Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance in a saturated solution (approx. 28 mg/L) had no inhibitory effect on the growth of Pseudomonas putida. The increase in growth is not considered relevant in terms of aquatic toxicity. Furthermore, the test is not designed for the evaluation of growth-stimulating effects.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 28 mg/L
Additional information
"Should read: > 28 mg/L"
There was a slight decrease in growth in all concentrations compared to the control. This was not considered to be relevant since there was no clear concentration/effect relationship, wh ich indicated that the variation of the growth was independent of the test substance. Furthermore, the growth inhibition at the two highest concentrations was below 10%, which is only marginal if the EC10 is considered as the toxicity threshold according to the German "DIN standard method".
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.
