The essential oil absolute is most commonly used in the fragrance industry, but has recently become an aspect of aromatherapy as well. The scent of absolutes can invoke powerful feelings and emotions from individuals. Aromatherapy absolutes are much like essential oils, because they are both extracted from plants. However, the method used during the extraction process is much different from that of the essential oil. Also, these are heavier oils, so be aware the container may not look "full". All of The Oil Shop oils are sold by weight, not volume.
