As a procurement manager or R&D scientist in the cosmetics industry, sourcing high-quality ingredients that ensure product efficacy and longevity is paramount. One such critical ingredient is Benzophenone-4 (CAS 4065-45-6), a widely used UV absorber and photostabilizer. This article aims to provide valuable insights for B2B buyers looking to understand and source this essential chemical from reputable suppliers.

Benzophenone-4, known chemically as 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid, is prized for its ability to absorb harmful ultraviolet (UV) radiation. This makes it an indispensable component in a wide array of cosmetic and personal care products, including sunscreens, lotions, hair sprays, and even nail polishes. Its primary function is to protect both the product formulation and, in the case of sunscreens, the skin from the damaging effects of UVA and UVB rays. By absorbing this energy, Benzophenone-4 prevents photo-degradation, thus maintaining the product's integrity, color, and fragrance over time.

The demand for Benzophenone-4 is driven by its efficacy as a UV filter and stabilizer. For cosmetic formulators, ensuring that their products remain stable under light exposure is crucial for consumer satisfaction and brand reputation. When considering where to buy Benzophenone-4, it's essential to partner with a manufacturer that guarantees high purity and consistent quality. Many international buyers look to China for reliable chemical sourcing, seeking manufacturers who can offer competitive pricing without compromising on product standards. If you are searching for a Benzophenone-4 supplier in China, prioritizing those with robust quality control systems is key.

The technical specifications for Benzophenone-4 typically include a high assay, often 99.5% minimum purity, and it is commonly supplied as an off-white or light yellow crystalline powder. Proper storage, as indicated by manufacturers, is usually in a tightly sealed and light-resistant condition to maintain its efficacy. When researching Benzophenone-4 price options, buyers should compare quotes from several established suppliers to secure the best value for their bulk purchases.

For procurement professionals, understanding the application scope is vital. Beyond its role in sunscreens, Benzophenone-4 acts as a photoprotectant for cosmetic formulations, safeguarding vibrant colors and delicate fragrances from fading. This dual functionality makes it a highly versatile ingredient. Exploring options to buy Benzophenone-4 powder in bulk can lead to significant cost savings and ensure a consistent supply for ongoing production needs.

If your business requires a dependable source for Benzophenone-4, partnering with a leading chemical manufacturer in China can offer a strategic advantage. These suppliers often have extensive experience in global export and can provide the necessary documentation and support for international trade. By focusing on high-purity Benzophenone-4 for your cosmetic formulations, you invest in the quality and longevity of your end products, securing a competitive edge in the market.

In conclusion, for businesses in the cosmetics sector seeking to enhance UV protection and product stability, Benzophenone-4 is a critical ingredient. By diligently researching and selecting a reputable Benzophenone-4 manufacturer and supplier, you can ensure access to a high-quality, cost-effective solution that meets your formulation challenges.
