EmpowHER has had many questions in our very lively ASK section about hand sanitizers. With school back in session and winter approaching (sorry!), looking at the pros and cons of hand sanitizers is a good idea.
Firstly, hand sanitizer does work well. It can kill most germs with one glob on the hand, once it has been rubbed in properly. It’s handy -- most stores, gyms, schools and restaurants have it at the ready.
It can also be toted around in a tiny container in your car, purse or pocket. And it's really useful if there’s no sink nearby or you see Junior rubbing his face after licking the shopping cart.
Hand sanitizers aren’t perfect, though, and can leave germs behind.
According to the CDC, “many studies have found that sanitizers with an alcohol concentration between 60–95% are more effective at killing germs than those with a lower alcohol concentration or non-alcohol-based hand sanitizers.”
However, alcohol-based sanitizers can be very drying to the hands and the more effectiveness you want, the more alcohol is required.
Watching people use sanitizer (and I have), it’s clear many don’t use it properly. A few drops and a quick rub into part of the hand isn’t good enough.
We need to use it the same way as we use soap and water. We need to use a good amount, spending time to make sure it's all over our hands until the sanitizer has dried in.
Do most people actually do this?
Some alcohol-free sanitizers contain something called triclosan. This is an ingredient found in pesticides. Triclosan has been known to cause problems with hormones in animals and has not been found to be any better than soap and water.
When in doubt, avoid chemicals that have shown to be hazardous to animals.
There is also worry over the fact that hand sanitizers can merely reduce the amount of germs on hands and not eliminate them. Germs may come back stronger and develop an immunity to these kinds of hand cleaners.
You may have seen signs that say something along the line of “hand-washing is the single most effective way to limit the spread of germs” and this is true.
