Thank you @Frabaneda. I agree with you. And I guess EFPIA considered biological products as low risk with considering synthetic compounds you mentioned. Of course risk assessment is important.
And thank you for sharing the risk of packaging. EFPIA Flow has the packaging part, which targets Nitrocellulose.
@DAB also introduce interesting webinar.
I expect the nitrosamine contamination risk from Pkg Materials are not high in many cases when considering manufacturing and storage conditions… Does anyone have comments?
