- Conclusions:
- According to OECD Test Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3. and OCSPP Test Guideline 830.7300 (2002), the relative density D4/20 of the test item fatty acids, C9-C13-neo, barium salts at 20 °C ± 0.01 °C (compared to water at 4 °C) is D4/20 = 1.37.
Reference
Two tests with different amounts of the test item were performed to determine the relative density D420 at a temperature of 20 °C ± 0.01 °C.
Results of the measurement of the density of the test item
| Test No. | Temperature [°C] | Amount of test item [g] | Average sample volume [cm³] | Density [g/cm³]* |
| 1 | 20 | 8.72 | 6.37212 | 1.36846 |
| 2 | 20 | 9.05 | 6.59420 | 1.37242 |
* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.
The mean density of the test item at 20 °C is 1.37044 g/cm³ ± <0.01 g/cm³ (RSD = 0.14 %). The relative density D420 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
The relative density is D420 = 1.37.
Description of key information
According to OECD Test Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3. and OCSPP Test Guideline 830.7300 (2002), the relative density D420 of the test item fatty acids, C9-C13-neo, barium salts at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.37.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.37
