How To Make Your Own Hand Sanitiser

How to make your own hand sanitiser.

Ask almost any healthcare professional what the best thing you can do to protect yourself from disease and the first answer they will give is to wash your hands. Those biological marvels, wth dextrous fingers and opposable thumbs might be a massive evolutionary advantage for Homo Sapiens but they're also great at collecting and spreading microbial nasties.

While washing your hands is important it can be a pain to do after every sneeze or cough. Which is why hand sanitiser is so handy. A quick squirt and a rub and most of the risk of infection is gone. But hand sanitiser can be expensive and hard to come by. Here's how to make your own hand sanitiser.

With the outbreak of coronavirus leading to panic being in some locations, hand sanitiser might end up being in short supply, especially if supply chains are compromised. many Amazon sellers are already out of stock. But it turns out that making hand sanitiser is straightforward. There are just two ingredients and both are pretty easy to come by.

This recipe from ThoughtCo lays it all out.

The two key ingredients are isopropyl alcohol (also known as rubbing alcohol) and aloe vera gel. Combine two-thirds of a cup of the rubbing alcohol with one-third of a cup of the gel and you're done.

Throw in some essential oil of your preferred scent if you like, mix them all up and decant the mixture into a suitable dispenser and you're done. The creators of this recipe note that essential oils such as thyme and clove oil have antimicrobial properties so make good candidates for the recipe.

While keeping your hands clean is a good thing to do, wiping down your smartphone with alcoholic wipes is also a good idea, particularly if you've shared it.

    Or just buy some good old isopropyl alcohol from the chemist... or even better spray vodka on your hands

    The best advice is not to make your own. It must be at least 60% alcohol to be effective. Isopropyl alcohol is in short supply industrially in Australia (no doubt elsewhere) at the moment because the supply is being directed towards the production of sanitiser.

    Just alcohol will dry your hands out very quickly, that's why it has the moisturiser. Dry (abd cracked) skin will not be very good outcome.

    A quick squirt and a rub will not do the trick. It needs to be quite a bit if you want it to be effective.

    You are better off using soap and water until you can buy the commercial stuff at the chemist.

    Even better don't touch things. A letter to The New England Journal of Medicine from researchers at the CDC detailing results from some research they have been conducting. They simulated a sneeze onto various surfaces and there was viable amounts of SARS-CoV2 after

    4hrs on copper,
    24hrs on cardboard,
    48hrs on stainless steel, and
    72hrs on plastic.
    In the air it lasted at least 3 hours, because 3 hrs was the limit of that particular test. Here is the link https://www.nejm.org/doi/full/10.1056/NEJMc2004973?query=featured_home

    WHO recommends *at least* 75% isopropyl alcohol.
    And good luck sourcing Aloe Vera gel.

      You could extract it from hand sanitiser by heating it.

    And now Isopropyl Alcohol has been bitten by the price gouging parasite.

    In January a 5L of 70% was about $15 on Amazon and now its up near $300.
