What is the difference between Fatty oil vs essential oil?

Fatty oils, also known as carrier oils, are derived from the fatty portion of plants or nuts and are used to dilute essential oils for topical application. Essential oils are highly concentrated plant extracts that are volatile and aromatic, often used for their therapeutic properties in aromatherapy and natural health care. Fatty oils provide a base for essential oils, whereas essential oils are typically the primary source of aroma and therapeutic benefits in various applications.
