Hi we thought the mass hysteria surrounding the novel coronavirus or covert 19 faced dogs and cats living Together mass hysteria I thought I'd show you how to make your own hand sanitizer like this with that stuff you should have lying around your lab. Now this is not new for us, as in the Eevblog family. We've been carrying a hand sanitizer like this for Donkey's years. in particular, Mrs.

Eevblog who is a scientist, a chemist and is up on these sorts of things so it's particularly are pertinent in today's climate now. I I think I tweeted back in late January or something how that mass hysteria had already started to take off in terms of like hand sanitizer just vanished overnight from all the stores in Australia and online and everything else. all those little hand sanitizers that you pay a premium for, but it's really easy to make these yourself. and I'll show you now if you don't know, the novel coronavirus can actually be fairly easily broken down and you know effectively are deactivated.

Really, you could say destroyed, but effectively are deactivated relatively easily just using alcohol like isopropyl alcohol or ethyl alcohol. but your lab should have isopropyl alcohol because we use this in electronics to clean our PCBs and other stuff like that. So yeah, if you don't have isopropyl alcohol in your lab, you should I or I always keep a couple of liters available. but when this thing happened I was almost I was getting that quite low on my isopropyl.

So back in like early February I am ordered another hour, five liters and I you know this is like cheap stuff. Isopropyl alcohol, you should have it. It's like like 15 bucks for five liters or something like. it's really cheap stuff although they might be price gouging these days.

So I thought I'd show you how to make little hand sanitizers like this that you can just carry around. and one of these are 50 ml bottles you can pick these up on eBay for you can get like a dozen of these for like 5 bucks delivered. They're an atomizer spray so as you can see, you might be able to see I really I Like puts out a really fine mist and you just rub it on your hands. Fillie If you know decent, spend a bit of you know effort actually doing this.

and if you do that thoroughly enough hopefully like it's not guaranteed. But it does help deactivate all sorts of bacteria. and yes, also viruses. Because if you don't know, the novel coronavirus is an RNA virus is both DNA and RNA viruses.

But these sorts of alcohols. These are effective against any sort of what's called a lipid virus. So in this particular case, the normal corona virus actually contains an outer shell of proteins. It's fairly easy to break down those proteins with a water and in either ethyl alcohol or isopropyl alcohol.

Both of these basically anything over 60% dilution ratio Basically 60% alcohol will actually deactivate all sorts of stuff. Will deactivate Corona virus in particular novel Coronavirus. it deactivates Influenza Herpes Herpes is actually a our DNA virus, not an RNA virus like the Corona virus, Hepatitis B and all sorts of other stuff. So you know if you don't catch herpes off its surfaces people you know then with those cold sores got to watch out for him then I.

So probably alcohol is useful against all sorts of our viruses and other bacteria. It's great stuff. So what happens then is the virus just like loses its bonds so to speak. It's just pretty much just falls apart and dissolves into the water and becomes effectively inactive or denatured.

So basically if you mix 60 at least 60% isopropyl alcohol, 70% to like 80 percenters. Kind of like their recommended value. which is why these medical swabs which you've seen me use in various videos for cleaning up stuff real handy little things. These are 70% isopropyl alcohol.

These are medical swabs which I get in hospitals and things like that. So if you're in the hospital and they're about to you know stick a needle into you or something like that then might rub you down. This should wrap you down with a like an isopropyl just to get rid of any bacteria or viruses just hanging around to clean it up. So they're always almost always our 70% So if you've got to mix your own 70 percent good value.

So what actually happens is the isopropyl alcohol. The ethyl alcohol molecules and the water molecules actually combine with the outer lipid shells of the proteins of the virus and effectively are break them down or what's called denature them and then effectively. Yeah, there, they become effectively inactive. so at that point you've pretty much killed it.

But it's called denaturing now. Of course, it's not guaranteed to be a hundred percent effective because of the Corona virus. It looks like it's like airborne as well, so you could be breathing it in or whatever. but at least you're taking some measures to actually protect yourself from like surface contacts and things like that.

So when you get it on your hands and then you go touch your face like hundreds of times a day as your average person does. By the way, for the last several months I've been training myself I knew this was coming. So I've been training myself to actually not touch my face as much as possible and it takes a lot of like discipline to get used to it. You don't often notice that you're doing it, but with time and just watching one noticing what you're doing, you can actually reduce your dependence on touching your face.

that sort of nervous habit of having a scratch or a rub or something like that. So yeah, I'll be practicing that for last couple months and it's been paying the results. Doesn't mean I'm not going to get this thing. but anyway, you know I got two kids and a wife and yeah, go to the gym and all sorts of stuff.

So mm-hmm it's not good. could pick it up anywhere, who knows. But anyway, at least disinfect service and this is great for like spraying on your keyboard and your mouse. You should be doing this daily.

like just get a 70% isopropyl. make sure spray it on your keyboard and your mouse cuz that's where like viruses and bacterias and things hit Love to hang out and like you can use it. you can spray buttons in the lift and things like that and you know all sides that like surfaces and handrails and all sorts of stuff. Not anything to help protect yourself but help protect our others as well.

Anyway, so what we're going to do is just put some isopropyl in here. This is just a smaller nozzle so let's put some in there like that right? So you want about 70% isopropyl like that and then you would just put in 30% water typically. Now that's great and it's very effective. Unfortunately, when you spray that on your hands, it does really dry out your hands very quickly because it evaporates and yet your hands and skin is just left like really dry and stuff like that.

So what? I've got here and this is totally optional and it adds absolutely no value to deactivating or denature in any viruses or bacteria. I've got some food grade glycerine here and this is using all sorts of Vo baking and their regionals, cosmetic and personal care and stuff like that. And it's basically a moisturizer. It effectively works as a moisturizer.

so if we whack, you know, maybe say fight. You know a few percent 5 percent you don't need much, so this is a bit gloopy like that, so just add some of that in and that will help and I'll just whack some water and this go over the top. So there you go. I've added some water, whack that in there and the glycerin stay on the bottom like that, but you want to just give it a good shake.

ER Like that, and Bob's your uncle. We've got ourselves some nice disinfectant spray for our fingers and surfaces and keyboards and handrails. Whatever you're touching and that is much better. I Can this is not feel a vision? but trust me that your hands feel a little bit more moisturized and less dried out with the glycerin.

But as I said, it's optional. We've just used like a 70% isopropyl in the past. So anyway, there you go. That's how you can make your own hand spray.

Don't go out in the supermarket and fight for it because it's exactly the same stuff. I Mean there is other types of disinfectants out there, but the most effective against these lipid viruses like Corona virus and herpes and influenza and hepatitis? B and all those sorts of stuffs is at least 70% isopropyl alcohol, but it typically comes in like that. This is 99.8% so you can't actually buy it already pre-mixed at 70% if you want to do that. No workers, but everyone's got water so like yeah, feel free to just buy the hundred percent stuff and this is great for cleaning your PCBs so yeah! I Highly recommend picking out.

You should have like at least a liter of this in your lab at any one time. I always kept like at least a liter here. just do I clean that PCBs and other things so it's great stuff. and I love the MIDI swabs.

you've seen me use these in many, many videos because they come with a little cloth thing in there and you know it's great for wiping off like heat sink compound and just generally I like cleaning up and be the second hangar you get on eBay or something like that so they're really handy. I Recommend. Like you can buy like boxes of those for fairly cheap. I Don't know what the prices are these days.

People are price gouging stuff these days like absolutely crazy. Let's not mention the dunny rolls shall we? And no, this is definitely not a substitute for soap and washing your hands. And soap actually deactivates or denatures the virus the outer protein shells in the same way that alcohol does basically, but yet this is not a substitute for that. But hey, when you're out and about, you can't like carry soap and have running water and stuff like that.

So yeah, the most effective method of course, is to wash your hands thoroughly with you know, 20 seconds. and even in my lab here my office building here. they've now got signs up there on how to wash your hands in the bathroom so they're everywhere. And yeah, this is going to be really good at long term.

People are going to be hopefully more vigilant about this sort of stuff during our flu seasons and things like that. So yeah, we've only just come out of summer here, so maybe that's helping him because heat does actually have an effect on the outer our protein shells as well. So there you go. I Hope you learn something there and I recommend you go out and just make your own disinfectant spray.

It's just. it really is quite nice and you get into the habit of like using this every time you touch something before you. especially before you eat. and things like that.

especially when you've got kids. You know, once we started having the kids. Yeah, the little petri dish, breeding grounds of bacteria and viruses that kids are. Yeah, like we're always spray in their hands every time.

like they come back from the playground before they eat and things like that. So we're all I'm always carrying one of these in my pocket and when I go to a restaurant before I eat or something, we just spray it on our hands and we've been doing this for donkey's years. So it's not just the mass hysteria here. but anyway.

I hope you found that useful. If you did, please give it a big thumbs up. As always discussed down below and check out my channel and subscribe over on a library you can go to eevblog TV or over just search library TV for eevblog I'm like number five in the world with a bullet. Catch you next time.
