For professionals in the cosmetic and chemical industries, the selection of raw materials directly impacts product performance, safety, and regulatory compliance. Benzophenone-4 (BP-4), also known as Sulisobenzone, stands out as a critical UV absorber, particularly valued for its water solubility and efficacy in protecting formulations from photodegradation. As a prominent UV filter supplier, Ningbo Inno Pharmchem Co., Ltd. provides essential insights into sourcing this vital ingredient.

The Role of Benzophenone-4 in Modern Formulations

Benzophenone-4 is a photostable UV filter that absorbs radiation in the UVB and short-wave UVA regions. This dual functionality makes it highly sought after in a variety of applications. Its primary use is in sun care products, where it serves to shield the skin from harmful UV rays. However, its utility extends to stabilizing cosmetic formulations, preventing discoloration, and preserving the integrity of products exposed to light. Its water-soluble nature further enhances its appeal for formulators working with aqueous systems, including cosmetics, inks, and certain types of coatings.

Key Specifications for Benzophenone-4 Procurement

When engaging with a Benzophenone-4 manufacturer, it's crucial to scrutinize product specifications to ensure they meet your formulation's requirements. Essential parameters include:

  • Assay (Purity): Typically, a minimum of 99% is desired for optimal performance and safety.
  • Appearance: A white or light yellow crystalline powder is the standard.
  • Loss on Drying: Low moisture content (e.g., ≤3.0%) is important for product stability and handling.
  • Heavy Metals: Strict limits (e.g., ≤5ppm) are necessary for cosmetic and pharmaceutical applications.
  • Turbidity and Hazen Color: These parameters indicate the clarity and color, influencing the final product's aesthetic.
