Chemical problems with detergents

5. Removal of curry oil stains.

The way to wash off curry oil stains on clothes is to first moisten the curry oil stains on the clothes with water, then scrub them with warm glycerin, and finally wash them with water. If the clothing is made of cotton and linen, it can be brushed with 10% ammonia solution.

If the clothing is made of silk and wool, it can be brushed with 10% dilute acetic acid aqueous solution, and finally rinsed with water. Curry oil stains on white clothes can be scrubbed with a 5% sodium hypochlorite aqueous solution, then washed with detergent, and finally rinsed with clean water.

Detergent is a specially formulated product that is used for cleaning through the washing process. The main components are usually composed of surfactants, detergents and additives. There are many types of detergents, which can be divided into heavy scale detergents and light scale detergents according to the type of dirt removed; According to the shape of the product, it can be divided into powder, block, paste, slurry and liquid and other forms.

Common detergents in life include laundry detergent, soap, laundry detergent, soap powder, color bleach, etc. <

Detergent is a product that is specially formulated for cleaning through a washing process. The main components are usually composed of surfactants, detergents and additives. There are many types of detergents, which can be divided into heavy scale detergents and light scale detergents according to the type of dirt removed; According to the shape of the product, it can be divided into powder, block, paste, slurry and liquid and other forms. According to the scope of use, it can be divided into civil detergents and industrial detergents.

Common detergents in life include laundry detergent, soap, laundry detergent, soap powder, color bleach, etc. The main component of detergent is surfactant, which is an organic compound with two parts of the molecular structure, hydrophilic and lipophilic. Generally, according to whether surfactants can be decomposed into ions in aqueous solution, they are divided into two categories: ionic surfactants and non-ionic surfactants.

Ionic surfactants can be divided into three types: cationic surfactants, anionic surfactants and zwitterionic surfactants. Practice has proved that there are only anionic surfactants and non-ionic surfactants in the washing of fabrics, which can play a positive and effective role in fabric decontamination. Therefore, these two surfactants have become the main materials for laundry detergents.

The detergent should have good wettability, permeability, emulsification, dispersion, solubilization, foaming and defoaming properties, and the combination of these properties is the washing performance of the detergent.

Summary. Detergents are a class of chemicals used for washing, decontamination, and are commonly used to wash and disinfect items such as clothing, dishes, floors, furniture, cars, etc. Detergents can be classified into various types depending on their use and composition, such as:

1.Laundry detergent: used for washing clothes, including laundry detergent, laundry detergent, laundry soap, etc.

2.Household cleaners: used to clean household items, including dish soap, toilet fluid, floor cleaners, etc.

3.Personal care products: used to cleanse the body, hair, etc., including shower gels, shampoos, toothpaste, etc.

4.Industrial cleaners: used to clean machinery and equipment, vehicles, etc., including decontamination powders, car cleaners, etc.

Detergent is a class of chemicals used for cleaning and decontamination, and is usually used to clean and disinfect clothing, tableware, floor cleaning boards, furniture, cars and other items. According to its different uses and ingredients, the precursor can be divided into various types, such as: 1

Laundry detergent: used for washing clothes, including laundry detergent, laundry detergent, laundry soap, etc. 2.

Household cleaners: used to clean household items, including dish soap, toilet fluid, floor cleaners, etc. 3.

Personal care products: used to cleanse the body, hair, etc., including shower gels, shampoos, toothpaste, etc. 4.

Industrial cleaners: used to clean machinery and equipment, vehicles, etc., including decontamination powders, car cleaners, etc.

The main components of detergent include surfactants, additives, buffers, preservatives, etc., among which surfactants are the key components of detergents, and their main role is to destroy the surface tension of grease and dirt, so that they are dispersed and washed away by water.

Detergents are mainly specially formulated products for cleaning objects during the washing process. It has the functions of cleaning, sterilization and grease removal.

Its main components are usually composed of surfactants, detergents and additives. There are many types of detergents, and according to the type of dirt removed, they can be divided into heavy scale detergents and light scale detergents. According to the shape of the product, it can be divided into powder, block, paste, slurry and liquid and other forms.

In the washing of fabrics, there are only anionic surfactants and non-ionic surfactants, which can play a positive and effective role in the decontamination of fabrics. Therefore, these two surfactants have become the main materials of laundry detergents. Detergents should have good wettability, permeability, emulsification, dispersion, solubilization, foaming and defoaming properties.

The combination of these properties is the washing performance of imitation powder, detergent.

There are many types of detergents, which can be basically divided into soaps, synthetic Bichang's laundry detergents, liquid detergents, solid detergents and paste detergents. Laundry detergent is alkaline but cost-effective, laundry detergent is an alkaline synthetic detergent with strong detergency, good solubility and easy to use, and is better in terms of hard water resistance and rich foam. At the same time, it is cheaper and belongs to the cost-effective laundry cleaner.

Using laundry detergent for a long time will make clothes gray and yellow, and white clothes are the most noticeable.

Zhang Huatao, deputy secretary-general of the China Detergent Association, said that laundry detergent is more suitable for washing cotton, linen, chemical fiber and blended fabrics. It is not suitable for washing wool, silk and other clothes. Because wool, silk and other clothes contain protein, while laundry detergent is alkaline, it will damage clothes.

Laundry detergent has a better washing effect in warm water than cold water, dissolves evenly in warm water, and surfactants can play a greater role, and the water temperature is 30 to 60.
