Unsaturated vegetable oils tend to be liquid at room temperature, but they can also be 'hardened', through a chemical process called hydrogenation, to make them solid at room temperature.

Why are vegetable oils hardened?

How do you harden oil?
HydrogenationDuring hydrogenation, vegetable oils are hardened by reacting them with hydrogen gas at about 60ºC. A nickel catalyst is used to speed up the reaction. The double bonds in the vegetable oils are converted into single bonds. This is the way unsaturated fats can be made into saturated fats.

Is vegetable oil high in polyunsaturated fats?
The lipid composition of plant-derived oils differ depending on the source. Some plant oils contain more saturated fat than unsaturated. These include palm oil, palm kernel oil and coconut oil. Other oils, such as sunflower and soybean oil contain mainly polyunsaturated fat and canola and olive oil is rich in mono-unsaturated oil. Margarine is produced by partially hydrogenating the unsaturated fats, to make them more solid, so part of the health benefit of these oils is then lost.
