How to Make Liquid Soap - Recipe #1

Castile soap is a "generic" term used to describe a type of soap that is made using vegetable oil, typically olive oil, instead of animal fats. You can buy castile soap or make your own at home from scratch.


  • ½ cup grated castle soap, firmly packed (about one 4 oz bar)
  • 1 tablespoon vegetable glycerin
  • 2 cups water

Combine the water and soap in a pot over low heat. Stir until the soap has dissolved completely. Then, add the glycerin.

Pour into clean containers and close.

The consistency of this recipe may be thicker than what you would like for liquid soap. If so, add more water.

In the meantime, use it for bubble baths or as part of a natural shampoo.

How to Make Liquid Soap - Recipe #2

When you make this liquid soap, don't use a soap that is loaded with perfume. In fact, the less perfume, the better.


  • 1 6 oz bar of soap
  • 1 teaspoon of glycerin
  • 1 tablespoon of honey
  • Water as directed

Boil 1 cup of water.

While the water comes to a boil, finish grating the bar of soap. Then, pour the grated soap into your blender.

Add the boiling water. Put the lid on your blender and "whip it."

Stir in ½ cup of tap water. Then add the glycerin and stir, followed by the honey. After combining everything together, let the mixture sit for 15 minutes.

Whip it.

Add enough water to reach about 5 ½ cups. As you experiment with this recipe, you may want to add a little more or a little less water, depending on your preferences.

Whip it again.

Pour into clean containers, leaving the containers open so that the liquid cools.

After about an hour, add the lids.

Don't worry. The liquid thickens. Just remember to shake the bottle before you use the soap.
