Additional information
One study (Robama, 2011) was performed on Basic Brown 1 acetate following OECD 202. The substance under the experimental conditions showed an EC50,48h = 0.26 mg/l (Immobilisation). The same order of magnitude of toxicity was observed also for analogue substance 2, confirming that the hazard does not come from the acetic part of the molecule.
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.
