Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Conclusion on classification
Environmental fate and pathways
Degradation
Not readily biodegradable: 11% and 20% after 28 d (OECD 301B)
Bioaccumulation
Log Kow = < -5.1 at 19.9 °C (OECD 107, estimation method).
Aquatic acute toxicity
Fish
LC50 (96 h) = 6.4 mg/L (nominal, Standard methods for the Examination of Water and Wastewater, 13 th Edition, USA, Pimephales promelas)
Aquatic invertebrates
EC50 (48 h) = 3.2 mg/L (nominal, OECD 202, Daphnia magna)
Algae
EC50 (7 d) = 0.4 mg/L (yield, Selenastrum capricornutum, modification of the provisional algal assay procedure (PAAP))
Classification according to CLP
Based on the data above the substance is not rapidly degradable and has a low potential for bioaccumulation. Based on the data for aquatic toxicity the substance needs to be classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 1 (H410) for environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).
M-factor for acute aquatic toxicity: 1
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
