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
48 h EC50 = > 100 mg/L, 48 h NOEC = 100 mg/L, Daphnia magna, OECD 202, EU Method C.2, L'Haridon 2002
Key value for chemical safety assessment
Additional information
The acute toxicity of the test material to aquatic invertebrates was investigated with Daphnia magna in accordance with standardised guidelines OECD 202 and EU Method C.2. The Daphnia were exposed to the test material at concentrations of 0, 0.1, 1, 10 and 100 mg/L, under static conditions, for a period of 48 hours. Immobilisation of daphnia was recorded at 1, 24 and 48 hours. Under the conditions of the test no immobilisation occurred up to the limit concentration of 100 mg/L. The 48 hour EC50 of the test material was therefore determined to be in excess of 100 mg/L. The 48 hour NOEC of the test material to Daphnia magna was determined to be 100 mg/L.
The study was performed in line with GLP and accepted standardised guidelines with a high standard of reporting. The study was assigned a reliability score of 1 according to the criteria of Klimisch (1997) and considered suitable for assessment as an accurate reflection of the test material.
The available data are considered to be complete and the result determined, 48 hour EC50 value greater than 100 mg/L, 48 hour NOEC value 100 mg/L,was taken forward for risk assessment.
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).
