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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance does not have the potential to bioaccumulate. In a study according to EU Method A.8, OECD Guideline 107 (Partition Coefficient (n-octanol / water), shake-flask Method) the octanol-water partition coefficient was determined to be logPow = 0.9 at 25°C measured with GC/FID. A further study was carried out to assess the biodegradation properties of the test item. In a study according to OECD Guideline 301 D (Ready biodegradability: Closed Bottle Test) the test item did not reach the pass level of 60 % within two weeks. Therefore, the test item was considered to have exceeded the ready biodegradability pass level of 60 % ThODNH3 removal within 28 days, but the 14 day window criterium was not met. However, it may be characterized as inherently and ultimately degradable on the basis of these test results.
Key value for chemical safety assessment
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.
