AZO (azo compound)

Product introduction： Summary of Certification ContentA type of organic compound in which the two ends of an azo group are connected to an aromatic group. Azo dyes are the most diverse type of synthetic dyes, widely used for dyeing and printing various natural and synthetic fibers, as well as for coloring paints, plastics, rubber, etc. Azo dyes can release aromatic amines, some of which are harmful substances. The azo involved in electronic products mainly refers to the fabric and leather used in the product or packaging. In addition, the coloring of paint, plastic, and rubber is also useful.Article 43 and Appendix VIII of REACH Annex 17 list 22 azo dyes, aromatic amines, and limit their use. The limit value is 0.003% (mass ratio of each aromatic amine in the finished product or dyed part). The 2002/61/EC directive is consistent with REACH.In addition, some standards limit 24 aromatic amines.Please note that not all azo fuels are harmful. Currently, only 22 (or 24) are restricted, and the limit is that the content of each substance does not exceed 0.003%, not the sum of all substances.

Project introduction： AZO azo compounds are mainly present in dyes such as textiles and leather, and many azo compounds have a carcinogenic risk. Therefore, leather and textiles entering European and American countries must undergo AZO testing
