I'm making some tarts with the Ecosoya pillar blend wax and have found 3 different fragrance loads. One site says 6% max, one 5-12% max and one 6-9% max. I obviously want my tarts to smell as much as they can so I want to use the max allowed but with this conflicting info I'm confused. Anyone use this wax for tarts and have any input as far as FO load? Thanks everyone!
