Guard Against The "Stumbling Block" Of Exporting Azo Dyes To EU Countries

The EU has issued two consecutive cases of excessive azo dyes which do not comply with EU REACH regulations.

First, France has a brand of black. Short sleeve Women's jackets give consumers warnings. Because the woman's coat contains azo dyes, the aromatic amine released exceeds the limit value of 30mg/kg. The importer / distributor has taken measures to withdraw the market and recall the product.

Two, Finland issued a consumer warning for a brand scarf. The orange scarf was made of 100% silk, and the azo aniline containing 450mg/kg was released by the azo dye. The Finland authorities have adopted measures to refrain from importing the product.

In the structure of dyes, azo dyes are all known as azo dyes. At present, there are six hundred or seven hundred kinds of azo dyes circulating in the market. There are many direct dyes, acid dyes, disperse dyes, reactive dyes and cationic dyes all are azo dyes. Therefore, not all azo dyes are banned, but only the 24 specified category can be released after reduction. Aromatic amines Azo dyes (especially aniline Series).

Use these disables azo dye When processed consumer products contact with human skin, aromatic amine compounds will become the inducement of cancer.

Inspection and quarantine experts pointed out that as one of the most widely used synthetic dyes for textile and leather clothing in printing and dyeing process, the possibility of direct use of banned azo dyes in production process is relatively small. However, other hidden risks in production, such as dyes with insufficient purity or improper use of auxiliaries, may result in the prohibition of excessive azo dyes.

The banned azo dyes directive covers a wide range of products, including garments, textiles, yarns, bedding, towels, handbags, wallets, leather shoes, wigs, hats, diapers, toys, and more than 10 other products. The inspection and quarantine department reminds enterprises to take precautions against three aspects of azo dye risk: first, strictly check and check the raw and auxiliary materials, formulate strict supplier evaluation and management system, and strengthen the quality and safety control of raw materials and auxiliary materials used by the outsourcing party.

Two, we should strengthen communication with the inspection and quarantine departments, keep abreast of the latest technical regulations, standards and dynamic changes in foreign countries, adjust the production process requirements, increase testing and monitoring efforts, and improve the detection efficiency.

Three, we should intensify the research and development of new environmental dyes, search for new azo dyes instead of products, and eliminate the use of azo dyes.
