Soy wax is made from environmentally friendly, renewable resources, soy wax also burns slower than paraffin wax, meaning you get a candle that lasts longer.  While all candles emit some black soot while burning, candles made from soy wax burns cleaner and results in less soot. Another reason to choose soy wax when it comes to candles is the fact that soy wax is an excellent fragrance carrier that does not require chemical amplifiers.  The result is a well-balanced true to scent candle.
