Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Only the biodegradation of the test substance in water was analysed using OECD guideline 301B. The study indicates that the substance was found to not be readily biodegradable. Due to the low water solubility of the test item it was spread across the surface of a glass coverslip which was then added into the inoculated mineral medium. By day 14 the toxicity control was found to have 34 % biodegradation, indicating that the test item is not inhibitory to the degrading organisms. Under the test conditions, the substance was found to be not readily biodegradable after 28 days showing an average of 10 % degradation from 2 replicates. The study was extended to 60 days and upon analysis at termination showed and average of 24 % degradation. The results from the test show that the substance is not ready biodegradable. However, poorly-water soluble substances often display limited bioavailability to competent degraders causing the tested substance to not degrade.
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.
