Not so. The short of the story is this. Acute benzene intake (in
rodents) through inhalation or orally has been known to cause
cancers. But the long term low dosage exposure wasn't as
effective.

So you tell me that this commercial made absolutely no sense
whatsoever?

We used to work with such alcohol (benzene was used there to suck out
all water from ethanol to make permanent cytological samples) before I
abandoned experimental biology.

Same stuff.

Nobody would touch that stuff, even
though Soviet scientists and also non-scientific staff of academic
institutes would drink industrial grade alcohol without thinking
twice. Ethanol marked "for lab usage" used to be a sort of currency,
like for example if you needed to fix plumbing in the lab, or ask
professional divers to catch some sea animals on a stormy day. Your
chemistry professor didn't know what she's doing.

It looks like. I assume that she used sort of standard reasoning,
which pretty much regarded anything carcinogenic as harmless. I know I
did. ;-)
