make your own hand sanitizer
you mean make your own pointless smelly liquid that will not sanitise anything. Guff like this belongs on the pages of "Take A Break"
100 ml glass spray bottle
60ml witch hazel (sold in Tesco pharmacy for around £2 per bottle)
15 drops lemongrass essential oil (Ebay)
15 drops lavender essential oil (Ebay)
1 teaspoon vitamin E oil (optional (Ebay)
40 ml cooled boiled water
This is a good way to die. None of those ingredients are active against viruses.
70/30 ethanol followed by moisturizer if you can't get alcohol based hand sanitizer.

More out of idle curiosity than anything but is there any evidence that is effective in killing* the virus.
*do you kill a virus given it probably isn't "alive" in the strict sense? Maybe de-activate or de-nature?

you might as well rub your hands with a crystal

Yes, if you believe Wiki and almost every other source on the internet (unless you have rabies):
alcohol-based hand sanitizer is more convenient compared to hand washing with soap and water in most situations in the healthcare setting.[3] It is generally more effective at killing microorganisms and better tolerated than soap and water.[5] Hand washing should still be carried out if contamination can be seen or following the use of the toilet.[6]
Hand sanitizer that contains at least 60 % alcohol or contains a "persistent antiseptic" should be used.[17][18] Alcohol rubs kill many different kinds of bacteria, including antibiotic resistant bacteria and TB bacteria. 90% alcohol rubs are highly flammable, but kill many kinds of viruses, including enveloped viruses such as the flu virus, the common cold virus, and HIV, though is notably ineffective against the rabies virus.[19][20][21]
90% alcohol rubs are more effective against viruses than most other forms of hand washing.[22] Isopropyl alcohol will kill 99.99 % or more of all non-spore forming bacteria in less than 30 seconds, both in the laboratory and on human skin
Unless you're washing your hands properly, doesn't matter what you use
There's a reason we spray everything down with 70/30 ethanol klericide in the labs....
Certain virsuses are resistant to 70/30 though and require 90-95 percent sprays, which is why we use multiple types of sanitizers.
bloody hell, looking at how many they've sold, they've made some serious profit there!! Kind of goes against the email I got from eBay yesterday saying that profiteering will not be tolerated and listings would be cancelled/accounts suspended...Buy some off eBay…
For example, for anyone that is vaguely interested, entertainingly it turns out that Mountain Dew is more effective against Rhinovirus than 70/30

Does it have to be stronger than 60% alcohol or will a weaker solution do?
I was thinking of buying a couple of litres of cheap Vodka and trying to put it through on expenses 🙂
If it has to be over 60, I'd have to be buying cask strength whisky or Absinthe!

My skin reacts quite badly to most hand sanitizers and liquid soaps. Looks like I best stock up on gloves even more than normal.
Still best to sanitize the gloves before you remove them or touch any door handles at home. If you really have to go that far.

Yes.
Buy IPA, it is anywhere up to 99% ethyl alcohol. Or meths, at 90% ethyl alcohol. Both available on fleabay. Both will kill anything nasty.
There's a reason the peasants used to drink small beer instead of water...

This is for use when out and about and you're not able to wash your hands with soap and water. In this case both of those essential oils have antibacterial properties. Ideal for carrying in your handbag/manbag/Camelbak etc.
And just to inform you, I gave up wimminz magazines decades ago.

I wonder how mountain Dew compares to 20/20, not sure about covid but that certainly seemed to be good for herpes simplex back in the day.
Methylated can be nasty stuff, with methanol added - which is highly toxic and not something you really want to be rubbing on your hands. Avoid.
And just for you rayban sweetie.
fair point
Coronavirus isn't bacteria.
An active ingredient that has only been shown to have antibacterial properties won't work on it.
"antibacterial properties", maybe obvious, but coronavirus not a bacteria. Any (non hokey) research conclusively showing it kills coronavirus? Great, until then, it's voodoo.
edit: beaten to it
rayban has a valid point...
IPA might be a good shout. Not as toxic as methanol. Available a thigh percentages without the duty of ethanol.
I've got alcohol gel in any case.
I'm going to go an stock up on E45 to sell on to all the dermatitis sufferers we'll have in a few weeks.
fair point
IPA is a good shout though if you're going down the ghetto hand sanitisation route, as it's less drying.
Anyway, what draw weight crossbow for fighting off half starved deranged Londoners? A 50lb hand crossbow (which I assume is quick to reload) or a 200lb monster that will put a bolt through a car door? 😀
Where have I said that it would protect against the coronavirus? This is ideal for, say, you're pushing a trolley with handles around the supermarket then putting goods on the conveyer belt, touching the card reader. Then you head to the petrol station, perhaps pick up a sarnie, then again touching the card reader when entering your pin.
Think how many times you're touching surfaces, door handles, lift buttons, card reader buttons etc where thousands of others have done the same. Some folk including wimminz don't wash their hands after using the loo, hell some people don't even know what basic hygiene is full stop.
So what would you suggest, you being a scientist and all?

This is a thread about coronavirus. Why would you post that without understanding that you're implying it's effective against Coronavirus? Let's assume that what you say now, is what you meant earlier, where's the data that shows that concoction is effective against bacteria? What is the required exposure time for your concoction for it to be effective?
I was supposed to be in NYC today and tomorrow and then on West Coast later this month. I had cancelled as I got the flu a couple of weeks ago almost to the day and a still weak as a kitten and coughing so decided that avoiding a plane was not a bad idea ! Now all non essential travel is cancelled both domestic and international, perfect, means I don't have to go to London - woo hoo! WFH is going well as means I can supervise builders, listen to Spotify and , erm, surf the net.
UK cases up 35 in a day to 85
Buy IPA, it is anywhere up to 99% ethyl alcohol. Or meths, at 90% ethyl alcohol.
IPA is propanol (the clue's in the name, Isopropyl alcohol or propan-2-ol to give it it's proper name).
Methylated can be nasty stuff, with methanol added – which is highly toxic and not something you really want to be rubbing on your hands. Avoid.
I don't think meths has significant* amounts of methanol in it anymore precisely because desperate people would still drink it, it's just an impure ethanol with bitrex and purple dye.
*i.e. it's not added, there's probably some, just like some contains quite a lot of hydrocarbons.
Not implying that and apologies for the confusion. Am seeing it as useful when out and about if soap and water isn't available as a means of minimising any passing on of germs. Appreciate that, for example, travelling on overcrowded tube trains is another ball game that's fraught with risks. Can certainly understand why people are wearing masks although they offer variable degrees of protection it would seem. Is this something that you would do or indeed what precautions do you take, think you're London based?
I suspect big national companies like my employer that rely on "cheap unskilled drones" to bring in the $$$$ won't give two hoots about changing their standard illness policy for COVID19 until an employee dies.
Having unusually phoned in on Monday due to my symptoms wasting my weekend off work (but nobody picking up phone so I left a jumbled message due to how bad I felt), not one manager has approached me at work over the past two days to discuss my symptoms, where I've ended up feeling worse during each shift than how I've felt each morning before reluctantly heading in.
If a postie comes down with the real deal and comes into work, not only will they risk contaminating their fellow ~100+ colleagues in that day, but they also risk infecting ~600+ addresses just on their own delivery each day.

I would use FFP3 facemask on the tube if I could actually get some for a sane price to 1) limit the spread of the disease if I was unknowingly asymptotic but infectious 2) stop myself from touching my face.
I believe they offer a limited amount of protection from coughed droplets - but this is spread through the eyes as well.
Every little helps.
The better home made one is (better in that it may actually work)
70% vodka
29% aloe vera
1% essential oils (it has to smell nice)
Still best to sanitize the gloves before you remove them or touch any door handles at home. If you really have to go that far.
True, much easier on my skin though. I often wear gloves when I'm working to keep oil etc off my hands (Fire Protection Systems), so not a great leap to put them on entering and leaving site rather than just when I start work.

70% vodka
I read you need about 60% alcohol content to make it effective.
70% vodka would make around 30% alcohol.
IPA is propanol
yes, oops, having a concurrent conversation at work on same topic = failure to multitask.
I read denatured ethyl alcohol is effective against more virus types than IPA but both are effective for coronavirus types.
Also read at 70% conc it is most effective for sanitising, but, IANA chemist (nos surprise).
A friend has just booked flights to finale for mid March. He says the trails will be quiet. Selfish knob or clever boy . YOU decide....
Is finale covered on the fco travel list, or, any other than the USA one? (to my haven't-bothered-to-look knowledge
, no)
"clever"? No. selfish? No.
Just carrying on as normal. If anything, given the impact on tourism I'd imagine local people will be glad to see him so possibly community spirited.
If it does turn up on the list and he doesn't cancel, yeah, selfish.
Is there a UK map showing current case locations?
If you really must do ghetto hand sanitizer here are the WHO formulations for in field production
And here is a document/SOP that covers proper hand washing technique, this is probably the single most useful thing you can read if you’re non healthcare personnel. It’s simple, requires little extra effort and zero cost and will actually help.
My uncle and his partner set sail from Southampton yesterday for a nice cruise around the med. Think I will be giving them a wide berth for a few weeks when they get back
Certain virsuses are resistant to 70/30
Would it be more effective if you took some internally? Say at maybe 40%?
Only Wife's off shopping and if she cant get any hand stuff, I was thinking of suggesting a compromise alternative.
Edit. Ah. Apologies. Bin Dun.
So I was chatting to a guy at the weekend who it turns out he was just back from Iran... he had been (I assume since this was "work" related) tested, but does this show up pre-symptoms in the tests? He had only been back a week or so.
Should I raise my worry level from meh to hmmm?
Am I going to die from the bad kind of cat aids?
Should I go and hug as many members of the Tory Party as possible just on the off chance???

I would say copious amounts of booze is absolutely necessary if you feel fine but have to be locked up for two weeks. 🙂
