Temp.:

relative density is calculated to water at 4 °C:

rel dens = Density (g/mL) / Density of water at 4 °C ( 0,999975 g/mL) = 1.003 g/mL / 0.999975 g/mL = 1.003

Conclusions:
Density at 45°C = 1.003 g/mL
Executive summary:

The density at 45°C of the test substance was determined to be 1.003 g/mL in a non-GLP test according to OECD 109. Relative density of the substance at 45 °C to water at 4 °C is 1.003.

Description of key information

 The density at 45°C of the test substance was determined to be 1.003 g/mL in a non-GLP test according to OECD 109. Relative density of the substance at 45 °C to water at 4 °C is 1.003. 

Key value for chemical safety assessment

Relative density at 20C:
1.003

Additional information

The density at 45°C of the test substance was determined to be 1.003 g/mL in a non-GLP test according to OECD 109. Further, the density of the test substance is reported to be 1.008 g/cm3 at 47 °C [GESTIS substance database], which confirms this experimental result.

Relative density was not at 20 °C, but at 45 °C, but the determined value at 45 °C is applicable for CSA.
