- ca. 0.993
- Temp.:
- 20 °C
- Conclusions:
- The relative density is 0.9925 +/- 0.0008 at 20°C.
- Executive summary:
Relative density of Fatty acids, C16-18 and C18-unsatd., compds. with triethanolamine was determined according to test procedure L 142 A/21-25 (A.3.) and OECD Guideline 109. Relative Density was determined at 20 °C by using the pycnometer method.
The relative density of Fatty acids, C16-18 and C18-unsatd., compds. with triethanolamine was determined to D204 = 0.9925 + 0.0008 at 20 °C. (N=3, P:95%)

The relative density D204 of solids and liquids is the ratio between the mass of a volume of substance to be examined, determined at 20 °C, and the mass of the same volume of water at 4 °C. The relative density has no dimension.
Description of key information
The relative density was determined to be 0.9925 +/- 0.0008 at 20°C.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.993
