Description of key information

A weight-of-evidence approach was used to address this endpoint. 

Key value for chemical safety assessment

Water solubility:
0 g/L
at the temperature of:
20 °C

Additional information

This assessment relates to the main component, aluminium oxide, and the assessment of the reaction mass based upon its main component can be considered as a worst case approach. Generic issues relating to inorganic substances can be considered as appropriate for all other components within the reaction mass.

Data from the key study conducted in 2010, and weight-of-evidence data from prior studies agree that the water solubility of aluminum oxide is very low (0.00002 g/L at 20 °C).
