  • Applications

    25-Methyl-10-triacontanone (CAS 151454-16-9) is primarily considered for fragrance-related applications as an odorant and fixative that can contribute woody and waxy notes and help extend scent persistence in perfumery. In cosmetics and personal care, it may be used as a fragrance component within formulations, supporting scent release and longevity while remaining within typical formulation limits. In household products, it can serve as a fragrance additive in cleaners and air fresheners to impart and retain a long-lasting aroma. In industrial manufacturing, it is often evaluated as an intermediate for the synthesis of specialty chemicals or as a building block in organic synthesis. In the polymers/plastics and related coatings/inks sectors, it may be explored as a processing aid or formulation modifier, potentially influencing flow, compatibility, or fragrance delivery in finished products. Subject to local regulations and formulation constraints.
