Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
To assess the biotic degradation of the registered substance, a weight of evidence approach was performed with six ready biodegradability tests using different OECD Guideline test methods. Based on these studies, the registered substance is not considered readily biodegradable but strong and consistent evidence of significant mineralisation to the main degradation product, Delta-Damascone mercapto acetic acid (DD-ma) was provided. All larger metabolites found (e.g. Delta-Damascone mercapto propionic acid (DD-mp)) can be considered as transient intermediates. Therefore, the registered substance is considered inherently biodegradable (not fulfilling specific criteria) and not persistent. The principal metabolite, DD-ma, is slowly degraded and in the absence of other biodegradation study on this metabolite, DD-ma is considered as potentially persistent (P) or very persistent (vP).
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.
