"The Food and Drug Administration said recent research raises 'valid concerns' about the possible health effects of triclosan, an antibacterial chemical found in a growing number of liquid soaps, hand sanitizers, dishwashing liquids, shaving gels and even socks, workout clothes and toys.

The FDA and the Environmental Protection Agency say they are taking a fresh look at triclosan, which is so ubiquitous that is found in the urine of 75 percent of the population, according to the Centers for Disease Control and Prevention. The reassessment is the latest signal that the Obama administration is willing to reevaluate the possible health impacts of chemicals that have been in widespread use.

In a letter to a congressman that was obtained by The Washington Post, the FDA said that recent scientific studies raise questions about whether triclosan disrupts the body's endocrine system and whether it helps to create bacteria that are resistant to antibiotics. An advisory panel to the FDA said in 2005 that there was no evidence the antibacterial soaps work better than regular soap and water."
