* Only one of all the dyes tested in the UK study is a member of the azo chemical class. In the United States, 90% of food dyes are occupied by azo dyes Red 40, Yellow 5, and Yellow 6. However, FDA does not recognize the variability of behavioral reactions to dyes but protects sensitive children, but I believe that this variability is the reason why no action is taken. The US Food and Drug Administration states that the impact on the behavior of dyes is not due to being toxic to the child's developmental body but to "children with unique intolerance" 78. Please carry out a reliable neurobehavioral test using this unique intolerance.

Dyeing is the application of dyes or pigments to textile materials such as fibers, yarns and fabrics in order to obtain colors with the desired fastness properties. Dyeing is usually done in special solutions containing dyes and specific chemicals. Dye molecules are fixed to the fiber by absorption, diffusion or bonding, temperature and time are important control elements. The bond between the dye molecule and the fiber may be strong or weak depending on the dye used. Dyeing and printing are different uses, the printed color is applied to a local area having the desired pattern and is applied to the entire fabric during dyeing.

Historically, the main source of dye was natural, and the dye was extracted from animals or plants. However, since the mid-nineteenth century, humans have produced artificial dyes to obtain a wider range of colors and to make dyes more stable in cleaning and general use. Different kinds of dyes, from loose fibers to yarns and from fabrics to finished goods, are used at various stages of the manufacturing process of various kinds of fibers and fabrics. The oldest dyed flax fiber was found in the Georgian prehistoric cave and dates back to 34,000 BC. Further evidence of textile dyeing can be traced back to the neolithic Neolithic Neolithic period of Neolithic Atalhöyük in Southern Anatolia. In China, dyeing by plants, bark and insects dates back more than 5000 years ago.
