3 Ways to Make Homemade Liquid Hand Soap


As mentioned earlier, this is a very beginner-friendly process. Follow through!

METHOD #1: How to make liquid hand soap with a soap base

Soap making with a soap base may be easier than making soap from scratch. However, the process is quite tiresome and time-consuming.

But compared to formulating liquid homemade hand soap by yourself, making soap with a soap base has fewer components because it has a base to begin with.

All you’ll need is the soap base, distilled water, added fragrance, and soap dye.

Making this type of liquid soap involves diluting the soap base and constantly stirring.

The issue is not the melting process itself but rather the amount of time it will take to monitor the melting process.

Diluting and heating the soap base with water may take several hours. But once the process is complete, you can enjoy the fruit of your labor.

Is this simple enough? Why don’t we make it easier!

METHOD #2: How to make liquid hand soap from a bar.

Making liquid hand soap from bar soap is arguably the easiest way to make soap. And as the name implies, it makes liquid soap from a soap bar.

The materials you will need to make liquid soap from bar soap are a soap bar and water. You can add fun ingredients such as fragranced essential oil and glycerin for hydrating properties.

Crafting this type of liquid soap involves chopping or grating the soap into smaller pieces and then melting the soap with water to liquefy the soap.

What to prepare to make your own liquid hand soap

  • Natural-made soap bars
  • Distilled water
  • Essential oil (scent of your choosing)
  • Glycerin
  • Knife or cheese grater
  • Wooden ladle
  • Pot
  • Measuring cups
  • Refillable bottle with pump

Detailed steps:

Step #1: Grate the bar of soap and heat the pot up.


  • Grab eight cups of water from the distilled water and pour it all into the pot. Let it boil with moderate to high heat.
  • While the water is heating, grab your cheese grater and soap. Then, start to grate your soap into shavings. You may also cut the soap into small pieces with a knife.

But we prefer grating the soap with a cheese grater, which makes the soap smaller. Thus, it is easier to melt when that time comes.

Of course, you may choose which soap bar you prefer. But natural-made soap bars give moisturizing properties to prevent skin from drying.

Step #2: Melt the grated soap in the boiled water.


If you’ve noticed that your water is done boiling, you can now start the melting process. Make sure that you have wholly grated the soap before beginning this process.

Gradually add the grated soap into the pot to prevent the soap from clumping. You can start with a few fingers full, then keep on placing more soap until you have put all of it into the pot with the water.

To ensure the bar soap is melting, stir the mixture from time to time. Keep on going until the soap and water have completely dissolved into each other

Step #3: Add the supplementary ingredients of your choosing.

Once the soap and water have entirely melted together, you can start adding additional ingredients.

Note that this recipe is without Castile, so you won’t need to add this ingredient.

  • Let’s start with glycerin.

Some recipes opt not to use this ingredient. But glycerin has many benefits. Some include making the soap mixture less lumpy, making the soap disintegrate faster, and hydrating the skin better.

  • You can then add a few drops of the essential oil, which, of course, is your chosen scent.

You can even make, for example, a homemade liquid hand soap coconut oil-scented!

The benefits of adding essential oil as a fragrance are its moisturizing properties. It is entirely natural, therefore eco-friendly, and has a scented aroma.

Step #4: Finishing steps for the process.


After adding the glycerin and scented essential oil of your choice into the hot mixture, you can start the cooling down process.

  • Set your whole mixture aside for about half a day, the entire day, or until it has completely cooled down.
  • Avoid mixing the liquid hand soap recipe while it is cooling down. The foam may form, and you want to avoid that as much as possible.

If you notice that the mixture is still quite lumpy and uneven, you can always repeat the heating process. You can do this by placing the pot on the stove once more and mixing until the texture is smoothened.

  • You may see fit to repeat this step until you have attained the preferred texture.
  • Once the soap has wholly cooled down and if you have accomplished the right consistency, you can start to transfer your DIY essential oil hand soap. Grab the refillable bottle you have set aside and slowly pour the liquid soap into the bottle with a pump.

And ta-da! Easy-peasy, right? Once you have completely mastered this technique of making liquid soap from bar soap, you can now attempt to try the other methods of making homemade liquid hand soap.

METHOD #3: How to make liquid hand soap from scratch.

Making liquid soap from scratch entails a particular product. This ingredient is called potassium hydroxide.

While sodium hydroxide is used for solid soap bar making, potassium hydroxide is utilized to give the soap the ability to liquify, especially when combined with water.

Ingredients you would need to make soap from scratch are:

  • A blend of different nourishing oils
  • An array of butter
  • Fragrance oils
  • Soap dyes
  • Potassium hydroxide

The procedure involves heating the ingredients and mixing them all together until they are cooled down for use.

However, what makes this method difficult is that the use of sodium hydroxide is a high-risk practice as it can be harmful when you’re exposed.

You may face several hazards, like eye damage or nose, throat, and lung irritation.

Given that, this DIY hand soap method is not for beginners at all! You may try this when you’ve already advanced to the more technical side of soap-making.


Although we have our preferences, there are many advantages to using liquid soap to which solid bars do not hold entitlement, especially if you develop a natural liquid soap.

Some benefits of liquid soaps include their neatness and convenience. Combine those with the properties of natural-made soaps, and you’re golden!

Now that you know how to do this process, you can quickly practice and create DIY homemade liquid hand soap. There is no harm in trying other DIY liquid hand soap techniques. Other methods may even be more to your preference.
