Comments on Experimental result regarding Anti-Bacterial soap
After using soap, the pathogens that were previously present in hands are removed by the soap and water. But yes, bacteria from the water do attach themselves to our hands again, for that we should wash our hands with clean water, which may not be sterile but at least free from pathogens. Also if we wipe our hands to cloth after washing, the bacteria that may be present in the cloth adhere itself to human hands. The attachment of bacteria depends on the concentration of microbes, increase in microbial count increases the probability and risk of contamination. Unfortunately antibacterial soaps that use triclosan may kill more microorganisms while washing hands, but then they can't "protect us" from bacteria for some longer periods of time. Also it has been found that antibacterial soaps have the potential to create antibiotic-resistant bacteria, and some may even cause allergies.
