I was not able to find the solvent for those Sharpies.
Only these:

Product Name:
Sharpie Professional Marker,
Sharpie Industrial Marker,
Sharpie CD Marker.
Solvent Mixture:
Butanol (71-36-3),
Propanol (71-23-8),
Diacetone Alcohol (123-42-2),
Ethanol (64-17-5)
Neither of those mixes is especially aggressive on plastic. I was hoping to see some Xylene in it. When I was trying to get ink to stick to plastic D&D dice, Xylene was the magic ingredient.
Toxic, though.
From the ads, it sounds like "Extreme" Sharpies mainly add some UV resistance against fading.
