Soy wax is a vegetable, plant based wax made from the oil of soybeans. It has a lower melting point than traditional waxes. It burns slower, cleaner and produces less or no soot at all while burning. Since soy wax is softer, candles made with soy are usually container candles. They could be made into free standing pillars and votives if paraffin wax and certain additives are mixed into the wax, but then you will not be burning a natural candle. Soy based candles are non-toxic, making them better for both the environment and your health. It is biodegradable and is a fully renewable resource.
