Description of key information
Additional information
One valid key study is available to assess the biodegradation in water of Chimexane NB.
This study was performed over a test period of 28 days with a non adapted activated sludge from a predominantly municipal plant according to OECD 301B and EU method C.4-C with GLP statement at Dr. U. Noack-Laboratorien. The biodegradation of Chimexane NB was 58% at the end of the 10-d window and 84% after 28 days. Since the 10d-window does not apply to test substances representing a mixture of homologous compounds as technical surfactants, Chimexane NB is considered as readily biodegradable.
Based on this result, simulation testing on ultimate degradation does not need to be conducted.
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.
