Additional information
ACUTE TOXICITY - ORAL ROUTE
A good GLP study on similar substance 01, performed according to the OECD Guideline n. 401 is available. The study was
performed to assess the acute oral toxicity of the substance following a single oral administration in the
Wistar rat. The test material was administered by gavage in tap water. There were no deaths. No clinical
signs has been observed. Individual body weights changes were normal and individual necropsy revealed
no abnormalities.
Justification for classification or non-classification
According to the CLP Regulation (EC n. 1272/200/) Table 3.1.1, substances can be allocated to one of four toxicity categories based on acute toxicity.
For the oral route of exposure the Acute Hazard Categories are defined by means of the Acute Toxicity Estimate (ATE) values:
Category 1: ATE ≤ 5 mg/kg bw
Category 2: 5 < ATE ≤ 50 mg/kg bw
Category 3: 50 < ATE ≤ 300 mg/kg bw
Category 4: 300 < ATE ≤ 2000 mg/kg bw
Since the ATE value associated to the substance is > 2000 mg/kg bw therefore no classification is warranted for the dyestuff for acute oral toxicity.
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.
