One item that can be found in almost any home is a simple scented candle. Not only do they work well to help mask any unusual odors in the home, they can also create a very intimate ambiance. Recent research has shown, however, that scented candles may have hidden dangers and the harm they cause may easily outweigh the good they provide.
This study was done at the National Center for Atmospheric Science at the University of York by a professor, named Alistair Lewis. According to the research, one of the ingredients that was commonly used to give scented candles their scent transforms into high levels of formaldehyde.
Linonene is the compound in question and it is often used for citrus scented candles to produce their unique aroma. It is considered safe at the time that is added to the candles. As a matter of fact, it is considered so safe that it is often used for flavoring foods and to produce a lemony scent in air fresheners.
Despite its apparent record of safety, it does react with ozone when it is released into the air. When that occurs, 50% of the limonene molecules mutate into formaldehyde. This brings about two different concerns that Prof. Lewis pointed out.
Limonene was found in higher concentrations in scented candles than was estimated previously. Additionally, homes tend to be built to higher standards so there is less air exchange, allowing the formaldehyde to linger in the indoor atmosphere. This creates a toxic environment and can cause long-term health problems.
Formaldehyde is listed as a possible carcinogen by the Health Protection Agency. It is also corrosive and toxic. Some of the issues that may be associated with exposure to formaldehyde include sore throat, coughing, nosebleed and stinging eyes.
Limonene is described as a bulk chemical that is usually included at higher concentrations when the product is less expensive. Some of the highest concentrations can be found in air fresheners, floor cleaners and scented candles.
The professor went on to say that the best way to combat an issue with formaldehyde inside of the home is to open the door or window to allow air exchange. It is especially important to do this after spraying air freshener or using a scented candle.
Something else that you may want to consider doing is avoiding using scented candles in the first place.
