Description of key information
In a static acute toxicity test performed in accordance with OECD TG 203 using fathead minnows, the 96-h LC50 was > 100 mg/L based on nominal concentrations. There were no visible signs of toxicity at any dose used.
Key value for chemical safety assessment
Additional information
In a static 96-hour acute toxicity study performed in accordance with OECD TG 203 and US OPPTS 8500.1075, fathead minnows (10 fish per dose) were exposed to the substance, dissolved in DMF, at nominal concentrations of 6.3, 13, 25, 50 and 100 mg/L (2 replicates). A blank negative control and a solvent control were run in conjunction with the test.
There was no analysis of the test concentrations. All results were therefore based on the nominal concentrations.
The results showed that at the nominal test concentrations of 100 mg/L and below the substance produced no visible indication of toxicity after 96 hours exposure. The study met the acceptability criteria and was considered valid.
Under the conditions of the study, the substance produced no visible effects of toxicity in fathead minnows at or below the highest concentration tested. The LC50 (96h) > 100 mg/L and the NOEC is 100 mg/L based on nominal test 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).
