HOW TO MAKE THICK AND TRANSPARENT LIQUID SOAP PRODUCTION STEP BY STEP LIST OF CHEMICALS USE IN THE PRODUCTION OF LIQUID SOAP ARE 1. NITROSOL 2. TEXAPON 3. SODA ASH 4. SULPHONIC ACID 5. SLS 6. CAUSTIC SODA 7. STPP 8. COLOUR 9. PERFUME 10. FOAM BOOSTER IS OPTIONAL Add 8 litres of water to your plastic big bowl Add 2 litres of water in another bolw and soak your SLS if the one you buy is grain type, set it aside, while it's still dissolving.... Carefully add TEXAPON into the 8 litres of water and stir immediately for about 30 seconds Then dissolve the Nitrosol in 4 litres of water, stir vigorously for about 30 seconds and add to the TEXAPON then continue stiring it for about 30 seconds to blend together Check if your SLS is dissolved, if yes add to the main mixture and stir for another 30 seconds In another bolw, dissolve the soda ash and set it aside Add SULPHONIC Acid direct to the main mixture and stir for at least 30 seconds Add the dissolved soda ash to the mixture and keep turning for another 20 seconds If you are using caustic soda, you can dissolve it separately and to the mixture and stir but I don't use it always Dissolve your stpp now and add to the main mixture and continue stiring it for about 30 seconds The next to add is foam boost if you want it Add your desired perfume and stir for 20 seconds, and then dissolve your favourite colour and add to it and stir it till it blend If you think your liquid soap will last longer in your hand, you can add preservatives like ctric acid, I did not list it because I don't use it. At this point the nice smelling fragrance is all over the place, that tells you that your liquid soap is ready for use just allow the foam to settle and you are done 👍
