Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
Data of the structurally related molecule CAS 173011-06-8 are available for the toxicity assessment of the test substance to microorganisms.
CAS 173011-06-8: In a short-term respiration test similar to OECD 209 an EC20 of approx. 1000 mg/L was determined (BASF AG 92/1991/08/11983, 1992). Additionally, in an oxygen consumption test according to DIN 38412 part 27 using Pseudomonas putida an EC10 of >= 1000 mg/L was determined (BASF AG 92/1991/71/1, 1993).
These results are considered to be adaptable for the test substance due to the structural similarities and the identical core-molecules. Based on these values the inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate 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.
