A nail polish remover is an organic solvent that is used to remove previously applied nail polish from nails. There are many different types of nail polish removers in the market and different brands may have different chemical compositions. The principle ingredients in most, however, are acetone, ethyl acetate or butyl acetate and alcohol.
These chemicals are known to dehydrate the skin, cause irritation to eyes and make nails dry and brittle. They also have a distinct chemical smell and are highly flammable. To counter the dehydration and brittleness effects, many removers also contain conditioning ingredients like castor oil, cetyl palmitate or lanolin.
