Are there certain elements in soaps that must be present to ensure hands are cleaned properly?
All soaps are composed largely of compounds known as “surfactants”, that have one “hydrophobic” end that attracts oils and fatty substances (such as the outer membrane of bacteria and the outer capsules of enveloped viruses, like SARS CoV-2, the infectious agent behind COVID-19), and a “hyrodphillic” end that attracts water, allowing these oily, fatty substances to be disrupted and washed away with the tap water during hand washing. Provided soap is used, proper hand washing technique and etiquette is the key to ensuring hands are cleaned properly.
