How to Recycle Nail Polish/Remover
Nail polish, acetone and non-acetone removers, and related cosmetic solvents. Small volumes, but genuinely flammable and not drain material.
Quick answer
Both the polish and the remover are household hazardous waste, and programs such as King County take them as a pair. Acetone is genuinely flammable rather than nominally so, with a flash point around 0 degrees Fahrenheit. A used cotton ball can dry and go in the bin; bottles of either go to a collection site, never down a drain.
- Recyclable
- Not curbside
- 1Keep bottles closed and upright, since evaporation is what makes the vapor hazard
- 2Let used cotton balls and pads dry out fully in open air, then bin them
- 3Take bottles of polish and remover to household hazardous waste together
- 4Pass unwanted but usable polish to someone who will use it, or a salon or theatre group
- 5Never pour remover down a sink, toilet, or storm drain
- 6Keep it away from heat, flame, and pilot lights, including while using it
- 7Work with ventilation, since the vapors are heavier than air and pool in small rooms
- Household hazardous waste facilities
- Municipal collection events
- Salons, which handle solvent disposal commercially
Acetone is classed as a Class IB flammable liquid with a flash point around 0 degrees Fahrenheit, meaning it gives off ignitable vapor well below room temperature, and the National Fire Protection Association names nail polish among common household flammable liquids. That is why the advice is about heat and ventilation rather than only about disposal. Non-acetone removers substitute other solvents and are flammable too. On disposal, King County accepts both nail polish and nail polish remover as household hazardous waste, which is the pattern most programs follow. Small residues on cotton or tissue are treated differently and can be dried and binned, because the solvent evaporates rather than persisting.
The volumes here are small, so the realistic harm is local: solvents poured down a drain pass through treatment poorly, and the vapor is a fire and inhalation risk in an unventilated bathroom. Buying smaller bottles and finishing them, and choosing water-based or lower-solvent formulations where they work, removes most of the problem.
- Water-based and peel-off polishes
- Smaller bottles you will actually finish
- Passing usable polish to a salon, school, or theatre group
Not Accepted
- Bottles of polish or remover in curbside recycling or trash
- Remover poured down a sink, toilet, or storm drain
- Full bottles left in a hot car or near a heat source
- Acetone, a Class IB flammable liquid with a flash point near 0 degrees Fahrenheit
- Other solvents used in non-acetone removers
- Nitrocellulose and plasticizers in polish
- Solvent vapors, which are heavier than air and collect in enclosed spaces
