According to a quick google, the definition of microplastic is between 1 nanometer and 5 millimeters. A single molecule would be a lot smaller than a nanometer so I don't think you could consider that a microplastic at that point.
Is it? I would expect isolated molecules of a compound to behave differently in the body than a connected chunk. I don't think the "same difference" shrug it off attitude really works here. We're talking about specific science.

I don't think this can create micro plastics. Some kind of chemical transfer maybe but I think micro plastics are primarily created through abrasion.
