Additional information

The water solubility of the test compound was determined experimentally in compliance with EU Method A.6 of Commission Directive 92/69/EEC. The determination was carried out using the Flask Shaking Method. Based on the preliminary result, aliquots of test material were weighed into three separate flasks. After addition of glass double-distilled water to the flasks, they were shaken at approximately 30°C and, after standing at 20°C for a period of not less than 24 hours, the contents of the flasks were centrifuged, filtered and the concentrations of phosphorus determined by ICPES. Data supplied by the Sponsor indicated that the test compound contained 6.9 % phosphorus. This figure was used to convert concentration of phosphorus to concentration of test material. The water solubility of the test compound has been determined to be 1.72 g/L of solution at a temperature of 20.0 ± 0.5°C.
