Aug. 17, 2007 -- Antibacterial soaps are no more effective than plain soap and water for killing disease-causing germs, but the jury is still out on whether they promote antibiotic resistance in users, a newly published research analysis shows.
Researchers from the University of Michigan School of Public Health reviewed 27 studies examining the safety and effectiveness of antibacterial products containing the active ingredient triclosan.
That includes most commercially available soaps, detergents and other products with the word 'antibacterial' on their labels, with the notable exception of alcohol-based hand gels.
Soaps containing triclosan at concentrations commonly seen in products sold to the public were found to be no better for killing bacteria and preventing infectious illness than soaps that did not contain triclosan.
"Antibacterial soaps do not provide a benefit above and beyond plain soaps for generally healthy people living in the community," researcher Allison Aiello, PhD, tells WebMD.
"Washing your hands is extremely important for preventing the spread of infectious illness, especially at critical points like after using the toilet, changing the baby, or handling raw foods. But consumers can't assume that antibacterial soaps are better for this than other soaps."
