Benzophenone is used as a photo initiator in UV curing applications such as inks, imaging and clear coatings in the printing industry. The Benzophenone prevents ultra violet light from damaging scents and colour in product such as perfumes and soaps. The Benzophenone can also add to the plastic packaging as a UV blocker. Benzophenone is used as a constituent of synthetic perfumes and as a starting material for the manufacture of dyes, pesticides and drugs.
