Description of key information
The water solubility of the substance was determined using the slow-stirring-flask method based on EC A.6, OECD 105 and OPPTS 830.7840. The study was performed directly at the test temperature of 20°C. Since the test item is an UVCB substance, the main study was performed at loading rates of 1 g/L (low loading rate) and of 10 g/L (high loading rate). Quantification was performed by UPLC-MS/MS. The pH of the aqueous samples was 3.2 and 2.5, at the low and high loading rate, respectively. The water solubility of the substance at 20°C, at low and high loading rate, was determined to be 0.749 and 3.40 g/L based on the mono-ester and 0.00331 and 0.00283 g/L based on the di-ester.
Key value for chemical safety assessment
Additional information
There is no defined value for the water solubility of this UVCB substance nor can it be derived. Many components will have a very low solubility, while others may have a high solubility.
Based on the composition of the substance and the results obtained during the development of the method for the quantitative analysis of the substance in water and from the water solubility study, it can be concluded that the substance mostly is poorly soluble in water.
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.
