Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: Key study. Method according to OECD 301F / EU Method C.4 -D, GLP study. The 28 day biodegradation of the test item is 9.2% and therefore, it is not readily biodegradable.

Additional information

A study of ready biodegradability of the test according to OECD 301F / EU Method C.4–D (GLP study) was performed. 30 mg/L of activated sludge were exposed to 100 mg/L of test item during 28 days, under aerobic conditions at 22ºC. Blank tests (only inoculum), and procedure tests with a reference item (sodium acetate) were run in parallel to check the operation of the procedures. To check the possible inhibitory effect of the test item, a toxicity test was run in parallel. After correction for oxygen uptake for interference by nitrification and by the blank inoculum control, the final biodegradation of the test item on the 28th test day was 9.2%. Therefore, the substance is not readily biodegradable under test conditions. In the toxicity test, a 35% biodegradation was attained after 28 days and, therefore, the test item is not assumed to be inhibitory.
