Soy candles have a number of benefits over traditional paraffin candles. They are made from a renewable resource, soybeans, and are biodegradable, which makes them more environmentally friendly. Soy wax burns cleaner than paraffin wax, producing less soot and releasing fewer toxins into the air. Soy candles also have a longer burn time than paraffin candles and produce a better scent throw, filling the room with a pleasant aroma.
