Why make the swap

  • Why switch to TPHP-free nail polish

    Polishes labelled free of TPHP leave that plasticizer out, along with formaldehyde, toluene and DBP. You keep the colour and shine without the chemical the Duke study tracked.

  • What's the concern with conventional nail polish

    Duke researchers found the plasticizer triphenyl phosphate (TPHP) in 8 of 10 nail polishes, including two that didn’t list it. It’s absorbed mainly through the skin, and what that means for health isn’t settled.

  • General information, not medical advice. Ask your doctor, especially if you’re pregnant, nursing or have a health condition.

  • Good to know before you buy

    Look for ‘TPHP’ or ‘triphenyl phosphate’ on the free-from list; basic ‘5-free’ labels usually don’t cover it. Every polish, these included, dries to a thin polymer film. There’s no polymer-free polish yet.

Questions people ask

What is TPHP in nail polish?

TPHP is triphenyl phosphate, a plasticizer. Duke researchers found it in 8 of 10 polishes, and a urine marker rose about 7-fold after painting.

Does ‘5-free’ nail polish mean TPHP-free?

Usually not: ‘5-free’ doesn’t mean TPHP-free. Look for ‘TPHP’ or ‘triphenyl phosphate’ on the free-from list.
