Homemade Foaming Hand Sanitizer

Make your own foaming hand sanitizer. If you choose to use alcohol, make sure the sanitizer contains at least 60% alcohol in order to be effective. Many homemade recipes circulating on the web call for much less alcohol and this makes them ineffective as germ killers, according to an article in the New York Times. One benefit to making your own hand sanitizer is being able to customize it to your needs.

The Facts Behind Sanitizers

Hand sanitizers work effectively because of the alcohol content. The alcohol content needs to be at least 60% to be effective, unless you want to try an all-natural version using vinegar and lemon juice as the active ingredients. Hand sanitizers also need hands free of blood, dirt or other mess in order to be effective. If the hands are visibly dirty, they need to be washed first, then treated with hand sanitizer. Foaming hand sanitizers are convenient. The foaming mechanism is hard to duplicate at home. But by purchasing one bottle of anything in a foaming dispenser, you can use the bottle again and again. You will notice that you use much less sanitizer this way.

The Foam Dispenser

The actual foam dispenser is a great way for soap companies to sell less soap for more money. You will notice that if you are refilling your foaming soap dispenser, you must fill it with about one centimeter of soap and the rest of the bottle with water. Any more soap and the dispenser will not work properly. If you do not use your soap quickly enough, a slime will form, which will make the dispenser stop working. All commercial brands of liquid soap contain ingredients that make it foam.

The Recipe

To make your sanitizer work, you will need a foaming dispenser, a small amount of liquid soap, and alcohol. Fill your bottle with ½ centimeter (about 1/4 inch) liquid hand soap and fill the rest of the bottle with isopropyl alcohol. You may even need less soap. Foaming hand dispensers vary in how much soap is necessary, so experiment a bit.

A Natural Alternative

A study in the International Journal of Food Microbiology showed that lemon and vinegar were nearly as effective at reducing salmonella as alcohol. If you would like a natural alternative hand sanitizer, you could try filling your foam dispenser with a very small amount of liquid soap, with the rest of the bottle filled with a mixture of half lemon juice and half vinegar.
