Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 appropriate low concentrations.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
Additional information
A study on a close structural analogue(CAS 16090 -02 -1) is available in order to determine the toxicity of the substance to microorganisms. The study demonstrates that the substance does not inhibit the degradation activity of activated sludge in concentrations lower or equal than 100 mg/L.
It is assumed that also the substance with CAS 133-66-4 does not inhibit the degradation activity of activated sludge.
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.
