Due to their pH, soap bars are naturally antibacterial, as bacteria cannot multiply with a pH of 9 or more. After hand washing, the pH of hands will be significantly higher and contribute to the viral inactivation of COVID-19. With Coronavirus the soap works to disrupt the fatty acid outer layer of the virus (not bacteria), causing it to dissolve, break apart and consequently wash away.
It is recommended to wash your hands with soap and water often and to do this for at least 20 seconds. Washing your hands properly removes dirt, viruses and bacteria to help stop them spreading to other people and objects.
You can use 70% alcohol hand gel if soap and water are not available, although soap is the preferred and better option. More detailed information on Covid 19 can be found on www.nhs.uk/coronavirus (in the UK).
