This is the 4th formulation under the Liquid Handwash category in the provided formula book. It is designed around SLES 28%, CAPB and Lauramine Oxide (LAO), with HPMC and glycerine used in the initial thickening phase.
Handwash Formula
| Raw Material | Quantity |
|---|---|
| Water | 100 kg total |
| Disodium EDTA | 100 g |
| HPMC | 300 g |
| Glycerine | 3 kg |
| SLES 28% | 50 kg |
| CAPB | 6.67 kg |
| Lauramine Oxide (LAO) | 6 kg |
| MCIT/MIT | 100 g |
| Perfume | 150 g |
| Citric Acid / Caustic Soda | As required for pH 7–8 |
| NaCl | If required for thickening |
The source specifies “Water 100 total”, indicating water is adjusted as part of the total batch quantity.
Manufacturing Process
Step 1 – Prepare the Thickening Phase
Take part of the water and add:
- Disodium EDTA — 100 g
- HPMC — 300 g
- Glycerine — 3 kg
The source specifically states to mix these ingredients for thickness.
Step 2 – Add the Surfactants
Add:
- SLES 28% — 50 kg
- CAPB — 6.67 kg
- LAO — 6 kg
Mix carefully until the surfactants are uniformly incorporated.
Step 3 – Add Preservative
Add MCIT/MIT — 100 g and mix properly.
Step 4 – Add Perfume
Add 150 g perfume and mix gently to obtain a uniform product.
Step 5 – Adjust pH
Adjust the final product to pH 7–8 using citric acid or caustic soda as required. The source does not specify a fixed quantity for either pH-adjusting material.
Step 6 – Adjust Viscosity
If additional thickening is required, NaCl can be used, as specified in the source.
Role of Key Ingredients
SLES 28% – Primary cleansing and foaming surfactant.
CAPB – Secondary surfactant in the cleansing system.
Lauramine Oxide (LAO) – Surfactant supporting cleaning and foam performance.
HPMC – Thickening component specified in the initial thickening phase.
Glycerine – Humectant included in the formulation.
Disodium EDTA – Chelating ingredient included in the formulation.
MCIT/MIT – Preservative specified by the source.
Perfume – Provides fragrance to the finished handwash.
NaCl – Optional viscosity adjustment according to the source.
Important Manufacturing Points
- Maintain good mixing while incorporating the surfactants.
- HPMC and glycerine are specifically mixed together with Disodium EDTA for the thickness phase.
- Do not assume a fixed quantity of citric acid or caustic soda—the source only specifies adjusting to pH 7–8.
- NaCl is listed as “if required for thickening”, so its quantity is not fixed in the source.
- Conduct a small pilot batch before commercial-scale production.
