Every day, consumers use antibacterial soaps and body washes at home, work, school and in other public settings. Especially because so many consumers use them, FDA believes that there should be clearly demonstrated benefits to balance any potential risks.
In fact, there currently is no evidence that over-the-counter (OTC) antibacterial soap products are any more effective at preventing illness than washing with plain soap and water, says Colleen Rogers, Ph.D., a lead microbiologist at FDA.
Moreover, antibacterial soap products contain chemical ingredients, such as triclosan and triclocarban, which may carry unnecessary risks given that their benefits are unproven.
“New data suggest that the risks associated with long-term, daily use of antibacterial soaps may outweigh the benefits,” Rogers says. There are indications that certain ingredients in these soaps may contribute to bacterial resistance to antibiotics, and may have unanticipated hormonal effects that are of concern to FDA.
In addition, laboratory studies have raised the possibility that triclosan contributes to making bacteria resistant to antibiotics. Such resistance can have a significant impact on the effectiveness of medical treatments.
