According to current knowledge, the use of primary amines poses no risk
of nitrosamine formation.
In addition, Zubora 67 M Ultra is inhibited against nitrosamine formation, i.e. no stable N-nitrosamines can be formed in the presence of secondary amines and nitrite, e.g. from external entrainment
. If the limit value for nitrite according to TRGS 611 is exceeded, a partial
or complete replacement of the working emulsion is therefore not necessary.
