Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Valid acute toxicity tests with the test substance or a structural similar read-across substance are available for three freshwater species from three trophic levels. In all tests no effects within the water solubility of the test substance were observed.
In the algae study no effects were observed in the tested undiluted filtrate with a loading rate of 100 mg/L (NOEC >= 0.0089 mg/L). In the Daphnia study no effects were observed in the saturated solution (100 mg/L loading rate). The EC50 (48h) of the test item to daphnia is > water solubility.
In all three fish tests with a structural similar substance no mortality was observed within water solubility. The key study (Scheerbaum, 1996) showed that even in an emulsion with 100 mg/L nominal, no effects were observed (LC50 > 82 mg/L measured conc.). A study using an emulsifier (Caspers, 1996) showed as well no mortality up to the water solubility limit (LC0 >= 0.22 mg/L; loading rate 2.5 mg/L). In a third study (Caspers, 1992) the toxicity was tested far above the water solubility of the substance (62 to 1000 mg/L). Up to 250 mg/L (nominal) no mortality was observed. The LC50 was determined to be 613 mg/L (nominal), where the mortality can be attributed to physical effects instead of systemic effects.
The toxicity control in the 301F ready biodegradability test showed no inhibition of the microbial activity at a substance concentration of 40 mg/L. Therefore no further test on microbial toxicity was conducted and 40 mg/L used as NOEC.
Thus, no acute toxicity is expected for aquatic organisms within the water solubility of the test substance and above.
No long-term tests on aquatic toxicity are available, but as the substance is not stable in the aquatic environment and the chemical safety assessment does not indicate the need to investigate further the effects on aquatic organisms, long-term tests are not considered necessary.
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.
