We are going to explain how to produce hand sanitizer at home this method is recommended by WHO, for more information such as control the quality or how to store them

Ingredients for the production of hand sanitizer;
1- Ethanol 96%
2- Hydrogen peroxide 3%
(Hydrogen peroxide: used to inactivate contaminating bacterial spores in the solution and is not an active substance for hand antisepsis.)
3- Glycerol 98%
(Glycerol: used as a humectant, but other emollients may be used for skincare, provided that they are cheap, widely available and miscible in water and alcohol and do not add to toxicity, or promote allergy.)
4- Sterile distilled or boiled cold water
Any further additive should be clearly labelled and be non-toxic in case of accidental ingestion.
A colourant may be added to allow differentiation from other fluids, but should not add to toxicity, promote allergy, or interfere with antimicrobial properties. The addition of perfumes or dyes is not recommended due to the risk of allergic reactions.
5- 10-litre glass or plastic bottles with screw-threaded stoppers or
50-litre plastic tanks (preferably in polypropylene or high density polyethylene, translucent so as to see the liquid level)
6- Wooden, plastic or metal paddles for mixing
7- Measuring cylinders and measuring jugs
8- 100 ml plastic bottles with leak-proof tops or 500 ml glass or plastic bottles with screw tops, for store them.
Recommended amounts of products:
1- Ethanol 96%: 8333 ml.
2- Hydrogen peroxide 3%: 417 ml.
3- Glycerol 98%: 145 ml.
Step by step preparation:
1- The alcohol for the formula to be used is poured into the large bottle or tank up to the graduated mark.
2- Hydrogen peroxide is added using the measuring cylinder.
3- Glycerol is added using a measuring cylinder. As glycerol is very viscous and sticks to the wall of the measuring cylinder, it should be rinsed with some sterile distilled or cold boiled water and then emptied into the bottle/tank.
4- The bottle/tank is then topped up to the 10-litre mark with sterile distilled or cold boiled water.
5- The lid or the screw cap is placed on the tank/bottle as soon as possible after preparation, in order to prevent evaporation.
6- The solution is mixed by shaking gently where appropriate or by using a paddle.
7- Immediately divide up the solution into its final containers (e.g. 500 or 100 ml plastic bottles), and place the bottles in quarantine for 72 hours before use. This allows time for any spores present in the alcohol or the new/re-used bottles to be destroyed.
