UK Bans TPO in Gel Nail Products: Implications for Kenya’s Beauty Industry

The United Kingdom has implemented a ban on Trimethylbenzoyl Diphenylphosphine Oxide (TPO), a chemical commonly used in gel nail products, starting August 15, 2026. This move follows the European Union's earlier prohibition effective from September 1, 2025.

TPO acts as a photoinitiator that triggers the curing process of gel polishes when exposed to UV or LED light, enabling the gel to harden into a durable, glossy finish. Its popularity stems from the advantages gel manicures offer over traditional nail polish, including longer-lasting wear and faster curing times.

Why the Ban?

Regulators have raised concerns after TPO was classified as a Category 1B reproductive toxicant under European hazard classifications, indicating it is presumed toxic to reproduction based on animal studies. The ban aims to reduce potential health risks, although industry experts emphasize that the decision is precautionary and does not confirm harm from typical product use.

Impact on Kenya

Kenya does not currently have a specific ban on TPO in cosmetics. The Kenya Bureau of Standards regulates cosmetic products and tests them, but products containing TPO remain legal unless otherwise restricted. This regulatory gap means Kenyan salons and distributors importing gel nail products must be vigilant about ingredient compliance, especially when sourcing from markets where TPO is prohibited.

Some gel products in Kenya may still contain TPO, particularly those manufactured for regions without bans. However, many global manufacturers are reformulating products to exclude TPO, aiming for broader market access.

Additional Considerations

• Gel nail curing involves UV or LED light exposure, which carries its own safety considerations, including potential skin effects.
• Acrylates and methacrylates in gel formulas can cause allergic reactions if uncured material contacts the skin.
• Consumers and professionals are encouraged to check product ingredient lists or safety data sheets to confirm the presence or absence of TPO.

While the ban targets TPO specifically, it does not prohibit gel manicures overall. The industry is shifting to alternative photoinitiators to maintain product performance without TPO.

For Kenyan consumers and nail technicians, awareness of ingredient content and regulatory developments is essential to ensure safe and compliant use of gel nail products.
