Benzophenone-6

Benzophenone-6 (CAS 131-54-4) is a UV-absorbing compound sold under trade names including Uvinul D49, Uvinul 3049, and Seesorb 107. It belongs to the benzophenone family of organic UV filters and functions by absorbing ultraviolet radiation and dissipating it as heat, preventing photodegradation of the substrate.

In polymer coatings and plastics, Benzophenone-6 intercepts UV radiation before it can break polymer chains, extending service life of the finished material. In personal care formulations, it acts as a photoprotective agent, absorbing UV energy to reduce photodamage. It also serves as an antioxidant and heat stabilizer in printing inks and adhesive systems.

Benzophenone-6 is supplied as a yellow crystalline powder and falls under REACH registration requirements for EU market supply. Procurement teams should confirm supplier SDS documentation and purity specifications prior to ordering. Standard packaging formats vary by supplier; bulk and drum quantities are typically available for industrial buyers.
