Deca-BDE is currently in the pre-registration phase under REACH.
Deca-BDE has already been the subject of an evaluation under the ESR Risk Assessment procedure, which was concluded without recommendation for restrictions, thanks to the lack of significant risks identified for the use of this substance (add link to section 4.1.2). The Risk Assessment was finalised and published on the EU Official Journal in May 2008. The results of the Deca-BDE Risk Assessment will be transferred into REACH, most probably without need for further studies.
More information on the studies performed during the Deca-BDE Risk Assessment can be found on the website of BSEF.
