The corona virus outbreak has caused sales of hand sanitizer to skyrocket. Hand sanitizer is flying off store shelves in in most shops and pharmacies as individuals and businesses stock up on supplies to protect them against corona virus infection. While the Centers for Disease Control and Prevention (CDC) maintain that the absolute best way to protect yourself is to frequently wash your hands for at least 20 seconds; and before eating, after using the bathroom, and after sneezing or coughing a second-best option is to use hand sanitizer with at least 60% alcohol, especially when you’re not near soap and running water.

What Ingredients do you need for Homemade Hand Sanitizer?

Recipes differ slightly for example, some recommend adding a scented oil while others keep that step optional. Here is WHO approved hand sanitizer instructions you can follow:

Ingredients

  • Isopropyl alcohol 99.8% — 7515 ml
  • Hydrogen peroxide 3% — 417 ml
  • Glycerol 98% — 145 ml
  • Sterile distilled or boiled cold water

Tools

  1. 10-litre glass or plastic bottles with screw-threaded stoppers, OR
  2. 50-litre plastic tank, translucent to see liquid level, OR
  3. Stainless steel tanks with 80-100-litre capacity
  4. Wooden, metal, or plastic spoon for mixing
  5. Measuring cylinders and jugs
  6. Plastic or metal funnel
  7. 100 ml plastic bottles with leak-proof tops, OR
  8. 500 ml glass or plastic bottles with screw tops
  9. An alcohol meter: the temperature scale is at the bottom and the ethanol concentration (percentage v/v) at the top

Directions

1. Pour the alcohol into the large bottle or tank

2. Add hydrogen peroxide using the measuring cylinder

3.   Add glycerol with 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 or tank

4. Top up the bottle or tank to the 10-litre mark with sterile distilled or cold boiled water

5. Place the lid on as quickly as possible to prevent evaporation

6. Mix the solution gently

7.  Immediately divide up the solution into the small bottles, and place them in quarantine for 72 hours. This allows any spores present in the alcohol or bottles to be destroyed

Final concentrations

  • Isopropyl alcohol 75% (v/v)
  • Glycerol 1.45% (v/v)
  • Hydrogen peroxide 0.125% (v/v)

Quality control

  • Always perform quality control on homemade sanitizer
  • Verify the alcohol concentration with the alcoholmeter. Make any necessary adjustments in volume to obtain the final recommended concentration
  • The accepted limits should be around 77% on the alcoholmeter, plus or minus 1%, at 25 degrees Celsius.

Store mixture in a cool and dry place and keep out of the reach of children.

Warning!

Note: Experts warns  that making homemade hand sanitizer is harder than it seems. If you don’t get the concentration right, experts warn that you’ll end up with something that isn’t effective or is too harsh, and is a waste of ingredients. The key is to get the right ratio of ingredients. The CDC Control recommends using a hand sanitizer that contains at least 60% alcohol, which store-bought hand sanitizers have.

Please do not go to the kitchen or near the flame, immediately after the use of hand sanitizer.
It contains spirit in rich quantity, and therefore is flammable.
