Hello removed link

I have optiphen and neodefend in my cabinet as my removed link I've had then for a long time (like over two years). I would like to know do preservatives have an expiration date?  I looked on the containers and it says removed link Also I tried to Google it but still no removed link

Thank You

Neodefend: The shelf-life of Neodefend is up to 3 years (according to

Optiphen: I know that Optiphen Plus has a recommended shelf life of 24 months (  I'm not sure about the shelf life of regular Optiphen.

Yes, according to what I've seen, preservatives do expire. But usually it takes years for them to go bad.
