Why Make Liquid Soap from Bar Soap?

Before we dive into the process, let’s explore the reasons why you might want to convert your bar soap into a liquid form. There are several advantages to making this switch:

  • Extended Use: Liquid soap lasts longer compared to bar soap because it is frequently simpler to use in specific circumstances, such as with pump dispensers.
  • Reduced Waste: Turning bar soap into liquid soap allows you to use up all of your soap scraps, reducing waste.
  • Customization: You can make your liquid soap how you want it to smell and feel because you have control over these aspects.
  • Cost-Effective: Creating liquid soap from bar soap instead of buying it from a store can save you money.
  • Eco-friendly: This method promotes sustainability by reducing the need for new plastic packaging and containers.

Materials You’ll Need

Before you get started, gather the following materials and ingredients:

  • Bar Soap: Choose a high-quality bar soap that you enjoy using.
  • Water: You’ll need water for dilution.
  • Glycerin: Enhances the quality of your liquid soap
  • A grater is used to grate the bar soap.
  • A Pot: For heating and mixing.
  • A Whisk or Spoon: For stirring.
  • A Soap dispenser is used to store your homemade liquid soap.
  • Essential Oils (optional): Some essential oils, like tea tree oil and lavender oil, have natural antimicrobial properties. Adding a few drops of these oils to your soap can help preserve it and provide a pleasant fragrance.

  • Step 1: Grate the Bar Soap

Start by grating the bar soap using a cheese grater or any grater with fine holes. This will make it easier to dissolve the soap in water. Aim for a fine, uniform texture.

  • Step 2: Boil Water

In a pot, heat a specific amount of water. The quantity of water you use depends on the thickness you want for your liquid soap. For a typical consistency, use about one cup of grated soap for every four cups of water.

  • Step 3: Mix the Soap and Water

Once the water is boiling, gradually add the grated soap while stirring continuously. Reduce the heat to low and keep stirring until all the soap has dissolved. This process might take some time, so be patient.

  • Step 4: Cool and Stir

After the soap has fully dissolved, remove the pot from the heat and let the mixture cool. It will thicken as it cools. Stir it occasionally to ensure an even texture.

  • Step 5: Customize with Essential Oils (Optional)

If you want to add a pleasant fragrance to your liquid soap, now is the time to do it. Add a few drops of your favorite essential oil and stir well. Popular choices include lavender, tea tree, or citrus oils.

  • Step 6: Transfer to a Dispenser

Once your liquid soap has cooled and reached your desired consistency, transfer it to a soap dispenser. Make sure the dispenser is clean and dry before pouring in the liquid soap.

  • Step 7: Use and Store

Your homemade liquid soap is now ready for use. It’s ideal for handwashing, body washing, or even as a mild dish soap. Store any excess liquid soap in a cool, dark place, and remember to shake it before each use to ensure even distribution.
