There are two formulas that are used. Each formulation contains a certain type of alcohol and different concentrations of hydrogen peroxide, as follows:
The WHO recommend two alcohol-based sanitizer formulations to prevent the spread of pathogens in general.
Now, scientists in Germany and Switzerland have tested the sanitizers’ effectiveness against SARS-CoV-2.
The first sanitizer comprises:
ethanol — 80% by volume (vol/vol)
glycerine (also known as glycerol) — 1.45% vol/vol
hydrogen peroxide — 0.125% vol/vol
The second sanitizer comprises:
isopropanol (also known as 2-propanol or isopropyl alcohol) — 75% vol/vol
glycerine — 1.45% vol/vol
hydrogen peroxide — 0.125% vol/vol
The researchers exposed SARS-CoV-2 virus particles to each formulation for 30 seconds.
