Shampoo Industry (Part II) | Making 100 kg shampoo for all hair types



We talked in the first part about hair types , the causes of dandruff and ways Disposal , the most important specifications required for the shampoo industry and we will continue to talk in this article about the raw materials involved in the shampoo industry and the role of each of them, and the method of making a mixture of 100 kg of shampoo for all hair types with an explanatory video of the mixing method in detail.


Classification of substances involved in the shampoo industry:

I- Active materials and foam boosters:

They are the basic building materials in shampoo and they give the cleaning ability of the shampoo and enhance the amount of foam in the product, and the higher the percentage, the higher the viscosity and the smallest amount of thickeners used such as sodium chlorine and the most important:

sodium lauryl ether sulfate SLES :

  • It is a surfactant, ionic substance
  • With a transparent viscous texture
  • Commercially, its concentration is 70%.
  • It is a detergent and foam booster
  • High quality sodium lauryl ether sulfate is preferred for excellent results.


DEA Cocoamide diethanolamine

  • It is a surfactant, iridescent agent from coconut derivatives
  • With a sticky water texture, yellowish brown
  • His concentration is 85%.
  • Reinforced and excellent foam stabilizer - wife lifter


Cocamidopropyl betaine

  • Surfactant compound
  • Yellowish liquid with light viscosity
  • Excellent foam booster
  • Its commercial focus is 25%.


Unloading materials for shipments

These are substances that pull out negative charges of the hair and thus prevent its tangle and difficulty styling it after bathing, such as:


 CETYL TRIMETHYL AMMONIUM CHLORIDE

It is one of the solutions of the ammonium alkyl derivatives and is called dequart . A transparent or slightly yellowish water liquid that produces bubbles when moving and thus we can distinguish it from glycerin or simasol (amniocentesis) is a hair conditioning agent where it has the structure of active chemicals with a positive head that reacts with negative charges on the hair and thus helps to make the hair with a smooth surface and prevent tangles.


glycerin C3H8O3

A 100% water-based moisturizer that is classified as an air-conditioned substance that helps styling hair


Water desalination and hardness:

It relieves water hardness in order not to affect foam and product purity and transparency such as:


1- EDTA :

Ethylenediamintetraacetic Acid , a poly-amino carboxyl acid, a solid dissolved substance in water for its color, is a claw ingesting agent where it retains mineral ions and relieves water difficulty.


2- Citric acid:

Used to modify ph on 5.5

And it has a role in the transparency of the final product as it reduces the hardness of water.


Opacity materials:

These are substances that give shampoo a creamy or pearl shape such as:


Ethylene Glycol Distarate )

It is a superficially effective non-ensove substance that moisturizes and emulsifies the shampoo and its milky pearl appearance.

It has many types according to the additions of the manufacturer, and the most important manufacturers of it stepan American, and the German company BASEF.

And it has a white cream shape.


V. Anti-dandruff:

They are active substances against germs, including:


(Salicylic acid C7H6O3), a weak carboxyl acid in powder form White.


Climpazole: an antifungal agent used in the treatment of dandruff, and is applied at no more than 0.1% in shampoo, which is powder White with a melt in the water.


Fat removal substances:

Like propylene glycol and ethanol.


Seventh - Thickeners:

They are substances that raise the texture of shampoo such as sodium chlorinated salt or magnesium sulfate, preferably increasing the proportion of active substances to raise the texture and using the least amount of thickeners where it has a negative effect on the foam of the product and causes damage to the hair.


Preservatives:

To protect the product from rot and maintain it for as long as possible during storage such as parmetol, even ethanol and balsamic water also play the role of preservatives of the product.


9- Hair tonics and natural oils:

Vitamins can be used in the shampoo industry in very small proportions such as: vitamin B5 (pro vitamin or di panthinol), which strengthens hair follicles . Natural oils can be used in the manufacture of natural shampoos such as olive oil, castor oil or aloe vera oil.... Etc


X- Cosmetic additions:

The fragrance and pigment that give the shampoo a shape and appearance acceptable to the consumer, and the fragrance must be chosen carefully and should be dedicated to the shampoo so as not to interact with other substances used . Also, pigment should not affect or dye hair and is used in small quantities.


The materials required to make 100 kg shampoo for all hair types:

  • Water 70 kg
  • Citric acid 50 gr
  • sodium lauryl ether sulfate SLES N70 14 kg
  • DEA Cocoamide diethanolamine 3 kg
  • CETYL TRIMETHYL AMMONIUM CHLORIDE 2 kg
  • Glycerin 0.5 kg
  • Propylene glycol from 100 to 0.5 kg
  • Climbazole 100 g
  • Ethylene Glycol Distarate 700 g
  • Cocamidopropyl betaine 5 kg
  • Preservative (Parmitol) 100 to 150 gr
  • pigment of 2 g
  • Perfume from 800 to 1 kg or according to desire, type and strength of fragrance.


How it works

  • Fill the mixing barrel 70 kg filtered water or plain water added 200g EDTA 
  • add 50g citric acid which is enough to get PH = 5.5 and to make sure ph measure it at a later stage or after the end of the mixture
  •  we add 14 kg of sodium lauryl ether sulfate and continue mixing until it is fully dissolved.
  • Add 3kg of Cocoamide diethanolamine and continue stirring well.
  • Add CETYL TRIMETHYL AMMONIUM CHLORIDE, then glycerin, then propylene glycol, then climbazol, then the Cocamidopropyl betaine , then the preservative, respectively, and stir well between the material and the other.
  • Make sure the PH value well and then stop mixing and leave the mixture until the next day.
  • After 24 hours, add the right pigment and fragrance and then gradually add the saturated saline solution until the desired viscosity is reached.
