Description of key information

The relative density (compared to water at 4 °C) is D4R= 3.41 (21.6 °C) (study result, EU A.3 method). The deviation from the nominal temperature (20 °C) does not significantly affect the density value.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

For the evaluation of this endpoint, the result from a guideline conform study (relative density; EU A.3 method) was used as key information supported by data from one other guideline conform study.

The key study was selected on the basis that this study was conducted for the registration under REACH with a sample considered as representative for joint registration of calcium magnesium oxide.
