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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is not classified as a « difficult test substance » according to the OECD Guidance document.
In the table below are summarized the results of aquatic toxicity studies performed:
| Items | ||
| Short-term toxicity to fish | LC 50 | >100mg/L |
| Short-term toxicity to aquatic invertebrtes | EC 50 | The immobility of the most daphnias was affected by deposits of the test substances of their body. Therefore EC50 could not be determined. |
Microorganism Toxicity: The IC50 of the test substance in the activated sludge respiration inhibition was >100 mg/l. NOEC was >= 100 mg/l (nominal concentrations). The IC50 and NOEC values are above the detection limit of the substance.
Conclusion on classification
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.
