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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Further biodegradation testing, including biodegradation simulation testing in soil, is waived in accordance with Regulation (EC) No.1907/2006, Annexes VIII and IX , Column 2.
Key value for chemical safety assessment
Additional information
According to Regulation (EC) No.1907/2006, Annexes VIII and IX, Column 2, further biodegradation testing, including testing for ultimate biodegradation in soil, need not be conducted if direct and indirect exposure to soil is unlikely. The predicted Koc for the substance is 4.913; this value falls substantially below the range of Koc values of 500-1000, below which substances are unlikely to adsorb to soil. The chemical safety assessment did not indicate the need to investigate the degradation of the substance; the risk characterisation ratios for soil are below one. Therefore, in accordance with Annex I, the risks are considered to be controlled.
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.
