Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
At 20°C and at pH ca. 6.7 the solubility was found as follows:
- Values analyzed by TOC:
2.8 mg/L with a loading rate of 0.1 g/L
14.5 mg/L with a loading rate of 1.0 g/L
- Values analyzed by Cr-content:
<1.8 mg/L with loading rate of 0.1 g/L and 1.0 g/L
Key value for chemical safety assessment
Additional information
The determination was performed by flask method according to OECD Guideline 105.
The test item is a complex mixture. The water solubility can therefore only be investigated via determination of dissolved amounts of chromium, nitrogen and carbon contained in the test item.
The different results show that the water solubility of the test item is dependent on the method of analysis and the amount of test substance added.
The results quantified by TOC and by Cr-content could be considered suitable for using this endpoint and further assessment, 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.
