As part of our ongoing commitment to product safety and compliance with evolving cosmetic regulations, we are sharing important updates regarding the forthcoming ban of the ingredient Trimethylbenzoyl Diphenylphosphine Oxide (TPO) in nail products across the European Union.

TPO is a photo-initiator commonly used in UV/LED-curable nail products to initiate the curing process. Effective 1 September 2025, the European Commission will prohibit the use of TPO in cosmetic products sold within the EU. Similar restrictions are expected to take effect in Great Britain by late 2026.

It is important to note that the upcoming ban is a precautionary measure, not the result of any widespread safety issues in the nail industry. When used correctly by trained professionals, TPO-containing products have demonstrated a strong safety profile. However, under Article 15 of the EU Cosmetics Regulation, CMR substances are not permitted in cosmetics unless stringent exemption criteria are met. In the case of TPO, the industry was unable to secure such exemptions, primarily due to the availability of alternative photo-initiators.

What This Means For You & Your Clients

• New formulations are already in place. We have proactively reformulated affected products using a new and fully compliant photoinitiator. This alternative delivers the same high-performance results and ensures full compliance with the updated regulations. This reformulation has been in place across our affected products since 2024.
• There is no need to panic. Products containing TPO currently in use remain safe when applied correctly. 
• No immediate disposal required. If you currently own or use a product containing TPO, you may continue to use it safely. The industry is currently seeking advice on the continued use of products already in circulation after September 1st; however, there has been no updated guidance to date. We will issue any updated advice as soon as it becomes available.

We understand that regulatory changes can raise questions, and we are here to support professionals through this transition. If you have any questions or concerns relating to this change, please do reach out to our team, who will be happy to advise you further.
