Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EC50 > 100 mg/l, nominal
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
- EC10 or NOEC for microorganisms:
- 100 mg/L
Additional information
A study (1997, Clariant) was performed on a preparation containing sodium salt of similar substance 1. The tested substance did not show any respiration inhibition and the EC50 ( equal to NOEC) is > 100 mg/l. The same result is applicable to Acid black 234
Another study (1988, BASF) tested a preparation containing similar substance 1. The item was tested up to 10g/l without showing any respiratory inhibition with EC0 > 10g/l. Because of the quality of this last study we choose to take the most conservative result of 100 mg/L for Chemical Safety assessment and PNEC caculations.
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.
