SOZO Candle Company proudly uses 100% soy wax for both ClassyStache and Borderland. Soy wax is a natural and renewable resource derived from soy beans. Many candle companies use paraffin wax which often creates a significant amount of black soot that collects on candle jars, walls and other surfaces within your home. Paraffin is derived from petroleum and contains 11 carcinogenic toxins which are released when burned. Our 100% soy candles are eco-friendly, renewable, American grown, sustainable, carbon neutral, and actually burn 50% longer then paraffin candles.
