Hand sanitizers should contain a Final Alcohol Concentration of 60% to 95%.

💡 Only a commercially prepared hand sanitizer is guaranteed to be effective and safe. I do not endorse any recipes except the WHO ones, and even then only if prepared by someone experienced and with the correct ingredients.

💡 Make DIY recipes at your own risk. Alcohol evaporates during the process, and measurement errors are common even if you are experienced at formulating. In a properly formulated product, the alcohol content is remeasured at the end.
