Vegetable oils are oils that have been extracted from various seeds. The most common include rapeseed (canola oil), soybean, corn, sunflower, safflower, peanut, etc. Unlike coconut oil or olive oil that can be extracted by pressing, these new-fangled oils have to be extracted in very unnatural ways.
No because vegetable oils (e.g. olive, flax, sesame, canola oil etc) contain glycerol. Glycerol molecules give slipperiness and leave a greasy residue when applied to the skin. Essential oils are not greasy (unless mixed with vegetable oil). Vegetable oil is 100% fat but essential oils contain no fat. Whereas vegetable oils are mainly pressed from seeds, nuts, avocados, olives or the bran of grains, pure essential oils are steam distilled (with the exception of citrus oils which are cold-pressed) from plants.
