Antibacterial Chemical disrupts hormone activities
December 10, 2007 05:13 PM - University of California, Davis, Newswire
Davis, California - A new UC Davis study shows that a common antibacterial chemical added to bath soaps can alter hormonal activity in rats and in human cells in the laboratory -- and does so by a previously unreported mechanism.
The findings come as an increasing number of studies -- of both lab animals and humans -- are revealing that some synthetic chemicals in household products can cause health problems by interfering with normal hormone action. Called endocrine disruptors, or endocrine disrupting substances (EDS), such chemicals have been linked in animal studies to a variety of problems, including cancer, reproductive failure and developmental anomalies.
