The recent 'gel nail ban' in the UK has sparked concern among manicure enthusiasts, but it's not as drastic as it seems. The ban primarily targets a specific chemical, trimethylbenzoyl diphenylphosphine oxide (TPO), used in some gel polishes. This chemical, a photoinitiator, initiates a chemical reaction when exposed to UV light, giving gel manicures their glossy, durable finish. The ban, effective in England, Wales, and Scotland, aligns with the European Union's regulations, which have been in place since September 1, 2022. The focus on TPO is due to its potential hazardous properties, as studies linked high consumption to fertility and reproductive issues in animals. However, the amount used in nail products is significantly lower than the threshold causing negative effects, and the potential for absorption into the body is minimal. The ban is a precautionary measure, ensuring the safety of cosmetic ingredients. The Cosmetic, Toiletry and Perfumery Association (CTPA) and the National Hair & Beauty Federation (NHBF) have collaborated to provide guidance on TPO, emphasizing its strict safety criteria under the CLP chemicals law. Despite the ban, TPO-free gels are already available, and traditional air-dried polishes do not require TPO. Nail technicians can continue using existing TPO stock until supplies deplete, but new purchases are prohibited. The regulation of this ban is unclear, but citizens can report suspected illegal cosmetic products via the Citizens' Advice Consumer Helpline. To check for TPO in gel products, consumers can look for the full chemical name on the packaging, as TPO is unlikely to be listed by its shortened name. This development highlights the industry's commitment to safety and the evolution of cosmetic ingredients, ensuring that nail care remains a safe and enjoyable experience for consumers.
