A U.S. FDA advisory committee found that use of antibacterial soaps provides no benefits over plain soap and water for killing bacteria. But that’s not the most important reason to avoid antibacterial soaps.
The main reason to avoid anti-bacterial soaps is its active ingredient: triclosan (and the related triclocarbon). Triclosan is an anti-bacterial chemical found in many consumer products, and it’s nearly ubiquitous in liquid hand soap. It is linked to liver and inhalation toxicity, and even low levels of triclosan may disrupt thyroid function. Further, the American Medical Association recommends that triclosan not be used in the home, as it may encourage bacterial resistance to antibiotics.
