Why Does Fingernail Polish Stink?

Nail polish is a beauty staple that has been used for more than 100 years, and while its chemical makeup may have changed over the years, its characteristic smell has not.

Components

Nail polish is made from several chemicals, mainly ethyl acetate, formaldehyde and toluene, all of which have their own distinctive smells.

Ethyl Acetate

Ethyl acetate is a solvent used in both nail polish and nail polish remover, and has a fruity odor. The smell of ethyl acetate is the one most associated with nail polish.

Formaldehyde

Formaldehyde is a nail hardener added to certain types of nail polish. It has a strong, pungent odor, often described as suffocating.

Toluene

Toluene is used to thin nail polish and has a sweet, piercing smell.

Warning

Many of the chemicals used to make nail polish are potential health hazards, particularly toluene and formaldehyde. To minimize your risk, always apply nail polish in a well-ventilated area.
