Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation in water
Estimation Programs Interface Suite (2018) was run to predict the biodegradation potential of the test chemical in the presence of mixed populations of environmental microorganisms. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Timeframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that test chemical is expected to be not readily biodegradable.
Additional information
Biodegradation in water
Predicted data for the test chemical and supporting study for its structurally similar read across substance were reviewed for the biodegradation end point which are summarized as below:
In a prediction using the Estimation Programs Interface Suite (2018), the biodegradation potential of the test chemicalin the presence of mixed populations of environmental microorganisms was estimated. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Timeframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that test chemical is expected to be not readily biodegradable.
For the test chemical from authoritative database (2017),biodegradation study was conducted for 72 days for evaluating the percentage biodegradability of test chemical by using municipal waste waterplant from outfall on Fourmile Creek near Ankeny, as a test inoculum. The percentage degradation of the test chemical was determined to be 0% degradation by considering test material analysis (14CO2 (N-methyl-labeled) as parameter in 72 days. Thus, based on the percentage degradation, the test chemical was considered to be not readily biodegradable in water.
On the basis of above results for test chemical, it can be concluded that the test chemical can be expected to be not readily biodegradable in nature.
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.
