Updated February 2026

TPO was banned in cosmetic products in the EU starting 1st September 2025.

The TPO ban is scheduled to come into effect in the UK on 15th August 2026, after which any products that contain TPO cannot be sold. The use of TPO-containing products will be prohibited from 15th February 2027. 

We understand many of you have questions and concerns about these changes and how they might impact our products. This blog aims to address any frequently asked questions. 

What is TPO?

TPO, or Trimethylbenzoyl Diphenylphosphine Oxide (also known as diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide), is a photo initiator used in nail products to help harden and cure the coatings quickly under UV light.

Why is it being banned?

Regulatory bodies in the UK are implementing the ban as part of broader cosmetic safety regulations aimed at reducing the use of chemicals that may pose risks, particularly in products that come into direct contact with the skin.

What is Glossify's approach to the changes?

As a company, we constantly assess cosmetic regulations and have been updating our product formulations in-line with guidelines and upcoming changes.

TPO has been widely used in nail products for years, and all of our current formulations are safe for use on your clients.

Exciting changes are happening at Glossify and all will be revealed in due course.

We are actively working to offer an alternative formulation to any TPO containing products ahead of the regulatory deadlines in the UK, to ensure a smooth transition. Once the new rules take effect, none of our products sold from August 2026 will contain TPO.

Currently, any TPO containing products are now unavailable to purchase in the EU from our website, to comply with the European ban.

What Glossify product contain TPO?

Any products that contain TPO will have diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide listed under the ingredients on their Safety Data Sheets. You can access our SDS here.

Can I still use Glossify products after the ban?

You can use Glossify products that contain TPO until 15th Feb 2027.
