Some people use crayons to melt down for candles or just a bunch of the end left over pieces of old candles. I have been looking at goats milk candles recently since we have 7 nannies in milk right now. Still need to use some type of wax with the goats milk but it works like the coconut oil to hold oils and scents but the good thing is it cuts back on the amount of your wax need allowing you to make more candles out of the same amount.
