  • Applications

    Menthyl pyrrolidone carboxylate (CAS 506412-91-5) is commonly used as a solvent and fragrance carrier in perfumery formulations, aiding solubilization and stabilization of volatile aroma components. In cosmetics and personal care, it acts as a solvent or solubilizer for active ingredients and fragrance. In coatings, inks, and adhesives, it serves as a solvent and processing aid to improve mixing and formulation stability. It is used as a solvent or processing aid in polymer/plastics systems to dissolve or disperse plasticizers and other additives. Additionally, with good solvency and compatibility with various polymers, it can function as a cleaning solvent in industrial and consumer applications. Overall, primary use areas include solvent/solubilizer for fragrances and cosmetics; solvent/processing aid for coatings, inks, and adhesives; solvent for polymer/plastic systems; and cleaning applications.
