  • Applications

    Ascorbyl Linoleate (CAS 121869-32-7) is an ester of ascorbic acid with linoleic acid, primarily used in cosmetics and personal care as an antioxidant and skin-conditioning agent, helping to stabilize oil-containing formulations and improve skin feel and moisturization. It is also evaluated as a stabilizer and antioxidant for polymer and plastic systems, and is often used in coatings, paints, and inks to mitigate oxidation and extend product durability. In pharmaceutical formulations and as an excipient, it can serve as an esterified vitamin C component or antioxidant, used within applicable limits and regulatory requirements. Additional potential applications include acting as a stabilizer for multi-component polymer formulations and as a protective ingredient in complex formulations.
