Documentations of benefits of soy or hazards of paraffin?

I am new to this forum. I have been making candles since 1997 and switched to soy. I had a newspaper reporter do an article on my candle business. About the same time there was an article done in an Agriculture newspaper in my state on a soy candle maker. Well a lady who owns a candle business (paraffin) wrote me a really "nasty" email. Mostly because my email was posted in the article. Quoting stuff from both articles...(which I didn't agree with a lot what the other one was written about.) She is saying that all the stuff on soy wax isn't true. Well to make a long story short I was wondering if there is a place to find documentation, not just someone saying things on their web page. I have found that yes they burn a lot cleaner than my orginal paraffin ones. I make soy candles mostly from a farmers point of view and it being a renewable resource.
Thanks
