Dishwashing liquid, as the most common washing product in daily life, can help us easily remove oil stains from dishes and chopsticks. It is particularly convenient to wash dishes. However, in recent years, Dishwashing liquid has been controversial.

There was an article on the Internet about "Dishwashing liquid is harmful! It can cause cancer if you can't clean it". Many people were very frightened after reading this article, but different people have different views on this point of view.

Young netizens often stand on the side of using Dishwashing liquid, thinking that if Dishwashing liquid is not used, the dishes and chopsticks in the home will emit oil, which is not hygienic at all.

However, for older people, they firmly stand on the side of not using Dishwashing liquid, because they believe that Dishwashing liquid is a chemical, and eating it in the stomach can really cause cancer. Even if it is washed several times, the residue of Dishwashing liquid can not be washed away. What is the truth? Let's take a look together today!

Action principle of Dishwashing liquid:

First of all, we should understand why Dishwashing liquid has such a strong ability to remove oil stains, mainly relying on the hydrophilic of Dishwashing liquid surfactantGroups and hydrophobic groups work together.

According to similar compatibility principles, hydrophobic groups can fuse with oil,The hydrophilic group can be hydrophilic with water, so when we use Dishwashing liquid to wash dishes, the hydrophobic group can wrap the oil stain, and then expose the hydrophilic group outside, so that the oil stain can be easily removed.

CCTV calls Dishwashing liquid formaldehyde, carcinogenic?

In 2014, the country carried out a spot check in 28 provinces. This time, the quality spot check was Dishwashing liquid, but the qualification rate was not particularly ideal at that time, only 93.6%. The main reason for disqualification was that detergent contained formaldehyde.

Formaldehyde doesn't need to be introduced too much. Everyone knows that formaldehyde has already been listed as a first-class carcinogen by the World Health Organization. If we are exposed to formaldehyde for a long time, it is easy to suffer from respiratory diseases and even cancer.

Then why should formaldehyde be put into detergent? Because formaldehyde has antiseptic effect, it can extend the shelf life of Dishwashing liquid, and formaldehyde is a very cheap preservative.

When the country realized this problem, it began to improve the detection standard of formaldehyde, so the regular Dishwashing liquid on the market was made in full accordance with the national mandatory standards, which contained less than0.1mg/g, if it exceeds this red line, it will cause certain harm to the body. So when you buy Dishwashing liquid, don't buy some cheap Dishwashing liquid for the sake of cheap.

Can residual substances also cause cancer?

If Dishwashing liquid is not used correctly or rinsed properly, it will leave some chemical components. Many people doubt that these residues will cause cancer after a long time.

For this reason, a TV station has also made a survey, using 9 kinds of Dishwashing liquid on the market to clean the tableware, and washing it with tap water for 12 times, and still can detect about 0.03% residue on the tableware.

Although this residue is not large, we use Dishwashing liquid every day, and when we wash dishes and chopsticks, it is impossible to wash them more than 12 times. Theoretically, we do eat some trace residues in the body.

So over time, will it actually trigger cancer? On this question, we need to understand the specific chemical composition of Dishwashing liquid. Our daily Dishwashing liquid mainly containsSurfactants (such as sodium alkyl benzene sulfonate, fatty alcohol ether sodium sulfate, etc.), essence, pigments, etc.

The purpose of essence and pigment is easy to understand. It is mainly to make the smell of cleaning essence fresh and the color beautiful. Surfactants are mainly compatible with oil and water. The harm to human body caused by the composition of this surfactant is negligible, except that you pick up Dishwashing liquid and drink it ton by ton.

Doctor's confession: Two types of detergents should be blackened out early

1. Dishwashing liquid with strong fragrance

When using Dishwashing liquid, you must pay attention to the fragrance. It is not recommended to buy Dishwashing liquid with a strong flavor, because many businesses will make the fragrance of Dishwashing liquid more strong in order to increase the sales volume of Dishwashing liquid. However, some harmful substances are added to this detergent, which may cause dizziness, rash, etc. if used frequently.

2. Bulk Dishwashing liquid

In order to get cheap, many vendors will buy Dishwashing liquid in bulk and put it into their own containers for use. In fact, the safety of this kind of Dishwashing liquid in bulk is not guaranteed by formal manufacturers, and there are many harmful substances. If you use this Dishwashing liquid frequently, it will lead to the intake of harmful substances, increase the risk of disease in the body and increase the risk of cancer, so we try to avoid it.

Can dishwashing sponges also cause cancer?

Many people like to use a sponge when washing dishes, but now some online people say that sponge wipes can also cause cancer because they contain some harmful ingredients,

Actually, sponge wipes are made from melamine and formaldehydeThe good decontamination effect of "melamine resin foam" comes from the unique material and structural polymer, which will inevitably release some monomer molecules, so it is not surprising that the sponge can release formaldehyde.

However, the formaldehyde released by sponge wipes will dissolve in water and run away, even if dispersed into the air, a small concentration can be directly ignored.

However, sponge wipes can breed bacteria over time, so it is important to replace them regularly. After use, it is also important to dry the water inside and air it in a timely manner.
