Manufacturing Process
Step 1 — Prepare the LABSA Solution
Take 2 kg LABSA and mix it with 8 kg water.
Separately prepare the caustic soda solution using:
- Caustic Soda — 400 g
- Water — 2 kg
Add the caustic soda solution gradually to the diluted LABSA and neutralize the acid slurry to approximately pH 7.
Step 2 — Prepare the Main Batch
Take 70 kg water in the main mixing vessel.
Add:
- Methyl Paraben — 70 g
- Propyl Paraben — 30 g
- Di Sodium EDTA — 600 g
Mix properly.
Step 3 — Add SLES
Add 12.5 kg SLES 28% gradually into the main batch while mixing.
Step 4 — Add CAPB and CDEA
Add:
- CAPB — 1 kg
- CDEA — 1 kg
Mix until the batch becomes uniform.
Step 5 — Add Neutralized LABSA
Slowly add the prepared and neutralized LABSA solution into the main batch.
Continue mixing until completely homogeneous.
Step 6 — Adjust pH
Add 500 g citric acid and adjust the product to the required final pH. The source’s Formulation 1 process specifies adjusting the finished dishwash to approximately pH 6.
Step 7 — Add Perfume
Add 100 g water-soluble perfume and mix gently until uniformly dispersed.
Step 8 — Adjust Viscosity
Add 2 kg salt at the end.
The source specifically advises adding salt at the end and waiting 24 hours before judging the final viscosity.
Role of Ingredients
SLES 28%
Provides the primary surfactant system for cleaning and foam.
LABSA
Contributes to detergency and cleaning performance. It is neutralized with caustic soda before incorporation.
CAPB
Forms part of the surfactant system in this formulation.
CDEA
Supports the formulation’s foam and viscosity characteristics.
Di Sodium EDTA
Used as a chelating agent.
Citric Acid
Used for pH adjustment.
Salt
Used to adjust viscosity. Its required level can vary depending on the raw materials and desired thickness.
Methyl Paraben & Propyl Paraben
The preservative system specified in this formulation.
Water-Soluble Perfume
Provides fragrance to the finished product.
Important Manufacturing Tips
Control LABSA neutralization carefully: The source notes that the required caustic soda quantity can vary according to acid-slurry quality.
Don’t judge viscosity immediately: After adding salt, allow the product to stand for 24 hours before evaluating its final thickness.
Always make a trial batch: The source recommends making small batches first because chemical quality can affect the final formulation.
