Question about primer

Hello dear forum,
I want to paint Tiefgrund LF Acryl-Hydrosol (solvent-free, low-odor primer for interior and exterior) from Meffert AG on the walls of a new apartment. Now I have become suspicious because it says "contains: Methyl-Benzyl-Isothiazolinone" keep out of reach of children, do not dispose of into the sewage system to protect the environment...
On the other hand, it says primer for exterior and interior. Is it possible that the walls will continuously off-gas and that this could harm health?

Best regards Frank

Hello Fran,
I just read - also for rooms in the food sector -
one should really read the data sheet carefully, but I can’t find it quickly.
