You see one reason I do not take any of these "articles" into consideration is this: It is strictly a matter of the authors opinion. If the author believes soy wax to be "safe" well you can bet your bottom dollar that he is going to publish an article that is at least subliminally biased. IF Paraffin was so dangerous than we would not be allowed to sell it. Or we would have limitation on who we sell it to like alcohol. So that is why I don't exactly take into consideration, the .gov sites either. Heck if the government thought it was dangerous, you can BET they would put limitation and taxes on it! I think the soy wax thing is like organics. It is a matter of belief and lifestyle. It's a fad IMO. Some peeps will believe ANYTHING written down or published. And everyone loves a controversy. I agree with Chad, not only do you have to take into account the fuel used to harvest and extract the components of the soybeans, but there is also shipping it. On another note, I have gotten a couple of candles from some very impressive and accomplished soy makers, and both of theirs smoked and sooted. I did not marathon, or do anything out of the ordinary. Yet they smoked more than my paraffin candles. Just a thought.
