Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
The percentage degradation of test substance was determined to be 70 and 87 % by BOD and 100 % by TOC removal and HPLC parameter in 14 days. Thus, based on percentage degradation, test chemical was considered to be readily biodegradable in water.
Biodegradation in water and sediment:
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end point is scientifically not necessary and does not need to be conducted since the test chemical is readily biodegradable in water.
Biodegradation in soil:
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end point is scientifically not necessary and does not need to be conducted since the test chemical is readily biodegradable in water.
Additional information
Biodegradation in water:
Summarized result for the determination of biodegradation of test chemical and structually and functionally similar read across chemicals in water are as mentioned below:
In the first key study from authoritative database, biodegradation study was conducted for 14 days for evaluating the percentage biodegradability of test substance. Activated sludge was used for the study. Concentration of inoculum i.e, sludge used was 30 mg/l and initial test substance concentration used in the study was 100 mg/l, respectively. The percentage degradation of test substance was determined to be 70 and 100 % by BOD, TOC removal and HPLC parameter in 14 days. Thus, based on percentage degradation, test chemical was considered to be readily biodegradable in water.
Above study further supported by the second study from authoritative database. Biodegradation study was conducted for 14 days for evaluating the percentage biodegradability of test substance. Activated sludge was used for the study. Concentration of inoculum i.e, sludge used was 30 mg/l and initial test substance concentration used in the study was 100 mg/l, respectively. The percentage degradation of test substance was determined to be 87 % by BOD and 100% by TOC removal and HPLC parameter in 14 days. Thus, based on percentage degradation, test chemical was considered to be readily biodegradable in water.
Thus, on the basis of above all studies, the percentage degradation of test substance was determined to be 70 and 87 % by BOD and 100 % by TOC removal and HPLC parameter in 14 days. Thus, based on percentage degradation, test chemical was considered to be readily biodegradable in water.
Biodegradation in water and sediment:
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end point is scientifically not necessary and does not need to be conducted since the test chemical is readily biodegradable in water.
Biodegradation in soil:
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end point is scientifically not necessary and does not need to be conducted since the test chemical is readily biodegradable in water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
