramethyl-1,4,4a,6,7,8-hexahydronaphthalen-1-yl)acetaldehyde is encountered primarily as an aroma compound and fragrance intermediate; in perfumery it can serve as an odorant and, where appropriate, as a fixative to help extend fragrance notes. In cosmetics and personal care, as well as in household products, it is used as a fragrance ingredient at controlled concentrations. In industrial manufacturing, it may function as an intermediate in fragrance- and flavor-related chemical syntheses and can be used in scented coatings/inks, subject to local regulations and formulation limits.
