Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
All three acute trophic levels were assessed either with study on the substance itself or with reliable Read Across studies on analogous substances. EC50 was always measured as higher than 100 mg/l.
Regarding long term studies, a Daphnia magna reproductive study is available on the similar substance 16470-24-9. The substance is the analogous substance dihydroxyethylamino derivative tetrasulphonated sodium salt. The result of the chronic reproductive Daphnia study on the analogous substance CAS 16470-24-9 has been considered to establish the NOEC for the substance (NOEC = 6.59 mg/l).
No further long term studies are proposed, since direct and indirect exposure is unlikely due to the risk management measures that will be applied at industrial level and discussed in details within the exposure scenario to avoid any release of the substance directly in the municipal waste water treatment. The local RCR in surface water is calculated to be lower than 0.01 and 0.0052 based on estimated and monitored quantities, 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.
