Corn oil is made by pressing or extracting seedlings of Zea mays L. (Gramineae) and then refined. Corn oil is a transparent, pale yellow to golden yellow oil with a subtle scent and taste. It is used in the food business to make certain foods (margarine, mayonnaise, dietetics, baby food), as well as in cosmetics to make soaps and hair care products. Corn oil is also used in the technical industry as a basic material for lubricants and leather care products.
