Additional information
Conclusion on classification
Acute toxicity:
Fish is the most sensitive species to the acute toxic effects of the test item with an acute EC50 of >100 mg/L. Based on the these data, the substance has not to be classified with regard to acute environmental toxicity according to Regulation (EC) No 1272/2008 (CLP/GHS)
and according to Directive 67/548/EEC (DSD).
Chronic toxicity:
Algae are the most sensitive species to toxic long term effects of the test item with a chronic NOEC of 74 mg/L. As the test item is inherently biodegradable, the NOEC is above the threshold value of 1 mg/L and all short therm acute toxicity EC50 of the three trophic levels were above 100 mg/L, the substance has not to be classified with regard to chronic environmental toxicity according to Regulation (EC) No 1272/2008 (CLP/GHS) and according to Directive 67/548/EEC (DSD).
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).
