  • Applications

    Octocrylene (CAS 6197-30-4) is a lipophilic UV absorber used primarily in cosmetics and personal care products, especially sunscreens, where it provides broad-spectrum UVB/UVA protection and contributes to formulation stability; it also functions as an emollient and solvent/vehicle in cosmetic formulations, aiding dispersion of other actives and improving application feel. In sunscreen blends, it is valued for photostability and can act as a stabilizer for other UV filters such as avobenzone, helping extend overall performance. Beyond cosmetics, octocrylene may be used as a UV absorber/additive in coatings and plastics to enhance UV resistance of non-cosmetic substrates.
