Canola oil is rapeseed oil, but rapeseed oil isn't necessary canola oil. They developed a cultivar of rape, I think it was in the 1970s, that has low ecruic acid levels, and once they got the US to approve the new name (canola is CANadian OiL), it only took about 2-3 years before farmers were growing large quantities. I can't see women buying rape oil. Even if they know better, it sounds like an antisocial alternative to KY jelly. 

If I recall correctly, regular rape oil is a drying oil, mostly used industrially, perhaps in some specialty paints. It's toxic, but I don't know *how* toxic. (A lot of the foods we eat are toxic. Salt is a necessity, but a cup of salt would be lethal to half of all adults who ingest it.)  

 thanks from me, too 

Not much time on my hands these days, but when I see something that is wrong, I have a hard time leaving it alone. Not a desirable character trait, I'll have you know. They say dentists and computer programmers have a high suicide rate, but I suspect copyeditors, proofreaders, and fact checkers probably have a high rate of getting murdered. God knows the SOBs deserve it.... (I see that you've been busy. And you can take the fact that you don't see my edits very often as a HIGH compliment.)
