  • Applications

    Cyperol is primarily used as a fragrance component in perfumery, functioning as an odorant and, where applicable, as a fixative to help extend scent in finished formulations. It may be employed in cosmetics and personal care products as a fragrance ingredient, contributing to fragrance profiles in creams, lotions, and cleansers. In household products and cleaners, it serves as a fragrance additive to impart lasting scents. It can be used in coatings and inks as a scent additive to impart aroma to decorative materials or packaging. In industrial manufacturing, Cyperol may be used as a processing aid or intermediate in fragrance-containing formulations, subject to local regulations and formulation limits.
