I think everything causes cancer! LOL I think that if you make the "candle" with a low enough amount of fo and no color then what is the difference between that and B&B product? But then I ask why call it a candle because as far as I know people want a candle for the fragrance. IMO you can't put the two together and have it be safe. I have had some people ask me if you can use my candles as a lotion I always say no. like I said though JMO. Heather
