As we step into September, a new regulation in the European Union is set to impact the nail care industry. From September 1, 2025, the EU has banned the use of TPO (trimethylbenzoyl diphenylphosphine oxide) in nail polishes, citing health concerns. This move has significant implications for both nail technicians and consumers. Here’s a detailed look at what this ban entails and how it might affect your regular gel manicure.
Understanding TPO
TPO is a key ingredient in many gel nail products, particularly top coats. It acts as a photoinitiator, reacting to UV or LED light to transform soft gel into a hard, glossy finish. Unlike regular air-dry nail polishes, gel products rely on TPO for their durability and low yellowing rate. However, concerns about its potential health risks have led to its classification as a CMR (carcinogen, mutagen, and reprotoxic) substance by the EU.
Health Concerns
Research on rats has shown that ingesting TPO can lead to reproductive difficulties and negative effects on the endocrine system. While these studies focused on ingestion, the EU has decided to err on the side of caution by banning TPO in nail products. The UK is also expected to follow suit, with a ban likely to be implemented by late 2026 or early 2027.
Is TPO Dangerous for Humans?
It’s important to note that the studies linking TPO to health issues involved ingestion, which is not how it is typically used in nail products. However, given the potential risks, many brands have already reformulated their products to be TPO-free. For those with concerns about fertility or endocrine issues, choosing TPO-free products is advisable.
Industry Response
Reputable brands have been aware of the impending ban for some time and have spent considerable effort reformulating their products. As a result, consumers should not notice a significant difference in the performance of their favorite gel polishes. However, some brands may face temporary stock issues as they transition to TPO-free formulations.
The Role of TPO-L
A modified version of TPO, known as TPO-L, has been developed as a legal alternative. TPO-L replaces a benzene ring in the TPO structure with an ethoxy group, making it safe for use in both the UK and the EU. Consumers can continue to enjoy gel manicures with the assurance that TPO-L is a safe and effective substitute.
Consumer Advice
For now, consumers should be aware that gel brands are working closely with chemists to ensure their products remain safe and effective. While there may be some temporary disruptions, the industry is committed to providing high-quality, TPO-free options.
The TPO ban marks a significant shift in the nail care industry, driven by a commitment to consumer safety. While the transition to TPO-free products may bring some challenges, the industry’s proactive approach ensures that consumers can continue to enjoy their favorite gel manicures without compromising on quality or safety. As we navigate this change, it’s essential to stay informed and support brands that prioritize health and innovation.
