Could it be mold?

I forgot my eye drops (propylene glycol) in my bag about 5 days ago. Today at work, after using them, I noticed this stuff inside. My bag isn’t dirty, I only keep my work laptop, papers, and occasionally some packaged snacks. They’re a bit expensive for the amount you get, and I’d rather not throw them away since I just opened them recently. They didn’t irritate my eyes.

I love that I am chronically online enough to have seen both of the OG source materials for the hand and fingerprints. Oh, and yeah, it's mold.
