Zubora 6000 H EP is inhibited against the formation of nitrosamines, which means that even if there are any secondary amines and nitrites (e. g. through foreign carry-over), no stable nitrosamines can be formed. Therefore, in case of exceeding the limit value for nitrite according to TRGS 611, it is not necessary to make
a partial or complete change of the emulsion.
