Product Technical Details

Product Overview

UV Absorber Benzophenone-6, chemically known as 2,2'-Dihydroxy-4,4'-dimethoxybenzophenone, represents a critical class of water-soluble ultraviolet filtering agents utilized across the cosmetic and textile industries. As a neutral broad-spectrum benzophenone derivative, this compound exhibits exceptional efficiency in absorbing high-energy UV radiation. Our manufacturing process ensures a high level of purity, making it an ideal choice for formulators seeking reliable photostability and product longevity. The substance functions by selectively absorbing harmful ultraviolet rays and converting this energy into harmless low-energy radiation or heat, thereby preventing degradation of the host matrix.

Industrial Applications

The versatility of UV Absorber Benzophenone-6 allows for widespread application in multiple sectors. In the personal care industry, it is primarily employed in water-soluble chemical sunscreens, protective lotions, and after-sun care products. Its water solubility facilitates easy incorporation into aqueous phases without compromising the sensory feel of the final formulation. Furthermore, it is utilized in hair care products such as gels and mousses to prevent UV-induced damage and whitening of hair fibers. Beyond cosmetics, this chemical serves as an effective light stabilizer for textiles. It significantly improves the color durability of dyed fabrics, prevents the yellowing of wool textiles, and safeguards synthetic fibers from discoloration caused by prolonged sun exposure.
