I never use beeswax with leather; it makes leather waterproof but sooner or later crispy too when drying back to wax mode. Lanoline mixed with biobased greases is my option when working with leather.

My own mix to wood is 3/5 Carnaubawax with 1/5 Beeswax and 1/5 Pine Turpentine. You could add some boiled lenseed oil too. Warm all in tin can which swimming in boiling water. When all wax has melted and mixed to solvent take the can awy and let it cool of. Wax is ready to use when turpentine has vapoured of. This is hard wax which I use as a tread over Danish Oil impegrated wood items.
