What ingredient in nail polish remover can be drying to nails?

Acetone is the ingredient in nail polish remover that is known for its drying properties. It is a powerful solvent that effectively breaks down the polymers used in nail polish, allowing for easier removal. However, acetone is also quite harsh on the nails and surrounding skin, which can lead to dryness and potential damage over time. This is especially important for individuals who use nail polish remover frequently, as repeated exposure to acetone can strip the natural oils from the nails and make them more brittle.

Ethyl acetate, while also a solvent used in some nail polish removers, is generally considered to be less aggressive than acetone. It can still cause some dryness, but it is often used in products intended to be gentler on nails. Isopropyl alcohol primarily serves as a disinfectant rather than a solvent for nail polish, and while it may have some drying effects if used excessively, it is not as commonly associated with nail polish removal as acetone. Formaldehyde is not an ingredient typically found in nail polish removers and is more often linked to other cosmetic applications such as preserving certain formulations.
