Effects of Candle Burning to Indoor Air Quality
An internationally funded study on candle emissions performed in 2007 has confirmed that well made candles of all major wax types pose no discernible risks to human health or indoor air quality.
In carrying out the tests, reference candles made from paraffin, soy wax, stearin, palm wax and beeswax were burned in a specialized testing chamber. Emission gases were analyzed for more than 300 chemicals known or suspected of toxicity, health risks or respiratory irritation at elevated concentrations.
The study found all of the waxes burned cleanly and safely, with no appreciable differences in burning behavior. Their combustion byproducts were virtually identical in composition and quantity, with all emission levels registering far below the most restrictive of any applicable indoor-air standards.
