The supermarket sold at a reduced price and cleared the warehouse, and the aunts in the surrounding communities flocked to the mall early in the morning, looking at the dish soap that only cost a few yuan, Aunt Liu hurriedly grabbed several bottles.
Just when he was proud of the wool, his friend saw it and said: "What are you doing with this thing, the news has reported that dish soap can cause cancer, and we don't dare to use it." I now blanch it with boiling water, which is cleaner than washing with dish soap."
When she heard that it caused cancer, Aunt Liu was stunned, so she couldn't finish using dish soap for so many years?
1. CCTV named dish soap as containing formaldehyde and can cause cancer?
Everyone should be familiar with the statement that "so-and-so" causes cancer, and the most shocking of them is that "dish soap contains formaldehyde and can cause cancer", is it the "carcinogenic theory" of the marketing account?
As early as 2014, the relevant departments carried out a special investigation on detergent products, and formaldehyde and other first-class carcinogens were detected in unqualified batches.
After investigation, it was found that some unscrupulous merchants would add excessive formaldehyde to their products in order to extend the shelf life of dish soap.
However, formaldehyde and carcinogenic cannot be simply equated, even if formaldehyde is present, it must reach a certain dose to be carcinogenic, so there is no need to worry too much.
According to the requirements of Continental's safety standards for detergent products:
Class A dish soap, that is, a detergent that can clean food, contains no more than 0.05% of formaldehyde;
Class B is the common dish soap for cleaning dishes, and the formaldehyde content cannot exceed 0.1%.
In fact, as long as the product meets the standard, it generally does not pose a threat to human health!
2. How much residue is left in dish soap when washing dishes, and is it harmful to the human body?
Of course, many people may say that there will be residual problems with dish soap used for many years, and it will not really be harmful to the human body?
In fact, in addition to water, the main ingredient of dish soap is "surfactant", even if this ingredient will remain in the dishes and chopsticks, the human body needs to directly drink more than 1 bottle of dish soap to achieve a toxic reaction.
As for washing several times before cleaning, whether there will be a residual problem, some experts have done special experiments for this, and found that after the first rinsing, the basic residue is perfectly up to standard, and the residual amount after the second flushing is already lower than the national standard, and the residual amount after three rinsing has been basically maintained at 0.01 mg/cm², which is 10 times lower than the national standard.
Therefore, experts recommend that as long as you clean it twice, you don't have to worry about the residue problem, and if you don't worry, then clean it a third time.
Moreover, washing dishes and chopsticks with dish soap can also effectively reduce the density of E. coli flora, plus rinsing with hot water, it can also be immune to the threat of most microorganisms, so it is still necessary to use dish soap.
If you have to find a little harm, you can count it as a little bit of injury. Because the detergent's decontamination ability can also destroy the protective lipids on the surface of human skin, our hands will be dry and peeling after long-term contact.
3. These 3 kinds of dish soap should really be used sparingly
Although the detergent on the general shelf is in line with the national safety production standards, there are also some products that will have some negative effects on the human body after use, especially the following 3 kinds of detergents, which need to be vigilant when purchasing.
1. Aromatic dish soap
According to a study by the University of Melbourne in Australia, 33% of people experience headaches, dizziness, nausea and other discomforts due to exposure to aromatic products. Researchers believe that this may be related to the chemical contaminants contained in aromatic products. Therefore, the same is true for dish soap with a strong fragrance, and it is best to use it sparingly.
2. Bulk dish soap
Although this kind of dish soap is rarely seen on the market, it still exists in some backward areas, and because of its low price, it is often very popular, but because the production process cannot guarantee safety standards, the total number of colonies and pH value may exceed the standard.
3. Layered and turbid dish soap
Generally, normal dish soap is evenly distributed and has high transparency, if there is delamination and turbidity, it may be caused by problems in the product production process or expired products, and it is best not to use it.
Overall, if you want to buy a safe dish soap, it's best to look for big brands, pay attention to the ingredients for harmful ingredients, and don't forget to use the right amount to reduce damage to your skin.
Fourth, these 4 bad Xi of washing dishes hurt more, don't take it seriously!
Many bad Xi habits in life may have been harmful when we are not aware of it, even tableware and chopsticks may lead to "disease from the mouth", do you have these bad Xi habits when cleaning dishes and chopsticks?
1. The dishcloth is not replaced for a long time
Many people run out of dishcloths, often put a place in hand, and continue to use it next time, but it is such a Xi, in fact, in the cultivation of bacteria, the Chinese Center for Disease Control and Prevention has done a sampling survey on this, and found that the number of bacteria per square centimeter of dishcloths that have not been replaced in time is as high as more than 6 billion, including pathogenic bacteria.
2. Soak the dishes and chopsticks for a long time
Many families are too lazy to wash the dishes and put the used dishes and chopsticks in the sink to soak, but as everyone knows, this behavior is actually breeding bacteria, and the residual food residues and grease provide sufficient nutrients for bacteria to multiply. Studies have shown that soaking dishes and chopsticks in water for 10 hours will increase the amount of bacteria by 70 times!
3. Put away the dishes and chopsticks before they are dried
If the dishes and chopsticks are not dried, it is easy to breed bacteria in a humid and closed environment, especially for families who like to use wooden chopsticks, if they are not dried thoroughly, they will not only become moldy but also easy to breed carcinogenic aflatoxin.
4. The dishes are washed and stacked without drying control
If the dishes are not dried uncontrollably, they will also create a natural living environment for bacteria because of the stacking structure, so it is best to dry the washed dishes in time before storing.
In general, daily hygiene Xi habits can not be ignored, usually use dish soap to clean dishes and chopsticks should also pay attention to rinse several times, after all, health is your own, do not easily let bacteria have a chance.
