What Should Be the Alcohol Content in Disinfectants?

Disinfectants have become a part of our lives due to the global Coronavirus epidemic we have experienced recently. Since the coronavirus is not resistant to ethyl alcohol, alcohol-based disinfectants are frequently used in this process.

Alcohols show their effect by dissolving lipids and coagulating proteins. Absolute (100%) alcohol has poor antimicrobial effect, as proteins require some water to denature.

Ethyl alcohol is effective at concentrations of 60-95%, but 70% density (v / v) is the alcohol value that shows the best disinfectant efficiency for skin antisepsis.

The high concentration of alcohol used above 70% causes more drying of the skin. Also, as it evaporates more quickly, it causes shorter contact time and also unnecessarily more alcohol consumption.

On the other hand, if the alcohol density is below 50%, the disinfecting feature is largely destroyed. As alcohol evaporates more rapidly than water, the density of alcohol containers left open will soon decrease to ineffective levels.

For this reason, the amount of alcohol is of great importance for alcohol-based disinfectants to be effective. In alcohol-based disinfectants, this ratio should be 70%. Consumers should check whether the amount of alcohol used is at these levels or not on the product label. Manufacturers, on the other hand, should check whether their products contain the correct alcohol content with the tests they will make at certain times.

This test is carried out in our laboratory.
