Not really a recipe in the sense of what I normally post here, but it seemed like the best place to file it all the same.
Hand sanitiser is currently sold out pretty much everywhere, however we've people in the family who might be especially vulnerable to COVID-19 so need to minimise the chances of us contracting and communicating on.
So, as I keep some Isopropyl around anyway, I decided to make my own. The consistency isn't quite the same as shop-bought - it's a little more runny.
The recipe also uses some tea-tree essential oil, as it's supposed to have anti-bacterial and anti-septic effects. Unfortunately I can't stand the smell of the stuff, so I added a few drops of lime essential oil to help mask it a bit.
The measures below will create about 60ml (give or take depending on the essential oil), you should increase proportionally if you need more - to be effective the alcohol content must be at least 60%, the measures given will create a 64% concentration (assuming your total essential oil addition weighs in at 1ml, which is perhaps over generous).
You need 99.9% Isopropyl for this, using 70% won't work as you'll water it down below that important 60% mark. You can, however, dehydrate 70% Isopropyl (or even 50%) to get near-pure alcohol.
