Soy wax candles come from soybeans, unlike paraffin wax. In addition to being organic, soy wax have a longer burn rate because of their chemical structure. There is also no soot when you burn a soy candle, usually, a white smoke comes out when you put the candle out and that's it.
We only use 100% soy wax while some companies use a combination of soy and paraffin. We have tested different types of soy waxes out there and found the best one that we, ourselves, will want to light every day.
