Benzophenone is an organic compound (C6H5)2CO that absorbs ultraviolet (UV) light. Benzophenone is used as a photo initiator in UV-curing applications such as inks, imaging, and clear coatings in the printing industry.
In personal care products, benzophenone prevents UV light from damaging scents and colors in perfumes and soaps.
It can also be added to the plastic packaging as a UV blocker. Its use allows manufacturers to package products in clear glass or plastic. Without it, opaque or dark packaging would be required.
