Where to Get Your Ingredients

You can buy everything at any chemical shop near you. Just ask for soap-making ingredients, specifying the number of liters you want to make.

Safety First!

Since some ingredients are chemicals, please follow these precautions:  

• Always wear gloves and a face mask to protect yourself.  
• Work in a well-ventilated area to avoid inhaling strong fumes.  
• Avoid direct skin contact with chemicals, especially caustic soda.
• Rinse your spatula thoroughly after every step to prevent unwanted reactions.  

Ingredients and Their Uses

1. Colouring Agent – Gives the soap a nice, attractive color.
2. Caustic Soda – Breaks down dirt and grease for better cleaning. Handle with care!
3. Sulfonic Acid – Removes stains and improves foaming. Essential for effective cleaning.  
4. Texapon – Works with sulfonic acid to boost foaming and make the soap milder.  
5. Sodium Tripolyphosphate (STPP) – Helps the soap lather better and enhances its cleaning power.  
6. Soda Ash – Softens water so the soap can work well, even with hard water.  
7. Sodium Lauryl Sulfate (SLS) – A foaming agent that gives the soap a rich, bubbly lather.  
8. Nitrosol – A thickening agent that gives the soap a smooth, gel-like consistency.  
9. Soap Booster – Strengthens the soap’s ability to cut through grease and dirt.  
10. Fragrance – Adds a nice scent (choose lemon, floral, fruity, or any fragrance you like).  
11. Water – The base ingredient that dissolves and blends everything together.  

Step-by-Step Process

Step 1: Mix the Colouring Agent

• In a small bowl, dissolve the colouring agent in water.  
• Stir with a wooden spatula until fully mixed. 
• Rinse your spatula before moving to the next step.

Step 2: Prepare the Caustic Soda Mixture

• In another bowl, mix caustic soda with water (BE CAREFUL HERE PLEASE,CAUSTIC SODA IS A VERY CORROSIVE CHEMICAL!)
• Stir thoroughly until fully dissolved. 
• Set it aside and rinse your spatula immediately.

Step 3: Prepare the Sulfonic Acid + Texapon Mixture

• In a separate bowl, mix sulfonic acid with texapon.
• Stir until well combined.  
• Rinse your spatula after this step.

Step 4: Mix STPP with Soda Ash

• In another bowl, combine STPP and soda ash.  
• Stir well to prevent lumps.  
• Rinse your spatula before continuing.

Step 5: Prepare the SLS Mixture

• Add SLS to a bowl of water.  
• Stir until completely dissolved. 
• Rinse your spatula afterward.

Step 6: Set Up the Soap Base

•  In a large basin or bucket, add nitrosol to your desired amount of water.  
• Stir well until it thickens and forms a smooth gel-like base.  

Step 7: Add the Caustic Soda Mixture 

• Gently pour in the caustic soda mixture from Step 2 while stirring continuously.  
• Mix thoroughly to ensure it blends well with the soap base.  

Step 8: Add the Sulfonic Acid + Texapon Mixture 

• Pour in the sulfonic acid + texapon mixture from Step 3.  
• Stir well to combine all ingredients evenly.  

Step 9: Add the STPP + Soda Ash Mixture

• Add the STPP + soda ash mixture from Step 4.  
• Mix thoroughly until no lumps remain.  

Step 10: Add the Remaining Ingredients 

• Add the colouring agent from Step 1.  
• Pour in the soap booster to enhance cleaning power.  
• Add your preferred fragrance to give the soap a nice scent.  
• Finally, add the SLS mixture from Step 5.  
• Mix everything well until fully blended.  

Step 11: Let It Rest

• Leave the soap mixture for 6–8 hours, or even up to 24 hours to allow all ingredients to blend properly.  I left mine for 8 hours just because I was so eager, but you can leave yours to rest for even longer.

Step 12: Packaging

• After resting, stir the mixture again and pour it into containers or squeeze bottles for easy use. I used old water bottles and kegs because I wasn't going to sell them, but if you want to use yours for commercial purposes, then you can buy squeeze bottles from the market and pour the soap into them.

How Well Does This Soap Work?

I tested this soap on greasy plates and dirty clothes — and the results were amazing! It foams well, removes grease effortlessly, and leaves everything fresh and clean. If you follow this process correctly, I'm sure you’ll get the same great results.
