Re: OTO R-0600 ...I read the words "contains chemicals known to cause cancer" right on the top of the label. The term carcinogen used in this thread discussing it's relative harmlessness compared to household chemicals. Is there any data supporting to what level it is potentially dangerous?
Suspected carcinogenic with ingestion or
repeated skin contact. (I don't mean getting a drop on your skin once in a while.) Then again many household chemicals fall into this catagorry also (and some are known carconogens! Just check some of the labels in your garage, particularly solvents, paints, etc!)
Remember, it says "contains chemicals known to cause cancer...". It doesn't say about what concentration they cause cancer or the amount of contact needed or mode of ingestgion.
For that matter, grilling over charcoal can make food cancer causing by creating free radicals but that doesn't slow down all the avid grillers we have! (This is nothing new and has been known since about the 60's!)
Just consider the words on the label a warning to use common sense when using the reagent.
Here is a link to an OTO MSDS, it is NOT listed as carcinogenic.

Also, realize that just about every aniline derivative is a carcinogen or suspected carcinogen (This includes DPD and also permanent hair color!), as are the closely related tolidines (which are methylanilines)!
