There are three main reasons many people avoid buying petroleum (paraffin) products:
Petroleum smoke/exhaust contains many carcinogenic toxins and produces ugly black soot
Petroleum is not a renewable resource and it is of a limited supply
Burning petroleum products creates air pollution and contributes to global warming
Paraffin candles contain up to 11 carcinogenic compounds. These 11 compounds have been deemed ‘toxic air contaminants’ by the State of California. An air quality researcher, David Krause, has documented evidence that candle soot particles contain many of the same compounds given off from burning diesel fuel.

Soy candles are simply better for you, your family, and your environment.
