What are the main ingredients of laundry detergent?

Laundry detergent is generally a mixture of various ingredients, among which the substance that plays the main role in washing and detergency is surfactant.

In addition, it also contains some substances that can enhance and improve the various properties of laundry detergent, and these substances are called additives. The type and amount of additives added vary depending on the purpose of the detergent and the nature of the dirt and fabric. In order to reduce costs and help molding, laundry detergents are also added with fillers, such as sodium sulfate. Wait.

There are now traditional laundry detergents, oxygenated laundry detergents, and laundry detergents on the market.

Oxygenated laundry detergent is now more popular, it is generally larger than ordinary laundry detergent particles called oxygen granules Its main ingredient is sodium peroxide, after sodium peroxide carbonate enters the body and comes into contact with body fluids, it will be decomposed into hydrogen peroxide, carbonate and sodium ions, which are naturally present in the human body. Since hydrogen peroxide has a strong ability to degrade in blood and tissues, it is unlikely that hydrogen peroxide will spread throughout the body. Its complete working principle is:

Oxygen particles quickly dissolve and diffuse when exposed to water, and the oxygen atoms released move violently, penetrate deep into the fabric fiber, strongly disintegrate the stains, take away the stains in the fabric fiber, and restore the clean state, which is the washing principle of the popular aerobic washing now. This oxygenated laundry detergent is generally used in warm water to achieve a stronger decontamination effect.

Traditional laundry detergent and laundry detergent work similarly, mainly relying on surfactants and some additives to decontaminate and clean clothes, because the composition of the two is almost the same, both are mainly composed of surfactants and additives, but laundry detergent is added, chelating agent, solubilizer, defoamer, softener, preservative, but because the laundry detergent contains a large amount of water, enzymes (adding enzymes can enhance the detergency) are unstable in the water, resulting in relatively mild detergency, slightly inferior to laundry detergent.

2. How to tell if the clothes are clean:

There is no real standard for this estimate, which is not scientifically experimental. I generally judge from the color, smell, and feel, when we wash the laundry, we are more to the stains, you can check whether the original stains return to the original color after washing, and then smell it, which I think is very heavy, if the clothes have no odor, the clothes are basically clean, because there are bacteria, there are invisible stains that will produce the smell, especially in summer. However, if you use scented laundry detergent, it will be difficult to distinguish whether the real odor of the clothes has been removed or not, because the fragrance of the laundry detergent will cover the smell on the clothes.

Touching it with your hand again, except for the feeling of the fabric of the clothes themselves, it is judged that it is really washed without being abnormally slippery.

3. How to wash off stubborn stains:

Now the main popular is oxygen particle laundry, I will introduce this how to get stubborn stains, relatively simple: soak the oxygen particles in 34-60 degrees of warm water, and then soak the clothes into it for about 1 hour, if the stains are more stubborn, you can soak for a long time, and then it is easy to remove the stains under scrubbing, mainly for blood stains, milk stains, fruit juice, cola stains, red wine stains, oil stains, other types of stains I have not tried, not very sure, you can try it yourself. It can also be washed together with traditional laundry detergent and some oxygen particles, which can enhance the decontamination effect of ordinary laundry detergent.

When oxygenated particles remove stains, it is mainly the oxygen bubbles released by the dissolution of sodium peroxylate that penetrate deep into the clothing fibers to carry away the stains.

The main ingredients of laundry detergent are anionic surfactants, sodium alkylbenzene sulfonate, a small amount of nonionic surfactants, plus some additives, phosphate, silicate, yuanming powder, fluorescent agent, enzyme, etc., which are made by mixing, spraying and other processes, and now most of them use 4A fluorite instead of phosphate.

Laundry detergent is an alkaline synthetic detergent, which is a chemical agent used for washing clothes, which was first invented by Hangao in Germany in 1907 with borate and silicate as the main raw materials. After the 40s of the 20th century, with the development of the chemical industry, people used the chemical substance extracted from petroleum - sodium tetrapolypropylene benzene sulfonate to make detergents with better performance than soap.

The main ingredient of laundry detergent is sodium alkylbenzene sulfonate, which has a good detergent effect and is very convenient to use, so it is deeply loved by people. However, laundry detergent has a certain toxicity, and even if a small amount of laundry detergent enters the body, it will have a strong inhibitory effect on the activity of various enzymes in the human body. Laundry detergent invades the human body, destroys the cell membrane of red blood cells in the blood circulation, causes hemolysis, invades the thymus, damages the thymus, and leads to a decrease in the body's resistance.

Laundry detergent can also cause diarrhea, weight loss, spleen atrophy, cirrhosis, etc.

The main ingredients of a better laundry detergent are: fabric fiber antiscalant, anionic surfactant, nonionic surfactant, water softener, dirt suspension, enzyme, fluorescent agent and fragrance, etc.; Poor laundry detergents often contain harmful ingredients such as phosphorus, aluminum, and alkali. The role of surfactant in laundry detergent is to make laundry detergent soluble, emulsify, soak, clean, sterilize, soften, foam, and prevent static electricity of clothes.

Synthetic surfactants have long been found to make hands thicker***, and now they are regarded as a major public nuisance to the environment. In addition, phosphorus, aluminum alkali, especially phosphorus has been banned in some developed countries in laundry detergent, but many chemical plants in China are still producing this kind of products, especially some foreign-funded enterprises, and then their own local products can not have these harmful substances, and in China, it is the law is not perfect, people's environmental awareness is not strong, boldly add these harmful substances.
