A significant change is on the horizon for nail salons across the UK as a crucial ingredient in gel nail products has been prohibited. The ban on Trimethylbenzoyl diphenylphosphine oxide (TPO), a chemical that enhances the durability of gel manicures, is now in effect. While this may cause concern for manicure enthusiasts, it’s essential to understand what this regulation entails and how it will affect nail treatments moving forward.
Understanding the Ban
The recent legislation targeting TPO has been implemented in England, Wales, and Scotland, aligning with similar measures already enforced in the European Union since September 1, 2025. TPO is classified as a “photoinitiator,” a substance that enables gel nail polish to harden quickly under ultraviolet (UV) light. This ingredient plays a pivotal role in prolonging the wear and vibrancy of gel manicures.
Although salons may see a shift in their product offerings, this ban does not signify the end of gel manicures. Salons can continue to provide services using TPO until their existing stock is depleted, with a deadline set for February 14, 2027, to cease all usage of the ingredient.
Timeline of Changes
The UK implementation of the ban officially began on Saturday, meaning manufacturers can no longer supply new products containing TPO to salons. However, the phased approach allows salons to continue using any remaining stock until it runs out, ensuring customers can still enjoy their favourite gel treatments in the interim.
It is important to note that gel nail products containing TPO will still be available in regions such as the United States, Australia, and parts of Asia, allowing for continued global access to these treatments.
Reasons for the Ban
Concerns surrounding TPO stem from animal studies that have suggested potential links to long-term fertility issues. Caroline Rainsford, the Director of Science at The Cosmetic, Toiletry and Perfumery Association (CTPA), highlighted the rationale behind the ban. She explained, “The reason why TPO has been banned in cosmetic products in the EU is based on its hazardous properties, meaning how a substance might behave under a ‘worst case’ situation when our bodies are exposed to a very large amount. This is not how TPO is used in cosmetics. The amount of this ingredient used in nail products is over a thousand times less than the amount which could have any negative effect on fertility, and these products are applied to the nail, so the potential for the ingredient to be absorbed into our bodies is even smaller.”
Alternatives for Salons
With TPO’s removal from the ingredient list, nail salons will need to adapt by sourcing alternative products for gel manicures. Fortunately, TPO-free gel options are already available, and many salons have been using these safer formulations for some time. While some alternatives may share a similar chemical structure, it is crucial to evaluate each product’s safety profile to ensure compliance with health and safety standards.
Why it Matters
The ban on TPO marks a significant step in prioritising consumer safety within the beauty industry. As awareness of the potential risks associated with certain chemicals grows, regulations like this not only protect public health but also encourage manufacturers to innovate and provide safer alternatives. This shift could ultimately lead to a broader commitment to health-conscious practices across the cosmetics sector, ensuring that beauty treatments enhance well-being without compromising safety. As consumers, staying informed about the products we use is essential for making choices that align with our health and values.
