Soy candles are made from soybeans, which are a natural and renewable source. All the soy used in Mallory's Candles are grown in the U.S.A supporting American Farmers.
Paraffin candles, on the other hand, are made from petroleum, which is not a renewable resource and also contains carcinogenic substances. These can be released into the air during the burning process and can lead to breathing problems later on the more often you burn these candles. Do you know what else is made from petroleum? Your car tire! Would you want to burn your car tire in your home?
