Do hand sanitizers really kill 99.99% of germs? How can they prove that’s true?
In: Biology
They don’t have to test each product.
There are different models of sanitation, and certain methods have defined/researched *log reductions* by the CDC and WHO.
Isopropyl and Ethyl Alcohol is considered a 3 log reduction. If you product has enough alcohol, it qualifies.
Hand washing with proper technique ( e.g. EN 1499 and EN 1500) has a greater log reduction and alcohol based sanitizers should never be used as a replacement for washing hands.
