Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Ready biodegradability
Key, OECD 301 C, GLP, 4.56% in 28 days (based on HLPC-PDA analysis of residual test substance): not readily biodegradable
Additional information
The biodegradation in water, screening test was performed according to OECD Guideline 301C under GLP compliance. Inoculum used in this study was collected from 11 sites in Korea including 5 rivers (Gangjeong, Mulgeum, Gwangju, Daejeon, Paldang), 4 domestic sewage treatment plants (Dalseo, Gumi, Busan, Jungrang) and 2 industrial wastewater treatment plants (Dalseo, Yeosu). The biodegradation test was conducted according to the SOP of “Biodegradation test” and the oxygen uptake was measured by the BOD meter equipped with 6 bottles. Reference compound, Sodium benzoate, was used to check the microbial activity of treated inoculums.
The test substance could not be concluded as readily degradable by microorganisms in the aquatic environment. The average percentage biodegradation of the test substance by BOD measurement after 28 days was calculated to be 0.0 % which was less than pass level of biodegradability (60%) specified by the OECD Guideline.
The percentage biodegradations based on the residual amount of test substance by HPLC-PDA analysis was calculated to be 4.65 %.
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.
