Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
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.
