The science behind effective sun protection and material preservation hinges on the capabilities of UV absorbers. Among these crucial compounds, 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid (CAS No. 4065-45-6), commonly known as Benzophenone-4 or Sulisobenzone, plays a pivotal role. NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of this versatile chemical, facilitating its widespread application across various industries.

Chemically, 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is a benzophenone derivative characterized by its sulfonic acid group, which imparts water solubility. This distinct feature sets it apart from many other UV absorbers, making it particularly suitable for aqueous formulations. Its molecular formula is C14H12O6S, and it typically presents as a white to yellowish crystalline powder.

The primary function of this compound is as a broad-spectrum UV absorber. It effectively absorbs both UVA (320-400 nm) and UVB (280-320 nm) radiation. This comprehensive absorption profile is critical for protecting skin from the harmful effects of sun exposure, such as sunburn, premature aging, and an increased risk of skin cancer. It is for this reason that it is widely utilized in the sunscreen and cosmetics industry.

Beyond its exceptional UV absorption capabilities, 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid is known for its favorable physical and chemical properties. It exhibits good light and heat stability, meaning it can withstand exposure to UV light and heat without significant degradation, thus maintaining its protective efficacy over time. This stability is crucial for product longevity and performance, especially in applications exposed to environmental stressors.

The compound's approval by regulatory bodies such as the FDA as a safe sunscreen ingredient further attests to its reliability. Its low toxicity, as indicated by studies, makes it a preferred choice for applications involving direct human contact. Its utility extends beyond personal care, finding applications as a UV absorber in inks and paints, where it helps prevent color fading and material degradation caused by UV radiation.
