What ingredient is commonly found in nail polish remover?

Nail polish remover is primarily formulated to effectively dissolve and remove nail polish, and the most common active ingredient used for this purpose is acetone. Acetone is a powerful solvent that penetrates the polish, breaking down the chemicals that hold it together, allowing for easy removal from the nail surface. Its effectiveness makes it a staple in both professional and at-home nail care routines.

Besides acetone, other ingredients may be present in nail polish removers for additional benefits, such as moisturizing or nourishing the nails, but they do not serve the primary purpose of removing the polish itself. This characteristic sets acetone apart as the key ingredient in nail polish removers.
