For chemists and product developers in the chemical industry, selecting the optimal UV absorber is a crucial step in ensuring the longevity and performance of their products. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid, widely recognized by its acronym BP-4 or its INCI name Benzophenone-4, is a highly effective and versatile UV absorber that deserves close attention. As a dedicated manufacturer and supplier based in China, we offer deep insights into this essential chemical compound.

BP-4 is lauded for its broad-spectrum UV absorption capabilities, effectively shielding materials from damage caused by both UV-A and UV-B radiation. This makes it an indispensable ingredient for applications where light stability is paramount. Its chemical structure, featuring a benzophenone core with a sulfonic acid group, grants it unique properties, most notably its water solubility. This characteristic is a significant advantage, facilitating its incorporation into a wide array of water-based formulations, including cosmetics, personal care products, and water-borne coatings. The ease with which chemists can integrate BP-4 into their formulations simplifies production processes and can lead to improved product aesthetics and performance.

From a technical standpoint, BP-4 offers excellent light and thermal stability, which means it can withstand processing conditions and prolonged exposure to environmental elements without significant degradation. Its low toxicity profile and approval for use in cosmetic applications by regulatory bodies in the EU, USA, and Japan further highlight its suitability for sensitive formulations. For procurement specialists, understanding these technical merits is key when evaluating suppliers. Sourcing BP-4 from a reputable manufacturer in China offers a strategic advantage, providing access to high-purity material at competitive prices, backed by robust quality control measures.
