Additional information
The key study, a GLP test according to OECD Guideline 211 (Daphnia magna Reproduction Test), was performed by BASF SE (2013; report no. 51E0454/11E137) and OXEA (2013). The 21 -d NOEC was determined to be 0.069 mg/L for the endpoint reproduction, based on analytically verified time-weighted mean concentrations. No significant mortality could be observed among the parent animals.
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.
