Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A key study for readily biodegradability is waived and the substance is treated to be not readily biodegradable as the worst case. This is supported by the available study (Scholtz 1996, Reliability 3), which was not performed according to guidelines or GLP criteria. Furthermore, the conclusion of non-ready biodegradability is supported by the results of QSAR models (BIOWIN). Both BIOWIN 1 (= 0.2423, Linear model) and BIOWIN 2 (= 0.0076, Non-linear model) showed values less than the cut-off point (0.5). Thus, the substance is not readily biodegradable according to ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7b: Endpoint specific guidance (Version 4.0 June 2017).
The biodegradation of the substance in surface water: simulation test is waived as the chemical safety assessment does not reveal a need for further investigation based on the available information. In addition, the key study for the biodegradation in water-sediment endpoint showed that the substance was quickly adsorbed from the water phase to the sediment phase (Völkel 1997, Reliability 2). The same study from Völkel (1997) also concluded that the geometric mean DT50 for the test substance in the whole water-sediment system was 1047 days. The results from a study under non-standard conditions support this conclusion, which showed DT50 was around 7 months for the test substance in the sediment compartment (Gampp 1989, Reliability 1). The geometric mean DT50 for the test substance to be biodegraded in soil was calculated to be 117 days based on six aerobic studies that cover 18 soils (Glänzel 1994, Glänzel & Wission 1994, Wission 1992, Oliver & Edwards 2007, Barizon 2007 and Kuet 2006; Reliability 1).
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.
