Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 ready biodegradability of the substance was investigated in 3 reliable studies in accordance with OECD 310 (2006) and in a reliable study in accordance with OECD 301B (1992). In addition, 4 supporting studies are available (of reliability 4), performed similar to OECD 301B, similar to OECD 301E and similar to ISO 14593. Based on the results of all these 8 studies, the substance is not readily biodegradable (35-53% degradation after 28 days).
The inherent biodegradability of the substance was investigated in a reliable study in accordance with OECD 302B (1992) and according to GLP principles and in 3 supporting studies (of reliability 4) that were conducted similar to OECD 302B. In all these 4 studies it was found that the substance is inherently, primarily biodegradable under the conditions of the 'Zahn-Wellens / EMPA test' as a biodegradation of 55-60% after 28 days was recorded in these studies. The substance is therefore classified as “inherently biodegradable, not fulfilling specific criteria”.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
Ready biodegradability
The ready biodegradability of the substance was investigated in 3 reliable studies in accordance with OECD 310 (2006) and in a reliable study in accordance with OECD 301B (1992). In addition, 4 supporting studies are available (of reliability 4), performed similar to OECD 301B, similar to OECD 301E and similar to ISO 14593. Based on the results of these 8 studies, in which a biodegradation in the range of 35 - 53% after 28 days was recorded, the substance is not readily biodegradable.
Inherent biodegradability
The inherent biodegradability of the substance was investigated in accordance with OECD 302B (1992) and according to GLP principles. At the start of the study, the measured DOC concentration of the test solution was 238.9 mg/l. The results obtained during the test period showed no significant DOC removal in the first 3 hours of incubation, indicating no or limited adsorption to sludge during this period. The biodegradation values calculated from the DOC measurements performed during the 28 days test period revealed more than 20% biodegradation on day 3, and 60% at the end of the test period. All validity criteria were fulfilled. Based on the results of this study, the substance can be classified as “inherently biodegradable, not fulfilling specific criteria” in accordance with the ECHA Guidance documents.
This classification was also the result in 3 supporting studies (of reliability 4) that were conducted similar to OECD 302B, showing similar biodegradation results.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).
