Benzophenon-3 is a naturally occurring chemical found in some flowering plants. BP-3 absorbs and scatters the suns harmful ultraviolet (UV) rays. For this reason, it is produced for use as sunscreen in lotions, conditioners, and cosmetics. It is a common, FDA-approved active ingredient in many sunscreen products. By absorbing UV rays, it also helps preserve the integrity of other cosmetic ingredients, preventing their deterioration under the sun. Benzophenon-3 is most often used in conjunction with other sunscreen agents. Besides sunscreen, it can be found in a variety of personal care products such as nail polish, lotions, and lipstick.
