looking at the msds for reprogel (solution B), the only chemicals that are unusual are 2-pyrrolidinone (aka 2-pyrrolidone) and ethanediol (aka ethylene glycol).

keep in mind that the formulation of reprogel is proprietary and patented.

If it is patented, then you can find out exactly what is in it and how to make it. This is quite different from what is normally called "proprietary" which usually means "it's a secret and I won't tell you."

you're right, probably not proprietary, especially since the msds tells the percentage of each component in the stock buffer.
