In the constant battle against environmental degradation, ultraviolet (UV) radiation poses a significant threat to the integrity and appearance of numerous materials. From the polymers used in automotive exteriors to the delicate ingredients in cosmetic formulations, protecting against UV damage is paramount. This is where the science of UV absorbers and stabilizers, like 2-Hydroxy-4-methoxybenzophenone-5-sodium sulfonate (CAS 6628-37-1), becomes indispensable.

Known more colloquially as Benzophenone-5 or Sulisobenzone Sodium, this compound is a derivative of benzophenone, a class of chemicals widely recognized for their ability to absorb UV light. The specific molecular structure of Benzophenone-5, featuring a sulfonic acid group as a sodium salt, grants it unique properties, most notably its water solubility and its effectiveness as a light stabilizer.

As a reputable manufacturer and supplier of advanced chemical additives, we provide Benzophenone-5, which is crucial for enhancing the durability and performance of various products. Its mechanism of action involves absorbing UV radiation, particularly in the UVB and short UVA range, and then dissipating this energy through a reversible molecular transformation, effectively preventing it from breaking down the material it protects.

The Scientific Advantages of Benzophenone-5:

  • Photochemical Efficiency: It efficiently converts UV energy into heat, preventing it from initiating photo-oxidation or chain scission in polymers.
  • Water Solubility: The sulfonate group makes it highly soluble in water, enabling its use in aqueous formulations such as water-based coatings, inks, and cosmetics like sunscreens.
  • Synergistic Effects: Often used in combination with other UV absorbers and hindered amine light stabilizers (HALS) to provide a broader and more robust protection system.
  • Chemical Stability: It remains stable under typical processing conditions and during product usage, ensuring long-term effectiveness.
