WHO-recommended disinfectants are effective against Sars-CoV-2

Hyperaxion Apr 19, 2020

German virologists have attested that the recommended formulations eliminate the new coronavirus in 30 seconds. With authorization, pharmacies in the country will start to manufacture the disinfectants.

The hygiene habits of the entire population have changed since the beginning of the pandemic, causing an increase in demand for certain products, such as hand sanitizers and other disinfectants. To help meet the demand, the World Health Organization (WHO) has released two extremely effective disinfectant formulations against the new coronavirus.

Researchers in Germany tested the formulations to prove their effectiveness by exposing Sars-Cov-2 for 30 seconds to each of the disinfectants. “This time frame was chosen based on recommendations for hand disinfectants,” says Stephanie Pfänder, a professor in the Department of Molecular and Medical Virology at Ruhr-Universität Bochum, and who led the analysis, in a statement.

The team observed whether the virus remained infectious after 30 seconds and concluded that the formulations recommended by WHO are effective in eliminating the microorganism.


The first disinfectant formulation recommended by WHO consists of 80% by volume of ethanol, 1.45% by volume of glycerin and 0.125% by volume of hydrogen peroxide. The second consists of 75% by volume of isopropanol, 1.45% by volume of glycerin and 0.125% by volume of hydrogen peroxide.

In Germany, pharmacies have received authorization to manufacture disinfectant products with the second formula, based on isopropanol, due to the scarcity of certain products on the market.

Around the world, more than 2.2 million people have contracted Covid-19. Measures of social distancing, washing hands regularly and wearing masks are other WHO recommendations to prevent infection and further spread of the pandemic.
