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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Solubilities at 20°C and at pH 6.2 were found as follows:
54 mg/L with a loading rate of 0.1 g/L
167 mg/L with a loading rate of 0.5 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. Thus, the water solubility of the test item was investigated via determination of dissolved amounts of chromium and carbon.
The results of both method are deemed to be consistent. As the values quantified by TOC can be affected by a small amount of impurities therefore the values quantified by Cr content has been chosen for using this endpoint and further assessment.
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.
