Thanks DeeAnna!
They're definitely harder this morning, so I'm going to let them sit for a few days and see if they really harden up any more.
I realized after I had poured most of the tubes that I probably shouldn't have done that and waited to test out the recipe first (lesson learned!)...
I just made some lip balm earlier today using (in descending order)
2.5 TBSP Coconut oil
2 TBSP Beeswax
1.5 TBSP Shea Butter
2 tsp Castor Oil
1/2 tsp Argan Oil
just a teeny bit of Vitamin E oil
some lip safe essential oils
I thought putting them in the fridge would harden them up...
