Combine the beeswax, shea butter and coconut oil in a microwaveable container and heat for 30 seconds at a time in the microwave until the beeswax is completely melted. Stir in between each heat burst.This process could also be done in a double boiler.
Mix in your non nano zinc oxide.
Make sure to mix it thoroughly.
Carefully pour into the containers.
As it cools down, continue to stir to help mix all the zinc oxide through.
Let sit until completely cool and firm, about 6 - 12 hours.
