Soy wax is a natural vegetable oil made from the oil of soybeans. Soy's greatest advantage is that it is completely renewable. It is also eco-friendly, carbon neutral, sustainable, and American grown. Soy wax is non-toxic and burns cleaner than paraffin, with no petrol-carbon soot, which can blacken walls, ceilings, and furniture; as well as contaminate ventilation ductwork in your home, and add toxic carcinogens into the air you breathe.
