In the realm of material science and product formulation, the impact of ultraviolet (UV) radiation is a significant concern. UV rays can lead to degradation, fading, and loss of structural integrity in a wide array of products, from cosmetics to industrial plastics. This is where UV absorbers and light stabilizers play a crucial role. Among these essential additives, Benzophenone-5, chemically known as 2-Hydroxy-4-methoxybenzophenone-5-sodium sulfonate (CAS 6628-37-1), stands out for its efficacy and versatility.

What are UV Absorbers and Light Stabilizers?

UV absorbers function by absorbing harmful UV radiation and dissipating it as heat, thereby protecting the material they are incorporated into. Light stabilizers, on the other hand, work in conjunction with UV absorbers or by scavenging free radicals generated by UV exposure, further enhancing the material's resistance to photodegradation. Benzophenone-5 is particularly effective as a UV absorber, offering broad-spectrum protection.

The Benefits of Benzophenone-5 (CAS 6628-37-1)

One of the key advantages of 2-Hydroxy-4-methoxybenzophenone-5-sodium sulfonate is its water-soluble nature. This makes it an ideal choice for formulations where water compatibility is paramount, such as in cosmetic sunscreens, water-based coatings, and certain textile treatments. Its high absorptivity ensures efficient protection even at relatively low concentrations. Furthermore, it exhibits good stability to light and heat, which is critical for the longevity of its protective function.

For manufacturers looking to buy this essential ingredient, understanding its specifications is vital. Typically, Benzophenone-5 is supplied as a white or light yellow powder with a purity of 99.0% or higher. This high purity guarantees consistent performance and predictable results in your formulations. As a leading manufacturer and supplier in China, we are committed to providing a reliable source for this high-quality UV absorber.

Applications Across Industries

The application spectrum for Benzophenone-5 is broad:

  • Personal Care & Cosmetics: Its water-solubility makes it a popular choice for sunscreen lotions, creams, and sprays. It helps protect skin from UV damage.
  • Coatings and Paints: Incorporated into automotive, architectural, and industrial coatings to prevent fading, chalking, and degradation caused by sun exposure.
  • Plastics and Polymers: Used to protect plastic products from UV-induced discoloration, embrittlement, and loss of mechanical properties.
  • Textiles: Enhances the UV resistance of fabrics, particularly for outdoor applications.
