A. Scentsy uses a food-grade petroleum based wax. Scentsy’s food grade petroleum wax is the same wax they spray on apples in the grocery stores, to give them their shine. Scentsy chose this wax because of its superior scent loading ability, melting point and firmness. Scentsy looked at their waxes, but could not find a good quality vegetable based wax that held the scents. The type of wax we use is a not an issue, with regard to the chemicals released while burning any traditional wicked candles, including tea lights. Scentsy Warmers only warm the scent out of the wax - the wax remains in the warmer, thus there is no danger of chemicals being released into the home. You will end up with a piece of non smelling wax that you dispose of and replace with a new Scentsy candle bar. No wick, no match, no flame, no soot, no smoke, and no wax evaporation!
