Acetone is commonly used in nail polish remover due to its effectiveness at breaking down the chemical bonds in nail polish, making it easier to remove. It is a powerful solvent that quickly evaporates, which helps in efficiently cleansing the nails without leaving a greasy residue. Acetone is preferred for its speed and effectiveness, especially for removing stubborn or gel nail polishes.

In contrast, alcohol is also a solvent but is not as effective as acetone for this particular purpose. Hydrogen peroxide is primarily used for disinfection and has no significant role in removing nail polish. Formaldehyde is a chemical often associated with nail hardeners and preservatives rather than removers. Thus, acetone is the most suitable choice for nail polish removal.
