For R&D scientists and product formulators across various industries, selecting the right UV absorber is critical for ensuring product stability and performance. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid, commonly referred to as BP-4 or Sulisobenzone (CAS 4065-45-6), stands out as a versatile and highly effective ingredient. As a leading chemical manufacturer and supplier, we aim to provide insights into why BP-4 is an indispensable component for many applications.

BP-4's primary advantage lies in its broad-spectrum UV absorption capabilities, covering both the UV-A and UV-B ranges (280-360 nm). This comprehensive protection is essential for preventing photodegradation in a wide array of products, from personal care items like sunscreens and lotions to industrial applications such as water-borne coatings and detergents. Its efficacy in blocking harmful UV rays helps maintain product integrity, prevent color fading, and protect underlying materials from damage.

What further enhances BP-4's utility is its classification as a water-soluble UV filter. This characteristic simplifies formulation processes, particularly in aqueous or emulsion-based systems. Unlike many oil-soluble UV absorbers that require careful emulsification or cosolvents, BP-4 can be readily incorporated, leading to more stable and user-friendly end products. This ease of use is highly valued by product developers seeking efficient and effective solutions. When you decide to buy BP-4, partnering with a manufacturer that ensures high purity and consistent physical properties is key to achieving predictable formulation outcomes.

The regulatory approval of BP-4 in major markets, including the EU, USA, and Japan for cosmetic applications, speaks volumes about its safety profile. For global brands, this broad acceptance simplifies market entry and compliance. Furthermore, its good light and thermal stability contribute to its reliable performance under various processing and environmental conditions. For purchasing managers, identifying a dependable supplier from China, like ourselves, can offer significant advantages in terms of both cost-effectiveness and supply chain reliability.
