Equipments needed for the production of liquid soap
Equipments required for liquid soap production include:
1. Big mixing bowl
2. Wooden/steel spoon
3. Measuring bowl
4. Hand gloves
5. Nose mask
6. Slow cooker
Ingredients needed for the production of liquid soap
Ingredients required include:
1. Sodium Tripolyphosphate (STPP)
2. Soda ash
3. Sulphonic acid
5. Caustic soda
6. Nitrosol/Antisol/Carboxy methyl cellulose (C.M.C)
7. Sodium laurate sulphate (SLS)
9. Colorant and Perfume(optional)
Each of the chemicals has a specific function to perform in the soap production;
STPP: It appears in white crystal powder form. It serves as a cleaning and thicken agent. Also serves as a catalyst for SLS.
Texapon: It is a jelly- like substance which serves as foaming agent. It serves the same purpose with SLS. Hence, can be used together in production or use one and leave the other.
SLS: It is a whitish chemical that looks like rice grains. It lowers the surface tension of the aqueous solution and a foaming agent.
Nitrosol/Antisol/C.M.C: It is a whitish substance in charge of thickening the production. The only difference is that Antisol requires much time to dissolve in water than Nitrosol and C.M.C.
Caustic Soda: Looks like a granulated sugar. When dissolved in water, it forms a base which is very corrosive when in contact with the skin (in excess can peel the skin).It is in charge of stain/dirt removal.
Soda ash (sodium carbonate):This functions as a regulator. It regulate the concentration of caustic soda by neutralising it. It is also a cleaning agent.
Sulphonic acid: Do not mistake this for sulphuric acid. Sulphonic acid is a very strong acid and can be very corrosive. Sulphonic acid is a foaming and cleaning agent and alalso boost the performance of SLS in soap production.
Formalin: This is optional. It serves as a preservative agent, used if the soap is to be stored for a long time. For commercial purposes, it is advisable to use formalin. It can cause cancer if abused.
Colourant: This comes in powdered form. It gives a specific colour to the soap mixture, hence, enhancing it’s beauty and attractiveness.
Perfume: This gives the soap a sweet fragrance. There are different perfumes for liquid soap production. Look for sweet and attractive one.

2. Liquidify the soda ash in bowl B using water. Leave for 24 hours or overnight.
3. Dissolve the SLS in bowl C and leave for 24 hours or overnight.
4. Soften the STPP in bowl D just before production.
5. Mix the Sulphonic acid and Texapon together in bowl E and stir gently until mixture becomes homogeneous. It is an exothermic process (i.e gives out heat especially when properly done) so should be done in a well ventilated environment.
6. Dissolve Nitrosol or Antisol whichever you choose to use in bowl F just before production.
7. Colorant should be liquidify with a small quantity of water.
Ensure all the chemicals are properly dissolved before mixing together.
8. Pour the mixture in bowl E into a big mixing bowl G, add the mixture in bowl C and F and stir properly.
9. Add the dissolved caustic soda in bowl A to bowl G and stir carefully.
10. Add the dissolved STPP in bowl D and keep stirring.
11. If formalin is to be used, add it at this point and keep stirring.
12. Allow the lather formed by the mixture to disappear and then add your dissolved Colorant and perfume to the mixture and stir properly.
13. Water should be added gently while stirring the mixture until the desired thickness is attained.
When the above steps are properly followed, your liquid soap is ready for use and you can package them for sale. Although the liquid soap may not be clear immediately after production, you can wait for 24 hours to have a clear liquid soap.
