Yes, Carnauba wax is a great alternative to beeswax. It's obtained from of a species of sustainably grown palm known as the “Tree of Life” or Copernica cerifera. The wax is derived from the leaf of this tree, and harvesting is done via manual pruning once a year, allowing the tree to continue growing for decades. Another vegan options is soy wax, which can be used in a 1:1 ratio for beeswax in this recipe.
