How a hand sanitizer works

Germs are just yuck, right? But, there isn’t a whole lot you can do to prevent them from existing – all you can do is fight against the germs that are swirling around in the air. This is particularly pertinent if you’re in a hospital, but can also apply to everyday life, and the working world. Keeping yourself clean as much as possible is a great way of making sure you fight against bacteria and stop yourself getting ill.

One of the best approaches to take is to make sure you carry hand sanitizer around with you. This is a great way of keeping yourself germ-free at all times; you can stop and apply some of the sanitizers whenever you need to. So, have you ever wondered how and why this stuff works so well, and why hospitals have so much of it?



However, why is that the hand sanitizer we use doesn’t look or the same as the stuff doctors use to sterilize their tools or even the stuff we drink? Well, the devil is in the detail here. Yes, technically hand sanitizer is made from ethanol, and isopropanol – these are both great for killing and fighting bacteria. However, this only accounts for around 70% of what is found in hand sanitizer, the rest is all additives. These are what gives the product its distinctive smell and gel-like appearance.


Is there such a thing as being too clean? Well, yes. The problem is that if you live in spotless conditions all the time, you are never exposed to any bacteria or germs, which makes your immune system poor. People worry that the continued use of things like hand sanitizers will lead to the birth of super-germs. However, these worries are probably unfounded, as germs do not build up an immunity from the use of things like hand sanitizer.

Be aware

Though hand sanitizer is a positive thing, and it is a good way of helping to keep you cleaner, you should not rely solely on it. While it will provide an extra barrier in the defense against germs and bacteria, but removing the top layer of germs, it can’t be relied upon to clean your hands properly. For that, you need to make sure you are washing your hands properly, with soap. Be aware that hand sanitizer should not be treated as a substitute for washing hands.

So, now you know how hand sanitizer works, and you’ll know what you need to do to make sure you use it properly. Understand what it is, and how it cleans, but realize that it’s not a worthy substitute for properly cleaning and washing your hands. Make sure you use it to add an extra layer of defense, but don’t be overly reliant on it.
