The DIFFERENCE in wax is the HOT THROW, which is how STRONG the scent will be when burning the candle.
SOY CANDLE is made with natural soy wax that has a cleaner burn MILDER HOT THROW.
PARA-SOY CANDLE is majority soy wax with a percentage of paraffin wax, which has a STRONGER HOT THROW.
NEVER touch the candle tin while lit. If the tin seems too hot, or if you see smoke coming from the wick, extinguish the candle immediately and let it fully cool before touching it.
