Soy wax, which comes from soy beans doesn't contain pollutants, like paraffin wax. Soy is biodegradable. There is a considerable reduction of soot emission. Clean up of Soy can be done with soap and water, so containers can be reused. Soy wax burns completely, unlike paraffin wax which leaves wax at the bottom of the container. Soy wax burns at a cooler temperature therefore throwing a stronger scent. Soy wax helps support American Soy Beans Farmers.
