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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water and sediment: simulation tests

Description of key information
In accordance with Section 9.2.1.2, Column 2, Annex IX of Regulation (EC) No. 1907/2006, simulation testing on ultimate degradation in surface water need not be conducted if the substance is highly insoluble in water. The directly-measured water solubility of Catalyst 21513 (0.003 mg/L) demonstrates that the substance is highly insoluble in water (< 0.1 mg/L). Therefore, simulation testing in surface water is not indicated.
In accordance with Section 9.2.1.4, Column 2, Annex IX of Regulation (EC) No. 1907/2006, sediment simulation testing for substances with a high potential for adsorption to sediment need not be conducted if direct and indirect exposure of the sediment is unlikely. Since the chemical safety assessment did not indicate the potential for a harmful effect upon sediment organisms, sediment simulation testing is not indicated.

Additional information
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.
