  • Applications

    Beta-Naphthyl laurate (CAS 6343-73-3) is typically encountered as a fragrance-related ingredient: it can contribute naphthyl notes as an odorant and may act as a slow-release fixative in perfumery and cosmetic formulations. It can serve as an intermediate in the synthesis of other aroma compounds used in flavor and fragrance applications. In household products such as cleaners and air fresheners, it may be included as a fragrance component to impart lasting scent. In coatings, inks, and adhesives, it can be used as a fragrance additive or processing aid to influence odor retention and formulation performance. In industrial manufacturing or polymer systems, it may function as a processing aid or plasticizer in niche formulations where compatible, subject to regulatory limits. These roles are formulation-dependent and subject to local regulations.
