Roma~ I am not getting into the whole soy vs. paraffin thing but I have been using a blend of paraffin and soy for many yrs and I do not have any health problems. I used 100% paraffin before that. Believe what everyone is telling you about the FO's.....think about it, you are heating a liquid that is emitting a scent into the air, even though it smells good there are certain toxins in it that can cause harm if you are not in a well ventilated area. As with anything....cleaning solutions....do you clean with straight bleach in a closed room and does it burn your eyes? YEA! Is it good for you to breathe? NO. As for cancer with out smoking......ya know there are millions of kids under the age of 4 who have cancer and I dont think they have ever smoked. Not to mention they are not candle makers either. People will tell you anything these days to make money. How do you know this man actually has cancer??? Was he on a respirator? What did he do to convince you that he had cancer other than just letting you know? This is not sarcasm it is simply stating the obvious.
