DIY Homemade Hand Sanitizer Formula from WHO — Updated



Do-it-yourself hand sanitizer formula from World Health Organization (WHO) scaled down for home use. US & metric recipes — click “SHOW MORE” below

Due to the Coronavirus (COVID-19) outbreak, hand sanitizers are in short supply. You can easily make your own using alcohol, hydrogen peroxide, and glycerin. The formula is recommended by the patient safety pamphlet “Guide to Local Production: WHO-recommended Handrub Formulations” at https://www.who.int/gpsc/5may/Guide_to_Local_Production.pdf

When you can, use ordinary soap and water to clean your hands. Use hand sanitizer only when soap and water are not available. https://www.cdc.gov/handwashing/when-how-handwashing.html

To help prevent shortages, please buy only the amounts of ingredients you will actually use in the next month. If everyone behaves reasonably, supplies will return to normal.

US units — to make one-third quart of hand sanitizer:

o 1 cup isopropyl alcohol 99% (see below for 91% or 70% alcohol)

o 1 Tablespoon hydrogen peroxide 3%

o 1 teaspoon glycerin

o Water to make a total of 1 and 1/3 cups (1/3 quart)

Metric units — to make 320 ml of hand sanitizer:

o 240 ml isopropyl alcohol 99% (see below for 91% or 70% alcohol)

o 15 ml hydrogen peroxide 3%

o 5 ml glycerin

o Water to make a total of 320 ml

Here is the procedure:

1. Put on glasses or goggles for eye protection.

2. Combine the first three ingredients in a container.

3. Add clean water to reach a total of 1 and 1/3 cups (320 ml).

4. Mix thoroughly by stirring or shaking.

5. Pour the mixture into dispensing bottles.

6. Label each bottle “Hand Sanitizer 75% alcohol”

Warning: For fire safety information, see the WHO pamphlet: https://www.who.int/gpsc/5may/Guide_to_Local_Production.pdf

Isopropyl alcohol (also known as rubbing alcohol) is the ingredient that kills bacteria and viruses. It is sold in different strengths, typically 70%, 91%, and 99%. The target strength for the final hand sanitizer is 75% alcohol.

o For 99% alcohol, start with 1 cup (240 ml)

o For 91% alcohol, start with 1 cup plus 4 teaspoons (265 ml)

o For 70% alcohol, start with 1 and 1/4 cups (300 ml)

The 70% alcohol case, no additional water is needed, and the resulting sanitizer is 66% alcohol, which is less than the WHO recommended 75%, but still greater than the minimum required 60% for effectiveness.

Do not use 99% alcohol directly as hand sanitizer. Some water is needed with the alcohol to work. The hand sanitizer must be between 60% and 95% alcohol. https://www.cdc.gov/mmwr/PDF/rr/rr5116.pdf

Hydrogen peroxide 3% is an antiseptic sold in drugstores with other disinfectants. The small amount used in the formula is not effective for sanitizing the skin. Its purpose to kill any spores in the ingredients and containers.

Glycerin (also known as glycerol) is a clear, thick liquid used as a moisturizer in skin care products and as a food ingredient. It helps prevent your hands from drying out. You can find it in the drugstore with other skin care products.

If your water is not absolutely clean, first boil it and allow it too cool to room temperature. If your containers and ingredients are not absolutely clean, allow 72 hours for the hydrogen peroxide to kill any spores present, and keep the solution away from sunlight and UV light, which break down the hydrogen peroxide.

Some viewers are asking if they can substitute, omit, or add specific ingredients. Sorry, I don’t know. I just took the WHO formula and scaled down the quantities. The WHO pamphlet recommends not to add any fragrance or gelling agents.

The consistency of the final product is a liquid, not a gel. A spray bottle is useful for applying the sanitizer to your hands without dripping. Be careful to direct the spray at your hands. Label the container and keep it away from anyone who might misuse it.

Beware of DIY hand sanitizer formulas that result in a final alcohol content of less than 60%. For example, mixing two parts 70% alcohol with one part aloe vera gel results in a final 47% alcohol content, which is too low. 80-proof vodka is only 40% alcohol and therefore not suitable for making sanitizer.

  15. I read the label of a hand sanitizer bottle. It said it kill germs and bacteria. It said nothing about viruses.

  16. Your trick doesn't work there's no more alcohol in every stores i went to ! some are selling a quart online for 90$ not a store i seen is restocking supplies are all out !

  17. The virus is made in China. You know it is going to break in a couple months.

  18. H2O2 breaks down when exposed to light. Use a dark spray bottle.

  19. Why not just use the alcohol alone?

  20. What is the best brand to get pure glycerin product

  21. You should have rubbed it on the top of your hands as well. To be effective you need to use enough so that your hand stay wet and do not dry them off.

  22. Unfortunately, isopropyl alcohol and hydrogen peroxide are very difficult to come by during this crisis.

  23. The best sanitization is water and soap

  24. People used to laugh at me or look at me strange because I use paper towels to open restrooms doors and always over wash my hands and hand sanitizers I carry around with me all the time now all of a sudden it's not funny I feel sorry for ignorant people they are the ones that should look in the mirror at themselves in wonder

  25. Now all of a sudden people want to be clean WOW it is so sad and true that it seems like it always takes a tragic to wake people up to come to realize

  26. He's not making sanitizer he's making a bomb Lol

  27. Oh just wonderful as these are more answer that deal with ingredients that NO ONE CAN GET so this is worthless. I've tried to get two of these now for over a month and they tell me all the hospitals are getting the peroxide and alcohol.

  28. Increase glycerin or aloe? It seems very runny.

  29. What's on 2nd & I Don't Know is on 3rd.

  30. First teach them how to distil alcohol the main ingredient of the sanitiser. Rubbing alcohol is equally scarce.
