What is the active ingredient in fingernail polish remover?

Answer by  SMJ (72)

There are acetone and non-acetone based nail polish removers. The active ingredients are acetone and ethyl acetate, respectively. Neither are very toxic, but both are volatile and flammable, particularly acetone.

Acetone is the main active ingredient in nail polish remover. Acetone is harsh and should only be used on nails, otherwise could cause poisoning.
