Your nail polish might be the most overlooked toxin in your beauty routine. Here's what's actually in conventional polish — and the cleanest alternatives we trust.
What's Actually in Conventional Nail Polish?
Most conventional nail polishes contain a cocktail of chemicals that have raised serious health concerns. The most notorious are the "Toxic Trio" — formaldehyde, toluene, and dibutyl phthalate (DBP) — but the list goes much further than that.
A landmark study published in Environment International (2021) tested 24 nail polish products and found that TPHP (triphenyl phosphate), a plasticizer and suspected endocrine disruptor, was detectable in the urine of participants within hours of applying nail polish — even when gloves were worn. The researchers concluded that nail polish is a significant source of TPHP exposure, particularly for salon workers and frequent users.
Here's a quick breakdown of the chemicals most commonly found in conventional nail polish and why they matter:
- Formaldehyde — a known human carcinogen used as a nail hardener. Linked to respiratory issues and skin sensitization.
- Toluene — a solvent that keeps polish smooth. Associated with neurological effects and developmental toxicity.
- Dibutyl Phthalate (DBP) — a plasticizer linked to hormonal disruption and reproductive toxicity.
- Camphor — can cause nausea, dizziness, and seizures in high doses; a known skin irritant.
- TPHP (Triphenyl Phosphate) — a suspected endocrine disruptor that absorbs through the nail into the bloodstream.
- Formaldehyde Resin — a derivative of formaldehyde that can cause allergic reactions.
- Xylene — a solvent linked to headaches, dizziness, and liver damage with prolonged exposure.
