How to Start Detergent Powder Making Business

How to Start Detergent Powder Making Business

Formed powders Washing when it appears is a qualitative leap in the field of detergent industry, which is a combination of organic and organic materials dissolved in water.

Classification of materials used in the manufacture of washing powder

1- surfactants

The surfactant molecule has a chemical structure that makes it able to dissolve in different phases and affect the surface tension at the interfaces between them.


A balance occurs between the polar section and the non-polar section of the active substance molecule called hydrophilic lipophilic balance. (HLB)

makes it able to change surface tension.

Types surfactants

 Surfactants are typically classified based on their polar head as the hydrophobic tails are often similar.

  • Anionic surfactants
  • Cationic surfactants
  • Nonionic surfactants
  • Amphoteric surfactants
Sulfonic acid is one of the most important surfactants used in washing powders.

1- bleaching material

Bleaching materials are added that depend on oxidation and release the effective oxygen that performs the bleaching process, the most important of which are:
Sodium perborate: It is one of the oxidative bleaching materials that are added to the detergent and releases the effective oxygen that performs the bleaching process, but it needs a high temperature to release the effective oxygen.

NaBO3.4H2 NaBO+ H2O2 + 3H2O

Sodium percarbonate: which was used instead of sodium perborate because it releases active oxygen at a low temperature.

C2H6Na4O12 or 2Na2CO3.3H2O2

3- bleaching agent

It lowers the temperature at which barborate decomposes, allowing oxygen to be released at lower temperatures. We mention TAED.

4- luminous material

Its role is to absorb part of the invisible daylight spectrum (in the ultraviolet field) and to carry out a fluorescence process that leads to the emission of blue light within the range 445-415 nm in order to compensate for the blue color absorbed by the white cloth.

5- Anti-dirt re-deposition

Where it forms a gel that surrounds the dirt and keeps it away from the tissue, preventing its re-positioning, such as CMC carboxymethyl cellulose.

6- chelated materials

It reduces the hardness of water caused by calcium and magnesium 
ions present in it, such as Sodium Tripolyphosphate (STPP).

chelated materials tripoly phosphate

7- building material

Such as sodium carbonate - silicates - sodium sulfate - table salt NaCl

8- Antifoam

To adjust the foam in the powder composition Or any other cleaner should add certain materials capable of destroying bubbles and the most important foam blockers:
Silicone antifoams are mixtures of PDMS or polydimethylsiloxane containing functional groups with finely dispersed fine silica grains.
These anhydrous mixtures are called Antifoam Compounds

Before we start talking about the method of making washing powder, we will briefly learn about the most important raw materials used, their properties and the benefit of adding them.

The most important raw materials used in the manufacture of detergent powder 

1- Sulfonic acid

Sulfonic acid is the most important active substance used in washing powders, and it determines the quality of the powder and the concentration of the active substance in cleaning.

2- Sodium silicate Na2SiO3

It is a weak alkaline used to modify sulfonic acid to obtain the active substance and is used to get a paste that is dried and get powdered The first before the other additions, which is called the semi-manufactured powder
Every 1 kg of sulfonic acid needs 1 kg of liquid silicate to complete the process
Silicates have been used in laundry detergents in general to give alkalinity to the detergent, which helps in swelling fibers and dirt, leading to easy removal from the fibers.
Silicates also have anti-corrosion properties.

3- Sodium carbonate Na2CO3

It is a chemical with high alkalinity, and alkaline materials were used in the detergent composition to increase the effectiveness of the washing process for two reasons, the first is that the high alkalinity deposits electrolytes that cause water hardness, and the second is that when the pH increases, the dirt particles and fibers carry negative charges, which helps in extracting soil and dirt particles, Sodium carbonate also improves the granular properties of detergent powder
(also known as washing soda, soda ash and soda crystals)

4- Sodium Percarbonate

 C2H6Na4O12 or 2Na2CO3.3H2O2
Sodium perborate and sodium percarbonate release oxygen into the medium, which in turn performs the bleaching process. 
However, the reactive capacity is closely related to the temperature, as sodium perborate requires a temperature higher than ํ 80 ° C, while the percarbonate releases it at temperatures less than ํ 30 ° C.
To enhance the bleaching action, he resorted to the addition of mediators that allow the release of oxygen at temperatures below 30 degrees Celsius. One of these mediators is TAED.

5- sodium tripoly phosphate stpp

Tripoly Sodium Phosphate is a prototype of the multifunctional booster in the detergent, and it has a large number of good properties. It has a great ability to complex calcium, magnesium and heavy metal ions. It also increases the wetting rate of the active substances. It is used as a source of alkalinity and has a buffering effect on the value of pH cleaning fluid, and helps break up the dirt crust from the fibers, and it is also a carrier of other detergent ingredients.

6- Sodium Sulfate Na2SO4

It is a cheap powder filler and has no cleaning effect.

7- Carboxymethyl Cellulose CMC

The process of removing stains from the surface of the fabric is an essential process, but it is important to push these stains away from the surface of the fabric and prevent them from re-setting.
CMC is considered one of the oldest and most famous anti-dirt agents on fabrics. CMC contributes to the formation of a gel around the dirt and carries it in a slimy form to the aqueous medium.

8- NaCl

It is a cheap filler used to reduce the cost of the product and according to the standard specifications, 2% of sodium chloride is allowed in the detergent.
Some manufacturers use, as a form of fraud, high levels of table salt, which may reach 20%, to reduce costs and increase profits, but they are harmful to fabric fabrics and automatic washing machines.

9- Antifoam

One of the most important is the silicone anti-foam that we talked about earlier.

10- Enhancers and perfumes

They are cosmetic additives to the shape and smell to become desirable by the consumer, such as colored sodium sulfate, and use distinctive perfumes to give a beautiful smell to the clothes after the washing process.

How to make detergent powder 

First - semi-factory washing powder industry

Important notice:
This method is considered the principle of manufacturing washing powder to obtain small household quantities, and it is not economically feasible for the manufacture of large quantities because it requires special high towers equipped with high pressure and temperatures to obtain homogeneous granules and large commercial quantities.

The method of work

  • We put 1 kg of sulfonic acid
  • we add 1 liter of distilled or filtered water.
  • we mix them well ti dissolve the sulfanic acid with water
  • We add 1 kg of liquid sodium silicate, which is a weak alkaline used to modify sulfonic acid

  • Every 1 kg of sulfonic acid needs 1 kg of liquid silicate to complete the process
  • We continue to stir well until we get a soft, cohesive dough
  • We add to the dough 1 kg of sodium sulfate, which is a building material and a filler for the powder
  • We continue to mix well until the ingredients of the dough are homogeneous
  • We add 250 ml of sodium hypochlorite , which is a minor substance used for bleaching and disinfection (commonly known in a dilute solution as bleach)
  • We add 0.5 kg of sodium carbonate Na2co3 (also known as washing soda, soda ash and soda crystals)
  • -Sodium carbonate is a high alkaline chemical used to increase the efficiency of the washing process
  • Continuing to stir, we will notice a stiffer and more cohesive dough
  • We add 0.5 kg of sodium tripoly phosphate stpp
  • It is a chelating substance that reduces the hardness of water resulting from the calcium and magnesium ions present in it
  • You can add 250 g of sodium percarbonate, which is a bleaching substance, or add it later after the dough has dried
  • Sodium percarbonate releases effective oxygen at low temperature
  • We note that the dough has become difficult to mix and has become tougher
  • Thus, we have completed the first stage in the manufacture of washing powder
  • We leave the dough after it has been extended in a room with a high temperature or expose it to the heat of the sun for several days
  • We sift it to get medium-sized granules
  • We have obtained the final powder and it is called the semi-
  • finished powderAnd we will continue in the next video, starting with the semi-manufactured powder, how to get ready-made powder for sale with good commercial specifications

Second - the manufacture of washing powder ready for sale

Which is made from the powder half of the factory that has been processed.
The article will be updated and the method added later with the accompanying video.
