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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Acute toxicity to fish
The 96 -h LC50 (Onchorhynchus mykiss) was determined to be > 100 mg/L (OECD 203, ASTA Medica AG, 1998). Therefore, the substance is with high probability acutely not harmful to fish.
Acute toxicity to aquatic invertebrates
The 48 -h EC50 (Daphnia magna) was determined to be > 100 mg/L (OECD 202, ASTA Medica AG, 1998). Therefore, the substance is with high probability acutely not harmful to aquatic invertebrates.
Toxicity to algae and cyanobacteria
The 72 -h ErC50 (Desmodesmus subspicatus) was determined to be > 100 mg/L (OECD 201, BASF AG, 2004). The ErC10 is also above the highest tested concentration of 100 mg/L. Therefore, the substance is with high probability acutely not harmful to algae.
Toxicity to microorganisms
The 180 -min EC20 (activated sludge, domestic) was determined to be > 1000 mg/L (OECD 209, BASF AG, 2004). Additionally, the 16 -h ErC10 (Pseudomonas putida) was determined at 7700 mg/L (ASTA Medica AG, 1993). Therefore, no inhibition of the degradation activity of activated sludge is anticipated if the substance is introduced in appropriately low concentrations.
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.
