Benzophenone is used to prevent ultraviolet light from damaging scents and colors in products such as perfumes and soaps.
This allows the manufacturer to package the product in clear glass or plastic. Without it, opaque or dark packaging would be used.
It can also be added to the plastic packaging as a UV blocker.
