Description of key information

The density of the test material was assessed according to OECD Test Guideline 109 using an Oscillating densitometer. The density of the test substance is 0.978 g/mL at 20 °C and 0.974 g/mL at 25 °C.

Key value for chemical safety assessment

Relative density at 20C:
0.978

Additional information

The density of the test material was assessed according to OECD Test Guideline 109 using an Anton Paar DMA 4500 Digital Density Meter. It is equipped with a U-shaped oscillating tube and meets the requirements of section 11 OECD Guideline 109; Oscillating densitometer (liquids). Prior to analysis, the test substance was heated in a vacuum oven at 60 °C to constant weight to remove any residual volatiles (1-butanol). A 2 mL aliquot of the test substance was inserted into the sample cell after checking the instrument calibration against a NIST traceable toluene standard. A measurement was made at the required 20 °C and also at 25.0 °C which may be needed for MSDS purposes. The analysis was repeated a second time as per OECD Guideline 109. The repeatability is better than 0.0001 g/mL at both temperatures. The experimental and certified density of the NIST traceable toluene standard is 0.86684 and 0.86687 g/mL at 20 °C respectively. This measurement is used to ensure that the instrument calibration is good. The density of the test substance is 0.978 g/mL at 20 °C and 0.974 g/mL at 25 °C.
