In the realm of chemical intermediates, certain compounds stand out due to their broad applicability and essential protective functions. Benzophenone-4, scientifically known as 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid and identified by CAS number 4065-45-6, is one such versatile chemical. Its primary role as a UV absorber makes it indispensable across a range of industries, from personal care to material science. Understanding its properties and applications is key for manufacturers and formulators looking to enhance product performance and longevity.

As a leading manufacturer and supplier of specialty chemicals, we offer Benzophenone-4 in high purity, ensuring its efficacy in demanding applications. Its most recognized use is in the cosmetic industry, where it functions as a crucial sunscreen agent. It provides broad-spectrum protection by absorbing both UVA and UVB radiation, thus preventing sunburn, premature skin aging, and reducing the risk of skin cancer. Its water-soluble nature allows for seamless integration into lotions, creams, and serums, contributing to a pleasant, non-greasy feel—a critical factor for consumer acceptance. When you buy this ingredient for cosmetic formulations, you are investing in proven sun protection technology.

Beyond cosmetics, Benzophenone-4 is a valuable asset in textile finishing. As an anti-ultraviolet finishing agent, it is applied to fabrics like cotton and polyester to shield them from UV-induced damage. This treatment not only preserves the color integrity of textiles, preventing premature fading, but also enhances their anti-aging properties and provides a subtle softening effect. For textile manufacturers, purchasing this chemical intermediate means offering products with superior durability and enhanced tactile qualities.

The utility of Benzophenone-4 extends to other industrial applications as well. It serves as an effective UV absorber for water-soluble inks and paints, protecting them from photodegradation and ensuring lasting vibrancy and performance. This is particularly important for items exposed to sunlight, such as outdoor signage, packaging, and automotive finishes.

For procurement managers and R&D scientists, sourcing Benzophenone-4 requires attention to detail. Key specifications include its CAS number (4065-45-6), molecular formula (C14H12O6S), and assay (typically ≥99.0%). Its physical form is an off-white to light yellow crystalline powder. When considering to buy this compound, it's important to partner with a reliable manufacturer and supplier who can guarantee consistent quality and provide comprehensive technical documentation, such as Certificates of Analysis (COA).

In summary, Benzophenone-4 is a highly versatile UV absorber with critical roles in cosmetics, textiles, and industrial coatings. Its water solubility, broad-spectrum protection, and stability make it a preferred choice for numerous applications. We encourage businesses seeking high-quality Benzophenone-4 to inquire about our manufacturing capabilities and competitive pricing.
