Azo dyestuffs with some cancer-causing effects are identified as a result of tests performed in some apparel, apparel, textile and leather products imported especially from Far East countries. The Ministry of Health constantly warns about this issue and tries to prevent the entry of textile products that are dangerous for human health.

According to the current regulations, it is free to import azo dyestuff products below a certain ratio in our country. However, unfortunately, the developments have increased to worrying dimensions. Occasionally, azo dyestuffs are found above the specified limits in textile products that directly contact the human body. This is a great risk to the health of society.

There are 24 azo dyestuffs that are harmful to the European Union and should not be produced or used. However, the use of azo dyes up to 30 ppm is permitted in our country and other countries.

The purpose of the use of azo dyes in the textile sector is to ensure that the dyes used are fully settled on the product. However, their carcinogenic properties are also known. In the inspections, products containing azo dyestuffs are determined much higher than the limit value of 30 ppm (3000 ppm) in textile products. Wearing a fabric of this level is a big risk, not even touching it.

The arylamine contained in these dyes, defined as azo dyes, has a carcinogenic effect.

In this respect, a lot of work is required from domestic or foreign accreditation organizations to laboratories accredited under TS EN ISO / IEC 17025 standard. These laboratories carry out azo dyestuff tests and other carcinogenic substances tests in textile products within the scope of chemical and ecological tests. These tests and analyzes are based on standards published by domestic and foreign organizations.
