Description of key information

The water solubility is < 1 g/L at 20 °C (similar to OECD 105).

Key value for chemical safety assessment

Additional information

The value of water solubility is obtained based on the measurements of four samples taken from the plant of Holcim in Dotternhausen (Germany) (sample P.1034 and P.1082) and plant of ICL Fertilizer Europe C.V. in Arava (Israel) (sample P.1125 and P.1183).

A step-wise test procedure was performed which follows the concept described in Guideline OECD 105. All samples (ca. 0.1 g for each) could not be complete dissolved in 100 ml water after being left for 96 hours. Then the concentration of dissolved portion was determined.
