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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Fish, prolonged toxicity: 14-day study test
Under valid semi-static test conditions (72 h-renewal), the LOLC (the lowest observed lethal concentration), NOLC (the No observed lethal concentration), LOEC (the lowest observed effect concentration) and the NOEC (the No observed effect concentration) of the test substance were concluded as follows:
14 d-LOLC > 100 mg/L WAFs (measured concentration 1.83 mg/L);
14 d-NOLC = 100 mg/L WAFs (measured concentration 1.83 mg/L);
14 d-LOEC (behaviours) > 100 mg/L WAFs (measured concentration 1.83 mg/L);
14 d-NOEC (behaviours) = 100 mg/L WAFs (measured concentration 1.83 mg/L);
14 d-LOEC (weights & length) > 100 mg/L WAFs (measured concentration 1.83 mg/L);
14 d-NOEC (weights & length) = 100 mg/L WAFs (measured concentration 1.83 mg/L).
No effects were noted at the limit of solubility in water.
Fish juvenile growth: 28-day study test
Under semi-static conditions of 72 h-renewal, the effect on growth rates and other observed effects in juvenile fish (Gobiocypris rarus) exposed to the test substance for 28 days was conducted.
The results showed that under valid semi-static test conditions (72 h-renewal), no fish died in control and treatments groups. Fish in all treatments and control groups were observed alive and appeared normal. ln the 28d test period, the LOEC (lowest observed effect concentration) and the NOEC (No observed effect concentration) of the test substance to juvenile rare minnow were concluded as follows:
28 d-LOEC > 100 mg/L WAFs (measured concentration 1.79 mg/L);
28 d-NOEC = 100 mg/L WAFs (measured concentration 1.79 mg/L).
No effects were noted at the limit of solubility in water.
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.
