Description of key information
Water solubility: 385.6 ± 1.1 mg/L test item based on P and 233.1 ± 2.4 mg/L based on non purgeable organic carbon at 20.9 +/- 0.1 °C
Key value for chemical safety assessment
Additional information
Under the conditions of this test (flask method; loadings of 1.882 g/L and 1.872 g/L test item in vessel 1 and 2, respectively), a solubility equilibrium was observed during the testing (days 1 – 3).
The pH in test item loaded vessels decreased to 3.7 – 3.9 whereas the pH in method blanks was in the range of 7.5 – 7.8. The mean temperature throughout the test was 20.9 ± 0.1°C.
The mean amount of dissolved phosphorous was 54.18 ± 0.15 mg/L P and the amount of dissolved C was 34.83 ± 0.36 mg/L (determined as dissolved P and NPOC, separated by filtration from undissolved test item).
This corresponds to calculated dissolved test item mean concentrations of 385.6 ± 1.1 mg/L test item based on P and 233.1 ± 2.4 mg/L based on non purgeable organic carbon.
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.
