Do scented candles soot more than unscented candles?
Although the oils found in certain fragrances may slightly increase the small amount of soot that a candle may produce, a well-formulated scented candle will burn cleanly and will not produce any significant amount of soot. As with any candle, the primary factors that cause sooting are flame instability and a too-long wick, not fragrance or color or wax type. NCA-member candle manufacturers work closely with fragrance manufacturers to ensure that fragrances are appropriately incorporated into candle formulations to result in scented candles that burn safely and properly.
