Soy wax is made of pure botanical oils and soy bean base.Soy candles are very clean burning (no soot) and known for their long burning times. Containers can be easily cleaned with soap and water if you would like to reuse or recycle them. Spills also clean up in a snap. Because some of the scents are not approved for use on skin please only use the wax to burn. Please keep away from small children.
