ECHA adds a hazardous chemical to the candidate listThe Candidate List of Substances of Very High Concern (SVHC) now contains 241 entries for chemicals that may be harmful to humans or the environment. Companies are responsible for managing the risks of these chemicals and informing customers and consumers about their safe use.

June 27, 2024 – The newly added chemical is bis(α,α-dimethylbenzyl)peroxide. This substance is toxic to reproduction and is used as a processing aid, for example as a flame retardant.

Confirmation by MSC

The Member State Committee (MSC) of ECHA has confirmed the inclusion of this substance in the Candidate List. The list now comprises 241 entries. As some of these are groups of chemicals, the total number of chemicals concerned is higher.



This substance may be added to the authorization list in the future. If a substance is on this list, companies may not use it. Unless they submit an application for authorization and the European Commission allows further use.


Suspension of other substances

The MSC agreement process to identify triphenyl phosphate (TPhP; EC No. 204-112-2) as an SVHC was planned for the June Committee meeting. However, after consultation with Committee members and the dossier submitter, ECHA decided to suspend the process to find an agreement for this substance as significant new information became available in the days leading up to the meeting.
This suspension will ensure that the newly provided data is properly evaluated and included in the SVHC identification process. This is an exemption that only applies in the specific circumstances of this case.


Consequences of inclusion in the candidate list

Under REACH, companies have legal obligations if their substance – as such, in mixtures or in articles – is included in the Candidate List.
If an article contains a substance on the Candidate List in a concentration of more than 0.1% (weight by weight), suppliers must provide their customers and consumers with information on the safe use of that substance. Consumers have the right to ask suppliers whether the products they buy contain substances of very high concern.


For importers and producers

Importers and producers of articles must notify ECHA within six months of the listing date (June 27, 2024) if their article contains a substance on the candidate list.


For suppliers from the EU and the EEA

EU and EEA suppliers of Candidate List substances supplied individually or in mixtures must update the safety data sheet they provide to their customers.


Obligation to notify

According to the Waste Framework Directive, companies must also notify ECHA if the articles they manufacture contain substances of very high concern in a concentration of more than 0.1% (weight per weight). This notification is published in the ECHA database for Substances of Very High Concern in Products (SCIP).
