One of the main factors influencing the purchase of shampoo is its color and smell. To improve these properties, manufacturers add aromatic oils that are approved by the government. Other special additives can have a similar effect. Natural ingredients such as plant extracts, natural oils, proteins and vitamins all have special properties And help the effectiveness of shampoos. Additives such as peritoneum are used together for dandruff. Other additives are dyes that can color the hair. Once the shampoo formula is created, it is tested to ensure that its quality changes as little as possible over time. This type of test is called a stability test and is primarily used to detect physical changes in properties such as color, odor, and stiffness. These tests can also provide information about other changes, such as microbial contamination and functional differences. This test is done to make sure that the shampoo bottle that is placed on the store shelves has the same function as the bottle that is produced in the laboratory. The production process can be divided into two stages. The first step is to make a large batch of shampoos and then pack this in bottles.
Combination
- Large batches of shampoo are made in the factory in a place designed to make shampoo. Here the workers follow the instructions of the formula. The raw materials are usually in the form of 55 gallon cylindrical containers or 23 kg bags, which Shipped to the place of combination. They are poured into the tank and mixed thoroughly.
- Depending on the formula, shampoo batches are heated and cooled as needed To help raw materials combine faster. Some raw materials, such as water or cleaning raw materials, are pumped directly into the tank. These materials are added simply by pressing a button on computer controls. These controls also adjust the mixing speed and the amount of heating and cooling. Depending on the size and type of shampoo, making a batch of 3,000 gallons can take from one to four hours.
Quality Control
- Once all the ingredients are added to a batch, A sample is sent to the Quality Control Laboratory (QC) for testing. Physical properties are checked to ensure that they have the specifications listed in the formula instructions. Quality control group, tests such as solution pH determination, Performs viscosity testing and appearance and odor evaluation. You can also check the amount of detergent in the formula and whether there is enough preservative.
- If a bunch of shampoos are found that are out of order, The settings are done again. For example, acids or bases can be added to adjust the pH Or salt can be added to change the viscosity. The color can also be adjusted by adding more color.
- After a batch of shampoos were approved in the quality control department, It is pumped out of the main handle tank and into a holding tank. This is where shampoos can be stored to prepare for filling lines. Shampoos are pumped from the holding tank to the filler, which consists of a carousel of filler piston heads. After ensuring the non-microbial contamination of the product and matching the results of physical and chemical tests with standard values, The shampoo product, which was made in the first stage, is transferred from the manufacturing tanks to storage tanks. The packaging part of the production hall is completely separate from the construction part
Fill bottels
- At the beginning of the filling line, the empty bottles are placed in a large bucket called a funnel. Here, the bottles are physically (by hand) manipulated to stay upright. They are then transported with a conveyor belt to the filling carousel, which contains shampoo.
- The filling carousel is made of a group of calibrated piston heads To transfer exactly the right amount of shampoo to the bottles. (Otherwise, for example, some bottles will overflow.) When the bottles move from this part of the filling line, they are filled with shampoo.
- From here the bottles move towards the closing machine. This is very similar to a box containing empty bottles, The lids are placed in a funnel and then aligned with each other. When the bottles move, the doors are placed on them. The bottles are tightly twisted .
