Rumor: The higher the concentration of alcohol, the more effective a disinfectant is.
Fact:
Ethanol at a concentration of 60 to 80 percent proves to be an effective antiseptic, which can deactivate all lipophilic viruses and many hydrophilic viruses.
However, 90 percent alcohol concentration may reduce the effectiveness of disinfection, because the chance of mutation for protein - a major substance contained in the virus - is less without water.
