  1. Water (20 ltrs)
  2. Nitrosol or Antisol or C.M.S (1 kg)
  3. Caustic soda or soda ash (½ kg)
  4. Sulphonic acid (3 liters)
  5. Texapon (1 liter)
  6. Sodium laurate sulphate (5 – 6 tbsp)
  7. Sodium Tripolyphosphate (5 – 6 tbsp)
  8. Colorant (As desired)
  9. Perfume (As desired)

We have highlighted the functions of these ingredients below:

  1. Water

Water is the main solvent needed for the dissolution of the various ingredients and during the fermentation phase. It is an essential component in the production of liquid soap.

  1. Nitrosol/Antisol

This is the thickening agent use in the liquid soap production process. It comes as a whitish substance and has the texture of powdered milk. The difference between Nitrosol and Antisol is that the former dissolves immediately in water while the latter takes a longer time.

  1. Caustic Soda

It is whitish crystalline substance resembles granulated sugar. It forms a strong base when dissolved in water and can be corrosive if in contact with the skin. It is an essential ingredient in the soap making process. It is the stain/dirt removing agent in the liquid soap.

  1. Soda Ash (Sodium carbonate)

This is also a whitish substance but with much coarse grains, it serves to regulate the concentration of the caustic soda which ordinarily is corrosive to the skin by neutralizing it.

  1. SLS (Sodium Lauryl Sulphate)

The SLS resembles rice grains and it’s whitish in colour. It is a surfactant which helps to lower the surface tension of the aqueous solution. It is the main active foaming agent.

  1. Texapon

Texapon is a pasty and jellylike substance that serves as a foaming agent and foaming booster. Many liquid soap producers don’t use Texapon and SLS together in same production because they perform the same function.

  1. Sulphonic Acid

This is a dark looking liquid substance that boosts the performance of the SLS. It is also a foaming and cleaning agent. It is different from sulphuric acid which is a very strong acid and can be very corrosive.

  1. STPP (Sodium Tripolyphosphate)

STPP is a sodium salt of triphosphoric acid. It has the appearance of white crystal powder and looks very much like a table salt. It is a strong cleaning agent too and helps the SLS to work on its full potential.

  1. Foaming Booster

As the name implies, this ingredient makes the liquid soap foam well.

  1. Formalin

This is a preservative agent. It should be used if the soap will be stored for a long time like six months. This is useful for those producing for commercial purposes.

  1. Colour

The colour comes in the form of powder and should be diluted with water before adding to the soap mixture. The colour adds beauty to the finished product. Most producers go with green colour.

  1. Glycerine

Glycerine helps your skin to remain hydrated and soft after using the soap.

  1. Perfume

This gives your soap the attractive fragrance. There are different options such as lemon, pineapple, ambipur. lavender or strawberry fragrance.

  1. Vitamin E

This vitamin offers a great deal of protection to the skin and prevents wrinkles.

Procedure

Soap making requires a great deal of patience especially during stirring in order to ensure the chemical(s) added at each stage dissolves properly before adding the next one.

When you’re working with smaller volume production such as 8 litres or 10 litres, you should follow the same process but work on your ratios. The vendors selling these chemicals usually sell them already measured according to the volume of liquid soap to be produced.

You will need to tell them how much volume you want to produce and they will give you the quantity of chemicals you require. It is also advisable to start with small volume and grow big later.

Here are the steps to take:

  1. Dissolve caustic soda in one liter of water and allow to cool
  2. In a separate container pour in sulphonic acid, add perfume, texapon and then add 3 to 4 liters of water and stir very well for some minutes
  3. Dissolve the SLS with 2 tin milk cups of water
  4. Dissolve the STPP with 2 tin milk cups of water
  5. Dissolve 1 kg of nitrosol into 20 liters of water and stir. It dissolves almost immediately. If you’re using C.M.C you’ll have to wait for 2 days to dissolve properly
  6. Add the already dissolved texapon, sulphonic acid and, perfume into the dissolved nitrosol or C.M.C and stir very well
  7. Pour in dissolved caustic soda or soda ash into the dissolved solution of nitrosol or C.M.C and stir
  8. Add dissolved STPP and SLS and stir
  9. Add formalin for preservation
  10. Dissolved colorant into the water, mix well then add to the solution and stir thoroughly
  11. If you feel it is too thick add a little water and stir
  12. Leave the solution for some hours.
  13. Package and sell
