Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
OECD Procedure 301F ‘Ready Biodegradability, Manometric Respirometry Test and Method C.4-D: EP-4000S was not considered to be readily biodegradable under the conditions of this test.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A ready biodegradability screening test was conducted (Huntingdon Life Sciences,2012) to assess the potential for EP-4000S to be degradaed over a 28 -day period. The study was performed according to OECD test guideline 301F (Ready Biodegradability, Manometric Respirometry Test) and in compliance with GLP.
There was no significant oxygen consumption in mixtures containing EP-4000S above that of the control mixtures during the test (at most 0.03 mgO2/500 mL).
Substances are considered to be readily biodegradable in this type of test if oxygen consumption is equal to or greater than 60% of the ThOD of the mixtures within ten days of the consumption achieving 10%. Therefore, EP-4000S was not considered to be readily
biodegradable under the conditions of this test.
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.
