How is laundry detergent made? How to use laundry detergent

Laundry detergent is not a single substance, but a compound of multiple ingredients.

1. Surfactant: sodium alkylbenzene sulfonate is the main one, but modern new laundry detergents do not only use this active agent, but a complex of a variety of anionic and nonionic surfactants.

2. Alkali agent: sodium carbonate (soda ash), sodium silicate (bubble alkali), sodium perborate, etc.

3. Water softener: the traditional one is sodium tripolyphosphate, and the washing and decontamination complexed metal ion effect is first-class. However, it is not good for the environment and will cause eutrophication of water bodies, so in recent years, there is a tendency to be replaced by 4A zeolite.

However, the stain removal ability of zeolite-free laundry detergent is definitely not comparable to that of phosphorus-containing laundry detergent. Daqingshu's original reply.

4. Anti-redeposition agent: carboxymethyl cellulose or polyethylene birolidone.

5. Fluorescent brightener.

6. Alkaline protease.

7. Flavor.

Laundry detergent is an alkaline synthetic detergent, the main ingredient of laundry detergent is anionic surfactant: sodium alkylbenzene sulfonate, a small amount of nonionic surfactant, plus some additives, phosphate, silicate, yuanming powder, fluorescent agent, enzyme, etc. It is made by mixing, powder spraying and other processes.

Now most of them use 4a fluorite instead of phosphate. The method is somewhat complicated, it is recommended to buy it directly, and it is not expensive

The process is like making fertilizer in industry. Ah, which one to use, the tower to know.

I don't know, the legendary chemical.

When washing clothes, put the laundry detergent into the basin, add water to mix, and then put the clothes in the basin to soak, generally soak for about 15-30 minutes, and then wash the clothes by hand after soaking. The more laundry detergent you have, the easier it is to settle on your clothes, causing stains and even damaging your clothes.

Laundry detergent is a chemical agent used to wash clothes, and it is an alkaline synthetic detergent.

Laundry detergent can show a good decontamination effect in various water qualities such as well water, river water, tap water, spring water, and even seawater, and is widely used in all kinds of fabrics.

When cleaning and washing, you should put in laundry detergent first, laundry detergent is a powder, not easy to dissolve, first dissolve with water in order to better exert its effect.

1. The concentration of laundry detergent is at one time, and the washing and decontamination ability is the strongest, that is, adding 5-10 grams of laundry detergent to a basin of water is enough. If you use concentrated powder, you can use more than half. Excessive laundry detergent will increase the alkalinity of the solution and damage the clothing fibers.

In addition, a large amount of laundry detergent is attached to the clothes, and there is a lot of foam, which makes rinsing laborious, water-consuming, and time-consuming, wasting laundry detergent.

2. Silk weaving and sweaters, woolen clothes can not use laundry detergent, soap powder and other substances with active enzymes, if you feel that the soap is harder, you can use professional silk wool net to wash the above clothes.

3. When using laundry detergent, water temperature is also the key. You can dissolve the laundry detergent in warm water to restore the active enzymes, then add water below 30 degrees, soak the clothes for 10-15 minutes, and rub. In this way, the effect of laundry is better.
