Why is a chemical in gel manicures banned in UK and EU, but allowed in India?
- TPO, or trimethylbenzoyl diphenylphosphine oxide, is a chemical that helps gel nail polish harden under UV or LED lamps.
- The UK banned TPO in cosmetic products from August 15, 2026, following an EU ban over concerns about its potential reproductive toxicity.
- Animal studies found testicular damage in male rats exposed to high doses of TPO, while genetic-damage tests found no meaningful risk.
- India has no similar restriction on TPO, and the chemical continues to be used in UV and LED gel nail products sold in the country.
