Due to the use of primary amines there is no risk of formation of nitrosamines according to
the current state of knowledge.
Furthermore, Zubora 65 S Extra 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. Therefore, when exceeding the limit value for nitrite according to TRGS 611 a partial or complete change of the emulsion is not necessary.
