EU Bans TPO in Gel Nail Polishes: Implications and Reactions

Overview of the Ban
On September 1, 2025, the European Union implemented a ban on trimethylbenzoyl diphenylphosphine oxide (TPO), a chemical widely used in gel nail polishes. TPO serves as a photoinitiator, allowing the gel to harden quickly under ultraviolet (UV) or LED light, contributing to the long-lasting and glossy finish that many consumers favor. The ban was enacted due to animal studies linking TPO to potential reproductive toxicity, classifying it as a category 1B carcinogen, mutagen, or reproductive toxicant (CMR) under EU regulations.
Health Concerns and Regulatory Responses
The decision to ban TPO stems from studies indicating adverse reproductive effects in animals, including infertility in female rats and reduced reproductive health in males. Experts, including Dr. Sharrón L. Manuel, a reproductive endocrinologist, support the precautionary approach taken by the EU, emphasizing the need for further research on the safety of TPO in humans. While there are currently no large-scale human studies confirming these risks, the EU's regulatory framework prioritizes potential hazards over established risks.
In contrast, the U.S. Food and Drug Administration (FDA) has not imposed similar restrictions, allowing TPO-containing products to remain on the market. The FDA requires manufacturers to demonstrate safety but does not mandate pre-market approval for cosmetics, leading to concerns about the regulatory disparity between the EU and the U.S.
Industry Reactions and Future Implications
The ban has prompted significant reactions within the beauty industry. Francesca Rapolla, scientific affairs manager at the Cosmetic, Toiletry & Perfumery Association, noted that the industry could not defend the continued use of TPO due to the availability of alternative ingredients. Some brands, such as The GelBottle, have already begun transitioning to TPO-free formulations in anticipation of the regulatory changes.
However, dissenting voices exist. Doug Schoon, a scientific consultant, argues that the ban lacks a scientifically justified risk assessment and could lead to unnecessary waste of safe products. A Belgian wholesaler has even launched a protest website, claiming the ban could severely impact small businesses.
Consumer Guidance and Alternatives
For consumers in the EU, the immediate impact of the ban means that salons must dispose of existing TPO-containing products and cannot sell or use them. In the U.K. and the U.S., where TPO remains legal, consumers are encouraged to inquire about the ingredients in their gel polishes. Brands are expected to phase out TPO in preparation for potential future bans, with many already offering TPO-free options.
Experts advise consumers concerned about TPO to consider alternatives such as traditional nail polish, which does not require UV light, or TPO-free gel options. The American Academy of Dermatology also recommends applying sunscreen to hands before UV exposure during gel manicures to mitigate skin cancer risks associated with UV light.
Conclusion
The EU's ban on TPO in gel nail polishes reflects a growing trend towards stricter cosmetic regulations based on precautionary principles. While the U.S. continues to allow TPO, the potential for future regulatory changes looms, prompting brands and consumers alike to adapt to a landscape increasingly focused on safety and health. As the beauty industry evolves, consumers are encouraged to stay informed about the products they use and prioritize their health.
