Which Is A Better Disinfectant: Ethyl Alcohol Vs. Isopropyl Alcohol

When comparing ethyl and isopropyl alcohol as disinfectants, it’s important to consider the recommendations from the World Health Organization (WHO). According to WHO, a solution containing 70% ethyl alcohol is highly effective as a broad-spectrum germicide and is generally considered superior to isopropyl alcohol for disinfection purposes. Both ethyl and isopropyl alcohols exhibit sufficient germicidal properties. This effectiveness arises from the ability of these alcohols to denature proteins. The WHO’s guidance on this matter was provided on July 6, 2021. In summary, ethyl alcohol with a 70% concentration is favored by WHO as a powerful disinfectant, although isopropyl alcohol can also be effective.

When deciding between isopropyl and ethyl alcohol for disinfection purposes, it’s important to consider scientific research findings. Studies have shown that 70% ethyl alcohol is a highly effective disinfectant, making it generally preferable to isopropyl alcohol in many cases. Both isopropyl and ethyl alcohol can be used to disinfect small surfaces, such as thermometers and external surfaces of equipment. These findings were reported as of December 14, 2021, providing valuable information for individuals seeking the most effective disinfectant for their needs.

Which type of alcohol is most effective for disinfection? When it comes to disinfecting surfaces, 70% isopropyl alcohol outperforms 99% isopropyl alcohol in terms of its ability to kill bacteria and viruses. The reason behind this is that a 70% concentration of alcohol is considered the most effective for eradicating pathogens. It’s crucial to note that using alcohol with a concentration either higher or lower than 70% will be less effective in disinfection. Therefore, for optimal results in your disinfection efforts, opt for 70% isopropyl alcohol.
