Prepare your molds. I make 8 smaller bars or 7 larger bars using my muffin tray.
Place the shea butter, beeswax (or candelilla wax), and coconut oil into your heatproof bowl and place it into a saucepan filled with about 5 cm (2 inches) of hot water that is sitting over a medium-low heat.
Make sure that none of the water from the saucepan gets into your oils.
Gently stir until the ingredients have completely melted into a liquid and combined. Don't leave it sitting on the heat any longer than needed, as you don't want it to get too hot otherwise it could reduce the efficacy of the ingredients.
Remove the bowl from the saucepan and dry off the water from the outside of the bowl so it doesn’t drip onto your work surface and lotion.
Leave the oil to cool down for 5 mins, then stir in the vitamin E.
Pour the lotion into your molds then add 10-12 drops of the essential oil into each of the 7-8 bars and stir it through using a kebab stick. If you add the essential oil when it is too hot, it will just evaporate and lose it's scent, so I tend to add it once I've poured them into the molds as it is cooler by this point.
Leave the bars for a few hours to become firm. Before removing the bars from their molds, refrigerate them for 30 mins, as it makes them firmer and easier to manage.
