Description of key information
Relative density at 20 °C is determined as 2.6 for solid and 1.49 for an aqueous solution (38.3%).
Key value for chemical safety assessment
Additional information
The key values of relative density are determined according to OECD guideline 109 under GLP. Relative density at 20 °C is determined as 2.6 for solid (Baltussen 2010) and 1.49 for an aqueous solution (38.3%) (Brekelmans 2010). Test results refer to sodium aluminate (NaAlO2) containing excess disodium oxide (Na2O) as stabiliser.
Density reported in peer reviewed handbook (Lide 2005): 4.63 g/cm3 (temperature is not stated).
