TPO vs TPO-Free: Understanding the 2025 EU Regulations for Nail Products

🔬 TPO on Labels: The Complete Guide to the EU 2025 Nail Product Regulations

——Is your gel polish actually safe?

⚠️ A Note From Us

As a European professional nail brand, we get asked the same question every single day: "Does my product contain TPO?"

It's a fair question. And starting September 2025, it matters more than ever. The EU is banning TPO in nail products — but here's the thing: we're going to break it all down in plain English. No jargon. No confusion. Just the facts, the way you'd want them explained.

🔍 What Even Is TPO?

TPO (Trimethylbenzoyl Diphenylphosphine Oxide) is a photoinitiator commonly used in UV/LED gel polishes to help them cure under UV lamps.

So why is the EU banning it?

▪ The EU placed it on the precautionary ban list
▪ Animal studies showed potential risks with long-term, high-dose exposure
▪ Under normal human use, there's currently no evidence of harm

📌 The Arte Clavo Take: The ban is precautionary. Risk under normal use is very low — but why settle for "probably fine" when there are cleaner alternatives available? We made the switch. You can too.

📅 The Ban Timeline

Date	What's Happening
September 1, 2025	EU officially bans TPO in nail products
Immediate	Sale and use of TPO products prohibited
Right Now	Clear your existing stock — time is running out

🔍 How to Spot TPO on Any Label

TPO can hide under different names on ingredient lists. Here's what to look for:

⚠️ If You See Any of These Names, Put It Down:

Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide
(2,4,6-Trimethylbenzoyl) diphenylphosphine oxide
2,4,6-Trimethyl benzoyldiphenyl phosphine oxide

💡 Where to Look

✅ Check these: UV/LED gel polishes, base coats, top coats
❌ Don't worry about these: Regular nail polish, acrylic systems

💡 Pro tip: Flip the bottle over, find the INCI ingredient list, and do a quick search. If any of those names show up — it's time to replace that product.

✅ The Better Alternatives (That We've Already Switched To)

Good news: there's a better lineup. Arte Clavo made the switch back in late 2024. Here's what's currently recommended:

🌟 Recommended TPO-Free Photoinitiators

Alternative	Chemical Name	CAS Number	Why It Works
TPO-L	Ethyl Trimethylbenzoyl Phenylphosphinate	84434-11-7	Strong curing, widely used
TMO (TPO-R) ⭐	Trimethylbenzoyl Ditolylphosphine Oxide	270586-78-2	Arte Clavo's choice: Great color stability
BAPO	Bis-Trimethylbenzoyl Phenylphosphine Oxide	162881-26-7
HCPK	Hydroxycyclohexyl Phenyl Ketone	947-19-3	Full EU compliance

🌟 Why We Chose TMO

Because it simply doesn't have a weak point:

✅ Superior curing performance — cleaner, more even set
✅ Excellent color stability — no yellowing, no fading
✅ 100% EU compliant
✅ Higher safety profile — because that matters
✅ Our in-house lab testing agreed
