Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test item is poorly biodegradable.
Key value for chemical safety assessment
Additional information
The test item was investigated for its biodegradability in the "28-Day Modified Sturm Test" according to OECD guideline 301B and GLP requirements (RCC 1996).
The test item was found to be slightly biodegradable by 13.1 % by the end of the 28-day test period.
In the abiotic control, containing the test item and sterile test medium, a slight abiotic degradation of 9.4 % was noted by the end of the 28-day test period. In the toxicity control, containing both the test item and the reference compound Aniline, no inhibitory effect on the microorganisms was observed.
Comparable results were provided by another Modified Sturm Test performed with the test item by NOTOX B.V. (1996). Here, 14.7 -17.0% biodegradation was recorded after 28 days of incubation.
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.
