Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 inhibiting effect of the test item on the total respiration of activated sludge was observed with five concentrations (100, 200, 400, 800 and 1600 mg/L).
There was no clear dose-response relation of the test item concentration and the inhibition of the consumption rate within the concentration range of 100 to 1600 mg/L. This is probably due to substance specific properties such as poor water solubility and a sticky consistency.
An EC50 could therefore not be determined with the inhibition results of this test.
The EC50 of the test substance was above 100 mg/l.
The NOEC was below 100 mg/l
Key value for chemical safety assessment
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.
