Determination of Azo Dyes: Detection of Harmful Chemicals in Textile Products

Why Determination of Azo Dyes in Textile Products? Hazards of Azo Dyestuffs...

What are Azo Dyes?

Azo dyes are synthetic dyes that contain nitrogen bonds in their chemical structure and usually provide bright colors. Azo dyes offer a wide range of colors and are widely used in the textile industry due to their low cost. However, some azo dyes may contain compounds that can be particularly carcinogenic and lead to allergic reactions. These harmful compounds can be released by nitrogen bonds in the chemical structure of azo dyes.

Some types of azo dyes can release aromatic amine compounds during washing, perspiration or friction. These aminyang compounds can be carcinogenic when in contact with skin. Therefore, in some countries, especially in the European Union, the use of azo dyes is strictly controlled.

Why is Azo Dyestuff Determination Important?

The presence of azo dyes in textile products can carry serious health risks for both the manufacturer and the consumer. The detection of azo dyes in textile products is very important for the following reasons:

Health Risks: Some azo dyes can cause health problems such as skin irritation, allergic reactions or cancer when in contact with the skin. The aromatic amine compounds that azo dyes can release through washing or friction can have potentially carcinogenic effects.
Harmful Effects on the Environment: Azo dyes can cause environmental pollution when released into the environment as chemical wastes. These chemicals can contaminate water resources and have negative effects on the ecosystem.
Legal Requirements: Many countries, especially in the European Union, have laws restricting the use of azo dyes in textiles. The identification of azo dyes is important to comply with these laws. For example, in the European Union, certifications such as REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) and OEKO-TEX® Standard 100 are regulations that control the use of azo dyes.
Consumer Safety: Azo dyes can pose a health threat in products that come into direct contact with the skin (especially underwear, baby clothes, etc.). Therefore, the absence of azo dyes in these products provides a major safety measure.

Azo dyes (aryl amines) are synthetic organic compounds in the azo group in molecular structure. Approximately 2/3 of the synthetic dyes used worldwide are azo dyes.
