According the OECD 105, the water solubility at both flow rates yielded values below the limit of quantification (LOQ).
The water solubility of the test item was determined as < 3 μg/L.
The water solubility was determined at 20 °C. The pH value of the collected aqueous fractions was 6.3.
pH value of HPLC water: 6.3
Applicant's summary and conclusion
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.
