ECHA Adds Triphenyl Phosphate to the Candidate List: What You Need to Know
On November 7, 2024, the European Chemicals Agency (ECHA) added triphenyl phosphate (TPP) to its Candidate List of substances of very high concern (SVHCs), bringing the total number of chemicals on the list to 242. This substance has been identified as an endocrine disruptor, and is widely used as a flame retardant and plasticiser in various polymer formulations, adhesives, and sealants.
Uses and Risks of Triphenyl Phosphate
Triphenyl Phosphate (CAS No. 115-86-6) is commonly used in polymers, adhesives, and sealants. However, due to its endocrine-disrupting properties, it poses significant environmental and human health risks. ECHA had initially planned to discuss its inclusion in June 2024 but delayed the decision until October following the emergence of new information about the chemical’s properties.

Consequences of Inclusion on the Candidate List
The inclusion of a substance in the Candidate List comes with specific legal obligations under REACH. These obligations include:
- If a product contains a Candidate List substance above 0.1% concentration, suppliers must provide safety information on how to use the product safely.
- Consumers have the right to ask if products contain SVHCs.
- Importers and producers must notify ECHA within six months of the addition.
- Products containing these substances cannot bear the EU Ecolabel.
Potential Future Inclusion in the Authorisation List
Triphenyl Phosphate may be added to the Authorisation List in the future. If that happens, companies will need to apply for specific authorisation to continue using the substance after its inclusion in the Authorisation List.
ECHA’s addition of triphenyl phosphate to the Candidate List reinforces the importance of compliance with REACH regulations. Companies need to take necessary steps to ensure that they are meeting all legal requirements when dealing with substances of very high concern.
