- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- experimental dates: 13/11/2017 to 30/11/2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- Storage conditions: closed original container (metal bottle) at 2 – 8 °C
- Dynamic viscosity of test material:
- No data. Test item warmed to 80°C to be flowable.
- Type:
- density
- Density:
- 0.945 g/cm³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 0.945 other: relative density (d20/4) has no dimension
- 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, using a saturated aqueous solution as replacement liquid.
Due to wax-like appearance of the test item, it was warmed to 80°C to handle it; then experiment was performed at 20 °C in duplicate, and the mean density was calculated.
A density of 0.9452 ± 0.0007 g/cm3 at 20.0 ± 0.4 °C was measured.
The relative density (d20/4) of the test substance was calculated to be 0.9452.
Reference
| Determination | Temperature | Density of water (g/cm3) | Density of replacement liquid | Denstity of test item (g/cm3) |
| 1 | 20.0 °C | 0.998203 | 0.9983 | 0.9460 |
| 2 | 20.4 °C | 0.998098 | 0.9982 | 0.9445 |
| Average | 0.9452 (SD = 0.0010) |
Relative density = 0.9452
Description of key information
The substance is much less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.945
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study, and the result is retained as key data.
