- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- Actual storage conditions: Stored in a dry place in original glass bottle, protected from light at ambient temperature
- Dynamic viscosity of test material:
- visually lowly viscous (suitable for pycnometer method)
- Type:
- density
- Density:
- 902.7 kg/m³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 0.903
- Temp.:
- 20 °C
- Conclusions:
- The substance is much less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method.
Calibration was performed with water. Experiment was performed at 20 °C in duplicate, and the mean density was calculated, and converted to relative density vs water at 4°C.
The density of the test substance at 20 ºC was 902.7 kg/m3. The relative density D20/4 was 0.903.
Reference
Results of the two determinations are reported in the following table:
| Measurement | Determination | |
| 1 | 2 | |
| Temperature (°C) | 20.0 | 20.0 |
| Mass of the empty pycnometer (m0) (g) | 31.4388 | 31.6185 |
| Mass of the pycnometer filled with ultrapure water (m2) (g) | 81.4922 | 81.6504 |
| Mass of the pycnometer filled with the test item (m1) (g) | 76.6923 | 76.8605 |
| Density of the test item (kg/m3) | 902.6 | 902.8 |
| Mean Density (kg/m3) | 902.7 | |
The two determinations are within the validity criteria of the method: (less than 1% of difference).
No additional determination was performed.
The relative density of the test item was calculated to be D20/4 = 0.903.
Description of key information
Experimental density = 902.7 kg/m3 at 20°C. Relative density D20/4 = 0.903.
The substance is much less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.903
Additional information
A fully reliable experimental study, conducted according to a recognized OECD method and under GLP, is available. It is considered as key study, and the result is retained as key data.
