For more information, you could contact Clenzoil at
www.clenzoil.com and request (there's a link on their home page) a copy of their Material Safety Data Sheet (MSDS), which will include a variety of information about the toxicity (or lack thereof, I guess) of the product. They're required by law to have an MSDS, and to provide it to you.
It's also a good idea - after doing the EMS, doctor, hospital thing of course - to contact the manufacturer of any potentially toxic chemical if you've been exposed. They should have someone on staff trained to provide information about the product in case of emergencies involving it. My best shooting buddy had that job at a major chemical supplier - he had emergency information for about 7,000 chemicals literally at his fingertips.
