Key takeaway

What This Development Means

Advocate General Ćapeta’s recommendation to revisit titanium dioxide’s carcinogen classification challenges the EU General Court's earlier annulment. This decision could significantly impact industries using titanium dioxide, emphasising the balance between scientific rigour and judicial oversight in chemical regulation.

What is the current status of titanium dioxide’s classification in the EU?

Titanium dioxide is no longer classified as a Category 2 carcinogen after the General Court annulled the European Commission’s decision in 2022. However, Advocate General Ćapeta recommends revisiting this ruling.

How will this decision affect industries using titanium dioxide?

If reclassified as a carcinogen, industries will face stricter labelling, packaging, and use restrictions, especially in products like paints, plastics, cosmetics, and toys. Compliance with safety data sheet updates and waste handling rules would also become mandatory.

The European Union's Advocate General Ćapeta published an opinion today, 6 February 2025, recommending the General Court reconsider its annulment of the classification of titanium dioxide as a Category 2 carcinogen. This decision could reshape chemical regulations, affecting manufacturers, downstream users, and industries reliant on titanium dioxide’s widespread applications.

Advocate General Ćapeta’s Position

‍Advocate General Ćapeta’s opinion focuses on the EU General Court's decision in 2022, which annulled the European Commission’s classification of titanium dioxide in powder form as a Category 2 carcinogen by inhalation. Ćapeta argues that the court erred by narrowly interpreting "intrinsic properties" and overstepping its role by replacing regulatory scientific assessments with its own.

Ćapeta stated in her opinion

"The General Court cannot therefore replace its scientific assessment for that of the Commission. In doing so, it would encroach on the jurisdiction of the administration."

Implications For Industry Stakeholders

‍Titanium dioxide is a key component in numerous sectors, including:

Cosmetics: Sunscreens and toothpaste.Coatings and Paints: High-opacity pigments for brightness and durability.Plastics and Packaging: UV-resistant properties for long-lasting products.

If the classification is reinstated, businesses will face compliance challenges, including labelling, packaging updates, and restrictions on use in toys, cosmetics, and more. The decision could also affect waste categorisation and limit eligibility for eco-certifications like the EU Ecolabel.

A Regulatory Precedent In The Making?

‍The broader concern lies in how the EU handles science in policymaking. Ćapeta’s recommendation reinforces the importance of maintaining trust in regulatory authorities like ECHA while ensuring judicial oversight does not hinder scientific progress. Stakeholders should watch for further developments as the case returns to the General Court for review.
