Combine the coconut oil, shea butter, and beeswax in a double boiler. You can also use a glass bowl over a smaller saucepan filled with a few inches of water.
Bring the water to a boil and stir ingredients until melted.
Remove from the heat and add the zinc oxide powder, vitamin E oil, and essential oils. More zinc oxide gives you more sun protection, but it also makes a thicker layer on the skin.
Pour into your molds or tubes and allow to cool completely.
Store at room temperature or in the fridge. Keep below 80 degrees or they'll start to melt.
Notes
You can use different shaped molds for different designs or use a square baking pan and cut them into bars.
You can use any amount of shea, cocoa, or mango butter you want as long as they total 1/2 cup.
Experiment with how much zinc oxide you need to use for your skin type and sun exposure needs.
