Illinois researcher receives award for developing a better sunscreen

Craig A. Bonda of the C.P. Hall Company in Bedford Park, Ill., will be honored June 11 by the world's largest scientific society for developing a better, longer-lasting sunscreen. He will receive one of four 2001 Industrial Innovation Awards at the American Chemical Society's Central/Great Lakes joint regional meeting in Grand Rapids, Mich.

"Craig's unique combination of technical expertise and commercial development experience has positioned the C.P. Hall Company as an innovative technology leader in advanced additives for sunscreen applications," said John J. Paro, executive vice president and chief operating officer for the C.P. Hall Company.

Until recently, most sunscreens protected wearers only against UVB — the ultraviolet rays that cause sunburn. The newest sunscreens absorb or reflect the full spectrum of ultraviolet radiation, including UVA, which causes skin to age and wrinkle prematurely, and may also cause certain skin cancers.

Avobenzone, a chemical used in many full-spectrum sunscreens, loses its effectiveness upon prolonged exposure to the sun. Bonda found that avobenzone breaks down more slowly when the chemical DEHN is added. In one experiment using two avobenzone-based sunscreens — one with DEHN and one without — the DEHN sunscreen maintained most of its effectiveness after five hours while the other lost almost all of its UVA protection. Full-spectrum sunscreens with DEHN were introduced to U.S. consumers earlier this year.

The American Chemical Society's Industrial Innovation Awards recognize individuals and teams whose discoveries and inventions contribute to the commercial success of their companies and enhance our quality of life.
