Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation in water: screening tests: 83% (oxygen consumption); OECD 301C.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Key data: Biodegradation of 83% (oxygen consumption) within 28 days was determined in a reliable study conducted according to an appropriate test protocol (OECD Guideline 301C), and in compliance with GLP.
Biodegradation of 83% was measured by biological oxygen demand (BOD) in a 28 day study conducted according to OECD 301C and in compliance with GLP. Abiotic (primary) degradation of 30% was measured by HPLC, and the degradants (hydrolysis products) identified as acetophenone and acetic acid. Both degradants are readily biodegradable. Biodegradation of 98% was measured by dissolved organic carbon (DOC) analysis.
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.
