Benzophenone-12 is a stabilizer that can also be found in perfumes and soaps. It is an anti-oxidant that helps maintain the properties and performance of a product as it is exposed to air, light or heat. This ingredient should not be confused with Benzophenone-3 (Oxybenzone), which some reports associate with health concerns. Benzophenone-12 is different. It's a commonly used stabilizer that prevents ultraviolet light from damaging scents and colours.
