Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriately low concentrations.
Key value for chemical safety assessment
Additional information
The assessment of the toxicity of M3ETB (CAS 926622-96-0) to aquatic microorganisms is based on the experimental data from a GLP short-term respiration inhibition test performed by BASF SE (2018; report no:08G0250/17G331) according to OECD 209. Domestic activated sludge was used as inoculum. No inhibition effect was observed at the highest test concentration (1000 mg/L, nominal). Therefore, the 180min EC10 was determined to be >1000 mg/L.
Based on the experimental data, it can be concluded that the inhibition of the degradation activity of activated sludge is not anticipated when M3ETB is introduced in appropriately low concentrations.
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.
