A study conducted by researchers
in the College of Life Sciences and Biotechnology, Korea University, Seoul has shown that there was no significant
difference (p > 0.05) between
washing hands with plain soap and antibacterial soaps. The study published in the
Journal of Antimicrobial Chemotherapy
showed that when 20 strains of bacteria, including Streptococcus, Staphylococcus, Listeria and MRSA were exposed to one soap of regular
formation and one containing 0.3 percent triclosan for the recommended 20
seconds of hand washing, there was no difference in the amount of bacteria
killed by the two varieties.
The study reported significant difference in killing more germs in the
triclosan soap only after nine hours, which was a rather long period for
washing of hands said the study. The study was also was experimented with 16
participants using both the soaps and again no difference was found.
The study does raise questions on the effectiveness of the use
antibacterials in soaps, and if further research validates the finding of the
Korean study, shifting to the traditional and cheaper soap and water for hand washing
could reduce unnecessary antibacterial use in daily life.
