From September 1, 2025, a new regulation came into effect in the European Union banning the use of the substance TPO (Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide) in nail products. This ban applies to all gels, bases, and tops and is essential for everyone working in the nail industry.
What is TPO?
TPO = Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
👉 It is a photoinitiator, a substance that enables gels and gel polishes to harden under a UV/LED lamp.
The problem is that TPO has been classified as a hazardous substance with harmful health effects.
Why is TPO banned?
The European Union has classified TPO as a substance that can be toxic.
From September 1, 2025, the sale and use of products containing TPO is prohibited throughout the EU.
Risks associated with TPO:
-
skin irritation and sensitization,
-
higher risk of allergies,
-
potential long-term negative effects.
How can I tell if a product contains TPO?
Check the ingredient list (INCI) on the packaging. If you see:
Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
or the abbreviation TPO
➡️ the product is no longer legal and must not be used in the EU.
