The European Union has banned the use of a chemical called Trimethylbenzoyl Diphenylphosphine Oxide (TPO) in gel nail polish starting September 1, 2025. This ingredient, used to give gel polish its glossy finish and quick drying properties, has been linked in animal studies to fertility issues, reproductive toxicity, and possible carcinogenic effects.
The ban requires nail salons across the EU to dispose of TPO-containing products immediately. Experts caution that while human evidence is limited, the precautionary approach prioritises women’s health. The banned ingredient remains in use in the U.S., prompting calls for closer regulation.
EU’s Precautionary Ban on Toxic Gel Nail Polish Ingredient
TPO serves as a photoinitiator that helps gel nail polish harden under UV or LED lights, giving it the durable, glossy finish consumers prefer. However, the European Commission classified TPO as “carcinogenic, mutagenic, or toxic for reproduction” following animal studies showing severe fertility disruptions in exposed rats – including testicular atrophy in males and irregular cycles in females.
The EU, under a regulation known as Omnibus VII, now prohibits the sale, import, and use of cosmetics containing TPO. Nail salons must safely discard existing stock with no grace period, impacting thousands of businesses. The decision underscores the EU’s cautious approach to potential endocrine disruptors, chemicals that interfere with hormonal function.
Health Concerns Beyond Beauty
Experts warn that repeated exposure to TPO can lead to skin allergies, dermatitis, and potential reproductive harm, though direct human studies remain scarce. Dermatologist Dr. Chandani Jain Gupta explains, “TPO can cause skin irritation and sensitivity, especially among salon workers and frequent users. Prolonged exposure may affect reproductive health, warranting this ban.”
Toxicologists note that while rats were exposed to much higher doses orally than humans receive topically via manicures, the EU opted for precaution. Dr. Hannah Kopelman, dermatologist, says, “The ban reflects prioritising health over convenience despite the absence of conclusive human evidence.” Consumers are advised to opt for TPO-free gel alternatives to reduce risk.
Industry and Consumer Response
The ban has caused concern among European nail salons and retailers due to economic impacts and supply challenges in transitioning to TPO-free products. Some industry representatives argue there is insufficient human data to justify a complete ban, worrying about small businesses and product availability. Meanwhile, consumer safety advocates praise the ban as a forward-thinking move ensuring long-term wellbeing.
In the United States, the ingredient remains legal and is used in many gel polishes, exposing American consumers to the potential risk faced earlier by Europeans. Calls are growing for the U.S. FDA to reevaluate its regulatory stance on TPO and similar chemicals.
The Logical Indian’s Perspective
Beauty and wellbeing should never be mutually exclusive. The EU’s cautious stance highlights the importance of public health taking precedence over cosmetic convenience and market interests. The Logical Indian supports such preventive measures and urges consumers globally to stay informed and favour safer alternatives.
The debate also calls for a global consensus on cosmetic safety standards rather than patchwork regulations.
