The chemical formula for cornstarch is C27H48O20. Cornstarch has a molecular weight of 692.6 grams/mol and represents the starch obtained from the corn kernel. Cornstarch is often used in the food industry and in the manufacturing process of bioplastics.

The process used to manufacture cornstarch requires steeping the corn for several hours, separating the starch, drying and modifying it if necessary. Because cornstarch has thickening properties, it is used to increase the consistency of various foods, such as soups and sauces. Data from the U.S. Food and Drug Administration indicates that cornstarch is not currently considered a potential health hazard when used in reasonable amounts. Cornstarch is also used on medical products such as gloves due to its anti-stick properties.
