Sunscreen formulations are sophisticated blends designed to protect human skin from the damaging effects of ultraviolet (UV) radiation. Central to their efficacy are UV filters, and among the most recognized classes are benzophenones. Benzophenone, with its characteristic structure, and its derivatives, play a significant role in absorbing harmful UVA and UVB rays. For cosmetic formulators and procurement specialists, understanding the function of Benzophenone is key to developing effective sun protection products.

Benzophenone (CAS 119-61-9) and its derivatives, such as oxybenzone (Benzophenone-3) and sulisobenzone (Benzophenone-4), function as chemical UV filters. When applied to the skin, these compounds absorb UV radiation, converting it into less harmful thermal energy, which is then dissipated. This process prevents the UV rays from penetrating the skin and causing damage, such as sunburn, premature aging, and increased risk of skin cancer. The effectiveness of a sunscreen often depends on the combination and concentration of these UV filters.

While Benzophenone itself is a foundational molecule, its derivatives are more commonly employed directly in sunscreen formulations. These derivatives are specifically designed to offer broad-spectrum protection, covering both UVA (associated with aging) and UVB (associated with sunburn) rays. The stability of these compounds under UV exposure is also critical, ensuring that they remain effective throughout the day. Sourcing high-quality Benzophenone derivatives from reliable manufacturers in China ensures that your sunscreen products meet stringent performance standards.

The inclusion of Benzophenone derivatives in sunscreens is a testament to their proven efficacy. However, ongoing research also explores their environmental impact and potential health considerations, leading to a dynamic regulatory and consumer landscape. For B2B buyers, staying informed about these developments and partnering with suppliers who provide transparent product information and high-purity ingredients is essential.
