2-(2H-Benzotriazol-2-yl)-6-(isobutene-3-yl)-p-cresol Application
Core Precursor for Advanced Organosilicon UV Absorbers (Core Application): It serves as the essential, direct precursor for synthesizing siloxane-based specialty UV absorbers.
Suncare & Personal Care Formulations: Widely used in high-end broad-spectrum (UVA+UVB) sunscreens, anti-aging skincare products, and UV-protective lotions.
Polymer & Specialty Fiber Light Stabilizer: Featuring an active alkenyl double bond, it functions directly as a reactive or additive benzotriazole-type UV absorber; it is widely used in polyester fibers, engineering plastics, and optical films to significantly enhance the photo-aging resistance and weatherability of polymer materials.
Analytical Reference Standard: Used as a reference standard for impurities in the testing of pharmaceutical and cosmetic raw materials, facilitating quality control and chromatographic purity analysis.
Packaging: 25kg/drum or as customer’s needs
Storage:
Store in a cool, dry, dark, and well-ventilated dedicated chemical warehouse.
Keep strictly away from heat sources, open flames, and direct sunlight; suggested storage temperatures should be maintained under refrigeration at 2 – 8°C.
Keep containers hermetically sealed, nitrogen-blanketed, and protected from light/moisture.
