Someone told me that they saw on the news that hand sanitizer doesn't work?!
Question: She said that the things like Purrell or whatever the brand doesn't have enough alcohol in it to kill the germs in things like staff infections and colds. Is this true? Can you give me links to facts to prove its true or untrue?
Thank you!

Hand sanitizers do their job, but shouldn't be substitued for hand washing too much. They kill bacteria, the weak bacteria though. It's like a war, of course the strongest are going to survive, but then that leaves you with JUST the strong bacteria with no enemies to battle it out with. So actually, it might be better to not use the hand sanitizer too much, or all those good germs we're carrying around will die off and won't be able to help us anymore. The news is dumb, I've realized its uniformitive and never gives details, theyre always gonig for the shock value. hope this helps
Ok....
it is and isn't true.
What they claim they do, is correct...
the problem comes in when it isn't concentrated to kill every single bacteria, because then they adapt... just like when you don't finish an antibiotic drug.
It's a scary thought but we REALLY need to lay off the hand sanitizers and antibacterials or we are going to all be very sick.
We NEED to give our immune systems a chance to learn to fight things!
The alcohol content has to be above 60 percent in order to do an adequate job

It has 62% alcohol. (Purell website)
The optimum alcohol concentration to kill germs is 70 to 95 %. Alcohol gels containing 62 v/v % alcohol are less effective germ killers than alcohol rubs containing at least 70 wt/wt % alcohol. (Wikipedia)
Your sick, I don't have any hands. I bet you will never see any feet sanitizer.
Yah, that's a half-truth. Hand sanitizers do about the same job as simple soap and water. So why take the chance of teaching harmful bacteria how to survive our best disinfectants? They do kill MOST bacteria. But the survivors follow Darwin's instructions for destroying our world.
Alcohol is a biocide.
I say fair play to any bacterium that is able to become resistant.
It is true to say that washing with soap and water is as effective as the alcohol gels, so its cheaper if nothing else to go for the soap.
There's several types of hand sanitizers with different chemicals and different combinations and some work and some do not. Sanitizers based on alcohol - such as Purell are very effective if the alcohol concentration is high enough, but they aren't perfect. Alcohol kills nearly all bacteria on contact, but it doesn't necessarily eliminate all viruses. Some sanitizers also contain phenol, which is even more effective than alcohol, but its so powerful, it removes proteins from your skin, which causes dryness or irritation.
Another effective sanitizer is a product such as Hibiclens which contains Chlorhexidine Gluconate. This is also a very effective anti-microbial chemical, but you have to wash your hands for about 5 minutes to kill all the germs.
Lastly are the common anti-microbial hand soaps containing Triclosan - these are nearly worthless and probably do more harm than good. It takes Triclosan maybe 20 minutes to kill all the germs, so the only thing accomplished by Triclosan is to create resistant bacteria that are even harder to kill.
