  • Applications

    Octinoxate (CAS 5466-77-3) is primarily used as a UV absorber in cosmetics and personal care products, including sunscreens, lotions, and makeup. It may also be employed as a UV stabilizer in polymer and plastic formulations to reduce photodegradation, and as an additive in coatings and printing inks to improve UV resistance. In some household and consumer products containing plastics, it can help extend outdoor durability under sunlight.
