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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is miscible in all proportions in distilled dionised water at ambient temperature, 10°C and 30°C. The substance is also miscible in all proportions at pH 5 and pH 9 buffer solutions at ambient temperature.
Key value for chemical safety assessment
Additional information
Two studies are available on the water solubility. Both studies are reliable and were conducted under GLP according to current guidelines. The two studies showed that the substance is freely soluble in water. The key study is considered to be the one conducted on the test substance of 98.55% purity and the one which additionally examined the effects of temperature and pH on the water solubility.
The water solubility of the test substance could not be assessed using the column elution or flask methods due to its high water solubility/miscibility. Therefore a visual assessment of the water solubility of the test was carried out. Temperature and pH were not found to affect the solubility of the substance.
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.
