Specific migration testing – primary aromatic amines (PAA)

Primary aromatic amines (PAA) are a class of compounds that are generated when residual isocyanate groups in food contact materials react with the water in foods. In addition, articles in which aniline, benzidine or other PAAs have been used a precursor for pigments or as curing agents can be a source for restricted PAA.

Certain PAAs are known carcinogens, and these are listed in entry 43 to Appendix 8 of Annex XVII to Regulation (EC) No 1907/2006 of the European Parliament and Council. These PAAs are not allowed to migrate into food or food simulants.

Primary aromatic amine testing is especially relevant for products that contain, for example, the following:

  • Substances that contain aromatic isocyanate groups

  • Polyurethane-based materials

  • Azo dyes

  • Recycled plastic
