1.15 ± 0.19 mg/L at 20.2 ± 2.1 °C 

Key value for chemical safety assessment

Additional information

The water solubility is stated as 1.15 ± 0.19 mg/L at 20.2 ± 2.1 °C (RSD 16.0%) (OECD 105). The value of water solubility for Kaolin, calcined was calculated from the Si content (22.85%) and the measured Si concentrations in water.
