As a 100% natural wax, soy wax contains none of the pollutants that may be released into the air when burning other waxes, and additionally, it produces less soot. This makes for better indoor air quality, which is especially great for people with respiratory conditions or allergies. Soy candles burn cleaner and are made from a renewable resource (soybeans), making them a more environmentally friendly choice compared to traditional paraffin candles, which are derived from petroleum.
