Additional information
No PNEC has been calculated for environmental compartments since negligible exposure of the aquatic /terrestrial/ sedimental environment to 3,3'-[biphenyl-4,4'-diylbis(oxy)]dianiline is expected for the identified use of the substance in the European Union. Microorganisms in sewage treatment plants are also not affected. It should be noted that the water solubility of 3,3'-[biphenyl-4,4'-diylbis(oxy)]dianiline, as determined in accordance with the EU Method A.10, is very low at 0.002 mg/L.
Conclusion on classification
Due to the very low concentrations of residual m-BP in polyimide resins no environmental classification is justified.
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.
