Concentrations of the sunscreen agent Benzophenone-3 in residents of the United States

The capability of benzophenone-3 (BP-3) to absorb and dissipate ultraviolet radiation facilitates its use as a sunscreen agent. BP-3 has other uses in many consumer products (e.g., as fragrance and flavor enhancer, photoinitiator, ultraviolet curing agent, polymerization inhibitor). The researchers wanted to assess exposure to BP-3 in a representative sample of the U.S. general population ? 6 years of age.
