CoronaVirus ==> Empty Shelves

[BobL]

eBay - if you can find any. I believe they are selling out FAST,
A few years ago I was given 40L of IPA but ended up giving more than half away so have hardly any left!
***** IMPORTANT*****
DO NOT USE ANY OLD STUFF FROM EBAY , HARDWARE, OR ELSEWHERE.
The safest stuff to use is pharmaceutical or food grade chemicals.
other grades may contain dangerous additives.
this may be ok for rhino hide tradie hands but could be nasty on kids or seniors.
You’d have to weigh this up against the risk of COVID19 😀

Hydrogen Peroxide 6% and Glycerol 98% came from the pharmacy. My local only had one large bottle of 3% until next week so I just used some of my current bottle of 6%, and 100ml bottle of Glycerol was around $6. The H2o2 at 6% is about $13 for 400ml (and 3% is about $11!)

Strong language in this clip,
But some very good points,

Some of you will be aware of my opinion of Scotty.

Cheers Matt.

Bear in mind that 400ml of 6% Peroxide will make 20 litres of Sanitiser, and 100ml bottle of Glycerol will make 6½ litres, so a small bottle of 3% peroxide would probably do most people. I insist on the 400ml 6% for my use as a mouth wash (which is also a VERY good thing to do help avoid C19, btw - apparently it kills the virus in the mouth before it gets to the trachea, and it also freshens up your breath brilliantly)

I think you will find pure Ethanol hard to get. Pharmacies are not allowed to resell it as they get it duty free for use in prescriptions and are only allowed a certain quantity in a certain time.

I use 10% H2O2 for metal bluing - its mixed with salt and applied to steel, rusting it before your eyes, then boiled in distilled water - this process is repeated as many times as you can stand.
Here's a before and after 6 passes of the above.

I don't reckon it's as good as Cold Acid fume bluing but the H2O2 method is much faster.

Anyway the H2O2 is food grade from beau - it was about $30 for 1L when I bought it last year.

Isopropyl alcohol is readily available but everyone on on ebay has jacked up their prices to STUPID levels.

At bunnings it's about $27 for half a litre!

I see Shame Warne is moving some of his his Gin distillery over to making hand sanitiser.
Maybe we finally find out about the key to his bowling?

Industrial quantities and specialist chemicals can be purchased from Solvent Chem Suppliers - Buy Solvents Online | Sydney Solvents

Unsurprisingly they are sold out, but I do know they are getting epic amounts of Ethanol in.

I buy (bought!) all my stuff from there.

Glycerol from the chemist, woolworths or any cake decorating place. Also try the car paint stores. Glycerol is used by airbrush people to add shine and smoothness to paints.... same with cakes

Hydrogen peroxide from Woolworths is sold in cleaning and the hair dye aisles.

Interestingly, the other mega-thread on the environment I've mentioned ethanol recently. I just happened to buy a bag of wheat flour from Manildra Group and they make it from waste products

Guess there will be more investment in Ethanol production soon

Go environment!


Edit - this is what I normally buy. Its 99% Eth, it is normally $35 - BioEthanol 5 Litre | Sydney Solvents

Tried to buy some Hand sanitiser today - like rocking horse *&$#
I have half a litre of iso propyl alcohol left over after the last operation Came across a similar recipe that uses Aloe Vera gel in the place of glycerol.
Thanks for the recipe

Only 96% required Tom because we are aiming for 80% ethanol in the final solution (96% of 833mls is 800mls). I think Industrial Meths is nearly 100% though isn't it? Ubeaut would know!

I don't think he usually bowled when he was p!ssed.

Well bugger me - I'd never have thought...

EDIT: Well at $4 for 200ml of 3% you are actually a little better off getting the $13/400ml/6% from the pharmacy, but only if you will use it all of course.

Your calculations are correct although 70% was always considered to be best strength as a disinfectant/cleanser.
The alcohol - Ethanol - supplied to pharmacies is either 90% (SVR -short for Spirit Vini Rect = rectified spirits of wine) or 95%. Methylated Spirits should contain Methanol. The odour that it has was added originally to stop the plonkos from drinking it and poisoning themselves as Metho was cheaper than grog.
Isopropyl Alcohol is used as a rubbing alcohol so should be OK in a hand sanitiser

Came across a similar recipe that uses Aloe Vera gel in the place of glycerol.

It's the gel that brings in the only use it three times a day rule apparently. They reckon that stuff gets trapped between the layers of the gel.....but if the gel don't kill that "stuff" then what's the 'king point of it anyway.

It's a bit like WHO saying you must have sterile bottles to put the sanitiser in.
EH?
If the sanitiser isn't going to kill what slight lergies MIGHT be in the bottle after washing, then I wouldn't be too confident about it killing what it is supposed to on my hands.....

Because most people will have access to a 1g balance rather than 1mL measuring volumetric cylinders, here is the recipe for 1 litre of hand sanitiser using 99 or 100% IPA by weight

	To make 1 litre
920	g IPA 99 or 100%
63	mls H2O2 3%
17	mls Glycerol 98%
1000	TOTAL

It won't matter if you are +/- a few mLs out with the last 2 ingredients, or +/- 20 with the IPA.
