Scented candles are used by many to cover the unpleasant smell in our home. Others use it to create a relaxing environment to de-stress after a long and tiring day of work. However, one of the problems with this type of candle is its fragrance. Anne Steinemann, an expert in terms of environmental pollutants and a professor at the University of Melbourne, there are several waxes that release various kinds of possibly toxic chemicals like toluene and benzene. These harmful substances could damage the lungs, brain, central nervous system and various difficulties in development.
The expert added that there are some people who cannot even go inside a scented candle store even if they are not lit. These wax release so much scent that could cause asthma and migraines. In South Carolina State University, researchers tried candles made of vegetable-based wax and paraffin wax based on petroleum and those that have no scent, dyes, and pigments. The report summarized that the vegetable-based wax did not emit toxic substances. However, they found out that paraffin-based wax emits unwanted substances. The report further states that a person who burns candle each day for several years could develop a higher risk of allergies, asthma, and even cancer. This is, however, refuted by the National Candle Association. According to the group, scented candles are supported by decades of studies, testing, and a long history that it is safe to use. There were also safety and health research made for various fragrance components that are used in wax. This includes dermatological and toxicological testing.
