  • Applications

    1-Methylbutyl decanoate (CAS 55195-26-1), also known as isoamyl decanoate, is primarily used as a fragrance ingredient in perfumery, imparting fruity, warm notes to formulations. It is also employed in cosmetics and personal care products as a fragrance component and carrier, helping to deliver stable scent profiles. In household products, it can contribute to the aroma of air fresheners and cleaners. In some coatings and inks, the ester may function as a solvent or processing aid to influence formulation texture and odor. It may be considered for industrial processing applications related to fragrance formulations, subject to formulation limits and local regulations.
