Key Chemical Components in Laundry Detergent
Laundry detergent relies on several essential chemical compounds that contribute to cleaning clothes effectively. The main components are:
- Sulfonic Acid: Acts as a powerful surfactant and enhances foam formation.
- Sodium Silicate: Used to adjust acidity and improve the powder’s texture.
- Sodium Carbonate (Washing Soda): Removes grease and aids in deep cleaning.
- Sodium Sulfate: Acts as a filler, helps distribute ingredients, and adjusts acidity.
- Sodium Tripolyphosphate (STPP): Enhances cleaning effectiveness and prevents caking.
- Sodium Metasilicate: A powerful cleaner, but requires careful handling.
- Sodium Perborate (Borax): Removes stains and acts as a bleaching agent.
- Blankfor (Optical Brightener): Maintains the brightness of clothes’ colors.
- Concentrated Chlorine: An effective disinfectant for killing germs.
- Colored Granules: Give the powder an attractive appearance.
- Fragrance: Adds a fresh scent to the clothes.

- 7.5 kg Sodium Carbonate
- 20 kg Sodium Sulfate
- 7.5 kg Sodium Tripolyphosphate
- 2.5 kg Sodium Metasilicate
- 1 kg Sodium Perborate
- 75 grams Blankfor
- 750 grams Concentrated Chlorine
- 1 kg Colored Granules
- Fragrance (as desired)
- 125 grams Anti-foaming agent (for automatic machines)
Required Tools and Safety Gear
Safety First!
Handling these chemicals requires strict safety measures. Always work in a well-ventilated area and use the proper Personal Protective Equipment (PPE).
Personal Protective Equipment (PPE)
- Safety Goggles
- Rubber Gloves
- Face Mask
- Plastic Apron
Manufacturing Tools
- Large plastic mixing containers
- Wooden or plastic stirring paddle
- A precise scale for measuring ingredients
Step-by-Step Manufacturing Process (50 kg Batch)
Step 1: Preparing the Liquid Mixture
- In a large container, add 5 kg of sulfonic acid to 5 liters of water.
- Slowly add 5 kg of liquid sodium silicate while stirring to neutralize the acid.
- Add 750 grams of concentrated chlorine and continue mixing.
Step 2: Preparing the Paste
- Gradually add 20 kg of sodium sulfate to the liquid mixture, stirring continuously until a thick paste forms.
- Spread the paste in a thin layer and let it dry completely, either under the sun or using an industrial dryer.
Step 3: Turning the Paste into Powder
- Once the paste is dry and hard, grind it into a fine powder. Sieve the powder to ensure a uniform consistency.
- In a large, dry container, combine the ground powder with all the remaining dry ingredients:
- 7.5 kg Sodium Carbonate
- 7.5 kg Sodium Tripolyphosphate
- 2.5 kg Sodium Metasilicate
- 1 kg Sodium Perborate
- 75 grams Blankfor
- 1 kg Colored Granules
- Fragrance (as desired)
- Mix thoroughly until all components are evenly distributed.
Step 4: Final Product Preparation
- For a low-foam version suitable for automatic washing machines, add 125 grams of anti-foaming agent and mix well.
- Store the final powder in airtight, moisture-proof containers.
