Scientists: Hand washing with soap is more efficient than alcohol Disinfectants, which contain alcohol, are very effective in eliminating viruses, but according to experts, the best method of cleaning hands is with soap and water. Viruses can stay active on the surface of the body for hours and days. Disinfectants, liquids, napkins and creams containing alcohol are effective in eliminating them, but not as effective as washing them with soap and water. But why can a soap work so well in eliminating and killing viruses, including the COVID-19 virus?
The answer is simple: because the virus consists of several nanometric particles, clustered, in which the lipid layer that serves as a link between them is very weak. Given this fact, soap has the ability to easily destroy this lipid membrane and in this case the virus breaks down, and dies or becomes inactive. More broadly, the construction of the virus consists of 3 main components: ribonucleic acid, proteins, and lipids. On the surface, it creates a large number of these components, which then spontaneously accumulate, creating other viruses. When an infected cell dies, all of these viruses are removed trying to infect other cells, some of which end up in the lungs and airways. When you cough or sneeze, these pieces of virus get out of the airways and can spread up to 10 meters in the outside environment.
These tiny pieces end up on the surface and dry out very quickly while the virus stays active. Human skin is a proper environment for the virus to survive, it is “organic” and the proteins and fats found in dead cells serve as their food. If you continue to touch your face with your hands, your eyes or nose will enter the body and you will become infected. Proper handwashing with soap is therefore essential, since soap contains some fatty substances similar to the fatty membrane of the virus and is therefore effective in dissolving it.
