Commercially available disinfectants like alcohol-based products, soaps, and sanitizers show high efficacy against SARS-CoV-2. Proper concentration and contact time are crucial for effective disinfection against this virus.
Area of Science:
- Microbiology
- Virology
- Public Health
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a significant global health threat.
- Evaluating the efficacy of commercial disinfectants is crucial due to their varied formulations.
Purpose of the Study:
- To assess the virucidal efficacy of 48 commercial disinfectant products against SARS-CoV-2.
- To determine which types of disinfectants are most effective in inactivating SARS-CoV-2.
Main Methods:
- Standardized suspension method (EN 14476) was employed.
- Forty-eight commercially available disinfectant products were tested.
Main Results:
- Alcohol-based disinfectants, hand soaps, wet wipes, alkaline cleaners, quaternary ammonium compound sanitizers, and oxygen bleach demonstrated significant virucidal efficacy.
- Enveloped viruses like SARS-CoV-2 are susceptible to microbicidal actives and detergents.
Conclusions:
- Several common disinfectant types are effective against SARS-CoV-2.
- Optimal disinfectant performance depends on correct concentration and sufficient contact time.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
