“If I pay for jasmine absolute, I should get jasmine absolute”, said Mark in one of our early meetings. He had gathered a small group of us to discuss the never-ending problem of essential oil adulteration. ”And the same goes for any oil we buy,” he continued, “we want the best quality. Let us do our own perfumery. Don’t dilute the stuff for us.” It doesn’t help that Mark’s demands exceed the generally accepted standard that he has a tendency to be paranoid.  ”We know that the majority of the oils out there are adulterated, but we really want to make it clear to the suppliers: give us the real thing and we’re prepared to pay for it. But if you lie to us, we’ll name and shame you.” At this point our essential oil buyer cut in: “We already have them sign a declaration. Naming and shaming might mean that we could be left with no suppliers.”
