Because of the wide range of detergents, it is not easy to generalize. According to our understanding of the role of detergents before the experiment, we divided them into two categories. The former (to achieve the purpose of hygiene ~) is familiar to everyone because it is commonly used. We also mainly introduce this washing.

Types of detergents

There are many kinds of detergents, and there are many standards for their classification. According to different standards, it can be roughly divided into the following categories.

1, divided by washing machine: hand washing detergent, machine washing detergent.

2, according to the state: granular detergent, liquid detergent, emulsion detergent, block detergent.

3. According to washing objects: fabric detergent, toilet detergent, tableware detergent, wallpaper, furniture, floor and carpet detergent, car detergent, plastic and leather product detergent, bath detergent.

4. Special function detergents: metal detergents, beauty detergents, weight-loss detergents, household appliances detergents, etc.

Types of household detergents: household detergents are chlorine-containing detergents with sodium hypochlorite as the main component, which are used for sterilization and disinfection, such as detergent, detergent and bleach. The second kind of household detergent is an acid-containing detergent with hydrochloric acid as the main component, which is used for cleaning and decontamination, such as deodorant, pipeline cleaner, kitchen cleaner and so on. Because of the different compositions and properties of the two chemical products, once they are used together, harmful chlorine gas may be produced.

When the chlorine content in the air reaches 15ppm, people's eyes and respiratory tract will feel pain; When it reaches 50ppm, it will cause chest pain, cough, expectoration and even hemoptysis; When it reaches 100ppm, it will cause dyspnea, blood pressure drop, even shock and suffocation, leading to death. There have also been accidents in foreign countries where two kinds of household detergents were mixed to cause death. When using these two household detergents, Ms. Wang did not read the instructions clearly and did not use them according to the instructions, which caused the above situation. ?

By the way, be careful with the enzyme washing powder. Enzymatic washing powder is a kind of washing powder containing protease, which can decompose the protein component in the dirt of clothes, with strong detergency and high cleanliness, saving time and effort. However, it will also have harmful effects on the human body. If the skin is in direct contact with protease, it will decompose human protein and damage the skin. For normal people, this kind of damage is extremely slight and almost imperceptible. For people with skin diseases and allergies, using enzyme-added washing powder or wearing clothes washed by this detergent but not bleached may aggravate the original skin diseases or cause some allergies. Such as allergic skin rash's disease, eczema, allergic edema of nasal cavity and pharynx mucosa or allergic asthma attack. Therefore, when using enzyme-added washing powder, we should try to avoid soaking the skin in high concentration solution for too long; People with skin diseases and allergies should try not to use enzyme-added washing powder; Rinse thoroughly when washing clothes.

The main component of household detergent is surfactant, which has a strong washing effect and can effectively remove oil stains and pesticides from dishes, chopsticks, fruits and vegetables. It's usually safe, but it can't be mixed with toilet cleaner (commonly known as "red water") because toilet cleaner is blended with hydrochloric acid and has a high chlorine content. When it interacts with detergent, it will produce toxic gas-chlorine, which is easy to poison people.

Wash melons and fruits with detergent. Is the soaking time as long as possible? Wang Ping thinks that the soaking time depends on different skin conditions. For example, if the skin is not smooth, such as washing strawberries, it can be soaked for more than ten seconds, otherwise the detergent will remain; Wash vegetables and soak for 30 seconds. In order to remove the residual detergent to the maximum extent, you should wash it with tap water at least twice.

Finally, remind housewives that because the detergent has strong degreasing ability, it will cause skin wrinkles when used in dry season, so it is necessary to apply skin care products in time after use.
