how to product liquid deteregent?

Introduction 

To produce liquid detergent using LABSA (Linear Alkylbenzene Sulfonic Acid), SLES (Sodium Lauryl Ether Sulfate), caustic soda, and soda ash, you can follow these general steps:

Ingredients Needed:

1. LABSA: Acts as the primary surfactant (cleaning agent).
2. SLES: Provides additional foaming and cleaning properties.
3. Caustic soda (Sodium Hydroxide): Used to adjust pH and as a thickening agent.
4. Soda ash (Sodium Carbonate): Helps to adjust pH and acts as a builder.

Equipment Needed:

• Mixing tank or vessel
• Heating source (if necessary)
• Stirrer or mixer
• pH meter
• Measuring instruments (scales, graduated cylinders, etc.)
• Safety equipment (gloves, goggles, etc.)

Process:

1. Preparation of LABSA Solution:

   • Measure out the required amount of LABSA and add it to the mixing tank.
   • Gradually add water to dilute the LABSA. Stir well until LABSA is fully dissolved.
   • LABSA is usually quite acidic, so you may need to adjust pH later with caustic soda.

2. Preparation of SLES Solution:

   • Measure out the required amount of SLES and add it to a separate container.
   • Add water to dissolve the SLES completely. Stir until it forms a homogeneous solution.

3. Mixing LABSA and SLES:

   • Once LABSA and SLES solutions are prepared and homogeneous, combine them in the mixing tank.
   • Stir the mixture thoroughly to ensure uniform distribution.

4. Preparation of Caustic Soda Solution:

   • Measure out the required amount of caustic soda.
   • Add water to dissolve the caustic soda. Be cautious as this solution can get hot and is highly alkaline.

5. Mixing with Soda Ash:

   • Measure out the required amount of soda ash.
   • Gradually add soda ash to the mixing tank while stirring continuously to avoid clumping.

6. Adjusting pH:

   • Use a pH meter to monitor the pH of the mixture.
   • Slowly add small amounts of caustic soda solution to adjust the pH to the desired range (typically pH 7-9, depending on formulation).

7. Adding Perfumes and Colorants (Optional):

   • Once the pH is adjusted and the mixture is stable, you can add perfumes or colorants if desired.
   • Stir well to ensure these additives are evenly distributed.

8. Testing and Adjustments:

   • Test the final product for viscosity, clarity, and cleaning performance.
   • Make any necessary adjustments to pH, viscosity, or composition based on testing results.

9. Packaging:

   • Once the detergent has passed quality control checks, it can be transferred to packaging containers (bottles, drums, etc.).

Safety Considerations:

• Wear appropriate personal protective equipment (PPE) such as gloves and goggles when handling chemicals.
• Work in a well-ventilated area to avoid inhaling fumes from chemicals.
• Handle caustic soda and soda ash with care as they are corrosive and can cause burns.

Notes:

• The exact formulation and quantities of LABSA, SLES, caustic soda, and soda ash will depend on your desired product specifications (e.g., viscosity, foam characteristics).
• Always follow safety guidelines and local regulations when handling chemicals and manufacturing detergents.

By following these steps, you can produce liquid detergent using LABSA, SLES, caustic soda, and soda ash effectively. Adjustments may be needed based on specific product requirements and testing results. prepared by Tasfu
