While the biohazards of industrial solvents was not my main educational/employment focus (Physics and Philosophy were my twin crosses to bear LOL..., I do know that toluene is one of the more benign of the largly benzene ring based chemicals.

Benzene, as was already mentioned, and especially CCL4 (Carbon Tet.) would be several orders of magnitude more dangerous to work with without a proper vent exhaust.

And it's way out of my league to speculate on the more sophisticated solvents developed in the last 30-40 years.

Before using any of these products it would be best to contact a local Health dept. or university chemistry dept. first.

I want all our members to live as long as possible.
