Essential oils are distilled from the leaves, bark, roots and other aromatic portions of a botanical. Essential oils evaporate and have a concentrated aroma. Carrier oils, on the other hand, are pressed from the fatty portions (seeds, nuts, kernels) and do not evaporate or impart their aroma as strongly as essential oils. Carrier oils can go rancid over time, but essential oils do not. Instead, essential oils “oxidize” and lose their therapeutic benefits, but they don’t go rancid.
Vegetable Oils are Also Known as Carrier Oils or Base Oils
The term carrier oil is generally limited to use within the practice of aromatherapy. In natural skin care, carrier oils are typically referred to as vegetable oils, fixed oils or base oils. Not all fixed oils/base oils are vegetable oils. Emu oil (from the emu bird) and fish (marine) oils are also classified as fixed/base oils, but these animal-based oils are generally not used for aromatherapy work.
