The following write up shows step by step guide on how to make liquid soap. Please follow the steps very carefully using the right measurement given to you.

Safety precautions you must take during soap production

Please use protective gloves on both hands and if you are allergic to odours of chemical, use a nose mask.
Please do not make the production close to naked flames such as unprotected candle flames or flames from any burning material. This is because some of the soap chemicals are inflammable
Keep soap chemicals out of reach of children as most of the soap chemical crystals have a similar appearance as common table salt. (NaCl)
Avoid direct contact of soap chemicals with the skin or eyes. In case of an accident, please wash immediately with plenty of water.
Please do not taste any soap chemicals.
The soap chemicals you will purchase from the market are made up of the following chemicals and they are usually labeled in the order in which you will dissolve them in the water.

a. 1.Nitrosol /Antisol
b. 2.Caustic soda
c. 3.Soda ash


d. 4.STPP (Sodium- tripolyphosphate)
e. 4.SLS/Texapon (Sodium Laurel sulphate)
f. 4.Foaming Booster
g. 4.Sulphonic
h. 5. Perfume
i. 5. Colour
j. 6. Formalin

Non-chemical materials required

a. Two 20 liter buckets(calibrated )
b. Long stake (stirring stick)
c. Bowls
d. Hand gloves
e. Nose mask (optional)



Wear your hand gloves and measure 5 liters of clean water into 20 lit. Capacity bucket
Insert the stake into the bucket containing 5 lits of water
Take the soap chemical label no, 1 i.e. Nitrosol/antisol

Step 1

1. Open it very carefully and gently pour it into the container containing 5 liters of water and simultaneously stir the mixture very hardly. Continue to pour the white powder little by little and stir until the powder is fully dissolved. Please note that when using antisol the dissolution is very slow, you may have to stir for a while before all the particles will dissolve. Nitrosol dissolves faster than antisol. This is the reason why Nitrosol is referred to as instant and antisol is referred to as overnight.
2. Now take the soap item labeled no.2 i.e. caustic soda and dissolved it in another freshwater of about 1liter in another container or bowl. Stir the mixture thoroughly until all the caustic soda crystals are dissolved. Now pour the dissolved caustic soda solution into the bucket containing dissolved Nitrosol and stir very well. The total solution becomes a bit thicker at this time
3. The third soap chemical is soda ash. Take the soda ash and also dissolve it in about one liter of water. Stir it properly until all the soda ash crystals dissolved. Just like you did in the case of caustic soda, pour the soda ash solution in the solution containing Nitrosol and caustic soda. Stir the total solution very well.

Step 2.

In the second step, there is no particular order, i.e. any of the chemicals listed below can go into the solution.
4. SLS/Texapon
4. Foaming Booster
4. Sulphonic
Dissolve the STPP and SLS in two different bowls containing about 1 liter of water. Make sure that the crystals of both salts dissolved completely. Pour the SLS solution into the solution containing Nitrosol, Caustic soda, and soda ash and stir. Also pour that of STPP into the solution and stir.
You can now pour the Forming boater and sulphonic and continue to stir.
You can now add item no. 5 i.e. perfume and colour. Dissolve the colour in a small quantity of water before pouring it into the final solution. Add your perfume
Now add water to get the desired thickness

Side Notes:

You have been introduced to the major chemicals for liquid soap production. However, there are cases where the following chemicals are also added to the soap chemicals, i.e. Texapon and formalin
Texapon stands in place of SLS and formalin is used as a preservative. Domestic preparation does not necessarily require preservation. But in case you need it just add a little to the soap solution.
