Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the key biodegradation study (OECD Guideline 301F with GLP compliance), even if the registered substance attained only 59% and 47% degradation after 28 days in the tests 1 and 3, the registered substance attained 65% degradation after 28 days without fulfilling the 10 -day window validation criteria in the test 2. According to the OECD Guidelines, a mixture containing isomers that are expected to degrade sequentially is not required to meet the 10 -day window obligations and therefore, as the degradation was greater than 60% after 28 days, the registered substance can be considered to be readily biodegradable. A positive biodegradability test is sometimes difficult to obtain because it's dependent on the quality of the inoculum used. Therefore, a positive result is sufficient to conclude on the readily biodegradation potential of the substance. This conclusion is supported by an additional study on an extremely similar source substance where clear ready biodegradability was observed.
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.
