Benzophenone
Description
Benzophenone is a versatile organic compound widely used in the skincare and cosmetic industries as a UV filter and photostabilizer. This aromatic ketone effectively absorbs and dissipates both UVA and UVB radiation, providing broad-spectrum protection against sun damage. Its molecular structure allows it to absorb high-energy UV rays and convert them into harmless heat, thus shielding the skin from potential photodamage.
In sunscreen formulations, benzophenone is often found in concentrations ranging from 2% to 6%, depending on the desired SPF level and regulatory guidelines. It is particularly valued for its ability to enhance the stability of other UV filters, prolonging the overall efficacy of sunscreen products. Benzophenone also demonstrates excellent solubility in various cosmetic bases, making it suitable for a wide range of product types, including lotions, creams, and sprays.
While generally considered safe for topical use, some individuals may experience skin sensitization or allergic reactions to benzophenone. Recent studies have raised concerns about its potential endocrine-disrupting properties and environmental impact, leading to ongoing research and regulatory scrutiny. As a result, some formulators are exploring alternative UV filters to address these concerns while maintaining effective sun protection.
