Olea Europaea (Olive) Oil Unsaponifiables
Using hydrogen gas and high pressure, plant oils can undergo a hydrogenation process whereby they change from a liquid into a solid or semi-solid state - becoming hydrogenated oils. The hydrogenation process allows oils to remain solid at room temperature - an everyday example of which is margarine. Unsaponifiables are the components of an oil that fail to become saponified in the refining recovery of fatty acids. Unsaponifiables can be useful in balancing a formulation, as an emollient, or as a moisturising ingredient.
