What is a non essential oil?

Non-essential oils are oils that do not possess the characteristic aromatic qualities or therapeutic properties associated with essential oils. Unlike essential oils, which are concentrated extracts derived from plants, non-essential oils may be derived from various sources and are often used for culinary or industrial purposes rather than for their scent or health benefits. Examples include carrier oils like olive oil or vegetable oil, which are used to dilute essential oils or in cooking, rather than for their own aromatic properties.
