Soy candles are a great alternative to traditional paraffin. They’re made from soybean oil rather than crude oil so are much more earth friendly.
Since soy candles are plant based they are also an excellent alternative to beeswax for vegans. Soy candles are safer because they burn at a lower temperature, there is little to no soot and they’re biodegradable.
Another bonus is that they hold more scent! Soy wax costs a little more but I think they're worth it and I have fun making them.
