Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There is no test available to specifically evaluate the toxicity towards microorganisms. Therefore, the information of the toxicity control included in the ready biodegradation assay was used to evaluate this endpoint. The toxicity control in the CO2 Evolution test showed no inhibition of the microbial activity at a substance concentration of 59.3 mg/L, no further test is necessary to evaluate the respiration inhibition of activated sludge as the concentration used in the toxicity control (59.3 mg/L) can be used as NOEC value.
According to the ECHA Guidance document R7b, no further test on the toxicity to microorganisms has to be conducted if the toxicity control in a ready biodegradability test shows no inhibitory effects on microorganisms.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 59.3 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.
