Many studies have shown that azo dyes are direct flow of dyes, mostly using sodium salts of sulfonic acids or organic carbonic acid - being used in many clothing manufacturers around the world.

In the chemical aspect, colors are divided into groups such as Azo color, Anthrachinon color, Metal color complex and other groups. For the azo group, when these azo compounds enter the body, they can decompose in the body's metabolic system and produce aromatic amine .

This is not a substance but a group of organic compounds with aromatic structure and substituents amine. Because it is amine, their pH is greater than 7, when exposed to high concentrations it is not good for the skin.

Long-term exposure, amine can penetrate easily through the skin, cause allergy, skin irritation , leading to skin diseases such as atopic dermatitis . More dangerous, Azo decomposition process can occur in the road intestine, in the liver or cause cancer.
