*The relative density D20/4 is the ratio between the measured density of the test substance at 20°C and the density of water at 4°C (= 0.99997 g/cm3). The relative density has no dimension.

 Check measurement: Density of degassed deionized water at 20°C: 0.99820 g/cm3

Reference value: 0.99820 + 0.00050 (20°C)

Conclusions:
A relative density value of 1.014 at 20°C was determined for the substance using a relevant test method. The result is considered to be reliable.

Description of key information

Relative density: 1.014 at 20°C (OECD 109)

Key value for chemical safety assessment

Relative density at 20C:
1.014

Additional information

A measured relative density value of 1.014 at 20°C was obtained using an oscillating densimeter in accordance with OECD Test Guideline 109 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.

A predicted density value of 0.97 g/cm3 at 20°C was determined for the substance using a validated QSAR estimation method.

In available secondary sources to which reliability could not be assigned, density values of 1.02 g/cm3 at 20°C and 1.014 g/cm³ at 25°C were reported for the substance.
