Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
With high probability acutely not harmful to invertebrates.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Dose descriptor:
- EC50
- Effect concentration:
- > 559.6 mg/L
Additional information
The EC50 (48 h) was determined to be > 559.6 mg/L (meas.) in a GLP guideline study with Daphnia magna according to OECD guideline 202 (Eastman 1995). The exposure conditions were static. The test concentrations were analytically verified and remained stable over the exposure period of 48 h (94 to 113 % of nominal).
This result is supported by a guideline study according to EU method C.2 using Daphnia magna as test species. The 48-h EC50 was determined to be > 500 mg/L (nom., BASF AG, 1988). The exposure conditions were static. Test concentrations were not analytically verified, but can be assumed to have remained within 80 to 120% of nominal concentrations based on the results of the key study (Eastman 1995).
Based on these results the substance is with high probability acutely not harmful to aquatic invertebrates.
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.
