After testing hundreds of pieces, many families still use these high-risk products

"Dad's Laboratory" has been providing free testing activities for everyone for more than half a year. After more than 20 activities, it has found many unqualified products.

Parents often leave messages in the background, wanting us to talk about the test results of each activity and how to avoid pitfalls.

Today, "Dad's Laboratory" has summarized the test results of the samples sent by everyone, and summarized the common characteristics of some problematic products to serve as a reference for everyone's future choices.

01 Mercury in cosmetics: Be wary of products that work quickly, especially creams. "Dad Lab" has always provided a service to help fans send their products to third-party laboratories for testing at their own expense.

During the testing, we found that many beauty creams that claimed to contain "Chinese herbal ingredients", "xxx hospital products" and "cannot be bought outside" had excessive mercury. So we launched several free cosmetic mercury testing activities since March this year.

There were many parents who signed up, and we selected 430 of them and sent samples for testing. Among these samples, 75 products exceeded the mercury limit, with a failure rate of 17.4%.

According to parents, most of these products with excessive mercury content take effect very quickly, usually able to whiten and lighten spots quickly in a short period of time, but they are very prone to allergies and acne breakouts when used, and often rebound after discontinuation of use.

Our tests have found that mercury levels in these products are mainly cream cosmetics, especially those that contain night cream and day cream in a box, accounting for more than 90%. These products may not exceed the limit, but if they do, the levels are thousands or even tens of thousands of times higher.

Once heavy metal mercury enters the body, it will not only cause damage to the human kidneys, but chronic exposure can also cause varying degrees of damage to the nervous system, resulting in symptoms such as memory loss and daytime dizziness.

Therefore, parents should be careful when they come across products that can quickly “whiten and remove freckles”, especially cream products. Remember to check the website of the State Food and Drug Administration (click to jump) before purchasing.

To purchase domestic cosmetics with whitening and freckle removal effects, you can search in the category of domestic special-purpose cosmetics.

02 Children's shoes: Be wary of decorations on shoes and choose less leather materials. In March and April this year, we launched two free testing activities for children's shoes, with more than 1,000 parents participating. We screened some samples and conducted heavy metal testing and hardness testing.

The results showed that the 90 pairs of children's shoes we tested had no hardness problems, but among the 155 samples that underwent heavy metal testing, 6 pairs of children's shoes had high initial screening results for heavy metals, exceeding the national standard.

Among these children's shoes, we found that the arsenic content of the decorative beads on a girl's shoe reached 1641 mg/kg, more than 16 times the standard! The heavy metal content of some small leather shoes, leather sandals, and some unknown brand sports shoes was also detected to be excessive.

The decorative beads contained excessive arsenic, the black leather uppers contained excessive lead, and the pink leather buckles contained excessive lead

Heavy metals are easily absorbed by children's skin, accumulate in the liver and kidneys, and are difficult to degrade. When they accumulate to a certain level, they can cause chronic poisoning. In severe cases, they can damage children's central nervous system and have a great impact on their intellectual development.

Children are at the age when they love to touch and bite things. Some children like to touch the buckles of shoes, and some even bite the shoes. Therefore, when choosing shoes for children, you must be careful about the buckles and uppers, which are parts that children often touch.

We recommend that parents try not to choose shoes with decorations (in addition to the risk of heavy metals, there is also the risk of accidental ingestion), especially rhinestones, plastic, metal and other accessories, and choose less leather shoes or unknown brand shoes with leather buckles.

03 Sun-protective clothing: mainly look at the tag and implementation standards. Since May this year, we have launched two free testing activities for sun-protective clothing.

Our tests found that many sun-protective clothing do not meet the sun-protection requirements. Even the sun-protective clothing priced at 1,288 yuan does not meet the requirements. The sun-protection effect is not as good as the sun-protective clothing priced at 9.9 yuan (and the sun-protective clothing priced at 9.9 yuan does not meet the requirements), and is even not as good as ordinary clothes.

Moreover, the sun protection effect of sun protection clothing will also weaken after aging. There are many kinds of sun protection clothing, and it is not possible to simply judge by the standard of "you get what you pay for". The key is to see whether the sun protection clothing implements the standard GB/T 18830-2009 and whether it has a UPF sun protection label. Generally, UPF 40+ or ​​UPF 50+ is sufficient for daily use.

To determine whether the sun-protective clothing is outdated and cannot be worn, you can check whether the clothing is translucent, loose, or too tight. If it meets these three conditions, you can replace it.

If you want to choose sun-protective clothing for children, try to choose one that is soft, breathable and moisture-permeable, and has no sharp decorations.

04 Crawling mat: Try to choose PE material and ventilate it before use. This year we reported that Huang’s baby developed a rash when using a crawling mat with excessive formamide.

For the health of more children, we launched a free crawling mat testing activity. In this activity, we tested a total of 123 samples and found 37 unqualified products, with an unqualified rate of 30%.

From the questionnaires filled out by parents, we can see that many crawling mats with excessive formamide have a strong odor, and children experience allergies and rashes when using them.

According to EU Regulation EC No.1272/2008, formamide is classified as a Class 1B reproductive toxicant. It can be absorbed into the body through the respiratory tract, digestive tract and skin mucosa, causing irreversible harm to children.

Through this test, it was found that the proportion of unqualified formamide in old crawling mats was lower than that in new crawling mats, indicating that ventilation and drying are effective. Therefore, you can ventilate the crawling mat before using it.

At the same time, when purchasing, you can try to choose a crawling mat made of PE material. Pay attention to the crawling mat that says it is made of foam material. Try not to choose a spliced ​​type. If the surface of the crawling mat is severely damaged, it should be replaced in time.

The above products are what we found after testing and you can identify them through some methods. However, for children's facial creams, stainless steel products, rice noodles, fake cosmetics, silver jewelry and other products that we have found problems with, it is difficult for parents to identify them by themselves. If you want to identify them, you need the help of professional laboratories, or choose to buy big brand products through regular channels when purchasing.
