Type:

density

Density:

1.23 g/cm³

Temp.:

20 °C

Density Test 1: 1.232 g/cm³

Density Test 2: 1.230 g/cm³

Mean density: 1.23 g/cm³

Conclusions:

A relative density at 20 °C (compared to water at 4 °C) of 1.23 was measured for the tested substance (OECD Guideline 109, air comparison pycnometer method).

Description of key information

Relative density at 20 °C (compared to water at 4 °C) = 1.23 (OECD Guideline 109, air comparison pycnometer method).

Key value for chemical safety assessment
