Do Scented Candles Burn Differently Than Unscented Ones?

No, A well-made scented candle - like an unscented
candle - produces harmless water vapor and carbon
dioxide when burned.

The only difference with a scented candle is that a fragrance
is released as well. Reputable candle manufacturers
carefully monitor the addition of fragrance to ensure a clean
and proper burn.

There is a maximum amount of fragrance
that can be added to a candle before it will no
longer burn cleanly or properly.
