  • Applications

    Orin lactone (CAS 134359-15-2) is a lactone used in several real-world applications related to fragrance and chemistry. In perfumery and flavor formulations it functions as an aroma ingredient, often contributing note character and sometimes acting as a fixative to extend odor. In cosmetics and personal care, it is employed as a fragrance component. In household and cleaning products, it can serve as an odorant ingredient. In industrial manufacturing it may be used as a solvent or a chemical synthesis intermediate and as a feedstock for lactone-based polymers or polyesters. In polymer/plastics processing, it can act as a monomer or building block for poly(lactone) materials used in coatings, adhesives, and inks.
