Uses
Benzophenone can be used as a photoinitiator in UV(Ultra-violet)-curing applications such as inks, imaging, and clear coatings in the printing industry. Benzophenone prevents ultraviolet (UV) light from damaging scents and colors in products such as perfumes and soaps. Benzophenone can also be added to plastic packaging as a UV blocker to prevent photo-degradation of the packaging polymers or its contents. Its use allows manufacturers to package the product in clear glass or plastic (such as a PETE water bottle).Without it, opaque or dark packaging would be required. In biological applications, benzophenones have been used extensively as photophysical probes to identify and map peptide–protein interactions. Benzophenone is used as an additive in flavorings or perfumes for “sweet-woody-geranium-like notes.
