Determination of Azo Dyestuff

The use of chemicals is inevitable in the production processes to give the products the desired properties. The existence of chemicals used in production and their effects on humans have begun to be questioned. It is imperative to determine whether it is harmful to human health or not. Azo dyes consist of organic and -N=N- azo groups. Azo dyes are carcinogenic and are classified as banned chemicals.

Azo dyestuff is used in Furniture Textile Products, Leather Textile Products, Home Textile Products, Yarn, Fiber Production, Stationery Materials, Toy and Accessory Materials, All Textile Materials.

Azo dyes; It is tested in products due to its allergenic, carcinogenic and mutagenic effects and toxic effects. Banned azo dyestuffs are listed as follows.

• 4-Aminodiphenyl
• Benzidine
• 4-Chloro-o-toluidine 
• 2-Naphthylamine
