Additional information
Oral
The oral acute toxicity study has been performed according to OECD 423 (Colas, 2011). In a limit test, 6 female rats received a single oral dose of 2000 mg/kg bw cobalt aluminium oxide. All animals survived, the body weight gain remained normal throughout the study and no test substance-related clinical signs were observed. Macroscopical examination of the animals did not reveal treatment-related changes at the end of the study.The LD50 cut-off was determined as 5000 mg/kg bw cobalt aluminium oxide.
Justification for classification or non-classification
The available data on acute oral toxicity of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
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.
