Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 toxicity of the substance to microorganisms was determined as part of a toxicity control in a ready biodegradability study according to OECD TG 301B and GLP. In this study, activated sludge (obtained from a wastewater treatment plant treating domestic wastewater) was exposed to 80.3 mg/L sodium acetate (positive control) with and without addition of 36.0 mg/L of the test substance in 2 liters of test medium. In the toxicity control more than 25% degradation occurred in 14 days (based on ThCO2). Therefore, the test substance was assumed to be not inhibitory. Based on these findings, the NOEC for microorganism toxicity is determined at 18 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 18 mg/L
Additional information
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.
