About 2.4 billion bottles of nail polish are sold around the world each year, with more than 600 million bought in the U.S. alone. Most Americans who use nail polish have eight to twelve bottles at home. When a color is no longer wanted, almost none of these bottles can go in the recycling or regular trash.

Nail polish contains solvents, plasticizers, and resins that are considered household hazardous waste (HHW), just like oil-based paints and pesticides. State and local rules, based on federal law, decide how it should be handled. The good news is that by 2026, more brand take-back programs and beauty recyclers are giving people better options than waiting for a rare HHW collection day.

Why That Little Bottle Counts as Hazardous Waste

A regular bottle of nail polish is about 70% solvents, usually ethyl acetate, butyl acetate, and sometimes toluene, mixed with film-formers, plasticizers, and pigments. These solvents are flammable, and some plasticizers are linked to reproductive harm. Dried polish acts like a thin layer of car paint. The U.S. EPA says household hazardous waste includes products that are ignitable, corrosive, reactive, or toxic. Nail polish burns easily and is toxic, so many local programs, from Sonoma County to the City of London, list it as hazardous waste.

Three ingredients in nail polish have raised the most concern and are called the toxic trio: toluene, which can harm development and the nervous system; formaldehyde, which is a known cancer risk; and dibutyl phthalate (DBP), which can affect reproduction. The European Union banned DBP in cosmetics in 2004. The U.S. does not have a similar federal ban, but most big brands have changed their formulas. In 2023, California took an extra step by regulating toluene in nail products.

Changing the formula does not always remove all harmful chemicals. A 2026 study in Science of the Total Environment, using tests from the California Department of Toxic Substances Control, looked at 178 nail products of different types. The researchers found 29 different chemicals, including toluene, formaldehyde, and methyl methacrylate. In 92% of the products, chemicals were found that were not listed on the label. Products for children had the same chemical levels as those for adults.

A separate study by California’s Department of Toxic Substances Control in 2012 found that 10 out of 12 products labeled as “toluene-free” still contained toluene, with levels ranging from 42 ppm to 177,000 ppm. Five out of seven products claiming to be free of the toxic trio actually contained at least one of those chemicals. Labels like “3-free,” “5-free,” and “10-free” are now common. These labels are not regulated by the federal government and often do not match what is found in lab tests.

Gel polish has its own set of chemical issues. In September 2025, the EU banned trimethylbenzoyl diphenylphosphine oxide (TPO), which helps gel polish harden under UV light, because it was classified as a category 1B reproductive toxicant. This ban stops both the sale and professional use of gels with TPO in all 27 EU countries. However, TPO is still legal in the U.S.

What Not to Do With Old Polish

Never pour leftover polish or remover down the sink, tub, or storm drain. The solvents can harm septic systems, damage wastewater treatment plants, and end up in rivers or lakes. Do not put liquid polish in your regular trash or recycling, since it can leak and harm sanitation workers or contaminate other materials. Also, do not try to burn polish to dry it out faster, because the solvents catch fire easily and the fumes are toxic.

Programs Worth Knowing About

Some brands and salon companies now have special take-back programs for nail polish. Most of these programs accept bottles from any brand, not just their own. While they do not cover every U.S. zip code and often require shipping, they are a better option than throwing polish in the landfill.

Côte Beauty Recycling Program. The Los Angeles-based clean-beauty brand partners with PACT Collective, a nonprofit focused on hard-to-recycle beauty packaging, to accept nail polish bottles from any brand by mail. Côte instructs consumers not to rinse the bottles because the polish is upcycled into industrial paint. Ship bottles to Côte Beauty Recycling Program, 11601 Wilshire Blvd, Suite 1750, Los Angeles, CA 90025. The brand offers loyalty discounts on future purchases for participants.

Zoya Earth Month Exchange. Zoya, a New Jersey-based 10-free nail polish brand, runs an annual nail polish exchange each year around Earth Day. Recycling customers can order Zoya shades at a discount and mail in their unwanted polishes from any brand. Zoya disposes of the returned bottles through a commercial hazardous-waste handler and, in some years, donates usable polishes to local causes. Outside the promotion window, the exchange is not active, so timing matters.

Tenoverten. The clean-beauty nail salon Tenoverten partners with Chemwise, a chemical recycling and disposal company, to take old polish bottles of any brand at its salon locations. Chemwise stores the collected polish in temperature-controlled facilities and aggregates it into batches that are reformulated as paint for industrial equipment. Bottles, caps, and brushes are recovered separately.

PACT Collective beauty drop-offs. PACT Collective, founded in 2021 by Credo Beauty and MOB Beauty, now operates more than 3,300 drop-off bins at retailers including Ulta Beauty (about 1,350 U.S. stores), Credo Beauty, Sephora, and partner brand locations. Important caveat: PACT bins accept hard-to-recycle beauty packaging — pumps, tubes, caps, lipstick bullets — but explicitly exclude liquid nail polish and polish remover because they are hazardous. Empty, rinsed polish bottles may or may not be accepted depending on local rules. For full bottles, route through Côte’s mail-in program (which uses PACT infrastructure on the back end) or a municipal HHW facility.

Beauty packaging is one of the hardest types of waste to recycle. PACT says that over 120 billion beauty packages are made worldwide each year, but only about 9% get recycled. Most are too small, made of mixed materials, or too dirty for regular recycling. Liquid nail polish is especially tough to recycle, which is why special brand programs are important.

The Local HHW Route Still Works

If a mail-in program isn’t a fit, every U.S. county has some form of household hazardous waste handling — though access varies dramatically. Some counties operate year-round permanent facilities; others run one-day collection events two or three times a year; rural areas may require appointments or shared regional sites. Earth911’s recycling search directory is the most comprehensive U.S. database, listing more than 100,000 collection points across 350+ material categories. Enter a ZIP code and “nail polish” to find the nearest option.

Before driving over, call ahead. HHW facilities almost always restrict drop-offs to residents of the county or city that funds them, and they often limit the quantity accepted per visit. Some charge a small fee; many do not. Bring polish in its original bottle, sealed tight, and place bottles inside a sturdy box or bag in case of leaks. While there, it’s a sensible trip to combine: leftover paint, motor oil, garden chemicals, expired medications, and old batteries are typically accepted on the same visit.

Reducing the Waste Upstream

Throwing away polish should be the last resort. A better solution is to buy less polish and pick formulas with fewer hazardous ingredients from the start. Earth911 has a guide to safer nail polish alternatives, including water-based and lower-chemical brands. There are a few trends to keep in mind.

Mini-bottle subscriptions and seasonal color trends encourage people to buy and throw away polish more often. In the U.S., about 600 million bottles are sold each year, even though most polish users already have eight to twelve bottles at home. This demand adds up and increases waste.

Water-based polishes have much fewer solvents and are easier to take off without acetone, but they do not last as long and cannot fully replace gel polish. “10-free” or higher polishes are better than regular ones, but DTSC studies warn that the label does not tell the whole story. Ingredients can vary by brand, and unwanted chemicals may still be present even after reformulation.

Nail polish remover should be handled with the same care as nail polish. Most removers with acetone are flammable and are also considered hazardous waste. Let cotton balls and pads soaked with remover dry out completely in a well-ventilated area before throwing them away. Any leftover remover should be taken to the HHW facility with your old polish.

What You Can Do

• See if a brand-run program works for you. Côte Beauty takes bottles from any brand by mail all year. Zoya has an Earth Month exchange in April. Tenoverten salons accept walk-in drop-offs at their locations.
• Find the closest HHW collection site. Use Earth911’s recycling search to look up a household hazardous waste facility or event. Call first to check residency rules and how much you can bring.
• Try to buy less polish in the first place. If you already have ten bottles, adding a new color is more likely to become waste than a useful addition. Finish what you have before opening new bottles.
• Be skeptical when reading labels. Terms like “non-toxic,” “clean,” and “X-free” are not defined by the federal government. The Environmental Working Group’s Skin Deep database gives hazard scores for individual products and offers more detailed comparisons than marketing claims.
• Do not pour polish or remover down the drain. The solvents can harm wastewater treatment systems, damage septic fields, and end up in rivers or lakes.
