Nail Ingredient Checker

Paste any nail product ingredient list and instantly see flagged monomers, allergens, and restricted ingredients.

Paste the INCI list from any gel, acrylic, or polish product and get an instant read on what's inside. The checker flags three things. Restricted: ingredients banned or legally limited in major markets, including MMA, TPO (banned in the EU since September 2025), and the old "toxic trio" of toluene, DBP, and formaldehyde. Sensitizers: the documented allergy triggers behind most gel reactions, like HEMA, Di-HEMA TMHDC, HPMA, and IBOA. Watch: permitted ingredients worth knowing about, such as TPO-L, the common TPO replacement currently under EU review. Each flag comes with a plain-English explanation and a note on where it's restricted. Your pasted label is re-typeset as color-coded chips, so you can see exactly which ingredient triggered which flag. Everything runs inside your browser. No account, no data collection, no network requests. The reference database ships with the extension and works offline.
