Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The bioconcentration factor of bis(2 -ethylhexyl)maleate was calculated according to the requirements stated in the IR & CSR by using a bilinear formula which is recommended for substances with a log Pow above 6. The resulting BCF value of 4073.8 L/kg indicates that bis(2 -ethylhexyl)maleate has the potential to bioaccumulate in the aquatic environment, and hence fulfils the "B" criterion as defined in the legislation. As the calculated BCF value is clearly above the BCF value of 2000 L/kg triggering the "B" criterion, it is assumed that an in vivo testing would also result in a value clearly above 2000 L/kg. Due to animal welfare reasons, it is not justified to conduct a test just for the confirmation of already existing data. Besides this, bis(2 -ethylhexyl)maleate is used exclusively as intermediate or monomer, respectively, where only low release into the environment can be expected. Also for this reason it is justified not to conduct an in vivo bioaccumulation study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
