Description

2-Hydroxy-4-(2-Hydroxyethoxy)Benzophenone is a high-performance, water-soluble benzophenone derivative widely used as a UV absorber. Its primary value lies in its exceptional ability to protect materials from photodegradation by absorbing and dissipating harmful ultraviolet radiation. This compound is essential for formulators and manufacturers in the personal care, coatings, and polymer industries seeking to enhance the light stability and longevity of their products.

Application

• Sunscreen & Personal Care Formulations: A key UV filter in sunscreens, moisturizers, and other skincare products to provide broad-spectrum UVA/UVB protection.
• Protective Coatings & Paints: Incorporated into clear coats, wood finishes, and industrial paints to prevent yellowing, cracking, and gloss loss caused by sunlight exposure.
• Polymer & Plastic Stabilization: Used as a light stabilizer in polyvinyl chloride (PVC), polyurethanes, and other polymers to extend service life and maintain color integrity.
• Hair Care Products: Added to hair sprays, gels, and conditioners to shield hair proteins and colorants from UV-induced damage.
• Adhesives & Sealants: Enhances the durability of adhesives and sealants used in outdoor applications by preventing UV degradation.
• Textile Finishing: Applied to fabrics and fibers to create UV-protective clothing and outdoor textiles.
