13990-66-4 Usage
General Description
(2-benzoylphenyl)-N,N,N-trimethylmethanaminium, also known as benzophenone-4, is a chemical compound commonly used in sunscreen and other personal care products as a UV filter. It works by absorbing and stabilizing UV radiation, thus preventing damage to the skin. Benzophenone-4 is a quaternary ammonium compound, meaning it contains a positively charged nitrogen atom linked to four alkyl or aryl groups. This chemical structure helps it to bind to the skin and provide long-lasting protection against UV radiation, making it a popular ingredient in sunscreens and other UV-blocking products. However, there are some concerns about its potential to disrupt hormonal function and its environmental impact, prompting some manufacturers to seek alternative UV filters. Nevertheless, benzophenone-4 remains a widely used ingredient in personal care products for its effective UV protection.
