Quite a lot of people prefer using liquid hand soap to a bar soap. Somehow, it feels nicer. Besides, you don’t get that unappealing goo you sometimes get on a bar of soap—which can be quite a turn off when more than one person shares the bar of soap. When you use liquid hand soap, you know for a fact that what you use will come into contact only with your body not anybody else’s.

You don’t have to buy them, however. If you tend to have several small bars of soap of the same brand as leftovers, you can make your own liquid hand soap. You can even use brand new bars of soap if you want.

1. Gather the ingredients. You will need a single cup (250 ml) of soap flakes (or at first just a bar of soap), 10 cups (2.5 liters) of water (preferably bottled), and at least one tablespoon of glycerin.

2. Get your equipment ready. You’ll need:

  • A cheese grater
  • Measuring cups and spoons
  • A jar for your excess soap flakes
  • A big pot
  • A spatula
  • A funnel
  • A soap container with a hand pump for the finished product, along with other containers for the excess.
  • Optional ingredients include a face mask and some essential oils.

3. Use your cheese grater to grate the soap. It won’t be quite as easy as grating cheese though. You may also have some soap particles floating in the air while you grate, so you may want to wear a face mask to avoid breathing in the soap flakes. If you do this right, the soap will end up looking like you’ve grated some Parmesan cheese.

4. You’ll need only a single cup of soap flakes, so put the excess in a jar or small container. You can use these flakes for the next time, although that may be quite a while.

5. Mix your soap flakes with the 10 cups of water along with the tablespoon of glycerin. Put it on medium low heat and stir the mixture with your spatula. Wait until the soap flakes dissolve completely, but this should only take about a couple of minutes.

6. If it is too watery, you still have some options. It’s just that some bars of soap react differently to this process. You may want to wait for a few hours for the mixture to set and turn into gel—in one case the wait was 7 hours long! You may also opt to add more soap flakes and another tablespoon of glycerin to the mix. Others have also tried to use an electric mixer for better results.

7. Let it cool completely then use the funnel when you pour your liquid hand soap into your soap container. This recipe will result in a greater amount of liquid hand soap that will fit in a single container. You may want to put the rest in other containers.

That’s it—you’re done! You can also use it as body wash, and you can put in a couple of drops of essential oil to make it smell even nicer. Finally, if you are truly pleased with the results, you can even put your own fancy label on the liquid hand soap container saying the best liquid hand soap.
