Srilanka, Sept. 8 -- The European Union is now prohibiting the use of a key chemical ingredient in some gel nail polishes and other cosmetic products.

The ban, which went into effect this week, targets the use of trimethylbenzoyl diphenylphosphine oxide or TPO, which was classified as a type of "reproductive toxicant" by European regulators, according to the European Commission.

TPO works as a photoinitiator, meaning it responds to light. In gel nail polish, it helps the polish set under ultraviolet or UV light.
