Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 701-204-9 | CAS number: -
Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Based on the results of two reliable studies, EC 701 -204 -9 would not be considered readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Two reliable OECD 301 B tests were available for the registered substance. The ready biodegradability of the test material was determined by the measurement of CO2 evolution in both studies. In the Haberlein & Schaefer, 1998 study, the amount of CO2 produced by the test material at a concentration of 10 mg/L (determined by carbon content) after 28 days indicated negligible biodegradation (5%). In the Marks, 1994 study, the amount of CO2 produced by the test material at concentrations of 10 and 20 mg/L (determined by direct weighing) were 21.8 and 4.5%, respectively after 28 days. Therefore, the test material can be classified as not readily biodegradable and the results are considered adequate for risk assessment and classification and labelling purposes.
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.
