If the term "nature identical" is confusing to you, we understand! How can something man-made, be identical to nature? Technically they can be, if you consider the vitamin industry, these are typically man-made products designed to replicate the vitamins found in naturally grown food.
For the cosmetic industry, a new branch of man-man's are being introduced, called 'natural identical' oils. According to the manufacture of this vanilla oil it is a blend of, "natural and natural identical ingredients which are compounded to create the true scent of vanilla at a fraction of the cost." This means the scent is achieved by mixing pure EO's with other aromatic compounds. If you are a purist who use only EO's, this product wouldn't be your go-to-scenting oil, but if you currently use "fragrance oils" -- this scent blend would be a step in the more natural direction.
Typically I can smell the alcohol-y notes within a true vanilla absolute, but this oil (since it isn't an absolute) holds none of that, its only sweet, smooth vanilla.
INCI: Fragrance Oil
This is a proprietary blend of scents, please do not ask for the formulation. The FDA ruling on fragrance and essential oils within cosmetics is that they need only be listed on an ingredient panel as "fragrance oil" to protect the manufactures formulation.
