The aromatics amines are organic substances constituted by a group -NH, NH2 or nitrogen attached with aromatics hydrocarbons whose structure normally contains one or various benzene ring.

The aromatics amines in consumer goods come from the use of azoic dyes, which are useful for the degradation of the same during the use of the product, for example, in the case of textile in contact with skin, or as unwanted sub-products during the product manufacture, like for example could happen in the case of finger paints.

Azoic dyes are the most used in the industry to colour every type of raw materials like textiles, plastics, paints, cosmetics, food, etc. they are organic matter which contain in their structures as a minimum an azo group, –N=N–, usually found between aromatic rings.

The reduction of some of those dyes generates the formation of aromatic amines. The aromatic amines are generally considered to be dangerous substances for the environment and toxic for the health, considering some of those carcinogenic. That is why, the presence of those substances in consumer goods is restricted by various laws and regulations like the Regulation (CE) n° 1907/2006 REACH in its annex XVII or the Toys Directive with the application of the Norm UNE-EN 71-7 on the security for finger paint. Mainly, they limit the presence of the following group of 22 aromatic amines (table 1), which will be the research topic of this investigation.

Large part of raw materials that compose child products can contain toxic or unwanted substances in their compositions. Several times, there is a lack of complete information concerning the components or substances which are used in the manufacture of raw materials, principally in the case of European market outside processes. For this reason, it is very difficult for the manufacturer to evaluate the risk he is exposing the consumer to because of this product and topractically respect the ongoing regulation in a simple and efficient way.
