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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates

Description of key information
Two studies have been done following EU Test method C.2 and a third one is available done according to OECD Guideline 202
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 0.7 mg/L
Additional information
The details on the performance of the tests are not well detailed but the low solubility of the substance difficults the performance of the tests.
The results available are:
1) EU Method C2, EC50 (48h) > 0.1 mg/L
2) EU Method C2, EC50 (24h) >=0.7 mg/L (testing at nominal concentration of 1000 mg/L, supersaturation of the media)
3) OECD 202, EC (48h) > 0.2 mg/L and NOEC 0.2 mg/L (testing at nominal concentrations 100, 500 and 1000 mg/L shows any inherent toxicity)
In the three studies the EC50 and NOEC are at levels up to the limit of water solubility.
When working under supersaturation conditions no acute toxic effects have been observed.
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.
