Benzophenone-3 (B3)

Description :

Benzophenone-3 is also added to packaging and some consumer products, such as cosmetics and paints, to protect the products from sun damage. Benzophenone-3, often labeled as oxybenzone in sunscreen products, is a widely used chemical compound in cosmetics and sunscreens. Its chemical formula is C14H12O3. This organic UV filter serves as a sunblock agent, absorbing and dissipating harmful ultraviolet (UV) rays, particularly UVB and some UVA radiation.Benzophenone-3 is synthesized through esterification, where 3-benzoylbenzoic acid reacts with phenol, forming benzophenone-3 benzyl ester. Subsequent hydrolysis breaks the ester bond, yielding the benzophenone-3 molecule. Purification processes remove impurities, resulting in a white or pale yellow crystalline powder used in the cosmetic industry.Benzophenone-3 helps protect the skin from sunburn and UV-induced damage, making it a common ingredient in sunscreens, lotions, and lip balms. Despite its effectiveness in shielding against sun damage, concerns about its potential hormone-disrupting properties have led to ongoing research and the exploration of alternative UV filters in the cosmetic industry.Benzophenone-3has raised concerns about potential toxicity and environmental impact. While considered safe for most individuals when applied topically, some studies suggest it may have hormone-disrupting properties. It has also been found in water sources, impacting aquatic ecosystems. Consequently, some consumers and researchers advocate for alternative UV filters in sunscreen formulations. Moreover, if you have acne-prone skin, benzophenones could aggravate your skin and cause breakouts. Having an insect repellent in your sunscreen seems like a convenient time-saver, but it’s less-than-ideal for sun protection and overall health.
