If you're using scent in any candle and burning it, you've got pollutants, I imagine. And if you're burning a soy candle, where do you think the smoke goes? If there's concern, I wouldn't burn a scented candle, to start. Nor use any scented or chemical cleaners that you spray in the air. Or incense. I think people are more aware of the concern over anything inhaled, whether it be the fumes from scented candles, cleaners, freshners, etc. In addition, there are more sensitivities due to allergies, too, and people are making (semi) educated decisions on what they use in the home. Surely there are people that won't burn candles, or stick to plug-ins, wickless, etc. and some just simply don't care. Or the in-betweens that have minimized their usage of burning scented products. I wouldn't use that in a promotion for selling soy v parry, especially if you're using scented oils in the soy, but it is definitely something to be educated on and prepared to answer questions about if you are selling candles.
