What is soap and how does it work?Soap is a mixture of fat or oil, water, and lye. Oddly enough, lye is made by leaching wood ashes. Who would have thought that black sooty ash would be the key ingredient in soap? The ingredients are mixed together, heated, and then, through the process of saponification, we get soap.
Soap is made of a lollipop shaped molecule called amphiphiles. The stick end of the amphiphile is attracted to fat, and the round head is attracted to water.
Pathogens stick to the oils and grease on our hands. Rinsing your hands with water is not enough to dislodge viruses and bacteria from the oils on your hand, but the friction of washing, and the amphiphiles, loosen the pathogens and bind them to the water to carry them down the drain. Additionally, the stick end of the amphiphiles can destroy some viruses, including COVID-19, by breaking apart the fatty lipids that keep the virus together.
How to wash hands effectivelyHere’s the proper way to wash your hands according to the CDC .
