Nail Tech Education: Understanding the EU Ban on TPO (Trimethylbenzoyl Diphenylphosphine Oxide)
Some nail techs feel worried when they hear about the EU ban on TPO – a common photo-initiator used in gel polishes. If chemistry isn’t your strong point, don’t stress! Let me simply break it down for you🌸💅
What is TPO?
TPO (Trimethylbenzoyl Diphenylphosphine Oxide) is a photo-initiator. That means its job is to start the curing reaction in your gel polish when exposed to the correct UV/LED light.
Why the Ban?
The EU has decided to restrict TPO due to concerns over safety data. This doesn’t mean your gels are unsafe—it just means manufacturers must use alternative photo-initiators moving forward.
Here’s the Good News
You don’t need to worry about your gel polishes being left without a way to cure. When TPO is phased out, manufacturers will use other safe and effective photo-initiators such as:
° TPO-L ((2,4,6-trimethylbenzoyl) phenylphosphinate)
° Acyl phosphine oxides
° Ethyl (various ethyl-based initiators)
° Hydroxycyclohexyl phenyl ketone
° Bis(4-methylphenyl)phosphinyl oxide
These alternatives still ensure your gel polishes cure properly under your lamp, giving you the same strong, long-lasting results you’re used to.
Takeaway for Nail Techs
° Don’t panic when you hear about “TPO bans.”
° Your gels will still cure and perform well.
Manufacturers are already reformulating with other photo-initiators to keep your products compliant and effective.
So breathe easy—your sets are safe, beautiful, and future-proof! 💅
