What is the main ingredient in traditional nail polish remover?

Ethyl alcohol
Acetone
Isopropyl alcohol
Oil

The correct answer is: Acetone

The main ingredient in traditional nail polish remover is acetone. Acetone is a powerful solvent that effectively breaks down the polymers in nail polish, allowing for easy removal without excessive scrubbing or rubbing. Its effectiveness is due to its chemical properties, which enable it to penetrate and dissolve even the most stubborn nail polishes. This makes acetone the preferred choice in nail care products specifically designed for removal. While ethyl alcohol and isopropyl alcohol can also serve as solvents, they are not as effective as acetone for this particular purpose. Oil, meanwhile, is not a solvent and does not serve to remove polish but may actually help in moisturizing nails and cuticles. Understanding the role of acetone in nail care is essential for practicing professionals, as it highlights the importance of choosing the right products for different tasks.
