When Liquid Detergent was trending in Nigeria couple of years ago, I got interested and sought for who could teach me so that I can be making my own soap for sales and private use. My first teacher used some chemical combinations that took a lot of time to get the soap formed in a way that would look presentable. After the training I lost interest because of the length of time and energy required to prepare it. However, as time goes by I stumble across another teacher through an email in my box. I went for the training and the rest is history. His own takes a little time and the soap foam very well. I am going to teach what he taught me.


In the production of liquid detergent the quantity of the ingredients is a function of the thickness, commercial value, cost of production and effectiveness of the soap. You have to measure the chemicals accurately to get the soap to the desired quality and quantity.


Do you know that you can spend as little as N2,000 to produce a thick 30 litres liquid detergent. This is good news to you if you want to do business with it because your start-up capital is low whereas the profit is huge.


Before I talk about production, let me tell you about the chemical components that make up the soap, their functions, quantity needed and costs of making the 30 litres of it. Do not worry about the measurement of the chemicals, once you give the seller the quantity quoted in the table below, he will give them to you exactly.


1 Caustic soda This is a highly corrosive (burns when touched) solid compound. It looks like granulated sugar and acts as a stain removing agent. 1/8 kg

(use only 2 table spoons full out of it)

N30  caustic soda
2 Colouring This exists in powdered form in different colours. It is changes the look of the soap from colourless to the desired colour. Dilute before use N50  colouring
3 Formalin This is a clear, colorless, aqueous solution. It is a preservative. 1/4 of a litre (use only one or two 2 caps i.e. the cover of the container bottle that is about 5ml) N50  formalin
4 Nitrosol It is in a power form, white in colour and acts as a thickening agent. 1/4 kg N600  Nitrosol
5 Perfume This is exists in liquid form. It gives your product a nice fragrance. 50ml N250  Perfume
6 Soda Ash This is a white anhydrous powdered compound. It enhances the performance of the thickening agents. 1kg N100  soda ash
7 STPP This is a white substance that acts as cleaning agent. It reacts with dirt in clothing and surfaces. 1/4 kg N50  STTP
8 Sulphonic acid This is the main acid in the soap compound It is a foaming and washing or cleansing agent. It is a brownish and thick liquid, it burns when touched. 1 ½ litres N680  Sulphonic acid
9 Texapon This is a thick pasty substance. It is a foam boosting agent 1/4 kg N150  Texapon


Note: All prices could have changed and might vary depending on the market.


Apart from the chemicals, you need a generous supply of water, bowls, measuring cup, cans and buckets, small drum, spoon, wooden or plastic ladle, basin, tub, turning stick, glove and rags to aid the production process.

      @kelechi,just add more water to the soap until it gives you the consistency you desire. Do not let it be too watery though.
