Dear Sir In the August issue of Contact Dermatitis was published the article ‘Allergic contact reactions from poly(oxy-1,2-ethanediyl) a ,aø-[(1-methyl-ethyliedne)di-4,1-phenylene]bis[w[(2-methyl-1-oxo-2propenyl)oxy] (BIS-EMA)’, which I co-authored with Professor L. Kanerva (1). The message that I tried to convey is that looking at chemicals by their idealized structure leaves an important, in some cases even the essential, element out, the rôle of impurities; sometimes, more important even, the fact that certain chemicals have a molecular weight distribution rather than consisting 100% of only one, well-defined chemical.
