The Risk Level Of Six Valent Chromium In Leather Clothing Is Low Risk.

Recently, the Shanghai quality and Technology Supervision Bureau organized the risk monitoring of leather garment products quality and safety. Six batches of clothing were detected in 11 batches of clothing, of which 1 batches exceeded the standard.

The national mandatory standard GB20400-2006, "the limits of harmful substances in leather and fur", has clear requirements for the free formaldehyde content of leather and fur, and the content of decomposable aromatic amine dyes. The formaldehyde content in leather is less than 300mg/kg, which can decompose harmful aromatic amine dyes to less than 30mg/kg. However, the standard applies to leather and fur raw material products, not including the products they produce. Industry recommended standard QB/T 1615-2006 "leather clothing" harmful substances limit is also not provided. The recommended standard of industry QB/T 2880-2007 "children's leather shoes" stipulates that the six valence chromium content index of children's leather shoes is less than 10mg/kg, but there is no limit on the six valent chromium content in the leather clothing product standard.

In order to assess Leather clothing Product quality and safety status, Shanghai According to GB/T 19941-2005 "determination of formaldehyde content in leather and fur chemistry test", GB/T19942 "leather and fur chemical test banned azo dye determination" and GB/T 22807-2008 "leather and fur chemical test six valent chromium content determination", the quality supervision bureau carries on the testing to the content of free formaldehyde, decomposable harmful aromatic amine dyes and six valent chromium in leather clothing products, and carries out risk assessment according to the test results.

This time Risk monitoring A total of 50 batches of samples were collected. After testing, 47 batches of free formaldehyde were detected, but none of them exceeded 300mg/kg. 6 batches of samples were found to be able to decompose harmful aromatic amine dyes, but they did not exceed 30mg/kg. 11 batches of six valent chromium were detected, of which 1 batches of products were detected with six valent chromium content exceeding 10mg/kg. Leather clothing is a kind of non direct contact with skin. Taking into account the seriousness of risk and the possibility of risk, the risk level of formaldehyde, decomposable aromatic amine dyes and six valent chromium content in leather clothing is low risk by experts.

According to the results of risk monitoring, Shanghai Quality Supervision Bureau has informed relevant production enterprises, urged enterprises to strictly implement national standards, strengthened quality control, reduced or eliminated risks of quality and safety, and reported relevant departments on quality and safety risk information of leather garment products, and suggested perfecting relevant national standards. At the same time, Shanghai quality and Technology Supervision Bureau reminds consumers that when choosing and using leather garments, they should pay attention to buying leather clothing products produced by reputable enterprises in regular department stores and leather clothing stores. Because the product value is generally high, consumers should keep good shopping vouchers.

Quality supervision experts also remind consumers when choosing leather clothing, do not choose products with obvious pungent smell. The smell of leather is produced when the tanning quality is not good. It is not easy to distribute and is not easy to remove. When purchasing and wearing, you should carefully inspect the certificate, logo / label. The information of the label of leather clothing should include the name, address, telephone number, product name, trade mark, product number, specification, standard, place of origin, fabric material and material of the production / distribution unit, and the necessary product instructions. Consumers can purchase and use products correctly according to their identities.
