The TPO ban in GB is an important update for beauty professionals and manufacturers working under the UK Cosmetics Regulation. gcrs group has reviewed the changes and explains what this ban means for those using or selling cosmetic products that contain trimethylbenzoyl diphenylphosphine oxide (TPO).

Understanding the TPO Ban in GB

The ‘making available’ (off-shelf) date for products containing TPO will begin on 15 February 2027.

According to gcrs group’s interpretation, beauty professionals may keep using products that include TPO after this date, if they bought them before the deadline. However, distributors and suppliers must stop selling these products once the off-shelf date arrives.

This ensures that existing products can still be used safely while preventing further distribution.

Why Has the TPO Ban Been Introduced in GB?

The TPO ban in GB follows its reclassification under the GB CLP (Classification, Labelling and Packaging) Regulation. TPO is often used in gel nail and UV-cured cosmetic products as a photoinitiator.

Regulators based this restriction on a “worst-case scenario” risk model, rather than how TPO is actually used in cosmetics. In practice, very small amounts of TPO are used, and exposure to consumers is minimal.

Before products reach the market, qualified safety assessors test and confirm their safety. Moreover, the Scientific Committee on Consumer Safety (SCCS) reviewed TPO in 2014 and concluded that it is safe when used correctly.

Compliance After the TPO Ban in GB

Once the new rule takes effect:

• Professionals can continue using existing stock.

• New sales will stop after 15 February 2027.

• Distributors must remove affected products from their shelves.

This transition gives the industry time to adjust. It also ensures continued compliance with UK and GB cosmetic regulations.
