The effect of washing eyes with light salt water (how to do it with light salt water)

Hello, now let me answer the above questions. I believe many friends still don't know the effect of washing eyes with light salt water. Let's take a look now!

1, dilute salt water is brewed with 100 ml distilled water and about one gram of salt.

2. It has several uses in daily life: one is to supplement the water and sodium lost by the body after sweating; Second, replenish the water and salt lost in the intestine after diarrhea and maintain electrolyte balance; Third, gargling with light salt water can remove bacteria in the mouth and reduce redness and swelling caused by oropharyngeal inflammation.

3, production method: add a little salt to warm water, mix well, sing a slightly salty taste.

4. Extended information:

At present, it is common to spray pesticides on vegetables and fruits.

5. Feng Shuangqing introduced that pesticides are mainly divided into water-soluble and fat-soluble, which are mainly selected according to crop diseases and long worms.

6. Water-soluble pesticides can be dissolved and absorbed by cleaning with clear water, but it has little effect on fat-soluble pesticides.

7. Fat-soluble pesticides, such as organophosphorus, are insoluble in water. You can add some alkali or use a fruit and vegetable cleaner.

8. Why can alkaline water clean pesticides? She explained that fat-soluble pesticides can be dissolved in alkaline water and then washed with clear water.

9. However, while dissolving pesticide residues, alkali may decompose nutrients in fruits and vegetables.

10, Zhao Bin said that lipids in vegetables and fruits, such as some vitamins and other nutrients, will decompose under alkaline conditions and become water-soluble substances, which will be washed away by clean water, resulting in partial nutrient loss.

1 1. Comparatively speaking, it is difficult to remove pesticide residues by adding vinegar to salt water or water.

12, Feng Shuangqing told reporters that the main function of salt water is sterilization, such as raw vegetables or fruits, which can be soaked in salt water after cleaning.

13. From the point of view of changing the solubility of water, the solubility of water is basically unchanged after adding salt and a small amount of vinegar, and lipid substances are still insoluble.

14, in addition to the above cleaning methods, a wide variety of fruit and vegetable cleaning agents on the market are gradually becoming one of the ways to remove pesticide residues.

15, Feng Shuangqing said that these cleaning agents mainly become foaming agents and surfactants, which are alkaline and can increase water solubility.

16, Zhao Bin explained that one end of surfactant is lipophilic and the other end is hydrophilic, which can not only dissolve water-soluble pesticides, but also remove fat-soluble pesticides.

17. For the problem that some citizens can't master the amount of cleaning agent, it is forbidden to use too much cleaning agent. On the one hand, it may be harmful to people's health because it is not clean.

18 On the other hand, the principle of cleaning agent is similar to that of washing powder, too much will lead to the change of cleaning principle and the decrease of decontamination ability.

19, "Generally speaking, a few drops are enough.

In addition, when you buy a detergent, you can't judge whether it has a taste. Some detergents have a fruity smell, and some additives may be added, which is harmful to health.
