What is TPO and where is it used?
TPO is a photoinitiator commonly used in artificial nail products, especially gels, to initiate polymerization through UV light. Despite its effectiveness, this ingredient has raised toxicological concerns.
Why was it banned?
This decision is aligned with Regulation (EC) No 1223/2009, which prohibits substances classified as CMR (carcinogenic, mutagenic, or toxic to reproduction) in categories 1A, 1B, or 2. Commission Regulation (EU) 2025/877, published on May 12, amended Annex II of the European regulation by adding TPO to the list of prohibited substances (entry No. 1731).
Deadlines and responsibilities
As of September 1, 2025, it will be prohibited to place on the market or distribute any cosmetic products containing TPO. INFARMED states that:
- Distributors and commercial entities must take all necessary measures to ensure these products are not placed on the market, made available, or delivered to the end user after that date.
- The ban that comes into effect on September 1, 2025, means that cosmetic products containing Trimethylbenzoyl Diphenylphosphine Oxide (TPO) should no longer be used from that date onwards.
If you are a manufacturer, distributor, or brand owner of cosmetic products:
- Check the formulas of your products.
- Replace TPO with safe and authorized alternatives.
- Update your Product Information File (PIF), labelling, and ensure full legal compliance by September 1, 2025.
- Inform your customers and partners about this regulatory change.
