   Shampoo is an indispensable hair care product in our daily life. But do you know what the main components are in it? Would you like to use a shampoo you make yourself? Then let's...

togetherHandmade DIYIt's a shampoo from your own brand!

Experimental focus: Understanding the simple principle of preparing shampoo.

The purpose of the experiment: 1. To understand the main components of shampoo 2. To know the role of each component in shampoo.

Experimental Cognition

 Dodecanol sulfate: abbreviated as K12, a sodium-based anionic surfactant with excellent wetting, emulsifying, and cleaning foam performance. Ammonium chloride is a colorless crystalline or white crystalline powder; it has no odor.

Salty and cool: has a tendency to attract moisture. This product dissolves easily in water and can be added to shampoo in moderation to make the shampoo thicker and feel better.

  Thickening agent: Ammonium chloride is a hydrophilic polymer compound, also known as a gelling agent. When used in food, it is also known as a thickener or food glue. It can increase the viscosity of the system, allowing the system to maintain an even and stable suspension state.

Or milky state, or form a gel. Widely used in food, coatings, adhesives, cosmetics, detergents, dyeing and printing, rubber, medicine and other fields.

 Pigment and Flavor: Pigment is an additive that to some extent changes the original color of a substance. Flavor is a concentrated essential oil that mimics the aroma of fruits and natural spices, synthesized by humans. Pigment and flavor are used together.

So, it can be divided into two types: natural and synthetic.

Experimental steps:

 1. Experiment Preparation: Understand the experiment equipment: plastic cups, ammonium chloride, thickening agent, K12, pigment, flavor, small sticks, small spoons.

 2. Pour K12 (sodium dodecyl sulfate) into a plastic cup, add an appropriate amount of warm water, and stir well with a stick until completely dissolved, then add ammonium chloride and stir well.

 3. To increase the viscosity of the shampoo, add an appropriate amount of thickener and stir it (the pigment and thickener are mixed in a single packaging bag), then add the fragrance, and stir it evenly with a small stick. The homemade shampoo

It's done.

 Tip: When stirring the liquid, stir in the same direction, do not use excessive force to avoid spilling the liquid. Do not taste the components or solutions of the experiment.

Knowledge Expansion:

 The ancient people used soapwort or pigling to wash their hair. Only those with more wealth would use pigling, which contains some spices and leaves a strong fragrance after use. Ordinary people would use soapwort to wash their hair.

Sage is a natural plant, which is non-toxic to the human body and can be used to wash hair and other delicate parts. Hair washed with sage water is clean, black and shiny, with a slight fragrance; the color of the clothes washed does not fade, which is very popular among the people.

Like. Washing the hair also uses rice water, which is called 'Pan'. After checking the information, I found that the ancient people are much more hygienic than we think. During the Qin and Han dynasties, it has formed a three-day hair washing and five-day bathing system.

Habit. The one-day holiday given by the government every five days is also known as 'Xumi'.

Do you know?

 In the modern market, shampoo comes in a variety of forms, and there are a few points to help you determine the quality of shampoo.

 1. Look at the packaging, good shampoo packaging is very exquisite with good materials, the color is very accurate and soft, the interface is tight without cracks, and the printing is clear.

 2. Smell the fragrance, the better the shampoo, the lighter the scent and closer to the natural scent, and it lasts long after use;

 3. Look at the foam. Good shampoos are easy to lather, and the finer the foam, the better.

 4. Examine the shampoo's paste body to see if it is fine. The better the shampoo, the finer the paste body, with no lumps and a strong cohesive force. However, there are also a very small number of shampoos that contain plant or biological ingredients, which can cause an inconsistent effect.

However, these ingredients are very beneficial for hair.

 5. Extremely easy to rinse clean, and there is no sticky feeling; 6. After use, the hair feels light, natural and smooth, without the phenomenon of combing.

Experiment Report:

 Use yourselfHandmade DIY Science ProjectsIs using the shampoo for hand washing and hair washing the same as using the shampoo purchased from home? Can you also make your own DIY shampoo at home?

Choosing a loud and unique name for yourself, isn't that cool!

  After completing the DIY project, let's think about whether using pure water in the experiment can extend the shelf life of shampoo?
