Health Canada's warning of health risks from homemade hand sanitizers.
Noting homemade recipes and products are becoming increasingly common online, the federal health agency warns many of the products lack a high enough concentration of alcohol to kill the coronavirus that causes COVID-19 - and various formulas could present other health risks such as skin irritation, increased sensitivity, or allergies.
Health Canada's recommending against making hand sanitizer - no matter the recipe, even a reputable formula recommended by the World Health Organization - as only licensed producers can manufacture in a controlled environment to ensure accurate concentration.
Instead, it's recommend you wash hands often with soap and water for at least 20 seconds, though a Health Canada-approved hand sanitizer with an alcohol concentration of at least 60% will work as a lesser alternative.
