Hmmm... is it listed as a preservative?
If so, that's interesting. Because I'm allergic to the preservatives in most contact solutions (at least that's what my optometrist guesses, based upon the fact that my current solution has no preservatives and I tolerate it fine). Can't recall what is typically used, since obviously I don't
buy it, but for some reason I recall it starting with a "P".
I
vape PG with no problems.
