laundry detergent is sodium benzenesulfonate, which has a good detergent effect and is very convenient to use, so it is very popular among people. Many washing powders on the market now have added some new ingredients, which have more and stronger washing functions. These main ingredients mainly include surfactants, builders, stabilizers, dispersants, whitening agents, flavors and enzymes. Synthetic laundry detergents are powdery (or granular) detergents, which are the most common synthetic detergents in life. This detergent is a mixture made of surfactant and additives to form a viscous slurry, and then produced by spray drying and agglomeration molding. Laundry detergent is composed of a variety of chemical components, and the main functions are surfactants, such as sodium alkylbenzenesulfonate, sodium alkylsulfonate, sodium fatty alcohol sulfate, fatty alcohol polyoxyethylene ether, copolymers of ethylene oxide and propylene oxide. Various chemical substances promote each other and make each other more ideal for washing and detergent effects. These surfactants can also be used directly as detergents, but the washing and detergent effect is not very ideal and the cost is high. Therefore, when preparing laundry detergent, some builders and auxiliary agents should be added to make the laundry detergent more complete and convenient for storage and use.

How to use laundry detergent to wash clothes
Although there are various laundry detergent, soap, etc., many people are still keen on laundry detergent for washing powder. The author personally believes that washing powder may wash clothes cleaner, but it is more irritating, so you need to pay attention to the details of use, use it correctly, and accumulate a little bit of subtle life knowledge, which may bring different excitement to our lives.
Steps:
1. It is best to soak the laundry detergent and clothes together, for about 15 to 30 minutes.
2. It is best to use warm water in winter to increase activity, but not exceed 40 degrees.
When the temperature is low and the water temperature is very low, the activity of washing clothes will be much lower. Therefore, appropriate use of warm water to wash clothes can better increase the activity of washing clothes. At the same time, we will not be too cold. Of course, we cannot use too hot water. First of all, too hot can easily burn clothes, and overheating will also damage the effect of washing clothes.
3. Just use an appropriate amount of laundry detergent, not excessive amounts.
In fact, this is not the case. The more clothes you wash, the more difficult it is to rinse. If the detergent left on the clothes is not rinsed clean and settled, it will easily cause the clothes to be stained with stains you don’t want to see, and even damage the clothes.
4. If you wash your hands, rinse them a few more times and finally rinse your hands more often.
We recommend that hand washing is better or use soap, which is not so irritating and protects our skin better. I don’t know if you have any experience. Every time you wash your clothes, your hands will feel dry, as if you are covered with a layer of things. No matter how you wash them, you will feel faintly. This is the damage to your skin.
5. The storage of laundry detergent needs to be dry and not damp.
In addition, when storing laundry, you must pay attention to a dry and ventilated environment and must not let it get damp. Once it gets damp or there is water, it will become one piece by one. Everyone has seen it, so it is basically useless. It is best to use plastic bottles to pack them, which are sealed at the same time, so that the storage is better.
6. If you choose laundry detergent, don’t pursue those with too much fragrance.
Now, in order to attract users, many merchants have added many other functions to washing clothes, such as fully automatic, full functions, and various fragrances. You should know that these are all for merchants. At the same time, too heavy fragrances have obviously added various chemical substances to the population, which are harmful to the human body. Don’t think that after washing clothes, a special fragrance will irritate the skin if worn on the body. Therefore, return to nature and be clean.
