Goodbye TPO in nail products: what's changing from September 1, 2025?
A new European regulation will come into force on 1 September 2025, banning the use of TPO (trimethylbenzoyl-diphenylphosphine oxide) in cosmetic products.
TPO is a photoinitiator commonly used in gels and semi-permanent nail polishes that cure under UV light. This substance, although effective in curing, was subject to regulatory review due to potential health risks, leading to its ban.
What does this mean for nail professionals?
Many brands will have to quickly change their formulations to remain compliant with the law. During this transition period, there will be confusion in the market, with companies forced to dispose of old stock and reformulate their products.

For Diro Nails this regulation does not represent a problem .
