What Chemicals Kill Coronaviruses?

Scientist Richard Lowe, explains that there is some good news about the COVID-19 or the Corona virus. "A coronavirus is what's called an envelope virus and that means it has an outer envelope that's composed of proteins and a fatty material called a lipid, and it's that outer layer that makes it relatively simple to kill with MOST disinfectants, compared to other viruses that don't have that envelope."


Once you have a disinfectant, you need to make sure to use it correctly. Read the product label. Generally one must apply, allow the product to dwell, usually visibly wet, to ensure that you kill viruses and bacteria.


In the document 'European Centre for Disease Prevention and Control. Interim guidance for environmental cleaning in non- healthcare facilities exposed to SARS-CoV-2. ECDC': European Centre for Disease Prevention and Control:


Several antimicrobial agents have been tested against different coronaviruses (Table 1). Some of the active ingredients, e.g. sodium hypochlorite (contained in the household bleach) and ethanol are widely available in non- healthcare and non-laboratory settings.Suggested citation:

A recent paper which compared different healthcare germicides found that those with 70% concentration ethanol had a stronger effect on two different coronaviruses (mouse hepatitis virus and transmissible gastroenteritis virus) after one minute contact time on hard surfaces when compared with 0.06% sodium hypochlorite. Tests carried out using SARS-CoV showed that sodium hypochlorite is effective at a concentration of 0.05 and 0.1% after five minutes when it is mixed to a solution containing SARS-CoV. Similar results were obtained using household detergents containing sodium lauryl ether sulphate, alkyl polyglycosides and coco-fatty acid diethanolamide

The use of 0.1% sodium hypochlorite (dilution 1:50 if household bleach at an initial concentration of 5% is used) after cleaning with a neutral detergent is suggested for decontamination purposes, although no data on the effectiveness against the SARS-CoV-2 are available. For surfaces that could be damaged by sodium hypochlorite, 70% concentration of ethanol is needed for decontamination after cleaning with a neutral detergent.Cleaning should be performed using the proper personal protective equipment (PPE).
