I am a paraffin candle maker with my 3 year old son in the house while I constantly burn test candles. Usually I have one in every room - including his. No, I'm not worried one bit about it because I've done my homework. I refuse to believe something someone else says without doing my own research. Have you ever heard of anyone getting lung cancer or other diseases from burning candles in their home? Let's take these in order: There's a reason 99% of candles are made with paraffin. It's a very old medium for candle making and, in general, paraffin throws better than soy. Also, refining soy wax uses the same chemicals and processes as paraffin refining. Burning these candles in your home, is the same as burning diesel fuel or pulling a car into your home - to a much lesser extent. You breathe 100,000 times more carcinogens in a 30 minute rush-hour commute than you would if you burned a candle right next to you 24/7 for a year. Yes, soot does travel deep into the lungs. DUH! Anything you breathe does that. What they don't tell you is that any candle will soot if it's not wicked properly and/or the wick isn't trimmed. "Significant quantities" does not mean dangerous quantities. Significant is the next level above "Trace". If paraffin candles were so toxic, don't you think they would have been banned by the EPA? "The soot from these materials contain not only carcinogens, but neurotoxins and reproductive toxins." Yes, they do but the amounts are extremely small. See point #2 above. "Burning paraffin candles can emit small amounts of toxins into the air." -- See all points above. They're just rewording the same thing over and over again.Now, on a positive note: Soy helps support American agriculture. Parrafin candles are a major consumer of the oil refining process waste which would otherwise end up in land fills.Why can't soy and paraffin stop bashing each other and live in peace?
