Aromatic Amines - false positve results are always annoying!


Many Pigments of certain shades show the occurrunce of 2 Amines listed in the EU ResAP(2008)1 and the German Tätowiermittelverordnung. Our detailed investigations into this matter show they are not a result of AZO-bond cleavage and are therefore false positive results. They are also not present in the pigments before reduction. Should you have such results from elsewhere please inquire and we will assist you in clarifying the false results.
