Here's why:
* Multiple Components: Nail polish is made up of several different ingredients like:
* Pigments: Give the polish its color.
* Solvents: Help the polish flow and dry.
* Resins: Create the hard, protective layer on the nail.
* Plasticizers: Make the polish flexible.
* Thickeners: Adjust the polish's consistency.
* No New Substance Formed: The ingredients in nail polish are simply blended together, not chemically combined to create a new substance. You can separate some of the components (like the solvents) by evaporation.
Therefore, nail polish is a mixture because it is a combination of different substances that can be separated by physical means.
