What does this michelia leaf oil look like — appearance, color and consistency?
This michelia leaf oil is a clear to pale yellow mobile liquid, with a pale yellow to light yellow-green colour in a fresh batch. It is thin and free-flowing, typical of a linalool-dominated leaf distillate. The colour may deepen slightly with age or light exposure — a natural oxidation sign that does not affect the linalool content within the stated 36-month shelf life.
