Lotion 2 absorbed 3 Milliliters and Lotion 1 absorbed 2 Milliliters. Analyze your graph.
Same recipes will call fir liquid oils while others will require solid oils or butter, and there are many oils to chose from: avocado coconut, shea and olive oils.
Of course everyone wants to know; especially woman.
