Benefits of Soy The wax I use are 100% soy wax flakes for all containers and soy blend for pillars, votives, loafs and melts. Why Soy Wax? Soy wax candles burn cooler, more uniformly and last up to 50% longer! No more waste! Soy wax candles burn cleaner and are soot free! Forget those black stains under your kitchen cabinets! Soy wax candles are biodegradable and water soluble.  Spills clean up easily with soap and hot water. Soy wax candles are non toxic and non carcinogenic.  Friendly for the environment! Soy wax is from all natural soybeans...Farm grown right here in the USA!
