Conclusion on classification
Aquatic toxicity
Acute toxicity data for the test item are available for two trophic levels, daphnia and algae. The lowest acute effect value was the 48-h EC50 of 21.7 mg/L (based on dissolved test item concentration) observed for the effect of the test item on immobilisation of Daphnia magna in a GLP-conform standard test according to OECD 202. This value is selected as the acute reference value for classification.
Chronic toxicity data for the test item are available for one trophic level, algae. The chronic 72-h EC10 for algae is 16.5 mg/L (based on dissolved test item concentration) for the effect of the test item on growth rate of Pseudokirchneriella subcapitata in 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 EC50 of 21.7 mg/L (based on dissolved test item concentration) for Daphnia magna, the readily biodegradability and the logPow of 3.2.
Acute (short-term) aquatic hazard based on acute data:
48h-EC50 21.7 mg/L (daphnia)
72-hour ErC50 29.3 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.
Chronic (long-term) aquatic hazard based on chronic & acute data and environmental fate:
72 -hour ErC1016.5 mg/L (algae - chronic data)
48-hour EC50 21.7 mg/L (daphnia - acute data)
readily biodegradable
logPow 3.2
Based on these data, no classification for CHRONIC/LONG-TERM AQUATIC HAZARD is required according to Regulation (EC) No 1272/2008 and subsequent regulations.
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.
