While synthetic fragrances are made in a laboratory, natural essential oil isolates are created by isolating one of the natural aromatic compounds from a complex scent, for example, that of an orange, a rose or a particular species of lavender flower. These single natural essential oils scents or "constituents" are called isolates.
A natural isolated is a single chemical, isolated from a plant, that has a particular very exacting smell. It is a part of something real rather than man-made from another material or animal by-product (very common in the perfume industry). Hawaiian Healing Skin Care takes immense pride in sourcing only natural essential oil isolates to make our perfume.
Natural fragrance oils are blends of isolatge4s that are extracted through the same processes that are used to get essential oils. The difference is that: When you extract an essential oil you are extracting the entire scent complex compound containing ALL constituents.
In closing, when you extract a natural essential oil isolate you are extracting a single scent molecule or single constituent.
