You know that the best way to prevent the spread of corona virus is to wash your hands or sanitize your hand with sanitizer. So, now sanitize your hand or wash out your hand and lets get ready to know about the hand sanitizer; a little friend of yours or we can say a tiny bodyguard for now.
Alcohol-based hand sanitizers are the ubiquitous little squeeze-bottle heroes of airports and hospitals, our allies against the flu and supposedly effective against all the items that all. But what’s in there? And is it true that they kill 99.99% of germs, as popular brands claim? Most hand sanitizers are alcohol-based. The active ingredient is around 70% alcohol, depending on the formulation. The alcohol are often either ethanol, which is the same stuff that’s in your booze of choice; isopropanol, the things in rubbing alcohol; or n-propanol, rubbing alcohol’s chemical sibling. All of them just about work an equivalent way, which is by dissolving the outer coats of bacteria and viruses and basically exploding them. Alcohol is polar, with water-loving hydroxyl groups. And it likes to disrupt the protein and lipid molecules that structure both bacterial membranes and viral envelopes. When those all-important outer coats fall apart, these disease-causing culprits literally spill their guts everywhere the place, leaving them in no position to form anyone sick. But what about people that never touch hand sanitizer because it'll breed un-killable super-germs which will kill us all? That’s a legitimate concern with antibiotics, which are chemicals that focus on some specific point during a bacterium’s life cycle. The antibiotics in antimicrobial hand soap can cause the emergence of bacterial strains that are resistant and harder to kill. But resistance isn’t really a drag with alcohol-based hand sanitizers. Bacteria can’t develop resistance to having their proteins and membranes blasted. So these alcohol-based hand rubs aren’t going to prevent working? Confirm they're alcohol-based, though some contain antibiotics rather than alcohol, and people do carry the danger of resistance. But alcohol and water alone don't make goo. It’s alcohol that does the germ-murdering, but there’s other stuff in there too. The biggest one is glycerol. Glycerol is chemically an alcohol, but unlike its cousins, it’s in there to not kill germs but to offer the hand sanitizer its gooey consistency that makes it more portable and easier to use. Otherwise it’d be like pouring vodka on your hands. Don’t pour vodka on your hands, guys. Alcohol, water, and glycerol are all you really need to form a DIY hand sanitizer. contribute some peroxide to inactivate bacterial spores, and you’ve got a recipe that gets the U.N.’s seal of approval. But while alcohol is all you would like to kill germs, it’s not all that goes in there. Ethanol and isopropanol can dry your skin. Glycerol helps counteract that effect, but so do a number of other additives manufacturers might put in. This often includes tocopherol acetate, a molecule almost like vitamin E that also happens to be great for your skin, and some familiar stuff like aloe. A number of colors and fragrances might also go in there. None of these are necessary for the hand sanitizer to work, but they could make your hands smell nice. Ethanol-based hand sanitizer may additionally contain bitter or bad-tasting compounds to prevent the tiny percentage of desperate people out there who are willing to drink it because, well, it’s alcohol. So do these chemical goo recipes really kill 99.99% of germs? Those numbers are usually the results of lab testing. But real world is messier and therefore the effectiveness of hand sanitizer varies based on how oily or dirty your hands are, what proportion of alcohol is in there, and which germs you’re actually talking about. Under ideal conditions, some disease-causing germs really do get zapped at that rate, but others don’t. And another thing, hand sanitizers work best together with hand washing, because they don’t physically remove dirt and gunk from your hands. So don’t forget that soap and water. Are you usually packing hand sanitizer whenever you go? Whatever it kill coronavirus or not; just don't forget that using sanitizer reduces the chance of infection. So, that's all for today. Stay safe guys!
