Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data on the toxicity to terrestrial plants are available. In a seedling emergence and seedling growth test with three plant species (wheat, rape and lettuce), the test substance had no effect on the germination rate or on the growth of the plants up to and including the highest test concentration of 100 mg/kg soil dry weight. No visual phytotoxic symptoms were observed for all species up to and including the highest test concentration of 100 mg/kg soil dry weight. Therefore, the 14 -day NOEC for emergence and growth was 100 mg/kg soil dry weight, the LC50 for emergence was > 100 mg/kg soil dry weight and the EC50 for growth was > 100 mg/kg soil dry weight. Since no toxic effects occurred up to the highest tested concentrations, toxicity to other terrestrial organisms are not expected either. However, an environmental exposure assessment was performed in order to determine possible risks of the test compound to all environmental compartments. According to the results of the exposure assessment, all the relevant uses of the test substance are considered to be safe with a Risk Characterization Ratio below 1.
Therefore, studies on the toxicity to other terrestrial organisms are not provided.
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.
