What is Benzophenone-4?

  • Benzophenone-4, also knowns as Sulisobenzone, is a water-soluble UV filter. It is a protective ingredient that works to keep the UVB rays away from the skin and hair, also is commonly used for other purposes such as extending the shelf lives of products and acting as a color protectant.

Features of Benzophenone-4

  • Photostabilizer. It is a chemical sunscreen agent used for its ability to absorb UV rays. It helps prevent the integrity of other cosmetic ingredients from deteriorating under the sun.
  • High efficiency. Concentrations of as low as 0.1% provides good results. Though it covers UVB and short UVA (UVA-2) range rays, it’s an inadequate sunscreen agent when used alone. For this reason, it is often used in conjunction with other sun protecting ingredients.
  • Wide application. It’s used in a variety of personal care products like sunscreen, nail polish, lotion/cream and lipstick, also as ultra-violet stabilizer in wool, cosmetics, pesticides &lithographic plate coating.
