In this article, I will guide you through the process of making liquid soap from scratch, providing you with step-by-step instructions and essential tips. Whether you’re a beginner or an experienced soapmaker, this guide will help you create high-quality liquid soap that is gentle on the skin and free from harmful ingredients. So, are you ready to discover the art of homemade liquid soap? Let’s get started!

The Process for Making Liquid Soap

In the world of soapmaking, liquid soap offers a unique and versatile product that can be used for various purposes. The process for making liquid soap is different from traditional bar soap, requiring specific ingredients and techniques to achieve the desired consistency and texture. In this section, I will guide you through the step-by-step process of making liquid soap, from creating a soap paste to diluting it into the final product.

To start the process of making liquid soap, you will need to create a soap paste. This is done using the hot process method, which involves combining oils with potassium hydroxide (KOH) to saponify the oils. Unlike bar soap, which uses sodium hydroxide, liquid soap requires the use of potassium hydroxide to achieve the desired results.

The soap paste is created by dissolving potassium hydroxide in water, also known as a lye solution. This solution is then mixed with a combination of oils, such as coconut oil, olive oil, and other oils suitable for liquid soapmaking. The mixture is heated and stirred until the oils and lye solution have completely reacted, resulting in a thick, semi-translucent soap paste.

Once the soap paste is formed, it needs to be properly diluted to create the liquid soap. This can be done by slowly adding water or another liquid of choice to the soap paste, adjusting the amount to achieve the desired consistency. Dilution is a crucial step as it determines the thickness and texture of the final liquid soap.

After dilution, the liquid soap can be scented and colored according to personal preferences. Fragrance oils or essential oils can be added to give the soap a pleasant scent, while soap dyes or colorants can be incorporated to create visually appealing variations. It’s important to note that fragrance and color should be added after the soap paste has been diluted and adjusted, as they can affect the final product’s consistency.

Let’s take a moment to summarize the process for making liquid soap:

  1. Create a soap paste by combining oils and potassium hydroxide (KOH).
  2. Dilute the soap paste with water or another liquid to achieve the desired consistency.
  3. Add fragrance and color to the diluted soap, if desired.

With these steps, you can successfully make your own liquid soap at home. The process may require some practice and experimentation to achieve the desired results, but with time, you’ll be able to fine-tune your technique and create unique liquid soaps that meet your personal preferences.

Tips for Making Liquid Soap

If you’re interested in making your own liquid soap, there are a few tips and tricks that can help you achieve great results. Here are some important things to keep in mind:

1. Superfatting Liquid Soap

Unlike bar soap, you cannot superfat liquid soap to the same degree. The maximum superfat for liquid soap is around 3%. Superfatting too much can result in a sticky or oily soap that doesn’t lather well. So, be mindful of the superfat percentage when formulating your recipe.

2. Choosing the Right Oils

Using the right oils is crucial for successful liquid soapmaking. Oils like olive oil, coconut oil, and castor oil are great options as they contribute to a stable and mild liquid soap. These oils have the right balance of cleansing and moisturizing properties, resulting in a high-quality soap.

3. Dilution Process

When it comes to diluting the soap paste into liquid soap, patience is key. Start by adding water to the soap paste a little at a time, stirring well between each addition. This gradual dilution process allows you to control the consistency and thickness of the final liquid soap. Keep in mind that most liquid soaps are thinner than what you might expect, so don’t be alarmed if it appears less viscous.

4. Testing and Adjustment

Before adding fragrance or other additives, it’s important to test your liquid soap for excess oil or lye. Take a small sample of the diluted soap and perform a thorough pH test. Adjust the recipe if needed by adding a small amount of lye solution or additional water to achieve the desired properties.

By following these tips, you’ll be well-equipped to create your own high-quality liquid soap. Experiment with different oils, colors, and fragrances to customize your soap and make it your own.

To make high-quality liquid soap, it is essential to have the right tools and ingredients. Here are the recommended tools and ingredients that will help you achieve success in your liquid soapmaking journey:


  • Slow Cooker: A slow cooker is a versatile tool that provides gentle heat for the soapmaking process.
  • Thermometer: A thermometer is crucial for monitoring the temperature during various stages of liquid soapmaking.
  • Scale: Accurate measurement of ingredients is essential, and a scale helps ensure precision.
  • Measuring Cups: Measuring cups are crucial for measuring both oils and liquids accurately.
  • Stick Blender: A stick blender helps emulsify the soap mixture and speeds up the saponification process.
  • Potato Masher or Flat Whisk: These tools are useful for breaking down any lumps and ensuring a smooth consistency in the soap paste.


  • Oils: Sunflower oil, coconut oil, and other oils like olive oil or castor oil are commonly used in liquid soapmaking.
  • Potassium Hydroxide (KOH): Unlike bar soap, liquid soap requires potassium hydroxide to create the soap paste. It is essential to use high-quality KOH for successful liquid soapmaking.
  • Distilled Water: Distilled water is used for preparing the lye solution and dilution of the soap paste.
  • Additives: Optional additives like boric acid or borax can enhance the performance of the liquid soap. Fragrance or essential oils can add pleasant scents, and soap dye or colorant can be used for customization.

By using these recommended tools and ingredients, you will have the necessary foundation to create beautifully crafted liquid soap. Let your creativity flow as you experiment with different combinations and techniques.

Common Challenges in Liquid Soapmaking

While making liquid soap can be a rewarding process, there are some challenges that soapmakers often encounter. Let’s discuss some of the common challenges in liquid soapmaking:

Achieving a Clear Liquid Soap

One common challenge in liquid soapmaking is achieving a clear soap. Using brine instead of water in the lye solution can result in a cloudy soap. To ensure clarity, it’s important to use distilled water when making the lye solution. This will help prevent impurities that can cloud the soap. Additionally, properly mixing the soap paste and diluting it adequately can also contribute to achieving a clear and transparent liquid soap.

Dealing with Additives That Create Cloudiness

Certain additives like goat milk, clays, and botanicals can create a breeding ground for mold and bacteria, resulting in a cloudy soap. While these additives can offer beneficial properties to the soap, it’s important to be cautious when using them. Ensure proper sanitation and consider adding preservatives if necessary to prevent cloudy soap due to bacterial contamination.

Managing Excess Oil or Lye

Another challenge in liquid soapmaking is dealing with excess oil or lye in the soap. Excess oil can make the soap greasy, while excess lye can cause skin irritation. To address these issues, it’s crucial to test the soap for excess oil or lye using pH testing strips. If necessary, adjust the soap by adding more oils or diluting the soap further until the desired balance is achieved.

Addressing these challenges and taking proactive measures can help ensure the production of high-quality liquid soap. By following proper procedures, maintaining good hygiene practices, and adjusting the soap as needed, soapmakers can overcome these challenges and create exceptional liquid soaps.
