By San José, Costa Rica — Starting September 1, 2025, the European Commission has banned the use of two chemicals, triphenyl phosphate (TPO) and dimethyl-p-toluidine (DMTA), in nail polishes and semi-permanent gels. These chemicals, classified as CMR (carcinogenic, mutagenic, or toxic for reproduction), pose significant health risks to both nail salon professionals and consumers.
The ban, enacted through Regulation (EU) 2025/877, applies across all European Union member states. The Commission also advises consumers to discontinue using products containing these substances.
To understand the legal implications surrounding the chemicals used in nail polish, TicosLand.com spoke with Lic. Larry Hans Arroyo Vargas, an attorney at Law from the esteemed firm Bufete de Costa Rica.
The regulatory landscape for cosmetic products, including nail polish, in Costa Rica is primarily governed by the Ministry of Health. While specific chemical compounds may be restricted or prohibited outright, the onus is largely on manufacturers and importers to ensure compliance with these regulations. Consumers who experience adverse reactions potentially linked to nail polish chemicals should retain the product and packaging, seek medical attention, and consult with legal counsel to explore potential remedies.

Proactive steps like retaining product information and seeking medical advice can empower individuals to protect their well-being and pursue appropriate recourse. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for sharing his valuable legal expertise with TicosLand.com readers.
Nail salon professionals face the highest risk due to daily exposure to these chemicals. TPO, used as a photoinitiator in UV curing, can irritate skin, trigger allergies, and damage DNA. DMTA, an adhesive activator that hardens polish, is toxic by inhalation and skin contact, with potential harm to the liver and kidneys.
Toxicologists warn that prolonged exposure to TPO and DMTA significantly increases the risk of cancer and reproductive issues. The ban is part of a broader initiative by the European Chemicals Agency (ECHA) to restrict hazardous chemicals in cosmetics and other everyday products. Further restrictions on substances like triclosan and certain nanomaterials are forthcoming.
Pregnant women and frequent users of cosmetic products are particularly advised to exercise caution. Consumers are encouraged to carefully review product ingredients and avoid those containing potentially toxic compounds.
This ban reflects the growing awareness of the potential health risks posed by chemicals in everyday products. The EU’s proactive approach sets a precedent for other regions to follow, prioritizing consumer safety and promoting greater transparency in the beauty industry.
The ECHA’s ongoing efforts to identify and restrict hazardous substances underscore the importance of continued research and regulation in protecting public health. Consumers should remain informed and advocate for safer products, encouraging manufacturers to adopt cleaner, more sustainable alternatives.
This move signifies a positive step towards reducing exposure to harmful chemicals and promoting healthier beauty practices. The future impact of this regulation will be closely monitored as other countries consider similar measures to safeguard public health.
