Combine the beeswax, jojoba oil, and mango butter in a double boiler or medium sized stainless steel bowl set inside a large pot with hot water.

Melt the beeswax and mango butter in the oil until just melted. Remove from the heat and set aside.

While the oils are slightly cooling, mix the magnesium chloride salt with the warm water until fully dissolved.

Pour the warm oils and the magnesium chloride solution into the mason jar. Add optional lavender essential oil.

Using a handheld blender, emulsify the oils and water. I suggest placing an immersion blender on the bottom of the jar and blending continuously for 30 seconds. Then, slowly raise the blender through the mixture while it is still blending (be sure to hold the jar with the other hand!).

When you reach the top of the mixture, turn off the blender. Repeat every 5 minutes until the mixture is cooled and turns white. I usually do this 3-4 times total. Hint: It's a bit like making homemade mayo!

Spoon the lotion into a lotion jar.

This luxurious magnesium lotion is shelf-stable at room temperature and lasts for months. If slight separation occurs over time, simply remix with a small whisk or spoon.
