  • A funnel
  • 2.5 kg soap flakes or soap noodles

Mix the water and lye together in a large container to make the soap.

  1. Pour the 1 litres of water into the large pot and bring it to a gentle boil over medium heat.
  2. Add the soap flakes or noodles and stir continuously with the wooden spoon until fully dissolved. This may take 20-30 minutes.
  3. Once the soap flakes have dissolved, reduce heat to low and stir in the glycerine and castor oil. Mix well until fully incorporated.
  4. Use the stick blender to blend the mixture until it is uniform. This helps remove any clumps.
  5. Allow the mixture to cook on low heat for about 15 minutes, stirring occasionally. It will start to thicken to the consistency of honey.
  6. Remove from heat and allow to cool slightly. Add the fragrance oil if desired and stir well.
  7. Pour the liquid soap into storage containers using the funnel. Allow to fully cool before sealing lids.
  8. The soap will continue to thicken as it cools. Use within 1 month for best results. Shake gently before each use.

Liquid soap is a popular product that is used to clean surfaces. It is made by combining fats and alkali (sodium hydroxide or lye) in an acidic solution.

This mixture forms soap particles that are small enough to be absorbed into the surface they are cleaning.

There are several ways to make liquid soap. The most common method is to melt fat and add the alkali.

 The fats help to create an emulsified soap solution. Another method is to heat the alkali until it vaporizes and add fat. 

This method produces a harsher soap solution less likely to cause skin irritation.

Several types of fat can be used in liquid soap. Coconut oil is a popular choice because it is rich in fatty acids and doesn’t contain any chemicals.

Olive oil also has good properties for making soap but can be expensive. Some people also use palm oil, which is cheaper than other types of fat. 

To make liquid soap, you will first need to gather the ingredients. You will need some fat, alkali, and a container to store the soap. Some people also use a colorant to add color to the soap.

To make the fat-alkali mixture, you will need to melt the fat and add the alkali.

You can use either a microwave or an oven to do this, and will also need a bowl or vessel to store the soap mixture.

Once the fat and alkali are melted, add enough water so that the mixture forms a liquid. You should not use too much water, or the soap will be too thick. 

The mixture should be just thick enough so that it can be poured into the container.

If you want to add color to your liquid soap, you can do so with coloring agents. These agents are usually made from natural substances, so they are safe for use in liquid soap. 

You will need to mix the agent with enough water to make a thick solution to be used as a paintbrush. 

Once the solution is mixed well, you can brush it onto the surface you want to clean.

Are there different oils I can use?

You can use different oils according to your preferences. It is important that you ensure that the oils that you select are suitable for soap-making and that you adjust your caustic soda accordingly.

Can I drink tap water in place of distilled water

Distilled water is preferred as tap water can contain impurities which could affect soap quality.

Can I cut out the preservative and fragrance oil?

If you don’t want to use fragrance oil or preservatives, you can opt for unscented soap.

How long does soap last?

If stored in a dry, cool place and kept in an airtight container, the soap will last for up to one year.

Do I have to use the soap for my own personal use?

You can use this soap for your personal use. However, it is important that you ensure that the soap has been fully cured before using to avoid skin irritation.

How can I cure soap?

Pour the soap into a large glass or plastic container and allow it to sit for at least 4-6 weeks. The soap will begin to harden over time and any water that remains will evaporate. This will make the soap last for longer.
