Soy Candles

The main difference is that, instead of the regular paraffin wax, they are made from a special kind of wax known as soy wax. Soy wax is actually soybean oil that has been hydrogenated.  At that time, there was an increasing demand for candles that are natural.  At present, soy wax is available in both pellet and flake form. As with regular paraffin candles, these candles can be molded in different shapes and sizes, with a variety of designs.
However, they also differ from regular candles in several ways.  This is a good property for candle makers, as this property makes soy wax an easier medium to work with and to mold. When placed in direct sunlight, they can end up melting and the wax can become unstable.
