Details:

To verify the insolubility of the test item in the immersion liquid, the density of the immersion liquid “Shellsol T” was measured before and after the determination.

 

ρ(Shellsol T (20 °C) before determination (g/cm3) : 0.760

ρ(Shellsol T (20 °C) after determination (g/cm3) :  0.759

 

No significant change in density was observed. Under the conditions used for the determination (temperature, incubation time) the test item is insoluble in the immersion liquid.

Description of key information

Relative density: 0.94 at 20°C

Key value for chemical safety assessment

Relative density at 20C:
0.94

Additional information

A relative density value of 0.94 at 20°C was determined using the pycnometer method according to EU Method A.3. This is supported by a measured density value of 0.8–0.9 g/cm3at 20°C.
