Manufacturing Process
The source specifies “Process same as above”, referring to the preceding Handwash Liquid process.
Step 1 – Prepare the Water Phase
Take 55 kg water in the mixing vessel.
Add:
- Disodium EDTA — 250 g
- DMDM — 100 g
Mix properly.
Step 2 – Add Surfactants
Add the following gradually:
- SLES 28% — 30 kg
- SLS — 150 g
- ALS — 150 g
- CMEA — 1 kg
- CAPB — 7 kg
- CDEA — 1 kg
Mix carefully until the surfactant system is uniform.
Step 3 – Add Conditioning Ingredients
Add:
- Glycerine — 2 kg
- Salicylic Acid — 50 g
- Propylene Glycol — 50 g
- PEG-40 — 200 g
Continue mixing until properly incorporated.
Step 4 – Add Pearl Paste
Add 980 g Pearl Paste and mix thoroughly until the pearlized appearance is uniform.
Step 5 – Add Citric Acid
Add 400 g citric acid as specified in the formulation.
The source’s preceding process uses citric acid during the later stage of manufacturing.
Step 6 – Add Salt
Add 1.1 kg salt.
Salt should be incorporated carefully because it can significantly affect the viscosity of surfactant-based handwash systems.
Step 7 – Add Fragrance
Add 50 g fragrance and mix gently until evenly distributed.
Role of Main Ingredients
SLES 28%
The primary surfactant in this formulation, contributing to cleansing and foam.
CAPB
An amphoteric co-surfactant that forms part of the cleansing and foaming system.
CDEA
Supports the surfactant system and contributes to foam and viscosity.
SLS & ALS
Additional anionic surfactants contributing to cleansing and foam.
CMEA
Included as part of the surfactant/consistency system.
Pearl Paste
Provides the characteristic pearlized appearance of the handwash.
Glycerine
Included as a conditioning/humectant ingredient.
Disodium EDTA
Included as a chelating/supporting ingredient.
DMDM
The preservative specified in the formulation.
Citric Acid
Included as the pH-adjusting ingredient.
Salt
Used as part of the viscosity adjustment system.
PEG-40
Included in the formulation as a supporting ingredient.
Fragrance
Provides the desired fragrance.
Important Manufacturing Tips
1. Control mixing
Because the formulation contains several surfactants, excessive agitation can create unnecessary foam and make processing difficult.
2. Add Pearl Paste carefully
Pearl paste should be mixed sufficiently to achieve a consistent pearl appearance throughout the finished product.
3. Monitor viscosity
Salt has a strong effect on viscosity. Avoid assuming that increasing salt will always produce a thicker product.
4. Check pH
The formulation contains citric acid, but the source does not provide a separate final pH target for this Second Pearl Handwash formulation. Therefore, the final pH should be established and verified during product testing rather than assigning an unsupported value.
5. Conduct a trial batch
The source recommends making small batches first because raw-material quality can affect the final product and required quantities.
