Soy candles are a better alternative to paraffin wax for several reasons. First, soy wax is naturally derived from the oils of the soybean, making it a sustainable alternative to petroleum which is the source of paraffin. Second, soy wax burns more cleanly than paraffin, which means a more controlled flame height (safer to use), and less soot and smoke (safer to breathe). Third soy wax releases fragrance oils better than paraffin, which means a nicer aroma in your home. ACDC candles go through extensive testing to ensure a full release of fragrance, minimial amount of soot and smoke and a controlled flame. This testing ensures that you're buying quality and safety.
