Detergent is an indispensable daily necessities for everyone. As we pay more and more attention to safety, many people will be concerned about the safety, environmental protection and residue of detergent. So what are the safety hazards of washing dishes with detergent? How to safely use detergent to wash dishes?

Surfactant is the key to degreasing detergent.

If you look at the main components of detergent carefully, you will find a component called "surfactant". Detergent can remove oil stains without the help of surfactants.

Surfactant is an organic molecule, and its special structure of hydrophilic at one end and lipophilic at the other makes it soluble in water and can disintegrate oil stains.

specifically, the decontamination principle of detergent is to dissolve, emulsify, disperse and suspend the dirt in water medium by surfactant, and then separate the dirt from the surface of tableware by rinsing with clear water, so as to achieve the effect of cleaning tableware.

Of course, besides surfactants, detergent also contains other ingredients, such as water, additives, essence, etc. Some detergents also contain sterilization and disinfection ingredients, which can remove some microorganisms harmful to human body.

what are the safety hazards of washing dishes with detergent?

Detergent is extracted from petroleum

First of all, in terms of composition, detergent is actually extracted from petroleum, which belongs to chemical products, and in the subsequent processing and production, other chemical materials such as essence and thickener are added, so its own components are not natural edible products, which are naturally harmful to human body.

It's not good to use too much detergent

We use it almost every day, especially for housewives, who often use it to clean things, and some even use it to clean apples, pears and other fruits. Therefore, many people will have some adverse reactions or allergic symptoms.

Detergent residue can't be washed clean

As far as our daily use is concerned, we can't completely clean the detergent on the dishes and bowls. Even if you wash them with clean water for 1 times, there is still a certain amount of residue on them, not to mention that many people like to put a lot of detergent. In this way, these residues are mixed with food and enter the stomach every day, especially if the pot is stained with detergent. With the increase of temperature, it will definitely cause changes, which may produce other toxins.

After washing the dishes, we can still detect an average residue of .3% after washing them with tap water for 12 times. Don't underestimate this .3%. We use detergent every day, and the average washing time is not 12 times at all. We eat this residue every day after eating and drinking soup, and it's no problem for two days a day, and it's not a big problem for a year or two, but after ten or twenty years, the problem will be big.

Detergent is harmful to the body

When surfactant enters the body, it will interfere with all metabolism of the human body, and the biochemical reaction caused by its metabolites in the body will cause great harm to the body, especially the influence on fertility and reproduction; Embryotoxicity, teratogenicity, mutagenicity, carcinogenicity, sensitization, hemolysis, etc. Washing powder, soap and detergent all contain surfactants, which must pass the national test of teratogenicity, carcinogenicity and pathogenicity as required, but at present, there is no requirement for chemical products in the country.

Danger of contact with pregnant women

Especially careless use by pregnant women is not conducive to the development of the fetus. Among them, the chemical components such as alcohol sulfuric acid and linear alkyl sulfonate can be absorbed by the human body through the skin and mucosa. If pregnant women are exposed to it for a long time, when the fertilized egg develops and divides into four cells (about 48 hours after fertilization), it will deform the egg cell membrane and lead to the death of the fertilized egg.

Since there are many hidden dangers in the improper use of detergent, we should pay more attention to the safe use of detergent in our life.

how to use detergent safely?

dishwashing liquid can be used in the following two ways:

1. Dilute the detergent with water to 2? 5 times, soaking time 2 minutes to 5 minutes, scrubbing with sponge or rag, and rinsing with flowing water.

2。 Pour the detergent directly on the sponge or rag, dip it in a small amount of water, then scrub the tableware (pay attention to wear rubber gloves), and then rinse it with flowing water.

It is suggested to adopt the second washing method, which has high washing concentration and good washing effect, and even heavy oil stains can be washed well.

the steps of washing fruits and vegetables are as follows: firstly, rinse off the dirt on the surfaces of fruits and vegetables with clear water, and then add detergent to soak them for 5? Ten minutes. Note that the concentration of detergent should be about .2%, or follow the instructions of detergent. The soaking time should not be too long, so as to avoid excessive penetration of detergent into fruits and vegetables, leading to the loss of vitamins contained and the decline of nutritional value. After soaking, rinse 2 with running water. 3 times, and then the fruits and vegetables are selected and cut.

Precautions for using detergent

1. Select qualified detergent produced by regular enterprises

The trademark pattern of detergent label (or label) produced by regular enterprises is clearly printed (the pattern overprint is accurate and unambiguous), and there is no deinking phenomenon. At the same time, the label (or bottle body) has the production license number, production date and shelf life or limited use date. In addition, information such as instructions for use, implementation standards, net content, factory name and address will also be marked one by one.

2. Try not to use or use detergent as little as possible

For example, if the pot containing porridge and rice is not greasy at all, there is no need to use detergent at all, just wash it in time after use; For another example, some dishes that are not very greasy can be washed directly with hot water. Similarly, some dishes that are too greasy can be washed with hot water before using detergent, thus reducing the use of detergent.

3. Minimize the residual amount of detergent

For example, it is best not to squeeze detergent directly on tableware. You can first add a few drops of detergent to half a bowl of water, then scrub the tableware with the diluted detergent, and finally remove the residual detergent from the tableware with flowing water. Be sure to wash it with running tap water for more than 3 times, instead of washing it repeatedly in a basin of clean water to avoid chemical residues.

Therefore, everyone should use detergent safely, not blindly, or it will affect their health.
