Soy Candles are simply the candles made from soy wax. Soy wax has a lower melting point than other waxes, that is why these candles are contained in candle containers. This makes them called container candles. Soy wax is a processed form of soybean oil. Soy candles are softer than candles made from other waxes but they can also be turned into tower candles by mixing up some other non-soy ingredients in the wax.
