Due to the use of primary amines there is no risk of formation of nitrosamines according to
the current state of knowledge.

Furthermore, Zubora 67 M Ultra is inhibited against the formation of nitrosamines, i.e. that
even if there are any secondary amines and nitrites (e. g. through foreign carry-over) no stable
N-nitrosamines can be formed. When exceeding the limit value for nitrite according to TRGS 611
a partial or complete change of the emulsion is not necessary.
