Is cornstarch and corn muffin mix the same thing?

* Cornstarch is a fine, white powder made from the starch of corn. It's primarily used as a thickener in sauces, gravies, and desserts.

* Corn muffin mix is a pre-made blend of ingredients, including cornmeal, flour, sugar, baking powder, and sometimes other items like buttermilk powder, that is specifically designed to make corn muffins.

While both contain corn products, they have distinct properties and uses.
