Corn starch or maize starch is the starch derived from the corn (maize) grain. The starch is obtained from the endosperm of the kernel. Corn starch is a common food ingredient, used in thickening sauces or soups, and in making corn syrup and other sugars.[2] It is versatile, easily modified, and finds many uses in industry as adhesives, in paper products, as an anti-sticking agent, and textile manufacturing.[3] It has medical uses, such as to supply glucose for people with glycogen storage disease.

Like many products in dust form, it can be hazardous in large quantities due to its flammability. When mixed with a fluid, cornstarch can rearrange itself into a non-Newtonian fluid. For example, adding water transforms cornstarch into a material commonly known as Oobleck while adding oil transforms cornstarch into an electrorheological (ER) fluid. The concept can be explained through the mixture termed "cornflour slime".
