Washington — The Food and Drug Administration announced Friday that it is banning the sale of some antibacterial soaps and washes, saying the products are no more effective than conventional soap and water in preventing illnesses and may not be safe to use over long periods of time.

The rule applies to products — such as liquid soaps, bar soaps and body washes — that contain one or more of 19 active ingredients, including the most commonly used, triclosan and triclocarban. Manufacturers will have one year to reformulate their products or take them off the market, the agency said.

“Consumers may think antibacterial washes are more effective at preventing the spread of germs, but we have no scientific evidence that they are any better than plain soap and water,” Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research, said in a statement. “In fact, some data suggests that antibacterial ingredients may do more harm than good over the long term.”

The rule does not affect consumer hand sanitizers, wipes or antibacterial products used in hospitals and other health care settings.
