Antibacterial soap – yes or no?

10 09 2009

You gotta love handwashing.  Water, soap, rub, and rinse.  Too easy and gets rid of lots of germs.

The question seems to be: do we need to use antibacterial soap?

Natural soap contains fatty acids that allow oil and water to come together more easily, which in turn allows the water we’re using to carry away the germ-infested oil and grease on our hands.

In the 1990s, antibacterial soaps came on the market for home use.  It seems like using them would be a no-brainer, but experts can’t agree on this.

One concern is whether long-term and widespread use of antimicrobials is contributing to the creation of antibiotic-resistant “superbugs.”

Environmental experts are voicing concern about the long-term effects of triclosan and other chemicals used in these antibacterial products, which are building up in our waste water system, and ultimately being dumped into the environment where they disturb the natural ecosystem by killing desirable and important microbes.

In addition to questions about the environmental impact, the actual effectiveness of these ingredients in household soaps is now in doubt.  Most experts agree that antibacterial soaps are unnecessary in a healthy home setting, and may actually do more harm than good.

A 2004 report in Annals of Internal Medicine found that in a 48-week randomized double-blind study, there was no statistical difference in illness symptoms between the families that used exclusively antibacterial products, and the families that used exclusively non-antibacterial cleaning products.
