Soy wax is a natural product derived from vegetables -  soybeans!  This makes soy a 100% biodegradable, renewable resource offering a longer, cleaner burn than  paraffin wax -  a refined gasoline by-product.  It is therefore no mystery why soy offers little to no soot and burns much cleaner - reducing air pollution in your home by as much as 90%!  You can feel safe in knowing your Driftwood Soy Candle is safer for your health and family.
