Additional information
Acute toxicity of Acid Brown 282 to invertebrates was investigated in two 48 hours tests, in which the following nominal concentrations were tested: 0.1, 1.0, 10 and 100 mg/l. Two vessels were used as vehicle control and further two vessels as blank control. In both cases, the EC50 after 48 hours was recorded as higher than 100 mg/l (Huntsman Textile Effects (Germany) GmbH 1995 and 1996).
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.
