Car Shampoo

To produce 20 liters of car shampoo, you need to scale up the ingredients proportionally and follow precise steps to ensure uniformity and quality. Below is the detailed guide:

Ingredients for 20 Liters of Car Shampoo:

1. Water: 13.06 liters (13,060 ml) – 653 ml × 20
2. SLES70% (sodium lauryl ether sulfate): 4.8 liters (4,800 ml) – 240 ml × 20
3. SDBS (sodium dodecylbenzene sulfonate): 800 ml – 40 ml × 20
4. CDE (coconut diethanolamide): 400 ml – 20 ml × 20
5. Urea: 200 grams – 10 grams × 20
6. Formalin: 20 ml – 1 ml × 20
7. Perfume: 20 ml – 1 ml × 20
8. E-wax (emulsifying wax): 200 grams – 10 grams × 20
9. Dye (optional): As needed
10. Salt (sodium chloride): 500 grams – 25 grams × 20

Equipment Needed:

• A large, clean mixing container (25–30 liters capacity).
• Stirring rod or mechanical mixer.
• Heat source (optional, for dissolving wax or urea more easily).
• Measuring tools: a scale for solids and graduated containers for liquids.
• Protective gear: gloves, goggles, apron, and mask.

Step-by-Step Instructions:

Step 1: Prepare the Water Base

1. Measure 13.06 liters of water and pour it into the mixing container.
2. Ensure the water is clean and at room temperature. If dissolving the E-wax or urea proves difficult, you may slightly warm the water to 30–40°C but avoid overheating.
3. Stir gently to remove any air bubbles and create a uniform base.

Step 2: Dissolve Urea

1. Weigh 200 grams of urea and add it to the water while stirring.
2. Stir until the urea is completely dissolved.
   • Observation: The water should remain clear without any residue at the bottom.
3. If heating was applied, allow the solution to cool back to room temperature before proceeding.

Step 3: Add SLES70%

1. Measure 4.8 liters of SLES70% using a graduated container.
2. Gradually add the SLES70% to the water-urea solution while stirring continuously.
   • Observation: The mixture will begin to foam, and viscosity will increase slightly.
3. Stir for 5–10 minutes until the SLES70% is evenly distributed and no clumps remain.

Step 4: Add SDBS

1. Measure 800 ml of SDBS.
2. Slowly pour the SDBS into the mixture while stirring.
   • Observation: The surfactant will enhance foam generation and cleaning properties.
3. Stir thoroughly for 5–10 minutes to ensure uniform incorporation.

Step 5: Add CDE

1. Measure 400 ml of CDE using a graduated container.
2. Slowly add the CDE to the solution while stirring continuously.
   • Observation: The CDE will stabilize the foam and add thickness to the shampoo.
3. Stir for 5–10 minutes to ensure even mixing.

Step 6: Melt and Add E-Wax

1. Weigh 200 grams of E-wax and melt it gently over low heat until it becomes liquid.
2. Gradually add the melted E-wax to the mixture while stirring continuously.
   • Observation: The E-wax will contribute to a creamy texture and enhance emulsification.
3. Stir for 10–15 minutes to ensure the E-wax is fully integrated.

Step 7: Add Formalin

1. Measure 20 ml of formalin and add it to the mixture.
2. Stir gently to distribute the preservative throughout the solution.
   • Caution: Handle formalin with care and ensure proper ventilation.

Step 8: Add Perfume

1. Measure 20 ml of perfume and add it to the mixture.
2. Stir slowly to avoid excessive foaming.
   • Observation: The solution will acquire the desired fragrance.

Step 9: Add Dye (Optional)

1. Add a small amount of dye (e.g., a few drops) to achieve the desired color.
2. Stir thoroughly to ensure the dye is evenly dispersed.
   • Tip: Test the dye in a small portion of the mixture first to confirm the color intensity.

Step 10: Adjust Viscosity with Salt

1. Weigh 500 grams of salt and dissolve it in 500 ml of warm water separately.
2. Gradually add the salt solution to the car shampoo mixture while stirring.
   • Observation: The viscosity will increase as you add salt. Monitor the thickness closely to achieve the desired consistency.
3. Stir thoroughly for 10–15 minutes to ensure uniform texture.

Final Checks:

1. Consistency: The shampoo should be thick but pourable, with no lumps or separation.
2. Appearance: Uniform in color and texture.
3. Fragrance: Ensure the perfume scent is evenly distributed and noticeable.

Storage Instructions:

1. Transfer the finished car shampoo into clean, labeled storage containers (e.g., 20-liter buckets or smaller bottles for distribution).
2. Seal the containers tightly to prevent contamination.
3. Store in a cool, dry place away from direct sunlight and extreme temperatures.

Safety Precautions:

• Wear protective gloves, goggles, and a mask during the process to avoid irritation.
• Handle formalin and other chemicals with care in a well-ventilated area.
• Label the final product appropriately to avoid misuse.

By following these detailed instructions, you will produce a high-quality 20-liter batch of car shampoo ready for use or sale.
