Description of key information
The acute toxicity of the substance to fish (Danio rerio) was tested in a static test. After 96 hours of exposure, a LC0 of ≥100 mg/L and a LC100 of >100 mg/L were determined. A LC50 of >100 mg/L was calculated.
Key value for chemical safety assessment

The study was conducted in accordance with Council Regulation (EC) No 440/2008, Method C.1 'Acute toxicity for Fish' (2008) which is in most parts equivalent to the OECD Guideline for Testing of Chemicals No. 203 'Fish, Acute Toxicity Test' (1992).
A group of seven fish of the recommended size was exposed to a limit test concentration of nominally 100 mg/L of the substance dissolved in dilution water. Auxiliary used to prepare the test medium was a magnetic stirrer. Observations were made on the number of dead fish and the incidence of sub-lethal effects after 2, 24, 48, 72 and 96 hours of exposure. No toxic effects against fish were observed at a limit test concentration of 100 mg/L under exposure conditions. All results are expressed in terms of nominal concentrations. Effective concentrations correspond to 95.5 % of nominal values at 0 hours and to 94.6 % of nominal values at 96 hours. The substance does not have a definite or unique structure and consists of several components. No information about the correlation between molecular weight and the structural formula of the test item are available.
This toxicity study is classified acceptable and satisfies the guideline requirements for acute toxicity to fish.
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.
