ZUBORA UNIVERSAL FF contains inhibitors that block the formation of nitrosamines, i.e. if secondary amines and nitrites appear (e.g. as a result of precipitation of foreign compounds) stable, carcinogenic N-nitrosamines will not be able to form. Exceeding the limit values of nitrite according to TRGS 611 does not require partial or complete replacement of the emulsion.
