Cornstarch is a common ingredient made from the starchy portion of corn kernels known as the endosperm. It is most commonly used as a thickening agent for gravies, marinades, sauces, soups, and casseroles in cooking and baking. However, cornstarch has many other household uses beyond the kitchen, such as:

• Skin irritation: Cornstarch may be a convenient and cost-effective remedy for skin irritation, though little research supports its efficacy for this use. Many people use it to soothe sunburns and reduce skin itchiness.

• Matte nail polish: To create a matte nail polish, put a few drops of nail polish on a plate and sprinkle a small amount of cornstarch on top. Mix it with a paintbrush and apply it to your nails.

• Milk bath: Cornstarch is one of the secret ingredients in many milk baths, which have historically been used to soothe skin while creating a luxurious bathing experience.

• Silver cleaner: To shine up silver, rub on a thick water-and-cornstarch paste, let it dry, and then buff with a soft cloth.

• Glass cleaner: Spray a thin solution of cornstarch and water on glass, rinse with plain water, and dry for a nice sparkle.

• Wood cleaner: Sprinkle cornstarch dry on wood, and use elbow grease to remove real grease and furniture polish buildup.

• Dry shampoo: Cornstarch mixed with baking soda can be used as a dry shampoo to soak up oil between shampoos.

• Play clay: Cornstarch can be used to make play clay.

• Absorbent: Cornstarch can be mixed with baking soda in drying/deodorizing powder for shoes.

• Egg substitute: Cornstarch can be used as a substitute for eggs in baked goods. Mix one tablespoon of cornstarch with three tablespoons of warm water to replace one egg in a recipe.

It is important to note that many of these uses arent backed by scientific studies, and cornstarch should not be applied to open wounds or used as a natural makeup or oil remover.
