I had this argument with a friend and the dude was so adamant that it was wrong.

This is exactly how hand sanitiser works …

Firstly,most of these sanitizers are alcohol based. They contain upto 60-70 % w/w Alcohol content (IPA or ethanol). I

Sanitisers have high concentration. of highly osmolar liquids such as alcohol

There is no chemical harming the germs ( bacteria ) , but the normal science phenomenon

Due to high osmolality of alcohol , water comes out of the cell membrane of bacteria , making them shrink , they dehydrate and ultimately die …

Our hands have a layer of keratinized ( dead ) cells at the outmost , hence no harm to our body cell

After using sanitiser , let it do it's action , let it dry , and you are ready to chop ur food

In other words,it is perfectly safe to eat with your hands after rubbing hand sanitizer on it

But if your hands are soiled with engine oil and the rest of it,....biko find water and soap
