As the product does not contain any secondary amines, there is no risk of formation of nitrosamines according to the current state of knowledge.
As Zubora 57 H Plus is inhibited against the formation of nitrosamines no stable nitrosamines can be formed, even if there are any secondary amines and nitrites (e. g. due to external carry-over).
