Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Aquatic toxicity
Acute toxicity data for the test item are available for two trophic levels, daphnia and algae. The relevant acute effect values were the 72-h ErC50of > 100 mg/L and the 48-h EC50of > 100 mg/L (based on nominal dissolved test item concentration) observed for the effect of the test item on growth inhibition ofPseudokirchnerella subcapitataand on immobilization ofDaphnia magnain GLP-conform standard tests according to OECD 201 and 202. These values are selected as the acute reference values for classification.
Chronic toxicity data for the test item are available for one trophic level, algae. The chronic 72-h EC10for algae is > 100 mg/L (based on nominal dissolved test item concentration) for the effect of the test item on growth rate ofPseudokirchneriella subcapitatain a GLP-conform standard test according to OECD 201. This value was selected as chronic reference values for classification, as well as for the second trophic level, the acute 48-h EC50of > 100 mg/L (based on nominal dissolved test item concentration) forDaphnia magna,the non-readily biodegradability and the calculated logPow of 2.76.
Acute (short-term) aquatic hazard based on acute data:
48h-EC50> 100 mg/L (daphnia)
72-hour ErC50> 100 mg/L (algae)
Based on this reference value, no classification for ACUTE/SHORT-TERM AQUATIC HAZARD is required according to Regulation (EC) No 1272/2008 and subsequent regulations and Directive 67/548/EEC and its subsequent amendments.
Chronic (long-term) aquatic hazard based on chronic & acute data and environmental fate:
72 -hour ErC10> 100 mg/L mg/L (algae - chronic data)
48-hour EC50> 100 mg/L mg/L (daphnia - acute data)
not readily biodegradable
logPow 2.76
Based on these data, no classification for CHRONIC/LONG-TERM AQUATIC HAZARD is required according to Regulation (EC) No 1272/2008 and subsequent regulations and Directive 67/548/EEC and its subsequent amendments.
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).
