Plain soap and water offer the same level of protection that antibacterial soaps do, according to an advisory panel to the FDA. They have found no added benefits to anti-bacterial soaps when compared to regular soap for handwashing.
Moreover, the anti-bacterial chemicals can contibute to the growth of bacteria which are resistant to antibiotics. The panel requested that the FDA evaluate the risks of these products versus the benefit (which they pretty much said was nil.)
This isn't really new news; this has been an assesment of these products for years. I've sought out non-antibacterial liquid soaps for some time, and it's getting harder and harder to find any. The anti-bacterial properties are touted so heavily in advertising that people are convinced they need them; but, we don't. It's nice to have a national body advising the FDA to reassess the use of these products in the home.
