Implementations of a method of forming a wax ether composition may include: providing a batch of lipids, drying the batch of lipids, and cooling the batch of lipids. The method may also include dosing, with a catalyst, the batch of lipids at 0.1% to 0.3% by weight of the batch of lipids and dissolving the catalyst in the batch of lipids to form a homogenous solution. The method may include adding at least a molar equivalent of a hydrogen donor to the homogenous solution. The method may include sealing and maintaining the homogenous solution and hydrogen donor under atmospheric pressure under reflux until a chemical reaction between the homogenous solution and the hydrogen donor forms a product comprising an ether.
