Soy vs. Paraffin
There is an enormous amount of information about the differences in a soy wax candle and a paraffin candle.
Soy wax is considered more environmentally friendly than paraffin wax. This is because soy wax is made from soybeans (a renewable resource), whereas paraffin wax is made from crude oil (a nonrenewable resource).
Therefore, we choose soy over paraffin.
