Conclusion on classification
o-Toluidine is legally classified as dangerous for the environment and so included in Annex I of Directive 67/548/EEC and in Regulation 1272/2008 (CLP), including its 2nd and 3th ATP.
Daphnia magna were found to be the most sensitive aquatic species.
The lowest value on acute aquatic toxicity is an 48h-EC50 of 0.12 mg/L.
Concerning long-term toxicity the lowest value is a 21d-NOEC of 0.011 mg/l.
The substance is readily biodegradable and the log Kow is 1.4 (exp. result).
Regarding acute toxicity, o-Toluidine is classified according to Directive 67/548/EEC as R50 and according to Regulation (EC) No 1272/2008 as Aquatic Acute Category 1 and an M-factor of 1 is assigned.
Regarding chronic toxicity, o-Toluidine is classified according to Regulation (EC) No 1272/2008 as Aquatic Chronic Category 1 and an M-factor of 1 is also assigned.
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.
