These quantities are taken directly from the source formulation.
Note: The source labels this as a “Simple formula” but does not explicitly state the total finished batch weight in the formula section. Therefore, it is better not to describe it as an exact 100 kg formula without additional adjustment/testing.
Manufacturing Process
The source states “Process same as above,” referring to the preceding dishwash formulation process.
Step 1 – Dilute LABSA
Take 5 kg LABSA 96% and mix it with 20 kg water.
Mix carefully to obtain a uniform diluted acid-slurry solution.
Step 2 – Prepare Caustic Soda Solution
Take:
- Caustic Soda — 1 kg
- Water — 2 kg
Prepare the caustic soda solution separately.
The preceding process specifies neutralizing the acid slurry with caustic soda, with the amount adjusted according to the quality of the acid slurry.
Step 3 – Neutralize LABSA
Gradually add the prepared caustic soda solution to the diluted LABSA while mixing.
The preceding dishwash process specifies neutralizing the acid slurry to approximately pH 7 before incorporating it into the main batch.
Step 4 – Prepare the Main Batch
Prepare the remaining water phase and add 50 g Di Sodium EDTA.
Mix properly.
Step 5 – Add SLES 28%
Add 2.1 kg SLES 28% gradually while mixing.
Avoid unnecessarily high agitation that can create excessive foam during manufacturing.
Step 6 – Add Neutralized LABSA
Add the neutralized LABSA solution to the main batch.
Continue mixing until the formulation becomes uniform.
Step 7 – Add Citric Acid
Add 125 g citric acid and adjust the formulation as required.
The source’s preceding process uses citric acid for final pH adjustment.
Step 8 – Add Preservative
The formulation specifies:
Methyl Paraben / Propyl Paraben (3:1) — 10 g.
Step 9 – Add Perfume
Add 10 g water-soluble perfume and mix until evenly distributed.
Step 10 – Add Salt
Prepare:
- Salt — 150 g
- Water — 3 kg
Add the salt solution at the end.
The source specifically recommends adding salt at the end and waiting 24 hours before evaluating the final viscosity.
Role of Main Ingredients
LABSA 96%
Provides the main anionic cleaning component and contributes to detergency.
SLES 28%
Provides surfactant action and contributes to foam and cleaning.
Caustic Soda
Used to neutralize LABSA. Its exact requirement can vary depending on the acid-slurry quality.
Citric Acid
Used for pH adjustment in the manufacturing process.
Salt
Used for viscosity adjustment.
Di Sodium EDTA
Included as a supporting chelating ingredient.
Methyl Paraben / Propyl Paraben
The preservative system specified in this formula.
Water-Soluble Perfume
Provides fragrance to the finished product.
Important Manufacturing Tips
1. Control the neutralization
Do not rely only on the listed caustic soda quantity. Check the actual pH during neutralization because acid-slurry quality can vary.
2. Add salt at the end
Salt should be added after the other major ingredients have been incorporated.
3. Give the product time to develop viscosity
The source recommends waiting 24 hours after salt addition before judging the final thickness.
4. Always conduct a small trial
The source recommends making small batches before moving to larger production because chemical quality can affect the required quantities.
Frequently Asked Questions
1. What is the Simple Dishwash Liquid Formula?
The source’s simple formula contains LABSA 96%, SLES 28%, caustic soda, citric acid, salt, Di Sodium EDTA, preservative and water-soluble perfume.
2. How much LABSA 96% is required?
The formula specifies 5 kg LABSA 96% + 20 kg water.
3. How much SLES 28% is used?
2.1 kg SLES 28% is specified.
4. How much caustic soda is required?
The listed quantity is 1 kg caustic soda + 2 kg water.
5. Why is caustic soda added to LABSA?
It is used to neutralize the acid slurry before it is incorporated into the dishwash formulation.
6. How much salt is required?
The formula specifies 150 g salt + 3 kg water.
7. When should salt be added?
Salt should be added at the end of the process.
8. How much citric acid is used?
125 g citric acid is specified.
9. Which preservative is used?

11. How much Di Sodium EDTA is used?
50 g Di Sodium EDTA is specified.
12. Does the source give a final pH for this simple formula?
The source does not separately state a final pH value for this simple formula. The preceding dishwash process describes neutralizing LABSA to approximately pH 7 and subsequently using citric acid for final pH adjustment.
13. Can the amount of caustic soda be changed?
Yes. The source notes that caustic soda requirements can vary according to the quality of the acid slurry.
14. Can the amount of salt be changed?
The source notes that salt quantity can vary according to the desired viscosity and the quality of the acid slurry and SLES.
15. Why should a small batch be tested first?
The source recommends small-batch testing because the quality of chemicals can affect the final result and required quantities.
Conclusion
The Simple Dishwash Liquid Formula is a comparatively straightforward formulation based on LABSA 96%, SLES 28%, caustic soda, citric acid, salt, EDTA, preservative and perfume. The source specifically identifies it as a “Simple formula” and directs the manufacturer to follow the preceding dishwash manufacturing process.
For consistent commercial production, pH and viscosity should be checked experimentally, particularly because the source notes that caustic soda and salt requirements can vary with raw-material quality.
