It was sold out for a long time and people started auctioning them on ebay and they were sold for $500 easily.
its now back in stock, i dont know we may have a second wave. if people want to buy probably its a good time to have some to create your own hand sanitiser.
on their ebay store its $15 more expensive incl postage.
Are you sure you're not confusing it with methylated spirits?
Definitely 100% Isopropyl Alcohol. I bought some pre-covid19 in the $20-$30 range.
Fair enough
You are correct. I think I paid around $27 for this pre-covid.
Not 99% or 98%?
Getting that last few percent on a hydroscopic chemical is usually very expensive.
I usually find 99% at that price, but if its truly 100, thats a hell of a deal.
Metho is about 95% ethanol and 5% iso-propyl alcohol, according to the MSDS. So still a disinfectant and can also be used to make hand sanitiser to a WHO recipe.
Have you smelled metho before? A chemical (probably Pyridine) is added to discourage recreational use. It smells really bad. I definitely wouldn't want to use a hand sanitizer made from it.
@eug: I was too lazy to post before but different manufacturers have slightly different recipes for methylated spirits. Here's one that uses 5% propanol and 95% ethanol:
https://www.hanleysonline.com.au/sds/Solutions%20Methylated%20Spirits%20(SOL0051501)%20SDS.pdf
You can get 5L of hand-sanitiser already made in individual 1L bottles for $59.40 at Bunnings
Edit: Upon double checking, Bunnings have jacked their price up to $13.90 per 1L bottle.
Hand sanitiser uses ethanol, this is a different alcohol.
It was a response to op's statement:
if people want to buy probably its a good time to have some to create your own hand sanitiser.
I wasn't responding to you. My comment was in reply to Spludgey "Hand sanitiser uses ethanol, this is a different alcohol." Either ethanol or propanol can be used for hand sanitiser
No, post covid sanitiser uses ethanol. Prior they used either, or neither. But even the WHO recipe shows that isoprop alc is effective at 10% lower concentration levels than ethanol. That is, its more effective.
This was just unavailable.
it appears that grammar is no longer fashionable thats a shame but its inevitable
anyway im off to go help my uncle jack off a horse
Use both hands.
Let's eat grandma
How do you think they breed racing horses?
They sure do run fast when they see him.
I bout 5l for $10 delivered from this deal
https://www.ozbargain.com.au/node/387741
At the height of the covid panic 5 litres spiked to over $1000 on ebay.
Aye, same!
Still haven't opened it.
If you haven't opened it during a pandemic, I doubt you'll ever open it!
That deal was amazing, still have a bottle left. It gets used all the time, cleaning electronics, greasy furniture etc.
It's great because it doesn't leave residue as it's 99.9%.
Ever wondered what the other 0.01% consists of?!
Unicorn piss
Likely isoprop alc. Its just hard to state 100% reliably.
Its up there with kills 99.99% of germs, it likely kills 100% but its hard to state that and be reliably certain. Margin for error.
Really wish I knew of this deal. Been on the hunt for decent priced high percentage Isopropyl for restoring and cleaning electronics, but Covid has screwed that up for me.
That's hand santiser, not isopropyl alcohol.
It was a response to op's statement, that there is an easier and cheaper way to get hand sanitiser:
if people want to buy probably its a good time to have some to create your own hand sanitiser.
This is not hand sanitiser, it's pure liquid alcohol. You use this to clean hard surfaces. You'd dilute it to about 70% by adding distilled water, so you'll end up with 8.5L of 70% alcohol. 8.5L of the hand sanitiser you linked will cost $102.
Ingredients
Alcohol, aqua, PEG-40 hydrogenated castor oil, triethanolamine, acrylates/ c10 -30 alkyl acrylate cross polymer, fragrance. Contains 70% v/v Ethanol
I was referring to this deal.
If it was 100% pure alcohol and you diluted 500mL to 70%, then you would have 500/0.7 = 714mL.
Bunnings is $27.50 for 500ml so this is a good deal in comparison:

diggers is way overpriced
What a rip off. A year or so ago I bought similar product for $20 delivered
I'm pretty sure things are a little different to a year ago…..
Yep and Sydney Solvents took advantage of the supply shortage (I checked). Perhaps they had an excuse for the outrageous price, perhaps not.
Yep and Sydney Solvents took advantage of the supply shortage (I checked).
How did you check? Are you certain that Sydney Solvents took advantage of shortage, and not their suppliers? If their suppliers raised their prices, would you expect Sydney Solvents to sell each one at a large loss?
I checked SS' price on ebay, where I'd bought from them previously. My second sentence covers your last question. My guess is that there was a component of both (supply issues and taking advantage) involved.
My second sentence covers your last question.
Your first sentence says Sydney Solvents did take advantage of the shortage, and that you checked (i.e. confirmed) it.
Your second sentence said perhaps they had an excuse, perhaps not. That negates your first sentence because now you're not sure if they did take advantage of it or not, even though you said you checked.
So your first sentence is incorrect?
@eug: Not incorrect, but could have been better put. I meant SS took advantage in regards to extremely high prices - a reference to the OPs comment about "people" auctioning at outrageous (my word) prices.
Interestingly the hypocritical Dutton made a point of saying he'd come after "profiteers" with a big stick but I'm not aware of one case where he did so. His statement was simply puff as most knew, especially as "market forces" are the basis for most conservative economics.
Serious question: are lots of people using this over washing hands etc? 5L seems excessive for a family when you apply a small squirt if/when you use it.
I wanted to get some for window cleaning but prices at the moment are crazy
This isn't an appropriate hand sanitiser, it will dry out your skin very quickly.
It's incredibly useful for cleaning electronics, screens and technology related items (as it does not cause corrosion, nor conducts, evaporates without leaving marks and disinfects as it cleans).
If people don't need anything super pure as such (e.g. just cleaning your electronics like mounting a CPU cooler like I did in the past) just metho.
It doesn't go bad or expire.
at home i wash hands with soap as it also gets dirt off, keep alcohol in small spray bottle in car for when i’m out and about , 5L of a.cohol,goes a long way as a sanitizer.
This is too harsh for the skin. Rubbing alcohol that you can use for skin is 70%.
I paid $29 including delivery to Melbourne last November, from the same company. Use it as a glass cleaner and general purpose cleaner. Have 4l sitting in the container in my garage. Had no idea i could have sold it for that much.Dam missed out on a quick profit. But now $77 inc postage compared to $29 inc postage.
Thanks OP this will clean my glassware brilliantly.
At $29 delivered was cheaper than all glass cleaner products and worked great
I wouldn’t recommend getting this on your hands
Buy now, sell during second wave. Profit.
This is 100% pure alcohol. Hand sanitisers are "normally" kept at 75% alcohol max. So if you mix 750ml of this and 250ml of water (boil it first and let it cool) and add some aloevera you would have your own product. It will be somewhere around 6.6 litres.
I got the recipe from the internet :)
Hand Sanitiser: 3/4 cup Isopropyl Alcohol and 1/4 aloe vera gel
Boiling water is not good enough, you need distilled water.
Boiled water is good enough. You can keep it at a rolling boil for a minute to be sure. Don't forget you're also mixing that boiled water with pure alcohol which would disinfect it anyway.
Tap water contains heavy metals, what would alcohol disinfect that boiling wouldnt ? If you want pure water, the only way to get that is through distillation.
Tap water contains heavy metals
Tap water does not contain heavy metals in any appreciable amount - that is why tap water here is safe to drink.
If you want pure water, the only way to get that is through distillation.
The point is, the water does not have to be pure. We're not washing our hands with distilled water and soap after all.
@eug: Ideally distilled water should be used (it's cheap and readily available in stores). Either way, the water is added to make the alcohol suitable for a topical application. Too much absorption of isopropyl alcohol can be harmful to some people (eg https://pubmed.ncbi.nlm.nih.gov/10670080/ ) but the real point of dilution is because 70% works better for destroying pathogens:
"The presence of water is a crucial factor in destroying or inhibiting the growth of pathogenic microorganisms with isopropyl alcohol. Water acts as a catalyst and plays a key role in denaturing the proteins of vegetative cell membranes. 70% IPA solutions penetrate the cell wall more completely which permeates the entire cell, coagulates all proteins, and therefore the microorganism dies. Extra water content slows evaporation, therefore increasing surface contact time and enhancing effectiveness. Isopropyl alcohol concentrations over 91% coagulate proteins instantly. Consequently, a protective layer is created which protects other proteins from further coagulation…" (see: https://blog.gotopac.com/2017/05/15/why-is-70-isopropyl-alco…)
Ideally distilled water should be used.
Ideally yes, but using boiled water is fine. Heavy metals in Australian tap water is not a concern.
Either way, the water is added to make the alcohol suitable for a topical application.
Yes, that's what OP said.
@eug: "Either way, the water is added to make the alcohol suitable for a topical application."
Yes, that's what OP said.
Actually he/she didn't if your want to be pedantic, nor did he/she imply it - unless we are seeing different views.
@[Deactivated]: Are you looking at the same OP? I was referring to the OP of the comment I was replying to.
wrx5 says you can add this pure alcohol to boiled water and aloe and make your own hand sanitizer.
garetz replied saying boiled isn't good enough, it has to be distilled.
I replied saying boiled is good enough as boiling kills everything of concern.
garetz replied saying tap water contains heavy minerals.
I replied saying heavy minerals is not a concern in Australian tap water, and everyone is happily washing their hands with (and drinking) tap water anyway.
You then replied saying ideally distilled water should be used, and the water is added to make the alcohol suitable for application - which is what wrx5 said right at the start.
@eug: I looked at both. You're inferring something which wasn't there. It happens in forums like this.
You're inferring something which wasn't there.
You don't see the part where wrx5 describes adding water to the alcohol?
So if you mix 750ml of this and 250ml of water (boil it first and let it cool) and add some aloevera you would have your own product.
You then said
Either way, the water is added to make the alcohol suitable for a topical application.
The way I read it, OP said to make this into hand sanitiser, you have to add water (and aloe if you want a moisturiser) to it.
You said, the water is added to make it suitable to use as a hand sanitiser.
Aren't you both saying the same thing?
You did describe the reason why as well, but nobody was disputing that.
@eug: Appears you don't understand what is meant by topical application and hence the other part of the reason why the lower percentage is important. It's a different issue from effectiveness against pathogens. I gave you links above, there are plenty more.
Appears you don't understand what is meant by topical application
Topical application most commonly refers to applying a substance onto skin.
OP was talking about making hand sanitiser. That is a topical application of a substance.
What is your definition of topical application?
and hence the other part of the reason why the lower percentage is important.
OP gave a recipe for 75%, you said 70%. Are you just being pedantic over the 5% difference? Do you think the WHO's official formulation, which has a final concentration of 75% isopropyl alcohol, does not work?
@eug: You really are a dog looking for a bone eh? I've already explained that there are two considerations (ie more than 1, you understand that basic concept presumably?) when applying alcohol to the skin. Read what I wrote, read the links, and if you still don't understand phone a friend.
Oh and try not to use the childish straw-man argument technique in future:
Are you just being pedantic over the 5% difference? Do you think the WHO's official formulation, which has a final concentration of 75% isopropyl alcohol, does not work?
You really are a dog looking for a bone eh?
Do note that you are beating around the bush and refusing to actually explain what you meant.
I've already explained that there are two considerations (ie more than 1, you understand that basic concept presumably?)
There is no need to be condescending. You highlighted your point in bold - the 70% figure. The only other consideration is "Too much absorption of isopropyl alcohol can be harmful to some people". You provided a link to an abstract that had no details.
Oh and try not to use the childish straw-man argument technique in future:
Read what you wrote again.
OP gave a recipe for a 75% formulation. Someone mentioned distilled water should be used. I replied saying boiled water is fine. You replied, saying:
ideally distilled water should be used - yes, ideally it should be distilled water. But boiled water is safe.
the water is added to make the alcohol suitable for a topical application - I replied saying that's what the OP said - the recipe given involves adding water.
too much absorption can be harmful to some people - there is not much difference between 75% and 70%. The link to the abstract you provided provides no details.
the real point of dilution is because 70% works better for destroying pathogens - your source is a webpage from an online store. Once again, keep in mind this whole thread is talking about a 75% formulation - refer to the original post. I mentioned that the WHO's official formulation has the same concentration. What is your claim that 70% works better, based on? Or did you not read the original post and assumed everyone was talking about 100% IPA vs a diluted IPA solution?
@eug: Apparently your reading is okay but your comprehension is negligible. My posts - apart from the comment regarding Sydney Solvents, which I clarified - were simple enough for most junior secondary students to understand, yet multiple references to the same points haven't enough for you. There are numerous credible references to isopropyl alcohol usage on the web (including clinical studies) - as I told you. They cover both issues (ie more than the 1 you're obsessing about while ignoring the other). If you are actually interested in the topic (long bow) and not the "sound of you own voice" I suggest you have someone find a few of them and explain both the main issues in terms you can understand.
Alternatively keep re-reading my posts above, you might eventually find that bone. Here's a clue - the pubmed ref might clear your fog.
@[Deactivated]: Once again, there is no need to be condescending.
It does look like you made a mistake in assuming everyone was talking about 100% IPA when you joined the discussion and do not want to admit so, hence the beating around the bush constantly avoiding the question.
I shall leave it at that.
@eug: Your conclusion above is, once again, totally wrong. Did you find the bone, or did you yet again ignore the info in the links I provided originally? Jethro Tull was right.
@[Deactivated]: Once again you beat around the bush and avoid all the questions. That just reaffirms my conclusion. :)
@eug: I told you your conclusion was wrong (again). Wasn't that clear enough for you? The rest you can work out for yourself. Rather than expecting me to spoonfeed you I suggest you do some research for yourself. You might learn something you obviously didn't and still don't know about, despite my pretty obvious references above.
@[Deactivated]: The more you beat around the bush, avoid the questions, and resort to condescension, the more you reaffirm my conclusion.
Anyway, this clearly isn't going to go anywhere, so this time I'll really leave it at that. :)
@eug: There are no questions requiring answers. You created a straw man - ie attributed views to me which were totally unwarranted and expected me to respond to them. Childish rubbish. There is nothing complex about what I wrote, nor is there anything complex about isopropyl alcohol use on the skin - IF you bothered to inform yourself you'd understand the two important issues there, only one of which relates to virus destruction.
Theres plenty of water in most consumer aloe. I made mine with 80ish% electronics grade 99.9% isoprop alc, and the rest from a bottle of pure aloe gel.
Does urine sanitise hands?
Well no one is going to want to touch them, so that's one way to keep them sanitised.
Only if you drink it!
If you buy this and want to use it as disinfectant then dilute to 70% with distilled water. It has been proven to be more effective than 100% iso because it doesn't evaporate as fast and has more time to kill the nasties.
What was their price pre covid?
I paid $29 delivered to Melbourne
Neg coming. Cashing in on covid. Cheaper on ebay. $46.95 delivered
https://www.ebay.com.au/itm/min-99-8-pure-Isopropyl-Alcohol-…
"This seller is currently away, and isn't processing orders at this time. You can add this item to your watch list to purchase later. "
I suspect the price won't be $47 when they get back to processing orders. Or, you will be waiting 2-3 months for it to be delivered.
I didn't notice that.

Edit: $57.95 delivered with code EOFYHOT
What a bargain for all those meth labs!
Neg.. nothing about this is a bargain! Just because you are not overcharging like on eBay doesn't make this a good deal. It's still over and above pre C19 days. make it $30 inc PP and then we are talking!!
LOL. Seriously. The manufacturers can't keep up with demand. Law of supply and demand determines price in this case. If it is in stock and cheaper than other places you can get it NOW, then it is worth posting. Very hard to find this stuff in stock. Radioparts for example is still catching up on orders on 5L and 20L made in mid-March - that is, 3 months ago. I expect most resellers are in the same boat.
Still way higher than pre-covid19 prices. Was around $20-$30/5L pre-covid19
