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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The key ecotoxicity values to assess the aquatic toxicity of the registered substance are as follow:
- Short-term toxicity to aquatic invertebrates: 48h-EC50 = 95.04 mg/L (Daphnia magna);
- Toxicity to aquatic algae: 72h-ErC50 > 100 mg/L and 72h-ErC10 > 100 mg/L ( Pseudokirchneriella subcapitata).
Those results are expressed as nominal concentrations, since the deviations between the measured concentrations and the nominal concentrations were within the range of ± 20 %
Based on these results, the lowest acute E(L)C50 is above 1 mg/L (between 10 and 100 mg/L). Therefore, the substance is not considered as acutely toxic to aquatic species according to CLP criteria.
Additional information
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).
Acute aquatic hazard: not classified. Reasoning: lowest E(L)C50 above 1 mg/L.
Chronic aquatic hazard: chronic category 3. Reasoning: adequate chronic toxicity data are not available, the lowest E(L)C50 is between 10 and 100 mg/L, the substance is not rapidly degradable.
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.
