4. Step-by-Step Instructions
Follow these steps to create your own 25 liters of liquid soap:

4.1. Diluting the Potassium Hydroxide (KOH)

Potassium hydroxide (KOH) is a key ingredient in making liquid soap. Before using it, it needs to be diluted to ensure safety and proper soap formation. Here’s how to do it:

Put on protective gloves and goggles to protect yourself from any potential contact with KOH.
Measure out the required amount of KOH based on the recipe you are using.

Slowly add the KOH to distilled water while stirring continuously until it is completely dissolved.
Allow the mixture to cool before proceeding to the next step.

4.2. Preparing the Coconut Oil

Coconut oil is commonly used in liquid soap recipes for its cleansing properties and ability to produce a rich lather. To prepare the coconut oil:

Measure out the required amount of coconut oil as mentioned in your recipe.
Heat the coconut oil in a pot or saucepan on low heat until it melts completely.
Once melted, remove the pot from the heat and allow the coconut oil to cool slightly.

4.3. Combining the Ingredients

Now that you have prepared the diluted KOH solution and melted coconut oil, it’s time to combine them along with other ingredients that may be specified in your recipe. Here’s how to proceed:

Slowly pour the diluted KOH solution into the pot containing the melted coconut oil.
Stir the mixture gently but thoroughly to ensure that the ingredients are well combined.

If your recipe calls for additional oils or fats, add them at this stage and continue stirring until fully incorporated.

4.4. Mixing and Cooking the Soap

To transform the combined ingredients into liquid soap, you need to mix and cook the soap mixture. Follow these steps:

Transfer the soap mixture into a large stainless steel or enamel pot.
Place the pot on the stove over low heat.
Stir the mixture continuously to prevent scorching or sticking to the bottom of the pot.
Cook the soap mixture for a period of time specified in your recipe until it reaches a desired consistency. This can take several hours, so be patient.

4.5. Diluting the Soap Paste

Once the soap mixture has cooked and reached the desired consistency, it will be in the form of a thick paste. To turn it into liquid soap, follow these instructions:

Allow the soap paste to cool for a while until it is safe to handle.
Gradually add distilled water to the soap paste while stirring continuously.

Keep adding water until the desired consistency of liquid soap is achieved. Remember to follow the recipe guidelines for the water-to-paste ratio.

4.6. Scenting and Coloring (optional)

If you prefer scented and colored liquid soap, you can add fragrance oils and colorants to personalize your creation. Here’s how:

Choose a fragrance oil or essential oil of your liking and add a few drops at a time to the liquid soap.

Stir the soap well after each addition and test the scent until you achieve the desired fragrance.

If you want to add color, choose a skin-safe colorant and add it sparingly until you achieve the desired hue. Remember to stir well after each addition.

Congratulations! You have successfully made 25 litres of liquid soap.
