Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are several studies available on ready biodegradability. These were conducted according to OECD guideline 301 B-E. Four results clearly indicate that MCA is readily biodegradable, i.e. 60 -70% within a time-window of 10 -14 days. This result is also supported by the inherent biodegradation results. In all inherent test MCA was (nearly) 100% biodegraded between 6 and 28 days.
One biodegradability study performed under anaerobic conditions (Egli, 1989) showed that MCA is also rapidly degradable under these conditions. Measured rates of reduction of 86 -90% within 2 days at 34 °C were found.
Under aerobic as well as anaeroobic conditions MCA is fully mineralized.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
Additional information
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.
