Using a double boiler (or in my case, a pot of water with a bowl sitting inside), melt together the shea butter, coconut oil, beeswax and olive oil.
Once they are all melted, add in the non-nano zinc oxide, and whisk it in really well.
Add your essentail oils of choice and mix them in.
Now at this point I like to stick it in the refrigerator to speed up the hardening process. I go by every now and then to whisk it up to make sure the zinc oxide doesn't settle on the bottom. If you put it in the fridge you just can't forget it's in there. I take it out when it is mostly hardened, but still a little soft. Then I whisk it, and that gives it a lovely divinely fluffy texture! But you can totally do this by leaving it out on the counter, it'll just take a lot longer.
I store it in several little half and quarter pint jars so they are easy to take around with us.
