According to CCTV news reports, the State Administration for Market Regulation recently carried out random inspections. During the inspection process, an item labeled as produced by Shenzhen Anruoyi E-Commerce Co., Ltd. The fashionable Hanfu was found to have a carcinogenic aromatic amine dye called "benzidine" that exceeded the standard, and the exceedance was very serious. Testing engineers said that the carcinogenic aromatic amine dye in this product was measured to be as high as 540 mg per kilogram, 27 times exceeding the standard. This means that the carcinogenic dye has a higher concentration and poses a higher safety risk to human health.

In addition to the above-mentioned Hanfu, a denim vest produced by Dongguan Manbang E-Commerce Co., Ltd. was also found to contain carcinogenic aromatic amine dyes exceeding the standard value. , reaching 30 mg per kilogram.

According to reports, during long-term contact with the human body, the harmful ingredients of dyes synthesized from carcinogenic aromatic amines are absorbed by the skin and decomposed under special conditions. More than 20 carcinogenic aromatic amines form carcinogenic aromatic amine compounds, which change the DNA structure of the human body through activation, which may cause lesions and induce malignant tumor substances, leading to malignant diseases such as bladder cancer, ureteral cancer, and renal pelvis cancer.
The Beijing News Shell Finance reporter found that my country’s mandatory standard GB 18401-2010 "National Basic Safety Technical Specifications for Textile Products" clearly stipulates that 24 decomposable and carcinogenic aromatic amine dyes, including benzidine.
Excessive levels of carcinogens in clothing are related to fabric printing and dyeing
Carcinogenic aromatic amine dyes are such serious hazards, and relevant standards clearly stipulate that they are prohibited. Why do problems of exceeding standards still occur?
Cheng Weixiong, an independent analyst in the footwear and apparel industry, said that clothes contain carcinogenic ingredients that seriously exceed standards, mainly caused by fabric printing and dyeing. As upstream companies in the clothing industry, we should strengthen our moral bottom line requirements and eliminate chemical raw materials that come into direct contact with the skin and have adverse effects on the body.
The Beijing News Shell Finance reporter learned from the testing engineer of the China Chamber of Commerce Knitted Cotton Commodity Quality Supervision, Inspection and Testing Center (Tianjin) that benzidine is an intermediate for some azo dyes. Raw materials used need to be confirmed. Clothing testing found that carcinogenic aromatic amine dyes exceeded the standard, indicating that some manufacturers have certain problems in fabric selection and processing technology during the production process.
An industry insider who did not want to be named revealed to reporters that some printing and dyeing companies may not have enough knowledge about compound dyes and splicing dyes, and they are not sure whether benzidine will be decomposed under certain special circumstances. Or some small dye factories do not have strict control, resulting in the dye itself containing unreacted benzidine.
In addition, insiders in the industry said that at present, it is relatively rare for this kind of clothing on the market to have carcinogens that exceed the standard. Only in a few cases will the test fail. The problem first lies in the packaging of clothing, especially close-fitting clothing. Clothes that have been stored in sealed packaging materials for a long time will contain substances exceeding the standard within a short period of time after being unpacked. This is related to the packaging materials. It is relatively rare for dyes to contain carcinogens exceeding the standard.
The Beijing News Shell Finance reporter discovered through the Tianyancha App that Shenzhen Anruoyi E-Commerce Co., Ltd. was established in 2014 and was listed as having abnormal business operations because its registered residence or business place could not be contacted. Directory, the company has been canceled on April 26, 2022. It is worth noting that the company’s quarterly inspection in August 2021 was detected by the Shenzhen Institute of Metrology and Quality Inspection as decomposable carcinogenic aromatic amine dyes.
What should you pay attention to when purchasing clothing?
The reporter learned that carcinogenic aromatic amine dyes contained in clothing cannot be eliminated through daily cleaning and ironing. It is also difficult for consumers to identify them when purchasing clothing, but they can be carefully identified. Check the implementation standards and safety categories and other information on the clothing tag to avoid them.
According to the "National Basic Safety Technical Specifications for Textile Products", the basic safety technical requirements for textile products are divided into Category A, Category B and Category C according to the degree of index requirements. Infant textile products should meet the requirements of Category A. , products that directly contact the skin should at least meet the requirements of Category B, and products that do not directly contact the skin should at least meet the requirements of Category C. Category A requires that the formaldehyde content be less than 20mg/kg, Category B requires that the formaldehyde content be less than 75mg/kg, and Category C requires wantIt is required to be lower than 300mg/kg, but the above three types of textile products are prohibited from decomposing carcinogenic aromatic amine dyes.
The China Federation of Commerce’s Knitted Cotton Commodity Quality Supervision, Inspection and Testing Center (Tianjin) recommends that when purchasing clothing, consumers should try to purchase through formal channels; purchase clothing with safety labels, or pay attention to product hangtags and labels (see if GB 18401 is marked on adult clothing, and GB 31701 is marked on children's clothing); choose products without pungent odors; it is best to choose light colors for underwear; it is best to wash them before wearing them, if the color fades very much Serious, it is recommended not to use it.
