ADCA REACH Consortium

The ADCA Task Force has been set up to organise ADCA producers and downstream users to respond to regulatory challenges under REACH. 
The Task Force has now over 40 members throughout all major supply chains – and comprising companies from the various steps: manufacturers, importers, formulators and compounders, article producers.

What is at stake?

ADCA has been identified as Substance of Very High Concern (SVHC) due to its classification as respiratory sensitizer and included to the Candidate List in December 2012.

Since the listing, ADCA has been considered for inclusion in Annex XIV of the REACH Regulation (inclusion in Annex XIV will trigger the REACH authorisation process).

  • An initial decision was taken in 2016 to postpone the listing of ADCA in Annex XIV. The European Commission decided to re-open this discussion in 2018 but it was again decided to postpone the Annex XIV listing.  
  • While it appears unlikely in the short term that ADCA will be listed in Annex XIV, if such a decision is taken by the European Commission, this will mean that in order to use ADCA in your applications, each use will need to be authorised – either by yourself or by your supplier.

ADCA has also been identified as a substance for future scientific evaluation with a view to agreeing an OEL, within the priority list of chemicals under the Chemical Agents Directive 98/24/EC (CAD). No date has been given to start this evaluation for ADCA.

If you are a user of ADCA, please consider joining the Task Force to:

  • support the common industry input on regulatory developments that may impact ADCA at the EU and Member State level
  • make sure your supply chain and your company’s interest is represented in the Task Force
  • be prepared prepared to manage any development that may impact the future use of ADCA (e.g. OEL setting, SVHC status, authorisations or restrictions)

The Task Force is managed by ReachCentrum.
