Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 acute fish limit test was performed applying a nominal loading rate of 8 mg/L test item which was, therefore, even higher than the threshold test item loading rate (ELR50 (48 h) from the Daphnia magna Acute Immobilisation Test). The absence of any mortality as well as no observable effects of appearance and behavior in the present study indicates that, according to the Threshold Approach for Acute Fish Toxicity, fish is not the most sensitive group of test organisms after short-term exposure and no further testing is required.
The two components of the test item are not stable and hydrolyse in aqueous medium with formation of the correspondent hydrolysis products. Any deviation from pH 7 will accelerate the hydrolysis. The test organisms were most likely exposed to a mixture of the two parent components and their correspondent hydrolysis products.
As a consequence of these described test item properties and conditions, it is adequate to calculate the effect concentrations in relation to the nominal test item loading rates.
The NOEL (96h) >= 8 mg/l tested with danio rerio

Additional information
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.
