Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the data from three trophic levels acute algae toxicity was identified as most severe and data on chronic algae toxicity in light of the availability of a chronic daphnia reproduction study with a higher NOEL was used to derive the PNECs for freshwater and marine water (due to lack of data on marine species).
The substance was not acutely toxic to microorganisms when tested according to OECD 301F, based thereupon, the PNEC STP was derived.
The PNECs for sediment, marine sediment and soil were derived by the partitioning method due to lack of data on sediment or soil organisms. Hazard to air is not expected.
As bioaccumulation potential cannot be excluded, a PNEC oral was derived based on the LOAEL of the subacute toxicity study performed according to OECD 422.
Conclusion on classification
Based on the results from chronic daphnia and algae tests, both resulting in NOELs above 1 mg/L and the ready biodegradability the substance has not to be classified for acute or chronic toxicity to aquatic organisms according to CLP (Regulation EC No 1272/2008) respectively according to DSD (Directive 67/548/EEC).
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).
