Manufacturing Process

The source provides the following sequence for manufacturing this handwash formulation.

Step 1 – Prepare the Water Phase

Take the specified 60 kg water in the mixing vessel.

Add 250 g Di Sodium EDTA and 100 g DMDM.

Mix properly.

Step 2 – Add the Surfactants

Add the following ingredients into the water:

• SLES 28% — 24 kg
• ALS — 2 kg
• Coco Glucoside — 3 kg
• CAPB — 1 kg
• CMEA — 2 kg

Mix until the ingredients are properly incorporated.

Step 3 – Add Conditioning & Supporting Ingredients

Add:

• Glycerine — 2 kg
• Salicylic Acid — 50 g
• Propylene Glycol — 500 g
• PEG-40 — 250 g

Continue mixing until the batch is uniform.

Step 4 – Add Citric Acid

Add 1 kg citric acid as specified in the formulation.

The source lists citric acid as part of the subsequent addition stage.

Step 5 – Prepare the Salt Solution

Dissolve:

550 g salt + 3 kg water

The source specifically says:

“Always add salt dissolved in water.”

Add the salt solution gradually while mixing.

Step 6 – Add Fragrance and Colour

Finally add:

• Fragrance — 230 g
• Colour — 50 g (1% solution: 10 g as listed)

Mix until the product becomes uniform.

Role of Main Ingredients

SLES 28%

A major surfactant in the formulation, contributing to cleansing and foam.

ALS

An anionic surfactant included to support the cleansing and foaming system.

Coco Glucoside

A nonionic surfactant included as part of the surfactant blend.

CAPB

A co-surfactant used as part of the cleansing/foaming system.

CMEA

Included in the formulation as part of the surfactant and consistency system.

Glycerine

Included as a humectant/skin-conditioning ingredient.

Propylene Glycol

Used as a supporting ingredient in the formulation.

PEG-40

Included in the formulation as specified by the source.

Di Sodium EDTA

Used as a supporting chelating ingredient.

DMDM

The preservative specified in this formulation.

Salicylic Acid

Included in the formulation at 50 g.

Citric Acid

Included during the final stages of formulation.

Salt

Used as part of the viscosity-adjustment system and is specifically instructed to be added dissolved in water.

Fragrance

Provides the desired fragrance.

Colour

Provides the desired visual appearance.

Important Manufacturing Tips

1. Always dissolve salt before addition

The source specifically instructs that salt should be dissolved in water before adding it to the formulation.

2. Add surfactants carefully

SLES, ALS and CAPB can generate foam during mixing. Controlled agitation helps reduce excessive air incorporation.

3. Check the final product

Before commercial production, check parameters such as:

• Appearance
• Odour
• pH
• Viscosity
• Foam
• Stability

4. Make a small trial batch

The source recommends making small batches first because raw-material quality can affect the final product and the required quantities.
