  • Applications

    Butyl salicylate is primarily used in fragrance applications as an odorant and fixative, helping to impart long-lasting balsamic-floral notes in perfumery and related products. It is also employed in cosmetics and personal care formulations as a fragrance ingredient in creams, lotions, shampoos, and antiperspirants/deodorants. In household products, it serves as a fragrance additive in air fresheners, detergents, and cleaners. It may be used as a solvent or processing aid in fragrance formulations and can function as an intermediate in fragrance synthesis. In coatings and inks, it is sometimes used as a scent additive or solvent to improve fragrance release.
