What you’ll need:
1/2 ounce beeswax
2 ounces shea butter
2 ounces coconut oil
1 ounce zinc oxide powder
5 to 7 drops of essential oil (optional)
(1) Place a glass bowl on a pot of boiling water over low to medium heat. This will serve as a double boiler.
(2) Add beeswax, shea butter, and coconut oil into the glass bowl. Stir until all ingredients have completely melted. (Tip: Use a disposable wooden chopstick for stirring if you have it…then you could just throw it away when you’re done.)
(3) When the ingredients are melted, remove the glass bowl from heat. Add the zinc oxide slowly, being careful not to inhale the powder.
(4) Stir in the powder first with the chopstick, then use a mixer or handheld blender until smooth in texture. This will take from about 3 to 5 minutes.
(5) Pour into a glass jar and cool completely before covering.
A few suggestions:
If you would like to add essential oils (I like to use lavender), add a few drops before using the mixer to blend it in completely. Make sure you avoid using photosensitive varieties like lemon, lime, or other citrus oils.
When you are finished mixing and have poured the sunscreen into your container, wipe off all the excess from your mixing bowl and mixer with a paper towel before washing. The first time I made a batch, I immediately left everything in the sink for washing later. When I came back after an hour, it was nearly impossible to wash off what was left with a soapy sponge. Lesson learned.
If you live in a warmer climate, the mixture will result with a more runny consistency when kept at room temperature. To avoid this, you may lessen the amount of coconut oil or increase the beeswax. You might need to play around with the amount until you reach your desired consistency.
