Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
In a standard screening biodegradation test (CO2 evolution test; OECD testing guideline 301B), the percentage of biodegradation of test material was determined at 9% based on TCO2 after 29 days of exposure.
In a sealed vessels carbon dioxyde production test (ISO 14593 and EPA OPPTS 835.3120 guidelines) , the percentage of biodegradation of test material + silicone oil was 37 % based on inorganic carbon analysis after 56 days of exposure.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
In a standard screening biodegradation test (CO2 evolution test; OECD testing guideline 301B), the percentage of biodegradation of test material was determined at 9% based on TCO2 after 29 days of exposure. E96095 does not meet the readily biodegradable criterion. (Burwood, 1999).
In a sealed vessels carbon dioxyde production test (ISO 14593 and EPA OPPTS 835.3120 guidelines) , the percentage of biodegradation of test material with inert carrier (silicone oil) was 37 % based on inorganic carbon analysis after 56 days of exposure. Primary biodegradation of E96095 has been observed when enhancing measures are used to improve its bioavailability and the incubation period is extended longer than the standard 28 -day ready biodegradation screening test (Barnes, 2008).
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.
