Scented candles are safe. The safety of scented candles and the fragrances they contain is backed by decades of research including toxicological and dermatological testing which confirms safe use.
Recently, the National Candle Association has identified news reports about candles that needlessly cause concern by crediting unsubstantiated science. The misleading information presented is often based on a scientifically incorrect interpretation of studies; studies which in themselves, used questionable testing methods and therefore led researchers to incorrect conclusions; and information that is presented completely out of context. Contrary to these erroneous reports, there have been many accurate studies conducted under scientific conditions that can be reproduced, showing no negative health risks associated with the materials used in properly manufactured candles.
The most extensive and rigorous scientific investigation of candle emissions to date has been an internationally funded study conducted in Germany in 2007. This study reconfirmed that major wax types used in candles — paraffin, soy wax, stearin, palm wax, and beeswax – all burn cleanly and safely and pose no discernible risks to human health or indoor air quality. These independent laboratory tests analyzed candle emissions for more than 300 chemicals and compared them to known, relevant indoor air standards, and found the candle emissions to be far below the most stringent of applicable air standards.
The candle industry is acutely focused on safety and continues to participate in research on the safety of its products. Individuals with questions about candle safety are encouraged to contact the National Candle Association at email@example.com.
