Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
The key study (Daniel, 2012) was performed under GLP conditions and in accordance with standardised guidelines. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as defined by Klimisch (1997). Under the conditions of the test <10 % inhibition was observed at all concentrations, this was considered to be within the expected experimental variability of the test and was considered not to be an effect of exposure to the test material. Since no inhibition was observed up to the maximum concentration of 1000 mg/L, the NOEC and EC50 were determined to be 1000 mg/L and > 1000 mg/L, respectively.
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.
