Measurement	Density at 20°C (g/cm^3)	Relative Density D^204^(1)
Test 1	0.98912	0.98915
Test 2	0.98912	0.98915
Mean value	0.989	0.989

 

⁽¹⁾ The relative density D²⁰₄ 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).

 

Conclusions:

A density of 0.989 g/cm³ at 20°C and a relative density of 0.989 were determined in a reliable study conducted according to an appropriate test protocol. It was not conducted according to GLP.

A density value of 0.97 g/cm³ at 25°C was obtained for the substance using an appropriate calculation method. The result is considered to be reliable.

Description of key information

Relative density: 0.989 at 20°C (measured)

Key value for chemical safety assessment

Relative density at 20C:

0.989

Additional information

A relative density value of 0.989 at 20°C (1013 hPa) was determined using an oscillating densimeter according to OECD Guideline 109. This is supported by a predicted density of 0.97 g/cm³ at 25°C obtained for the substance using an appropriate calculation method. The result is considered to be reliable. Additional supporting values of 0.996 g/cm³ at 20°C and 0.99 g/cm³ at 25°C were obtained from secondary sources (company data), although the reliability of the data is unassignable. The supporting results are in good agreement with the key study.
