Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
Additional information
No sediment toxicity data are currently available for the registered substance.
Long-term sediment toxicity studies are not required for Annex IX substances under the REACH Regulation. However, due to the high sediment adsorption potential of the substance and the potential for persistence in the sediment, the potential significance of this compartment has been assessed. It is concluded that further consideration is not required because:
- The physicochemical properties and high value of Koc means that if the substance were to enter a wastewater treatment plant in influent waste waters, it would partition mainly to sludge (a small proportion may be volatilised), with a negligible amount passing to water. The result is that exposure of freshwater or marine sediment compartments is negligible.
- The substance is not manufactured or used as such in the EU and is registered in accordance with the REACH Regulation (Article 6) in order to support import of polymers. Residual unbound monomer in polymer is very low and the substance is of extremely low water solubility, such that unintentional release to the aquatic environment from end use of the polymers is negligible.
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.
