In order to check if the test substance dissolved in the immersion fluid, the density of the immersion fluid was checked before and after the determination with an oscillating densitometer. No significant change was observed, hence no dissolution of the test item occurred.
Description of key information
Relative density: 1.0086 at 20 °C (OECD 109, pycnometer method)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.009
Additional information
The relative density of the test substance 2,2-bis(hydroxymethyl)propane-1,3-diyl didocosanoate (CAS: 68258-72-0) was determined according to OECD guideline 109.
