cornstarch for hands

Cornstarch, also known as cornflour or maize starch, is a fine, white powder derived from the endosperm of corn (maize) kernels. It is produced by wet-milling corn kernels to separate the starch from other components, then drying the extracted starch to a powder. Cornstarch is nearly pure carbohydrate (approximately 90% starch) with minimal protein, fat, or fiber.\n\nWhen applied topically, cornstarch absorbs moisture and reduces friction on skin. It has a smooth, silky texture and remains stable at room temperature. In culinary contexts, cornstarch is distinguished from cornmeal (which retains some bran and germ) and corn flour (finely ground whole corn).

In the kitchen, cornstarch is primarily used as a thickening agent for sauces, gravies, puddings, and stews. When mixed with liquid and heated, its starch granules gelatinize, creating a smooth, glossy finish without the opacity or flavor of flour-based roux. It is particularly valued in Asian cuisines for velveting meats and creating silky sauces. Cornstarch is also used in baking to create tender cakes and pastries, and as a dusting powder for work surfaces and pastry to prevent sticking. Home cooks sometimes use cornstarch on hands as a gentle drying agent before handling dough or pastry, helping prevent sticking without the greasiness of flour.
